COPPER WIRE SIZE

Table 3-2: Recommended Cable Size for Output Connection

3.9.1. Wire Termination

The wires should be properly terminated with terminals securely attached. DO NOT use un-terminated wires for load connection at the power supply.

CAUTION

Be careful when connecting the remote sense lines to the far end of the load

cables. Reversing the sense line polarity to the load, or leaving the +S or –S

sense lines opened, could damage the power supply.

See Section 3.10.3 for more information.

83-530-000 Rev J

3.9.2. Noise and Impedance Effects

Supply

Load

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted pairs to the shortest possible length. Shielding of sense leads may be necessary in high noise environments. 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 should 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 frequency voltage spikes at the load and the output of 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 power supply rear panel output. Additional filtering with bypass capacitors at the load terminals may be required to bypass the high frequency load current.

3.9.3. 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 should be greater than the power supply maximum output voltage and current 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, connect a surge suppressor across the output to protect the power supply. The breakdown voltage rating of the suppressor must be approximately 10% higher than the maximum output voltage of the power supply.

3.9.4. Connecting Single Loads, Local Sensing (Default).

Fig.3-10 shows recommended load and sensing connections for a single load. The local sense lines shown are default connections at the rear panel J2 sense connector. Local sensing is suitable for applications where load regulation is less critical.

The optimal point for the shield ground should be determined by experimentation.

If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-6).

If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.

There is a potential shock hazard at the sense connector when using

a power supply with a rated output voltage greater than 40V. Local

sense and remote sense wires should have a minimum insulation

rating equivalent or greater than the maximum output voltage of the

power supply. Ensure that the connections at the load end are

shielded to prevent accidental contact with hazardous voltages.

3.9.7. Grounding Outputs

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

3.10. Local and Remote Sensing

The rear panel J2 sense connector is used to configure the power supply for local or remote sensing of the output voltage. Refer to Fig.3-7 for sense connector location.

3.10.1. Sense Wiring

3.10.2. Local Sensing

The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the output voltage. See Table 3-4 for J2 terminals assignment. With local sensing, the output voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regulation is less critical.

power supply with a rated output voltage greater than 40V. Ensure

When using shielded sense wires, ground the shield in one place only. The

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 specifications for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage available at the output. Follow the instructions below to configure the power supply for remote sensing:

a) Ensure that the AC On/Off is in the Off position. b) Remove the local sense jumpers from J2. c) Connect the negative sense lead to terminal J2-5 (S) and the positive sense lead to

terminal J2-1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely into the rear panel sense connector, J2.

d) Turn On the power supply.

WARNING

There is a potential shock hazard at the sense point when using

that the connections at the load end are shielded to prevent

accidental contact with hazardous voltages.

CAUTION

NOTES:

1. If the power supply is operating in remote sense and either the positive or negative load wire is not connected, an internal protection circuit will activate and shut down the power supply. To resume operation, turn to the Off position, connect the open load wire, and turn On the power supply.

2. If the power supply is operated without the remote sense lines or local sense jumpers, it will continue to work, but the output voltage regulation will be degraded. Also, the OVP circuit may activate and shut down the power supply.

5. LOCAL OPERATION

5.1. Introduction

This Chapter describes the operating modes that are not involved in programming and monitoring the power supply via its serial communication port (RS232/RS485) or by remote analog signals. Ensure that the REM/LOC LED on the front panel is Off, indicating Local mode. If the REM/LOC LED is On, press the front panel REM/LOC button to change the operating mode to local.

 For information regarding remote analog programming refer to Chapter 7.  For information regarding usage of the serial communication port refer to Chapter 8.

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 voltage setting, output current limit setting and the load resistance.

5.2.1. Constant Voltage Mode

a) 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.

b) While the power supply operates in constant voltage mode, the VOLTAGE LED on

the front panel illuminates.

c) 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 encoder 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”.

d) Adjustment resolution can be set to coarse or fine resolution. Press FINE button to

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

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 maximum and minimum setting values of the output voltage are limited by

the Over Voltage protection and Under Voltage limit setting. Refer to Sections

NOTE

the power supply current limit setting.

NOTE

5.3 and 5.4 for more details.

83-530-000 Rev J

5.2.2. Constant Current Operation

a) In constant current mode, the power supply regulates the output current at the

selected value, while the voltage varies with the load requirement.

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

the front panel illuminates.

c) Adjustment of the output current 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 current for 5 seconds after the adjustment has been completed. Then the VOLTAGE meter will display “OFF”.

 Enabled output, power supply in Constant Voltage mode: Press the PREV button

and then rotate the CURRENT encoder knob. The CURRENT meter will show the programmed current limit for 5 seconds after the adjustment has been completed, and then will return to show the actual load current.

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

encoder knob to adjust the current limit.

d) 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 Current mode. If the load is decreased to less than the current limit setting, the 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 supply failure. The protection circuit monitors the voltage at the power supply sense points and thus providing 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 setting value for 5 seconds after the adjustment has been completed and then will return to its previous state.

To preview the OVP setting, press the OVP/UVL pushbutton so that the CURRENT display will show “OUP”. At this time, the VOLTAGE display will show the OVP setting. After 5 seconds, the display will return to its previous state.

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.

83-530-000 Rev J

5.3.3. Resetting the OVP Circuit

To reset the OVP circuit after it activates: a) Reduce the power supply Output Voltage setting below the OVP set level.

b) Ensure that the load and the sense wiring are connected properly. c) There are four methods to reset the OVP circuit.

 Press OUT button.  Turn the power supply Off using the AC On/Off switch, wait until the front panel

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

 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.

 Send OUT command via the RS232/485 communication port.

5.4. Under Voltage Limit (UVL)

The UVL prevents adjustment of the output voltage below a certain limit. The combination of UVL and OVP functions, allow the user to create a protection 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 VOLTAGE 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 5% below the Output Voltage setting. Attempting to adjust the UVL above this limit will result in no response to the adjustment attempt. The minimum UVL setting 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 over current condition.

5.5.1. Setting the Foldback Protection

To arm the Foldback protection, the FOLD button should be pressed so that the FOLD LED illuminates. In this condition, transition fromConstant Voltage to Constant Current mode will activate the Foldback protection. Activation of the Foldback protection disables the power supply output, causes the ALARM LED to blink and displays “Fb” on the VOLTAGE meter.

83-530-000 Rev J

5.5.2. Resetting Activated Foldback Protection

There are four methods to reset an activated Foldback protection. a) Press the OUT button. 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 current limit setting, the Foldback protection will be activated again.

b) Press the FOLD button to cancel the Foldback protection. The power supply output

will be disabled and the VOLTAGE display will show “OFF”. Press the OUT button to enable the power supply output.

c) Turn the power supply output Off and then On using the SO control (Refer to Section

5.7). 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.

d) Turn the power supply Off using the switch, wait until the front panel 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 current limit 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 adjustments to either the power supply or the load without shutting off the ON/OFF switch. 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 output is disabled, the 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 terminals accept a 2.5V to 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 unit. (Thus, in Auto-Restart mode, the output will be enabled after applying AC power; even if SO is in Off level). After On to Off transition 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 useful for connecting power supplies in a “Daisy-chain” (refer to Section 6.3). The SO control can be used also to reset the OVP and Fold Protection. refer to Section 5.3 and 5.5 for details.

When the unit is shut-off by 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 (connected internally). Contacts 2, 3 and 15 are optically isolated from the power supply output.

The SO control logic can be selected by the rear panel SW1 Setup switch. Refer to Table 5-1 for SW1 setting and SO control logic.

5.9. CV/CC Signal

CV/CC signal indicates the operating mode of the power supply, Constant Voltage or Constant Current. CV/CC signal is an open collector output with a 30V parallel zener, at J113, referenced to the COM potential at J1-12 (connected internally to the negative sense potential). When the power supply operates in Constant Voltage mode, CV/CC output is open. When the power supply operates in Constant Current mode, CV/CC signal output is low (0-0.6), with maximum 10mA sink current.

5.10. PS_OK Signal

PS_OK signal indicates fault condition in the power supply. PS_OK is a TTL signal output at J1-16, referenced to IF_COM at J1-2, 3 (Isolated Interface Common). When a fault condition occurs, PS_OK level is low, with maximum sink current of 1mA; when no fault condition occurs, PS_OK level is high with maximum source current of 2mA. The following faults will set the PS_OK to Fault state:

*OTP*Enable/Disable open *OVP *SO (Rear panel Shut-Off) *Foldback *IEEE failure (With optional IEEE interface) *AC fail *Output Off

current to less than 10mA.

83-530-000 Rev J

5.11. Safe Start and Auto-Restart Modes

When turning on the power supply, it can start to its last setting of Output Voltage and Current limit with the output enabled (Auto-restart) or start with the output disabled (Safe mode). Press and hold the OUT button to select between Safe start and Auto-restart modes. The VOLTAGE display will continuously cycle between “SAF” and “AUT” every 3 seconds. Releasing OUT push-button while one of the modes is displayed, selects that mode. The default setting at shipment is Safe mode.

5.11.1. Automatic Start Mode

In this mode, the power supply restores its last operation setting. Upon start-up, the output is enabled or disabled according to its last setting.

5.11.2. Safe Start Mode

In this mode, the power supply restores its last operation setting and sets the Output to Off state. At start-up, the output is disabled and the output voltage and current are zero. To enable the output and restore the last output voltage and current limit values, momentarily press OUT button.

5.12. Front Panel Locking

The front panel controls can be locked to protect against an operator accidentally changing the power supply settings.

5.12.1. Changing the Locking

Press and hold the front panel PREView button. See the voltage display toggle between locked front panel (“LFP”) and unlocked front panel (“UFP”). Select a mode by releasing the button when the desired mode is displayed.

5.12.2. Unlocked Front Panel

5.12.3. Locked Front Panel

When the front panel is locked, the following controls are DISABLED:

 VOLTAGE and CURRENT encoders.  FOLD button.  OUT button

The power supply will not respond to attempts to use these controls. The VOLT display will show “LFP” to indicate that the front panel is locked.

Other buttons, such as PREView and OVP/UVLmay still be used to view settings.

83-530-000 Rev J

5.13. Over Temperature Protection (OTP)

The OTP circuit shuts down the power supply before the internal components can exceed their safe internal operating temperature. When an OTP shutdown occurs, the display show “OTP” and the ALARM LED blinks.

Resetting the OTP circuit can be automatic (non-latched) or manual (latched) depending on the Safe or Automatic restart mode.

a) Safe start mode: In Safe start mode, the power supply stays off after the over

temperature condition has been removed. The display continues to show “OTP” and the ALARM LED continues to blink. To reset the OTP circuit, press OUT button (or send OUT ON command via the serial port).

b) Auto-restart mode: In Auto-restart mode, the power supply recovers to its last setting

automatically when the over temperature condition is removed.

6. SERIES AND PARALLEL SUPPLIES

You may connect the outputs of Genesys™ power supplies together to produce:

▬ Voltages greater than any one supply rating (series connection). ▬ Plus and minus polarity (series connection). ▬ More current than any one supply rating (parallel connection).

In addition to connecting the outputs together, analog control connections are used to ensure the supplies are properly sharing the total voltage or current. Digital remote programming through the RS232/485, IEMD or LAN is allowed to all supplies.

When a power supply is set to remote analog control then the corresponding

voltage or current encoder, and their PREView settings, will not be affective.

Although the front panel seems like it can be used to adjust the output settings, it

is the analog control lines that actually set the programming limits.

6.1. Series Operation

Power supplies of the SAME MODEL can be connected in series to obtain increased output voltage. Split connection of the power supplies gives positive and negative output voltage.

CAUTION

NOTE

Do not connect power supplies from different manufacturers in series

or in parallel.

Use only same models for series or parallel connection.

6.1.1. Series Connection for Increased Output Voltage

In this mode, two units are connected so that their outputs are summed. Set the current limit of each power supply to the maximum that the load can handle without damage. It is recommended that diodes be connected in parallel with each unit output to prevent reverse voltage during start up sequence or in case one unit shuts down. Each diode should be rated to at least the power supply rated output voltage and output current. Refer to Fig.6-1 and 6-2 for series operation with local and remote sensing.

WARNING

When power supplies are connected in series, and the load or one of

the output terminals is grounded to chassis:

For models up to 60VDC Rated Output, no point may be at a greater

potential of +/-60VDC from ground

For models >60VDC Rated Output no point may be at a greater

potential of +/-600VDC from ground.

When using RS232/485 or IEEE, refer to the OUTPUT TERMINALS

GROUNDING warning, Safety Instructions.

6.2. Parallel Operation

Up to four units of the SAME VOLTAGE and CURRENT RATING can be connected in parallel to provide up to about four times the output current capability of one supply. One of the units operates as a master and the remaining units are slaves. The slave units are analog programmed by the master unit.

In remote digital operation (RS232/485, IEMD or LAN), only the master unit is programmed by the computer although measurements and status may be read back from the slaves.

In the simplest parallel setup, the slaves output current merely follows the master’s. A shut-off daisy chain may be added so when one supply output turns off or on, they all will. The Advanced Parallel option is a firmware setting which adds operator convenience by making the Master show the sum of all supply’s currents while the slave front panels are disabled.

6.2.1. Basic Parallel Operation

In this method, setting the units as Master and Slaves is made by the rear panel J1 connections and the setup switch SW1. Each unit displays its own output current and voltage.

Make sure that the connection between –V terminals is reliable to avoid

Disconnection may cause damage to the power supply.

CAUTION

disconnection during operation.

With local sensing it is important to minimize the wire length and resistance. Also

the positive and negative wire resistance should be close as possible to each

other to achieve current balance between power supplies.

6.2.2. Setting up the Master Unit

First understand if your load is being driven by a regulated voltage (CV mode) or a regulated current (CC mode).

 For a voltage driven load (CV): set the slaves for voltage limits that are higher

than will be reached by the master.

 For a current driven load (CC): the Master unit should be programmed to the total

load current divided by the number of units in the system. The slaves must be set to voltage limits higher than will be seen at the master.

The master may use local voltage sensing as shown in Figure 6-4. For a voltage driven load (CV), the master may use remote voltage sensing to the load as shown in Figure 6-5.

NOTE

83-530-000 Rev J

6.2.3. Setting up the Slave Units

The slaves must always run in constant current (CC) mode. This is ensured by always setting the slave’s voltage limit higher than the actual output voltage and letting the J1-10 IPGM signal regulate their current setting.

Failing to set the slave supply voltage setting high enough will cause

the slave to go into constant voltage (CV) mode. When this happens,

current will no longer be equally shared between the parallel supplies.

The following settings are used on the slave supply: a) SW1 pole 2 is UP (on rear panel). This enables remote analog current programming.

b) SW1 pole 1 is DOWN. Remote voltage programming is not allowed for a slave. c) SW1 pole 3 is DOWN. The slave current limit is a 0 to 5 volt signalfrom the master. d) Connect short between J1-8 and J1-12 (refer to Table 4-4). e) Connect J1-10 (IPGM) of the slave unit to J1-25 (P) of the master unit.

During operation the slave units operate as a controlled current source following the master output current. It is recommended that the power system is designed so that each unit supplies less than 100% of its current rating because of the imbalance which may be caused by cabling and connections voltage drop.

6.2.4. Setting Over Voltage Protection (OVP)

WARNING

The master unit OVP should be programmed to the desired OVP level. The OVP of the slave units should be programmed to a higher value than the master OVP. This prevents the slave from shutting down before the master does.

Where there is a risk from over voltages, it is recommended to use a Shut-Off daisy chain (see section TBD) so all power supplies will turn off together.

6.2.5. Setting Foldback Protection (FB)

For systems using a constant voltage (CV) regulated load, foldback protection is recommended as a protection from accidental short circuits. The foldback protection may only be set in the master supply. If the master shuts down, it programs the slave units to zero output voltage.

6.3. Daisy-Chain for Shut-Off

Fig. 6

6: Daisy

chain connection

It is possible to configure a multiple power supply system to shut down all the units when an “Output Off” command is sent or a fault condition occurs in one of the units.

Setup switch SW1 position 5 should be set to its Down position to enable the Daisy-chain operation. Other SW1 positions can be set according to the application requirements.

If any one supply turns off for any reason, its PS_OK signal will be set to low level and the display will indicate “Off” or the fault. The other units will shut off and their display will indicate a shut-off fault “SO”.

When the “Output On” command is sent or the fault condition is removed, the units will recover to their last setting according to their Safe start or Auto-restart setting.

6.4.1. Setting the Supplies for Advanced Parallel

The front panel is used to set a power supply as an Advanced Parallel master or slave. To set the master, it is required to know how many parallel slaves will be tied to its

output. a) Depress and hold the FINE button for 3 seconds. The default setting, “H1”, may

appear on the current display.

b) Rotate the current encoder to obtain the desired mode from the table below.

CURRENT Display Operating Mode

Table 6-1: Setting mode of operation

c) To lock in the new master or slave setting, wait a few seconds for the display to clear.

6.4.2. Master and Slave Units Default Operation

a) When a unit is programmed to Slave mode it enters the Remote mode with Local

Lockout. In this mode, the front panel controls are disabled. b) The slave front panel display will only show “On” or a fault condition. c) The Slave units parameters will automatically set the following:

 Output voltage to ~102% of rated output voltage  AST On  Programmed Current to zero  OUT On  UVL to zero volts  Foldback protection Off  OVP to its maximum value

d) The Master and Slave modes are stored in the power supply EPROM when the AC

power is turned off. The system will return to the Master/Slave mode upon re-

application of AC power.

6.4.3. Current Display Accuracy

In the advanced parallel mode, the Master unit does not display actual total current of all units in parallel. In this method, the CURRENT display accuracy is 2% +/- 1 count.

In cases that higher accuracy is required, it is recommended to use the basic parallel operation mode and get the current measurements from each supply and add them to get the total current.

83-530-000 Rev J

6.4.4. To Release From Slave Mode

Slave units can be released using the following procedure: a) Depress FINE button for 3 seconds. The current display changes to show the

master or slave setting. b) Select “H1” mode using the CURRENT encoder. c) Depress FINE button again or wait 5 seconds. d) Turn the AC power Off and On to store the new setting.

e) The front panel will be locked. Unlock it by depressing the PREView button until the

display shows “UFP”. f) After exiting from Slave operation the unit’s parameters will be set to:

 Programmed Voltage to zero  AST OFF  Programmed Current to zero  OUT OFF  UVL to zero volts  Foldback protection OFF  OVP to its maximum value  Locked Front Panel

7. REMOTE AND ANALOG PROGRAMMING

7.1. Introduction

The rear panel connector J1 allows the user to program the power supply output voltage and current limit with an analog device. J1 also provides monitoring signals for output voltage and output current. The programming 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 communication port is active and can be used to read the power supply parameters.

CAUTION

COM (J1-12), VPGM_RTN (J1-22) AND IPGM_RTN (J1-23) terminals of J1

connect internally to the -Sense potential (-LS). Do not connect these terminals

to any potential other than -Sense (-LS), as it may damage the power supply.

CAUTION

When the Isolated Analog Option is installed, do not apply any signals to the non-

isolated VPGM and IPGM (J1-9 and J1-10) pins. All other J1 features may be

used normally. Refer to Section 4.4 for a description of J1 features.

7.2. Local/Remote Analog Selection

Contact 8 of J1 (Fig.4-4) 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 limit.

In Local mode, the output voltage and current limit can be programmed via the front panel VOLTAGE and CURRENT encoders or via the RS232/485 port. In Remote Analog mode, the output voltage and current limit can be programmed by analog voltage or by programming resistors via J1 contacts 9 and 10 (Refer to Sections 7.4 and 7.5). Refer to Table 7-1 for Local/Remote Analog control (J1-8) function and Setup switch SW1-1, 2 setting.

7.3. Local/Remote Analog Indication

Contact 21 of J1 (Fig. 4-4) is an open collector output that indicates if the power supply is in Local mode or in Remote Analog mode. To use this output, connect a pull-up resistor to a voltage source of 30Vdc maximum. Choose the pull-up resistor so that the sink current will be less than 5mA when the output is in low state. Refer to Table 7-2 for J1-21 function.

7.4. Remote Voltage Programming of Output Voltage and Current Limit

CAUTION

To maintain the isolation of power supply and prevent ground loops, use an

isolated programming source when operating the power supply via remote

analog programming at J1 connector.

Perform the following procedure t o set the power supply to Remote Voltage programming:

a) Turn the power supply switch to Off. b) Set setup switch SW1 position1and2to their UP position. c) Set SW1 position 3 to select programming voltage range according to Table 7-3. d) Ensure that SW1 positions 3 to select programming voltage r ange according to Table 7-3. e) Connect a short between J1-8 and J1-12 (refer to Table 4-4). f) Connect the programming source to the mating plug of J1 as shown in Fig.7-1. Observe

correct polarity fo

r the voltage source.

g) Set the programming sources to the desired levels and turn the power supply ON. Adjust

the programming sources to change the power supply output.

NOTES:

1. SW1 positions, 4, 5, 6 and9are not required for remote programming. Their setting can be determined according the application.

2. The control circuits allow the user to set the output voltage and current limit up to 5% over the model-rated maximum value. The power supply will operate within the extended range, however it is not recommended to opera

te the power supply over

its voltage and current rating and performance is not guaranteed.

7.5. Resistive Programming of Output Voltage and Current Limit

For resistive programming, internal current sources, for output voltage and/or output current control, supply 1mA current through external programming resistors connected between J1-9 & 22 and J1-10 & 23. The voltage across the programming resistors is used as a programming voltage for the power supply. Resistance of 05Kohm or 010Kohm can be selected to program the output voltage and current limit from zero to full scale.

A variable resistor can control the output over its entire range, or a combination of variable resistor and series/parallel resistors can control the output over restricted portion of its range.

Perform the following procedure to set the power supply to Resistive programming: a) Turn the switch to off.

b) Set setup switch SW1 positions 1 and 2 to their UP position. c) Set SW1 position 3 to select programming resistor range according to Table 7-4. d) Set SW1 positions 7 and 8 to their UP position to enable resistive programming mode. e) Connect a short between J1-8 and J1-12 (referto Table 4-4). f) Connect the programming resistors to the mating plug of J1 as shown in Fig.7-2. g) Set the programming resistors to the desired resistance and turn the power supply ON.

Adjust the resistors to change the power supply output.

NOTES:

1. SW1 positions 4, 5, 6 and 9 are not required for remote programming. Their setting can be determined according to the application requirements.

3. To maintain the temperature stability specification of the power supply, the resistors used for programming should be stable and low noise resistors, with temperature coefficient of less than 50ppm.

4. When resistive programming is used, front panel and computer control (via serial communication port) of output voltage and current are disabled.

8.5.5. Checksum

The user may add a checksum (optional) to the end of the command. This ensures no data bits are corrupted by bad wires or noise. The checksum is “$” followed by two hex characters. If a command or a query has a checksum, the response will also have one. There is no CR between the command string and the “$” sign.

Example: STT?3A

STAT?$7B

8.5.6. Acknowledge

The power supply acknowledges received commands by returning an “OK” message. If an error is detected the power supply will return an error message. The rules of checksum apply also to the acknowledge.

8.5.7. Error Message

If an error is detected in command or query, the power supply will respond with an error message. Refer to Section 8.6 for details.

8.5.8. Backspace

The backspace character (ASCII 8) clears the last character sent to the power supply.

8.6. Error Messages

The power supply will return error messages for illegal commands and illegal programming parameters. Refer to Table 8-1 for programming error messages and Table 8-2 for commands error messages.

Table 8-1: Programming Error Messages

Error Code Description

E01 Returned when program voltage (PV) is programmed above acceptable range.

Example: PV above ‘105% of supply rating’

E02 Returned when programming output voltage below UVL setting. E04 Returned when OVP is programmed below acceptable range.

Example: OVP less than 5% of supply voltage rating’ plus ‘voltage setting’.

8.8. Global Output Commands

8.8.1. Description

Global commands are a way to quickly set all power supplies on the RS-232/485 bus to the same setting. For example, sending “GOUT OFF” is one way to turn a whole group of supplies OFF at nearly the same time.

After sending a global command, it is important that the controller wait

200 mSec before sending any more RS-232/485 messages.

If the command contains an error, such as incorrect syntax or range

values, NO error response will be returned by any power supply.

Table 8.5: Global Output Commands

1 GRST Reset. Brings the power supply to a safe and known state:

Output voltage: 0V, output current: 0A, OUT: Off, Remote: RMT 1, AST: Off OVP: Max, UVL: 0. The conditional register (FLT and STAT) are updated. Other registers are not

changed. Non-Latching faults (FB, OVP, SO) are cleared, OUT fault stays

8.9. Fast Queries

These are commands that read a response very quickly from the power supply. They use unprintable character codes. They allow the power supply to avoid the normal command processing delays.

The processing time for these queries is typically 2 mSec, so total query speed is 2 mSec plus the RS-232/485 transmission time.

Since these queries embed the power supply address (0 to 30), there is no need to first send the “ADR n” addressing command.

8.9.1. Fast Test for Connection

This is an addressed query that is good for scanning to see what supplies are “on line”. If no response is returned within 10 mSec, your control program has determined that no power supply is connected at that address.

Query Format:

Send two bytes of unreadable characters. First: Byte 1 = 1010 1010 = AA hex Byte 2 = 000x xxxx (where xxxxx is the address of the supply in binary)

Query Response:

The power supply returns 5 characters:

First a “1” = 31 hex if Multi-drop is enabled

or a “0” = 30 hex if Multi-drop is not enabled

Then four printable characters:

Dollar sign “$” Checksum (two ASCII hex characters) = “30” or “31” Carriage-return terminator

8.9.2. Fast Read Registers

This query allows fast polling of the status and error registers for many power supplies on a RS-232/485 link. It is useful for checking many supplies to verify they are all operating as expected.

Query Format:

Send two bytes of unreadable characters. First:

100x xxxx (where xxxxx is the address of the supply in binary)

And send it a second time:

100x xxxx send 2 characters sequentially

Query Response:

The power supply returns 16 characters including the contents of the status and fault registers (see section TBD and Figure TBD).

First twelve bytes contain binary data from six registers:

STAT? SENA? SEVE? FLT? FENA? FEVE?

Then four printable characters:

Dollar sign “$” Checksum (two ASCII hex characters) Carriage-return terminator

83-530-000 Rev J

8.9.3. Read Power-On Time

This query allows you to read how many minutes the power supply has been running since it was built. The accuracy, in minutes, is not guaranteed for time critical applications.

Query Format:

Send two bytes of unreadable characters. First: Byte 1 = 1010 0110 = A6 hex Byte 2 = 000x xxxx (where xxxxx is the address of the supply in binary)

Query Response:

The power supply returns 12 characters:

First is the minutes as a 32 Bit integer as 8 ASCII Hex bytes

Then four printable characters:

Dollar sign “$” Checksum (two ASCII hex characters) = “30” or “31” Carriage-return terminator

8.9.4. Service Request Messages

A Genesys power supply can automatically send messages over the RS-232/485 lines when there is a change in operating mode or if a fault occurs. These messages are called Service Requests or SRQs. They are setup with the RS-232/485 status registers (see Section 8.11 and 8.12).

Since the SRQ messages may be sent from any supply at any time, there is a chance they can collide with other messages from other supplies. Your controller software has to be developed enough to read messages that may come at any time, and to recover if messages are corrupted by collisions.

If you need Service Request messaging, please contact TDK-Lambda for assistance. We can provide several special communication commands and settings that will help with this.

8.10. Status and Error Commands

The following commands operate on the power supply status and error registers. They are used to read operating conditions and fault conditions, they can be set to latch changes in these conditions, and masks can be set up to send service requests messages if the conditions change.

Refer to Section 8.11 and Figure 8-7 for more instructions on using these register commands.

9. ISOLATED ANALOG PROGRAMMING OPTION

9.1. Introduction

Isolated Analog Programming is an internal option card for analog programming of the GenesysTMpower supply series. The option is factory installed and cannot be obtained with IEMD or LAN Interfaces. Output Voltage and Current Limit can be programmed and read back through optically isolated signals which are isolated from all other ground references in the power supply.

There are two types of Isolated Analog programming cards: a) 0-5V/0-10V option (PN: IS510): Using 0-5V or 0-10V signals for programming and

readback.

b) 4-20mA option (PN: IS420): Using current signals for programming and readback.

10. MAINTENANCE

10.1. Introduction

This Chapter provides information about maintenance, calibration and troubleshooting.

10.2. Units Under Warranty

Units requiring repair during the warranty period should be returned to a TDK-Lambda Americas Inc. authorized service facility. Refer to the addresses listing on the back cover of this manual. Unauthorized repairs performed by other than the authorized service facilities will void the warranty.

10.3. Periodic Maintenance

No routine maintenance of the power supply is required except for periodic cleaning. To clean, disconnect the unit from the AC supply and allow 60 seconds for discharging internal voltage. The front panel and the metal surfaces should be cleaned using a damp cloth containing a mild solution of detergent and water. The solution should be applied onto a soft cloth, and not directly to the surface of the unit. Do not use aromatic hydocarbons or chlorinated solvents for cleaning. Use low pressure compressed air to blow dust from the unit.

10.4. Adjustments and Calibration

No internal adjustment or calibration is required. There is NO REASON to open the power supply cover. This will void the warranty.
