Important Safety Instructions

WARNING: High Energy and High Voltage

Exercise caution when using and calibrating a power supply.

High energy levels can be stored at the output voltage terminals

on a power supply in normal operation. In addition, potentially

lethal voltages exist in the power circuit and on the output and

sense connectors of a power supply with a rated output greater

than 40 V. Filter capacitors store potentially dangerous energy

for some time after power is removed.

CAUTION

Operate the power supply in an environment free of flammable

gases or fumes. To ensure that the power supply’s safety

features are not compromised, use the power supply as specified

in this manual and do not substitute parts or make any

unauthorized modifications. Contact the service technician for

service and repair help. Repairs must be made by experienced

service technicians only.

Changing Internal Jumpers

Some of the settings on the Ethernet/RS-232 Interface card are user

selectable by way of jumpers on the printed circuit board. The procedure

for changing the jumpers varies depending on if you have a 1.2kW XFR,

or a 2.8kW XFR.

CAUTION

If you remove the unit's cover, use proper static control

techniques to avoid damage to static-sensitive components on

the printed circuit board.

Procedure for 1.2kW XFR

Ensure that the input power connection has been disconnected and the

unit is powered off before you attempt to remove the top cover. Remove

all the screws holding down the top cover and then remove the cover. The

printed circuit board that you need access to is upside down (component

side down), so you must remove all the screws that are holding it in place.

Installation and Configuration

Configuring for Ethernet or RS-232

This interface card can be configured for Ethernet communication, or for

RS-232 communication, but not both simultaneously. From the factory,

the instrument will be configured for Ethernet communication. Therefore

you should only need to follow these instructions if you are switching

over to RS-232, or back to Ethernet. To switch between the two

configurations, you must change internal jumpers on the interface card.

See “Changing Internal Jumpers” on page 2–8. Also refer to Table 2-2

and Figure 2-3 on page 2–6 to locate the corresponding jumpers.

Table 2-5 Jumper positions for Ethernet or RS-232

1-2

2-3

When you have finished changing the jumper positions, ensure that the

baud rate, flow control, and power-on state are configured properly for

your new setup. These settings are also changed by adding or removing

jumpers, so it is best to perform this adjustment, if necessary, while the

interface card is accessible. Refer to “Baud Rate Selection” on page 2–18,

“Flow Control Selection” on page 2–19 and “Remote/Local Mode

Startup” on page 2–20 for more detailed information on how to

reconfigure these settings.

Note: If you are switching the interface card back to Ethernet it is

recommended to set the baud rate to 9600, turn flow control off, and

have the unit power-on in remote mode (these are the default settings).

2–12

TM-XR9B-01XN

Ethernet Communications

Ethernet Connection

There are two options for controlling your XFR power supply via

Ethernet - "Connecting to a Network" or "Connecting Directly to your

Computer." The first option is to connect the power supply to a network,

and control the unit from your computer which is also connected to the

network. The second option is to connect the XFR directly to your

computer's network interface card (NIC). This bypasses the need for an

existing network.

Connecting to a Network

All that is required to connect your XFR to a network is a straight through

CAT 5 network cable and an available network port.

Connecting Directly to your Computer

To connect your XFR directly to your computer you will need a cross-

over CAT 5 network cable. You will also need to check your network

settings on your computer to ensure that you are using a static IP address.

Check with your IT department for assistance.

TM-XR9B-01XN

2–13

Installation and Configuration

Locating the Power Supply on Your Network

1. Record the MAC address for your power supply. This will be visible

at the back of the XFR, on the interface card subplate. For example,

MAC Address

00429D 22EF45

MAC Address:

______________________________

2. Insert the Xantrex XFR Ethernet Software Utilities CD into your CD

drive.

3. If the CD does not start automatically, double-click the My Computer

icon, double-click the CD icon and then double-click

autorun_main.htm.

4. When the menu appears, click Xantrex Device Discovery to install

and run the application. This application will find and list all XFR’s

with an Ethernet/RS-232 Interface card on your network.

5. You can now scan the list and locate your new XFR by its MAC

address.

6. If your network uses a DHCP server and DHCP was enabled on the

XFR, your new instrument will already have an IP address. If not, you

will have to configure an IP address manually. Refer to steps 2 and 3

in “Configuring Ethernet Bridge” on page 2–15 for more information.

7. Write down the IP address so that you can access the instrument via

its web server, and for when you start communicating with the power

supply.

TM-XR9B-01XN

Ethernet Communications

Configuring Ethernet Bridge

The Ethernet/RS-232 Interface card has an Ethernet Bridge that converts

the ethernet packets to serial data signals for processing by the embedded

microcontroller. The Ethernet Bridge must be properly configured for

serial communications with the microcontroller. For example, settings on

the Bridge, such as Baud Rate and Flow Control, must match the jumper

settings on the interface board.

There are two ways to gain access to the configuration menu for the

Ethernet Bridge. One is to run the Setup program that is available on the

Software CD. This program will find your instrument and allow you to

configure it by clicking on the instrument’s IP address. You will then need

to enter the correct username and password to be able to configure the

device.

Default Username: root

Default Password: dbps

The other method is to open up a web browser like Internet Explorer, and

type in the IP address for the instrument. Again, you will be asked for the

username and password. Once you have accessed the configuration page,

follow these steps for proper setup.

1. Click Configuration > Serial Port, and ensure that the following

settings have been selected:

•

Baud Rate:

Data Bits:

Parity:

Stop Bits:

Flow Control:

9600

None

Click Apply once you have finished adjusting the above settings.

2. Now click Configuration > Network. If your network uses a DHCP

server (ask your IT department) you should select Obtain IP address

automatically using DHCP and then click Apply. If your network

doesn’t use a DHCP server, select Use the following IP address: and

enter an appropriate IP address, Subnet Mask and Default Gateway. .

3. Ask for assistance from your IT department to obtain an appropriate

IP address, Subnet Mask, Default Gateway, Name Server, and

Domain. Once you have made the appropriate changes, click Apply. If

this changed the setting, the device will reboot, so you will have to

renew your connection to its configuration webpage for any further

configuration changes.

Installation and Configuration

Installing and Using RealPort®

Background

RealPort® software allows you to keep using your existing applications

that rely on COM ports and RS-232 links for communication purposes,

instead of having to develop TCP/IP based network applications. Installed

on a network-enabled PC, RealPort® creates a virtual COM port. As

such, your application still thinks it is working with a real serial port, such

as COM1. When the application sends data to this serial port, RealPort®

ships the data across the network to the Ethernet Bridge in your power

supply. By doing this, the network is transparent to your existing

application.

Installation

RealPort® can be installed on any PC running Windows NT 4.0,

Windows 2000, or Windows XP.

1. Insert the Xantrex XFR Ethernet Software Utilities CD into your CD

drive

2. If the CD does not start automatically, double-click the My Computer

icon, double-click the CD icon and then double-click

autorun_main.htm.

3. When the menu appears, click Digi RealPort®.

4. Follow the on-screen instructions for proper installation.

Note: RealPort® drivers for UNIX systems are available. Contact your

Xantrex representative to obtain these drivers if necessary.

Using RealPort®

Once you have installed the RealPort® driver for your power supply,

using it is as simple as running your existing application (such as

HyperTerminal, or a custom RS-232 application) and setting the COM

port to be the one created by the RealPort® driver for your instrument.

signaling that the power supply is under the control of the digital interface

card. The output of the power supply is active on startup. To promote load

safety, power ON defaults are zero for the output voltage and current

limit, and 110% of maximum output voltage for the OVP trip point. See

Table 2-10. Refer to “Operation” for more information about the interface

commands listed in the table.

If the PON REM jumper is closed, the power supply will power up in

local mode. Power supply control is at the front panel. During an

operating session, you can toggle between local mode and remote mode

by using the front panel LOCAL button or sending commands as

described in Table 2-10.

Note: The default setting for this jumper is open. If you require it to be closed

of device-dependent commands available with this interface.

From remote mode, change to local mode operation by pressing the front

panel LOCAL button or by sending either the GTL command or the

REN OFF command. You can disable the LOCAL button by using the

LLO command. For an example of how to use Local Lockout, see “Local

Lockout (LLO) Command” on page 2–23.

To return to remote mode, ensure that the REN command is set to ON and

then send any valid device-dependent command. Since the remote mode

output settings may be different from the local mode settings, the output is

programmed to protect the load by turning off when you toggle from local

to remote mode during a session. Check your remote settings and then

send OUT ON to restore the output.

TM-XR9B-01XN

2–21

Installation and Configuration

Local Mode Operation

In local mode operation, you set the voltage and current output levels and

the OVP trip level with controls located on the front panel. Refer to the

operating manual for a description of the functions available at the front

panel.

While in local mode operation, you can change power supply control to

remote mode by ensuring that REN is ON, then sending any software

command and OUT ON to restore the output. Return to local mode by

pressing the front panel LOCAL button, unless Local Lockout is in effect.

If LLO is in effect, use the GTL command to send the power supply into

local mode, or use the REN OFF command to turn off LLO and return the

power supply to local mode.

Example:

Press the LOCAL button

Id?

Set unit to local mode

Put the unit into remote mode

(Use any command to do this.)

Press the LOCAL button

Return to local mode.

Remote Enable (REN) Command

You can use the Remote Enable command to toggle between local mode

and remote mode. The default setting at startup is REN ON. With the

remote enable command set at REN ON, you can return the power supply

to remote mode whenever you send any command from the computer.

Any time that you change from local to remote mode during a session, the

output is programmed to turn off, since the remote mode settings may be

different from the local mode settings. Send the OUT ON command to

restore the output.

You can turn off Remote Enable and move power supply control to the

front panel by sending the REN OFF command. If the Local Lockout

condition is in effect, sending the REN OFF command will turn off the

LLO condition before sending the unit into local mode.

To check whether the power supply is remote enabled, use the REN?

query command.

Example:

REN ON

Installation and Configuration

Additional User Options and Settings

You can customize remote operation settings for OVP (over voltage

protection) control and TTL shutdown by changing jumper positions on

the Ethernet/RS-232 Interface card. Refer to the operating manual for

information on how to use over voltage protection and TTL shutdown.

OVP Selection

Over voltage protection (OVP) on the Ethernet/RS-232 Interface is set at

the factory for remote software operation. When operating the power

supply in remote mode, you control the OVP trip level using the OVSET

software command. If you return the power supply to local operation by

using the REN software command or the front panel LOCAL switch,

control of the OVP trip level changes from software control to the front

panel OVP potentiometer. The default OVP trip level is set as 110% of the

power supply's rated output voltage. See Table 2-10 on page 2–21 for a

complete list of remote power ON default settings.

You can isolate the location of OVP control by changing the positions of

the Local OVP Control jumper J65 and the Remote OVP Control jumper

J103, both on the Ethernet/RS-232 Interface PCB. The default jumper

settings allow control of OVP to depend on the operating state of the

power supply. By physically changing the jumper settings, you can isolate

Additional User Options and Settings

TTL Shutdown Polarity

You can use the Shutdown function to disable or enable the supply's

output. Disabling the supply using TTL shutdown allows you to make

adjustments to the load or to the power supply without shutting down the

power supply. With the Ethernet/RS-232 Interface installed, TTL

shutdown is activated by a TTL signal to Pin 1 of the user lines connector

on the interface subplate. The shutdown user line uses a 0-5Vdc TTL

input with a high signal range of 2.2-5.0Vdc. The current range of the

shutdown line is 1-10mA. See Figure 2-6, “User Lines Signal Connector

Circuit Block Diagram” on page 2–27 for a schematic of the user lines

connector containing the shutdown user line.

You can select the logic level of the TTL input by changing the J93

connector on the Ethernet/RS-232 Interface PCB. Table 2-13 shows the

TTL signal levels for the J93 jumper settings. See Figure 2-3 for the

location of the J93 jumper on the printed circuit board. You will need to

remove the cover to change any jumpers. See “Changing Internal

Jumpers” on page 2–8.

Installation and Configuration

User Signals

User Lines Connector

Auxiliary User Lines connector, located on the Ethernet/RS-232 Interface

rear panel, provides several signals to increase your operating control of

the supply. These signals are dependent on the operator's design and uses.

The operation of the user lines connector signal requires that you provide

external Vcc and ground. Use a standard 8-position telephone jack and

data cable to connect to the user lines connector. To locate the connector,

refer to the Ethernet/RS-232 Interface subplate drawing in Figure 2-2 on

page 2–5. See Table 2-14 for pin descriptions. The user lines connector

outputs can sink a current of 5mA each. Figure 2-6 on page 2–27 shows

the portion of the option board schematic which contains the user line

connector. Use the schematic as a reference when making input or output

connections.

Installation and Configuration

User Lines Cable Connection

Use a standard 8-position telephone jack and data cable to connect to the

user line connector. Add a ferrite block to reduce radiated emission. The

one inch square ferrite block with built-in housing clip is packaged and

shipped with the power supply interface card.

To install the ferrite block:

1. Position the block no more than 5 cm (2 in.) from the power supply

end of the user line connector cable.

2. Open the ferrite block housing.

3. Loop the cable through the ferrite block. See Figure 2-7, “User Lines

Cable with Ferrite Block” on page 2–28.

4. Close the housing clip.

The ferrite block ensures that the power supply system meets radiated

emission requirement 89/336/EEC for CE mark approval. See the power

supply's operating manual for noise specifications.

Operation

Introduction

This section covers Ethernet/RS-232 Interface programming, including

an extensive set of device-dependent commands, error codes, and status

and fault register information.

Operation

RS-232 Operation

When the Ethernet/RS-232 Interface card is configured for RS-232 you

can send and receive data between your power supply and computer,

relying on bit serial communication. You can use the computer controller

to issue commands to the power supply for programming, queries,

calibration, or status. The power supply responds to the complete

command set of device dependent software commands shown in

“Command Reference” on page 3–9.

Ethernet Operation

When the card is configured for Ethernet, you can send and receive data

between you power supply and computer via your network. The same

command set is used for RS-232 and Ethernet. The only difference is

medium and protocol used.

Command Syntax

Manual Conventions

The manual uses these conventions when displaying command

information. These characters are not part of the command but are used to

denote parameters used with the command.

< > (angle brackets)

Angle brackets enclose a parameter. Do not include

the angle brackets in the command line you send to

the computer.

/ (slash)

Separates two alternative parameters. When a slash

separates two parameters, you can use either

parameter to achieve the same result.

Example: <1/ON>

Entering 1 or ON will achieve the same result.

TM-XR9B-01XN

Command Syntax

Command Format and Parameters

The device-dependent language for the Ethernet/RS-232 Interface

consists of commands and parameters. A command is a one word code

which either gives instructions to the interface or asks for information

from the interface. A command may be followed by one or more

parameters, a short code that changes the state of the power supply or the

state of the bit register. Table 3-1, “Command Parameters” on page 3–4

lists the parameters that affect the command set.

Format:

COMMAND or

COMMAND <parameter> or

COMMAND <parameter>,<parameter>

•

You can enter commands in upper or lower case lettering.

Example: MASK FOLD = mask fold

Do not further abbreviate command names or parameters.

Example: MASK FOLD ≠ MK FOLD

MASK FOLD ≠ MASK FD

•

Use a space between the command and the first parameter. Any

number of consecutive spaces is treated as one space. Numeric data

may contain leading spaces. Embedded spaces between digits or

between a digit and a decimal point are not accepted.

Example: MASK FOLD = MASK

VOUT 3.4 = VOUT

FOLD

3.4

VOUT 3.4 ≠ VOUT 3.

•

Use commas between parameters in those commands with more than

one parameter, and between mnemonic parameters as in the MASK

and UNMASK commands. Only one comma is allowed and it may be

preceded or followed by any number of spaces.

Example: MASK CV, OV, FOLD

Command Syntax

Command Strings

If you send more than one command line, separate the commands with a

semicolon. The semicolon may be preceded or followed by spaces.

Example:

ISET 2.0A; VSET 5V

Command Terminators

Terminators indicate the end of a command string and tell the power

supply to execute the command. The termination character is CR

(Carriage Return).

Format:

COMMAND <parameter>; COMMAND <parameter>,

Order

You may send commands in any order, keeping in mind that only those

commands received after a HOLD and before a TRG (trigger) will be

released by the TRG command. In addition, only these commands

received after a supply disable (OVP or foldback protection) and before a

RST (reset) or OUT ON command will be released by the RST command

or the OUT command. Commands are executed in the order they are

received.

stores any bit that was entered in the status register since the accumulated status

query command (ASTS?) was last used, regardless of whether the condition still

exists. The accumulated status register has the same bits, weights, and conditions

as the status register. A bit in the accumulated status register will be set at 1 if the

corresponding bit in the status register has been 1 (TRUE) at any time since the

page 3–17. The ASTS? query clears the status register.

Response: CMODE 0 (disabled)

CMODE 1 (enabled)

TM-XR9B-01XN

3–9

Operation

Table 3-7 Command Reference

DLY <seconds> Sets a programmable time delay employed by the supply before reporting fault

conditions. The power supply uses the time delay after receiving a new output

voltage or current setting via VSET or ISET, or after receiving RST, TRG, or OUT

ON commands. During the time delay, the power supply disables CV, CC, and

FOLD conditions from generating faults, preventing possible nuisance foldback if

the supply momentarily switches modes while changing an output setting.

Range: 0 to 32 seconds, with 32ms resolution

Initial value: 0.5 second

DLY?

ERR?

Asks for the setting of the programmable time delay before the supply reports fault

conditions.

Response: DLY <seconds>

Asks for the most recent remote programming error. When the power supply

detects a programming error, it lights the ERR LED and sets the ERR bit in the

accumulated status and fault registers. If the error bit has been masked using the

MASK command, then the ERR bit in the registers will not set. Once an error is

detected, the remaining portion of the command line is discarded. An error query

clears the ERR bit in the accumulated status register. See “Error Codes” on page 3–

19.

Response: ERR <error number> Example: ERR 0 (if no error)

FAULT?

Asks for the state of the fault register. A bit is set in the fault register when a fault

arises for that condition. Lists the conditions which activate a fault bit. You can use

the MASK command to disable bits from being set in the fault register.

When a bit is set in the fault register it also asserts a signal on the Pin 4 user signal

line. You can tie the Pin 4 fault line signal to the power supply's own External

Shutdown user line, Pin 1, so that the shutdown signal goes low (active) in the case

of a user-defined fault.

The FAULT? query clears bits in the supply's fault register and fault line.

Response: FAULT <fault mask> where fault mask is the decimal equivalent of the

total bit weights for the operating conditions as listed in the fault register. See

“Accumulated Status, Status, and Fault Registers” on page 3–17.

FOLD

Sets foldback mode for the supply. Foldback protection disables the power supply

<2/CC>, <1/CV>, output when the output enters the fold condition. Reset with the RST command.

<0/OFF>

Example: Specify FOLD 1 or FOLD CV (Constant Voltage) when you want the

supply to operate in Constant Current mode and have foldback protection disable

the output if the supply switches to Constant Voltage mode.

Initial value: FOLD 0/OFF

3–10

TM-XR9B-01XN

Command Reference

FOLD?

Asks for the supply’s present foldback setting.

Response: FOLD <mode> where mode is:

0 (OFF) or

1 (CV or Constant Voltage mode) or

2 (CC or Constant Current mode)

GTL

Go to local. Returns the power supply to local control. See LLO (Local Lockout).

See also“Remote/Local Operation” on page 2–20.

HOLD <1/ON>, Enables or disables voltage/current setting hold mode for the supply. When

<0/OFF>

HOLD ON is specified, hold mode is enabled so that all voltage and current

settings which would normally be implemented by the supply are held until a TRG

(trigger) command is received. This feature allows you to synchronize the

operation of several supplies.

Initial value: HOLD OFF or HOLD 0

HOLD?

ID?

Asks for the present hold mode setting.

Response: HOLD 0 (OFF or disabled) or HOLD 1 (ON or enabled)

Asks for the power supply model and the master EPROM version.

Response: ID <model name><version>

IDATA

IHI data. Set CMODE ON before using this command. See also the calibration

procedures in Chapter 4.

<Ilo> and <Ihi> are in <current> format.

IHI

In response to this command, the power supply sends a programmed current value

to the output terminal. This value is at the high end of the power supply’s current

range and is read by an external device connected as part of the calibration

procedure. Refer to this value as IHI and record it to use as input with the IDATA

command. Set CMODE ON before using this command. See also the calibration

procedures in Chapter 4.

ILO

In response to this command, the power supply sends a programmed current value

to the output terminal. This value is at the low end of the power supply’s current

range and is read by an external device connected as part of the calibration

procedure. Refer to this value as ILO and record it to use as input with the IDATA

command. Set CMODE ON before using this command. See also the calibration

Operation

Table 3-7 Command Reference

VRHI

The power supply outputs a voltage value to an external voltmeter connected as

part of the calibration procedure and records a voltage readback value internally.

These values are at the high end of the programmed voltage range. Refer to the

output value as VRHI and record it to use as input with the VRDAT command. Set

CMODE ON before using this command. See also the calibration procedures in

Chapter 4.

VRLO

The power supply outputs a voltage value to an external voltmeter connected as

part of the calibration procedure and records a voltage readback value internally.

These values are at the low end of the programmed voltage range. Refer to the

output value as VRLO and record it to use as input with the VRDAT command. Set

CMODE ON before using this command. See also the calibration procedures in

Chapter 4.

VSET <voltage> Sets the power supply’s output voltage in volts (default) or in millivolts. This

or programmed voltage is the actual output in CV (constant voltage) mode or the

VSET <-voltage> voltage limit in CC (constant current) mode.

If you enter a negative voltage value, the power supply will assert a signal on Pin 4

of the user signal line. You can use the user signal to trip external relays to switch

the output polarity.

Range: 0 to model maximum output voltage (VMAX)

Initial value: 0 volts

VSET?

Asks for the power supply’s present output voltage setting. Does not apply to

voltage settings which are being held. See HOLD command.

Accumulated Status, Status, and Fault Registers

The Ethernet/RS-232 Interface card uses three separate registers which

are always active. They are the accumulated status, status, and fault

registers. You can use the status commands shown in Table 3-6, “Status

Commands” on page 3–8 to activate the registers. The bit register has

twelve conditions, each assigned a bit weight. When querying a register,

the controller returns a response which is the sum of the weights of all

relevant conditions.

Example:

ASTS?

Query the Accumulated Status register.

Controller response.

ASTS 771

771 = 512 + 256 + 2 + 1 = PON + REM + CC + CV

The accumulated status register shows that PON, REM, CC and CV have

all been active since the last accumulated status register query.

Table 3-8 shows the mnemonics and bit weights which correspond to each

fault and status register by using the MASK and UNMASK commands.

WARNING

Exercise caution when using and servicing power supplies.

High energy levels can be stored at the output voltage terminals

on all power supplies in normal operation. In addition,

potentially lethal voltages exist in the power circuit and the

output connector of power supplies which are rated at 40V and

over. Filter capacitors store potentially dangerous energy for

some time after power is removed.

Diagnostic LEDs

This section describes the diagnostic LEDs found on the Ethernet/RS-232

Interface.

Computer Operating Properly (COP) LEDs

The Ethernet/RS-232 Interface provides three diagnostic LEDs, located at

CR167, CR166, and CR89 on its PCB. Refer to Figure 2-3, “Ethernet/RS-

232 Interface PCB” on page 2–6, for their locations. At present, these

LEDs turn on to signal COP events for the interface's microprocessors.

Issue a RST (reset) command to turn off the diagnostic LEDs.

The green COP LED at circuit designation CR167 indicates that the

Ethernet/RS-232 Interface microprocessor successfully recovered from a

timeout error due to a communications bus error. The event is transparent

to the RS-232 communications line which continues to function normally.

The red COP LED at CR166 indicates that a transparent restart caused by

noise in the master processor circuitry has occurred.

The red COP LED at CR89 indicates that a transparent restart caused by

noise in the slave processor circuitry has occurred.

Introduction

WARNING

Exercise caution when using and servicing power supplies.

High energy levels can be stored at the output voltage terminals

on all power supplies in normal operation. In addition,

potentially lethal voltages exist in the power circuit and the

output connector of power supplies which are rated at 40V and

over. Filter capacitors store potentially dangerous energy for

some time after power is removed.

You can calibrate the interface in either Ethernet or RS-232 mode by

adjusting the signal levels on the interface card so that they correspond

to the expected signal levels on the power supply's main assembly. You

may need to recalibrate the interface if you replace parts either on the

interface board or on the main power supply board, or if the unit falls

out of specification due to component aging drifts.

Calibration

You can calibrate the Ethernet/RS-232 Interface for:

•

Voltage program

The following equipment will be required to accurately calibrate your

unit:

•

Digital Voltmeter, 5 1/2 digit, 0.1% accuracy or better, with test leads

Current sensing shunt resistor, rated for 150% of maximum output

current, 0.25% accuracy or better

•

Connection wires rated for the unit's maximum output current and

voltage

We recommend that you perform OVP calibration every six months.

Connecting a digital voltmeter as in “Voltage Calibration Setup” is

optional.

1. Disconnect all loads from the power supply.

2. Ensure that jumper J65 on the interface PCB is CLOSED to enable

remote OVP calibration (Jumper J65 is closed at the factory). See

Figure 2-3, “Ethernet/RS-232 Interface PCB” on page 2–6 for the

location on the PCB of jumper J65.

3. Activate calibration mode by sending command CMODE ON or

CMODE 1 to the power supply.

4. Send the command OVCAL to the power supply. The ADDR LED

will light during OVP calibration. Calibration is complete when the

ADDR LED turns off. This may take a few minutes.

5. Use the OVSET, OVSET?, and VSET commands to trip the OVP

level, confirming that the calibration was successful. When you trip

the OVP level, the red OVP LED will light and the voltage will drop

to zero. Send the command RST to clear the OVP condition. Refer to

the OVP program accuracy specification in Appendix A.
