-515-000Rev.

3.9 CONNECTING THE LOAD

3.9.1

Load Wiring

e following considerations should be made to select wiring for connecting the load to the power

supply:Current carrying capacity of the wire (refer to Section 3.9.2)



Insulation rating of the wire should be at least equivalent to the maximum output volta

ge of the

power supply.



Maximum wire length and voltage drop (refer to Section 3.9.2)



Noise and impedance effects of the load wiring (refer to Section 3.9.4).

3.9.2

Current Carrying Capacity

Two factors must be considered when selecting the wire size:

Wires shou

ld be at least heavy enough not to overheat while carrying the power supply load

current at the rated load, or the current that would flow in the event the load wires were

shorted, whic

ever is greater.

Wire size should be selected to enable voltage drop p

er lead to be less than 1.0V at the rated

current. Although units will compensate for up to 5V in each load wire, it is recommended to

minimize the voltage drop (1V typical maximum) to prevent excessive output power consum

tion from the power supply and po

or dynamic response to load changes. Please refer to T

For currents not shown in Table 3

3, use the formula:

Maximum length=1000/(current x resistivity)

Where current is expressed in Amperes and resistivity in ohms/km or ohms/1000ft.

3.9.3

Wire termination

The wires should be properly termi

nated with terminals securely attached. DO NOT use unterm

nated

wires for load connection at the power supply.

3.9.4

Noise and Impedance Effects

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted

pairs to th

e shortest possible length. Shielding of sense leads may be necessary in high noise env

ronments. Where shielding is used, connect the shield to the chassis via a rear panel Ground screw.

Even if noise is not a concern, the load and remote sense wires shou

ld be twisted

pairs to reduce

coupling, which might impact the stability of power supply. The sense leads should be separated from

the power leads.

Twisting the load wires reduces the parasitic inductance of the cable, which could produce high fr

quency v

oltage spikes at the load and the output of the power supply, because of current variation in

the load itself.

The impedance introduced between the power supply output and the load could make the ripple and

noise at the load worse than the noise at the pow

er supply rear panel output. Additional filtering with

bypass capacitors at the load term

nals may be required to bypass the high frequency load current.

3.9.5

Inductive loads

Inductive loads can produce voltage spikes that may be harmful to the power supply. A diode should

be connected across the output. The diode voltage and current rating shou

ld be greater than the

power supply maximum output voltage and cu

rent rating. Connect the cathode to the positive output

and the anode to the negative output of the power supply.

Where positive load transients such as back EMF from a motor may occur, conn

ect a surge suppre

sor across the output to protect the power supply. The breakdown voltage rating of the suppressor

must be approximately 10% higher than the max

mum output voltage of the power supply.

parts. Ensure that the load wiring insulation rating is greater than or

equal to the maximum output voltage of the power supply.

CAUTION

Ensure that the load wiring mounting hardware does not short the ou

put

terminals. Heavy connec

ting cables must have some form of strain relief

to prevent loosening the connections or bending the bus

bars.

3.9.7

Connecting single loads, local sensing (default).

Fig.3

11 shows recommended load and sensing connections for a single load. The local sense lines

shown are default connections at th

e rear panel J2 sense connector. Local sensing is suitable for a

plications where load regulation is less crit

cal.

3.9.8

Connecting single loads, remote sensing

Fig.3

12 shows recommended remote sensing connection for single loads. Remote sensing is used

whe

n, in Constant Voltage mode, the load regul

tion is important at the load terminals. Use twisted or

shielded wires to minimize noise pick

up. If shielded wires are used, the shield should be co

nected

to the ground at one point, either at the power supply

chassis or the load ground. The optimal point

for the shield ground should be determined by e

perimentation.

3.9.9

Connecting multiple loads, radial distribution method

Fig.3

13 shows multiple loads connected to one supply. Each load should be connected to th

e power

supply’s output terminals using separate

airs of wires. It is recommended that each pair of wires will

be as short as possible and twisted or shielded to minimize noise pick

up and radiation. The sense

wires should be connected to the power supply

output terminals or to the load with the most critical

load reg

lation requirement.

Multiple load connection with distribution terminals

If remotely located output distribution terminals are used, the power supply output terminals should be

connected to the distribution term

nals by pair of twisted and/or shielded wires. Each load should be

separately connected to the remote distribution terminals (see Fig.3

14).

If remote sensing is required, the sensing wires should be connected to the dis

tribution terminals or at

the most critical load.

3.9.11

Grounding outputs

Either the positive or negative output terminals can be grounded. To avoid noise prob

ems caused by

common

mode current flowing from the load to ground, it is recommended to ground the

output

terminal as close as possible to the power supply chassis ground.

Always use two wires to connect the load to the power supply regardless of how the system is

grounded.

-515-000Rev.

3.10.3

Remote sensing

Use remote sense where the load regulation at the load end is critical. In remote sense,

the power

supply will compensate for voltage drop on the load wires. Refer to the power supply specific

tions for

the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage avai

able at the output. Follow the instructions

below to configure the power supply for remote sensing:

Ensure that the AC On/Off is in the Off position.

Remove the local sense jumpers from J2.

Connect the negative sense lead to terminal J2

5 (-S) and the positive sense lead to term

nal J2

1(+S) of the

J2 mating connector. Ensure that the J2 mating connector is plugged securely into

the rear panel sense connector, J2.

Turn On the power supply.

Notes:

If the power supply is operating in remote sense and either the positive or negative load wire is not

nnected, an internal protection circuit will activate and shut down the power supply. To resume

operation, turn the AC On/Off to the Off position, connect the open load wire, and turn On the

power supply.

If the power supply is operated without the remote

sense lines or local sense jumpers, it will co

tinue to work, but the output voltage regulation will be degraded. Also, the OVP circuit may act

vate and shut down the power supply.

5.2 STANDARD OPERATION

The power supply has two basic operating modes: Constant Voltage Mode and Constant Current

Mode. The mode in which the power supply operates at any given time depends on the Output Vol

age setting, O

utput Current setting and the load resistance.

5.2.1 Constant Voltage Mode

In constant voltage mode, the power supply regulates the Output Voltage at the selected value,

while the load current varies as required by the load.

While the power supply operate

s in constant voltage mode, the VOLTAGE LED on the front panel

illuminates.

Adjustment of the Output Voltage can be made when the power supply output is enabled (Output

On) or disabled (Output Off). When the output is enabled, simply rotate the VOLTAGE enc

oder

knob to program the output voltage. When the output is disabled, press the PREV button and

then rotate the VOLTAGE encoder knob. The VOLTAGE meter will show the programmed Output

Voltage for 5 seconds after the adjustment has been completed. Then the

VOLTAGE meter will

display “OFF”.

Adjustment resolution can be set to coarse or fine resolution. Press FINE button to select b

tween

the lower and higher resolution. The FINE LED turns On when the resolution is set to FINE.

5.2.2 Constant Curre

nt Mode

In constant current mode, the power supply regulates the Output Current at the selected value,

while the voltage varies with the load requirement.

While the power supply is operating in constant current mode, the CURRENT LED on the front

panel illu

minates.

Adjustment of the Output Current setting can be made when the power supply output is enabled

(Output On) or disabled (Output Off).

Disabled output (Off): Press PREV button and then rotate the Current encoder knob. The

CURRENT meter will show the

programmed Output Current limit for 5 seconds after the adjus

ment has been completed. Then the VOLTAGE meter will display “OFF”.

NOTE

If after completing the adjustment,

the display shows a different value

than the setting, the power supply may be at current limit. Check the

load condition and the power supply Output Current setting.

NOTE

The maximum and minimum setting v

alues of the output voltage are

limited by the Over Voltage protection and Under Voltage limit se

ting.

Refer to Sections 5.3 and 5.4 for more details.

-515-000Rev.

Enabled output, power supply in Constant Voltage mode: Press the PREV button and then r

tate the CURRENT encoder knob. The C

URRENT meter will show the programmed Output

Current for 5 seconds after the adjustment has been completed, and then will return to show

the a

tual load current.

Enabled output, power supply in Constant Current mode: Rotate the CURRENT encoder

knob to adj

ust the Output Current.

Adjustment resolution can be set to Coarse or Fine adjustment. Press the FINE button to select

between the Coarse and Fine resolution. The FINE LED turns On when the resolution is set to

FINE.

5.2.3 Automatic Crossover

If the power

supply operates in Constant Voltage mode, while the load current is increased to greater

than the current limit setting, the power supply will automatically switch to Constant Cu

rent mode. If

the load is decreased to less than the current limit setting, t

he power supply will automatically switch

back to Constant Voltage mode.

5.3

OVER VOLTAGE PROTECTION (OVP)

The OVP circuit protects the load in the event of a remote or local programming error or a power su

ply failure. The protection circuit monitors the volt

age at the power supply sense points and thus pr

vides the protection level at the load. Upon detection of an Over Voltage condition, the power supply

output will shut down.

5.3.1

Setting the OVP level

The OVP can be set when the power supply output is Enabled (

On) or Disabled (Off). To set the OVP

level, press the OVP/UVL button, so that the CURRENT meter shows “OUP”. The VOLTAGE meter

shows the OVP setting level. Rotate the VOLTAGE encoder knob to adjust the OVP level. The display

will show “OUP” and the settin

g value for 5 seconds after the adjustment has been co

pleted, and

then will return to its previous state.

The minimum setting level is approximately 105% of the

set Output Voltage, or the value in Table 7

6, whichever is

higher. The maximum setting level is shown in Table 5

-1.To preview the OVP setting, press the OVP/UVL pushbu

ton so that the CU

RRENT display will show “OUP”. At this

time, the VOLTAGE display will show the OVP setting. A

ter 5 seconds, the display will return to its previous state.

Table 5

1: Maximum OVP s

etting levels

5.3.2

Activated OVP protection indications

When the OVP is activated the power supply output shuts down. The VOLTAGE display shows “OUP”

and the ALARM LED blinks.

5.3.3

Resetting the OVP circuit

To reset the OVP circuit after it activates:

Reduce the pow

er supply Output Voltage setting below the OVP set level.

Ensure that the load and the sense wiring are connected properly.

There are four methods to reset the OVP circuit.

3.1

Press the OUT button.

3.2

Turn the power supply Off using the AC On/Off switc

h, wait until the front panel display

turns Off, then turn the power supply On using the AC On/Off switch.

3.3

Turn the power supply output Off and then On using the SO control (refer to Section 5.7).

In this method the power supply should be set to Auto

Restart mode.

5.4AUNDER VOLTAGE LIMIT (UVL)

The UVL prevents adjustment of the Output Vol

age below a certain limit. The combination of UVL

and OVP functions, allow the user to create a protec

tion window for sensitive load circuitry.

5.4.1

Setting the UVL level

Setting the UVL can be made when the power supply output is Enabled (On) or Disabled (Off). To set

the UVL level, press the OVP/UVL button TWICE, so that the CURRENT meter shows “UUL”. The

VOL

TAGE meter shows the UVL setting level. Rotate the VOLTAGE encoder knob to adjust the UVL

level. The display will show ‘UUL” and the setting value for 5 seconds after the adjustment has been

completed and then will return to its previous state.

UVL setting

values are limited at the maximum level to approximately 95% of the Output Voltage se

ting. Attempting to adjust the UVL above this limit will result in no response to the adjustment attempt.

The minimum UVL se

ting is zero.

5.5

FOLDBACK PROTECTION

Foldback

protection will shut down the power supply output if the load current exceeds the current

limit setting level. This protection is useful when the load circuitry is sensitive to an overcurrent cond

tion.

5.5.1

Setting the Foldback protection

To arm the Foldback p

rotection, the FOLD button should be pressed so that the FOLD LED illum

nates. In this condition, transition from Constant Voltage to Constant Current mode will activate the

Foldback protection. Activation of the Foldback protection disables the power supp

ly output, causes

the ALARM LED to blink and displays “Fb” on the VOLTAGE meter.

5.5.2

Resetting activated Foldback protection

There are four methods to reset an activated Foldback protection.

Press the OUT button. The power supply output is enabled and the Out

put Voltage and Cu

rent

will return to their last setting. In this method, the Foldback protection remains armed, therefore if

the load current is higher than the current limit setting, the Foldback protection will be activated

again.

Press the FOLD button

to cancel the Foldback protection. The power supply output will be di

abled and the VOLTAGE display will show “OFF”. Press the OUT button to enable the power su

ply output.

Turn the power supply output Off and then On using the SO control (refer to Sectio

n 5.7). In this

method the Foldback protection remains armed, therefore if the load current is higher than the

output current setting, the Foldback prote

tion will be activated.

Turn the power supply Off using the AC On/Off switch, wait until the front pan

el display turns Off,

then turn the unit back ON again. The power supply output is enabled and the Output Voltage and

Current will return to their last setting. In this method, the Foldback protection remains armed,

therefore if the load current is higher

than the output current setting, the Foldback protection will

be activated again.

5.6

OUTPUT ON/OFF CONTROL

The Output On/Off Enables or Disables the power supply output. Use this function to make adjus

ments to either the power supply or the load without shu

tting off the AC power. The Output On/Off

can be activated from the front panel using the OUT button or from the rear panel J1 connector. The

OUT button can be pressed at any time to Enable or Disable the power supply output. When the ou

put is disabled, t

he Output Voltage and Current fall to zero and the VOLTAGE display shows “OFF”.

5.7

OUTPUT SHUT

OFF (SO) CONTROL VIA REAR PANEL J1 CONNECTOR

Contacts 2, 3 and 15 of J1 (Fig.4

2, Item 5) serve as Output Shut

Off (SO) terminals. The SO term

nals accept a 2.5V t

o 15V signal or Open

Short contact to disable or enable the power supply output.

The SO function will be activated only when a transition from On to Off is detected after applying AC

power to the unit. (Thus, in Auto

Restart mode, the output will be Enable

d after applying AC power;

even if SO is at an Off level). After an On to Off trans

tion it is detected, the SO will Enable or Disable

the power supply output according to the signal level or the short/open applied to J1. This function is

-515-000Rev.

useful for connec

ting power supplies in a “Daisy

chain” (refer to Section 5.16). The SO control can

also be used to reset the OVP and Fold Protection (refer to Section 5.3 and 5.5 for details).

When the unit is shut

off by a J1 signal, the VOLTAGE display will show “SO” to

indicate the unit

state. J1 contact 15 is the SO signal input and contacts 2 and 3, IF_COM, are the signal return (co

nected internally). Co

tacts 2, 3 and 15 are optically isolated from the power supply output.

The SO control logic can be selected by the

5.15 PARALLEL OPERATION

Up to four units of the same VOLTAGE and CURRENT rating can be connected in parallel to provide

up to four times the Output Current capability. One of the units operates as a Master and the remai

ing

units are Slaves. The Slave units are analog programmed by the Master unit. In remote digital o

eration, only the Master unit can be programmed by the computer, while the Slave units may be co

nected to the computer for voltage, current and status readbac

k only. Follow the following procedure

to configure multiple supplies for parallel operation. Refer to Sec. 5.15

and to Sec. 5.15.2 for d

tailed explanation.

5.15.1

Basic parallel operation

In this method, setting the units as Master and Slaves is made by the r

ear panel J1 connections and

the setup switch SW1. Each unit displays its own output current and voltage. To program the load cu

rent, the Master unit should be programmed to the total load current divided by the number of units in

the system. Refer to the

following procedure to configure multiple supplies for

basic

parallel operation.

1. Setting up the Master unit

Set the Master unit Output Voltage to the desired voltage. Program the Output Current to the d

sired

load current divided by the number of paral

lel units. During operation, the Master unit ope

ates in CV

mode, regulating the load voltage at the programmed Output Voltage. Connect the sensing circuit to

local or remote sensing as shown in Fig.5

4 or fig.5

Setting up the Slave units

-1.The Out

put Voltage of the Slave units should be programmed 2

5% higher than the Output

Voltage of the Master unit to prevent interference with the Master unit’s control. The Output Cu

rent setting of each unit should be programmed to the desired load current div

ided by the number

of parallel units.

2. Set the rear panel setup switch SW1 position 2 to the up position.

3. Connect a wire jumper between J1

8 and J1

12 (refer to Table 4

4).-4. Connect J1 terminal 10(IPGM) of the slave unit to J1 terminal 25(P) of t

he master unit.

5. Connect J1 terminal 23(IPGM_RTN) of the slave unit to J1 terminal 12 (COM) of the master unit.

During operation, the Slave units operate as a controlled current source following the Master Ou

put

Current. It is recommended that the powe

r system be designed so that each unit supplies up to 95%

of its current rating because of the imbalance which may be caused by cabling and connection vol

age drop.

Daisy Chain Connection: (See Fig. 5.6)

These set up and connections are optional but is str

ongly recommended. It will shut down all

power supplies when a fault condition occurs in any one of them.

Setting Over Voltage protection

The Master unit OVP setting should be programmed to the desired OVP level. The OVP setting of

the slave units should be programmed to a highe

r value than the Master OVP. When the Master

unit shuts down, it programs the Slave unit to zero Output Voltage. If a Slave unit shuts down

(when its OVP is set lower than the Master Output Voltage

and, if all P/S are not daisy chained

per section 3 above

)

, only that Slave unit would shut down, and the remaining Slave units would

supply all the load cu

rent.

Setting Foldback protection

Foldback protection, is desired, may only be used with the Master unit. When the Master unit

shuts down, it programs the Sl

ave units to zero Output Vol

age.

CHAPTER 6 REMOTE ANALOG PROGRAMMING

6.1 INTRODUCTION

The rear panel connector J1 allows the user to program the power supply Output Voltag

e and Cu

rent

with an analog device. J1 also provides monitoring signals for Output Voltage and Output Current.

The pr

gramming range and monitoring signals range can be selected between 0

5V or 0

10V using

the setup switch SW1. When the power supply is

in Remote Analog programming, the serial comm

nication port is a

tive and can be used to read the power supply parameters.

6.2 LOCAL/REMOTE AN

ALOG

CONTROL

ontact 8 of J1 (Fig.4

2, Item 5) accepts TTL signal or Open

Short contact (referenced to J1

12) to

select between Local or Remote Analog programming of the Output Voltage and Current.

In Local mode, the Output Voltage and Output Current can be programmed via the front panel

VOLTAGE and CURRENT encoders or via the RS232/RS485 port. In Remote Analo

g mode, the Ou

put Voltage and current can be programmed by analog voltage or by programming resistors via J1

contacts 9 and 10 (refer to Sections 6.4 and 6.5). Refer to Table 6

MD MODE OPTION (Factory Installed)

.4.1MD Mode Description

The GEN supply is capable of operating in a multi drop environment

more than 1 supply co

ducting

serial communications on a single serial bus. A maximum of 31 GEN suppli

es can operate in this si

gle bus. Upon power up the Gen will enter the point

-to-

point mode in which it is assumed that only 1

supply will operate on a serial bus. MD Mode must be enabled

Ref. Section 7.10.2.2. The user must

set all Slave supplies to a u

nique address. No two supplies may have the same address.

4.2

MD Mode enable

–

Serial comm

nication mode

Refer to section 7.10.2.2. MD Mode is entered into via a Single byte command. In MD Mode the Ma

ter supply shall operate in one of the two serial mo

des, RS232 or RS485, depending upon the rear

panel DIP switch setting and the Slave supplies shall operate in the RS485 s

rial mode.

7.4.3

MD Mode SRQ

In MD Mode the SRQ generated by the supply is replaced by a single byte SRQ sent two times in s

quence.

The SRQ byte, in binary, will contain the address of the supply in the least significant 5 bits

with bits 5 and 6 set to logic zero and bit 7 set to logic 1. Ref. Table 7

7.4.4

Communication Collisions

In MD Mode it is possible to have one supply issue

an SRQ while another supply is transmitting

data/response to a command. When this happens, the HOST PC will receive garbled data and a

sume that the data/response was corrupted and thus re

send the command

the SRQ will probably

be lost. The method of re

covery will be SRQ retransmission, Ref. Section 7.4.5, or polling all a

tached

supplies to see who issued the SRQ

available by reading the SEVE? Register.

7.4.5

MD Mode SRQ Retransmission

The supply can be commanded to retransmit the SRQ at regular inte

vals until it is answered to by the

HOST PC (Ref. Section 7.10.2.4). The retransmission interval is 10 ms plus the supply address mult

plied by 20 ms.

7.10

SINGLE BYTE COMMANDS

7.10.1

General

Single byte commands are commands in which all the necessary data for the supply to act upon is

contained in a single byte. Single byte commands will be executed immed

ately by the supply. If the

command require

s data to be sent to the HOST PC or IEEE Board (see se

tions 7.10.4 and 7.10.3.1)

that response will be transmitted immediately with no delay due to any software overhead. With the

exception of the Disconnect from communications command, section 7.10.3.1,

commands must be

sent by the HOST PC or IEEE Board 2 times in s

quence for verification. All

have the most significant

bit, D7, set to a logic 1. A CR, carriage r

turn, character is not included in a single byte command.

The RST command will not change any

setting made by a single byte command.

All Single Byte commands will be executed in 1 ms or less. This does not include any r

sponse sent

to the HOST/IEEE Board, which is dependent upon the response length and the serial transmission

speed (Baud rate).

10.2

Global commands without response

7.10.2.1

Disable MD Mode (MD MODE OPTION REQUIRED)

Disable is the default condition upon power up. The Hex value of the command is 0xA0. Send it two

times in sequence. All supplies, both the currently addressed suppl

y and all non

addressed su

plies,

will disable MD Mode as a result of this command.

7.10.2.2

Enable MD Mode (MD MODE OPTION REQUIRED)

Send to enable Multi Drop Mode. The Hex va

lue of the command is 0xA1. Send

it two times in s

quence. When this command is

sent, the supply will set SRQ retransmission to the disable state; if

you wish it to be enabled you must send the enable command. All supplies, both the currently a

dressed supply and all non

addressed supplies, will enable MD Mode as a result of this com

mand.

7.10.2.3

Disable SRQ retransmission (MD MODE OPTION REQUIRED)

Disable is the default condition upon power up. The Hex va

lue of the command is 0xA2. Send

it two

times in sequence. If the supply sends an SRQ it will only sent it 1 time. All supplies,

both the cu

rently addressed supply and all non

addressed supplies, will disable SRQ retransmission as a result

of this command. All status registers will retain their data when this command is sent.

7.10.2.4

Enable SRQ retransmission (MD MODE OPTION REQU

IRED)

Enable retransmission of SRQs. This is only available when the Multi Drop Mode is enabled in the

supply. The Hex value of the command is 0xA3. Send it two times in s

quence. If the supply sends an

SRQ it will be repeated on a timely basis, 10 ms plus

20 ms times the supply address, until answered.

All supplies, both the currently addressed supply and all non

addressed supplies, will enable SRQ r

transmission as a result of this co

mand.

7.10.2.5

Enable FLT Bit in the SENA Register

The Hex value of th

e command is 0xA4. Send it two times in sequence.

7.10.3

Global commands with response

7.10.3.1

Disconnect from communications

Command the supply to end all data transmissions to the HOST PC/IEEE Board and cease its role as

the active addressed supply.

The HOST PC/IEEE Board will be required to re

send the ‘ADR nn’

command to reestablish communications with the supply. After r

ceiving the first command the supply

will respond with an OK<CR>. The Hex value of the co

mand is 0xBF. All supplies, both the cu

rrently

-515-000Rev.

addressed supply and all non

addressed supplies, will respond to this command; but only the cu

rently a

dressed supply (if any) will respond with the ‘OK’.

7.10.4

Addressed commands with response

7.10.4.1

Read registers

Send (0x80 + Address) (1 b

yte binary

send 2 times sequentially). The supply will return the contents

of the Status Condition Register, the Status Enable Register, the Status Event Register (SEVE?), the

Fault Condition Register, the Fault Enable Register and the Fault Event Regist

er IFEVE/). All registers

will be represented in two Hex bytes. Following the register data, a single dollar sign, $, will be added

to signal the end of data and the start of a checksum. The checksum will be the sum of all register

data and will be represe

nted in two Hex bytes. The transmission will end with the CR character. If r

petitive sending of SRQs was active and the supply was sending them, the supply will stop sen

ing

repetitive SRQs but leave the function active. The contents of the registers will

not be destro

yed. Note

that the supply does

not have to be the active addressed su

ply.

Note that this command will not execute if another command is being processed.

7.10.4.2

Print Power On Time

Print the total time the supply has operated under AC pow

er. Send 2 bytes in sequence, A6 Hex and

the address of the supply in binary. A 32 bit integer will be returned in 8 Hex bytes. The data will be

the number of minutes that power has been ‘ON’ in the supply in binary. A ‘$’ sign and 2 byte Hex

checksum will

be appended to the data. There is no method provided to reset this number.

Retransmit last message.

Send (0xC0 + Address) (1 byte binary

send 2 times sequentially). The supply will return the last

message sent. Note that the supply does not have to be t

he active addressed su

ply.

This command will not execute if another command is being processed.

Note that Single byte commands do not load data into the supply’s data output buffer.

Thus this command will not cause the supply to retransmit data obtained f

rom any prev

ous Single

Byte Command.

7.10.4.3

Retransmit Last Message

Send (0xC0 + Address) (1 byte binary

send 2 times sequentially). The supply will return the last

message sent. Note that the supply does not have to be the active addressed su

ply.

This command will not execute if another command is being processed.

Note that Single byte commands do not load data into the supply’s data output buffer. Thus this

command will not cause the supply to retransmit data obtained from any previous Single Byte

Com-mand.

7.10.4.4

Test if MD Mode is Installed

Send AA Hex followed by the address of the supply in binary. If not installed, the supply will return a

‘1’. If installed, the supply will return a ‘0’.

7.10.5

Addressed commands without response

7.10.5.1

Acknowledge SRQ

Send (0xE0 + Address) (1 byte binary

send 2 times sequentially).

The supply will stop re

sending

SRQ.

If Enable SRQ retransmission is active, it will remain active.

7.10.5.2

Re-enable SRQ with out reading/clearing the SEVE Register

Send

A5 Hex followed by the address of the supply in binary and new SRQ’s generated by new

events in the Fault Event will be enabled without reading and clearing the Status Event Register. All

events previously recorded in the Fault Event Register must have be

en serviced by the user’s sof

ware prior to this command to take affect.

CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION

8.1 INTRODUCTION

Isolated Analog Programming

is an internal Option Card for analog programming of the Genesys

power supply series. The option is factory installed and cannot be obtained with a GPIB (IEEE

488)

Interface. Output Voltage and Output Current can be programmed and readback through optica

lly is

lated si

nals which are isolated from all other ground references in the power supply.

There are two types of Isolated Analog programming cards:

1.0-

5V/0

10V option (PN: IS510): Using 0

5V or 0

10V signals for programming and readback.

2.4-

20mA option (

PN: IS420): Using current signals for programming and readback.
