CHAPTER 1 GENERAL INFORMATION

1.1 USER MANUAL CONTENT

This user’s manual contains the operating instructions, installation instructions and specifications of the Genesys 5000W power supply series. The instructions refer to the standard power supplies, including the built-in RS232/485 serial communication. For information related to operation with the optional IEEE programming, refer to UserManual for PowerSupply IEEE Programming Interface.

1.2 INTRODUCTION

1.2.1 General description

Genesys power supplies are wide output range, high performance switching power supplies. The Genesys series is power factor corrected and operates from worldwide AC voltage range. Output

voltage and current are continuously displayed and LED indicators show the complete operating status ofthe power supply. The Front panel controls allow the user to set the outputparameters, the protection levels (Over-Voltage protection, Under-Voltage limit and Foldback) and preview the settings. The rear panel includes the necessary connectors to control and monitor the power supply operation by remote analog signals or by the built-in serial communication (RS232/485). GPIB programming and Isolated-Analog programming/monitoring are optional.

1.2.2 Models covered by this manual

1.2.4 Multiple output power system

The Genesys power supplies series can be configured into a programmable power

system of up to 31 units using the built-in RS232/RS485 communication port in the power supply and the RS485 linking cable provided with each power supply.

In a GPIB system, each power supply can be controlled using the optional GPIB controller (factory installed).

1.2.5 Control via the serial communication port

The following parameters can be programmed via the serial communication port:

1. Output voltage setting.

2. Output current setting.

3. Output voltage measurement.

4. Output on/off control.

5. Output current measurement.

6. Foldback protection setting.

7. Over-voltage protection setting and readback.

8. Under-Voltage limit setting and readback.

9. Power-supply start up mode (last setting or safe mode)

1.2.6 Analog voltage programming and monitoring

Analog inputs and outputs are provided at the rear panel for analog control of the power supply. The output voltage and the current limit can be programmed by analog voltage or by resistor, and can be monitored by analog voltage.The power supply output can be remotely set to On or Off and analog signals monitor the proper operation of the power supply and the mode of operation (CV/CC).

1.2.7 Parallel operation

Genesys power supplies of the same output voltage and current rating canbe paralleled in

master-slave configuration with automatic current sharingto increase power available.

1.2.8 Output connections

Output connections are made to rear panel bus-bars for models up to 100V and to a 4terminal wire clamp connector for models above 100V rated output voltage. Either the positive or negative terminal may be grounded or the output may be floated. Models up to 60VDC Rated Output shall not float outputs more than +/- 60VDC above/below chassis ground. Models >60VDC Rated Output shall not float outputs more than +/-600VDC above/below chassis ground. Contact factory for assistance with higher float voltage applications.

Local or remote sense may be used. In remote sense, the voltage drop on the load wires should be minimized. Refer to the specifications for the maximum voltage drop value.

1.2.9 Cooling and mechanical construction

The Genesys series is cooled by internal fans. At the installation, care must be taken to allow free air flow into the power supply via the front panel and out of the power supply via the rear panel. The Genesys power supplies have a compact and lightweight package

which allows easy installation and space saving inthe application equipment.

3.1 GENERAL

This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment. Connection to PC, setting the communication port and linking Genesys power supplies are described in Chapter 7.

WARNING

The Genesys series is intended only for installation in Restricted Access Location (RAL). Access to Hazardous parts (rear side of the power supply) shall be prevented after installation.

Genesys power supplies generate magnetic fields which might affect the operation of other instruments. If your equipment is susceptible to magnetic fields, do not position it adjacent to the power supply

NOTE

WARNING

through the front panel slits.

3.2 PREPARATION FOR USE

To avoid electric shock hazard, do not insert conductive parts

n order to be operational the power supply must be connected to an appropriate AC source. The AC source voltage should be within the power supply specification. Do not apply power before reading, Section 3.6 and 3.7.

Table 3-1 below, describes the basic setup procedure. Follow the instructions in Table 3-1 in the sequence given to prepare the power supply for use.

3.3 INITIAL INSPECTION

Prior to shipment this power supply was inspected and found free of mechanical or electrical defects. Upon unpacking of the power supply, inspect for any damage which may have occured in transit.

The inspection should confirm that there is no exterior damage to the power supply such as broken knobs or connectors and that thefront panel and meters face arenot scratched or cracked. Keep all

packing material until the inspection has been completed. If damage is detected, file a claim with carrier immediately and notify the Lambdasales or servicefacility nearest you.

3.4 RACK MOUNTING

The Genesys power supply seriesis designed to fit in a standard 19” equipment rack.

3.4.1 To install thePower Supply in a rack:

1. Use the front panel rack-mount brackets to install the power supply in the rack.

2. Use a support bar toprovide adequate supportfor the rear of the power supply. Do notobstruct

the air exhaust at the rearpanel of the unit.

WARNING

Some components inside the power supply are at AC voltage even when the On/Off switch is in the “Off”position. To avoid electric shock hazard, disconnect the line cord and load and wait two minutes before removing cover.

CAUTION

AC Input Wires No Conductor Pretreatment: Phoenix Contact clamping parts are designed so

that all kindsof copper conductors can be clamped withoutpretreatment. It is forbidden to solder the conductors. The solder tin yields and fractures under high pressure. The result is increased contact resistance and an excessive temperature rise. In addition, corrosion caused by pickling or fluxes has been observed on soldered conductor ends. Notch fractures at the transition point from the rigid tothe flexible conductorarea are also possible.

The power supply ON/OFFswitch is not the main disconnect device and does not completely disconnect all the circuits from the AC source. An appropiately rated disconnect device such as circuit breaker, type B plug on power cord, ...etc., shall be provided in the final installation. The disconnect device shall comply with UL/IEC 60950-1 requirements andshall be easily accessible.

3.7.1 AC Input Connector

3.9 CONNECTING THE LOAD

WARNING

Turn off the AC input power before making or changing any rear panel connection. Ensure that all connections are securely tightened before applying power.There is a potential shock hazard when using a power supply with a rated output greater than 40V.

3.9.1 Load Wiring

The following considerations should be made to select wiring for connecting the load to the power supply:

* Current carrying capacity of the wire (refer to 3.9.2) * Insulation rating of the wireshould be atleast equivalent to the maximum output voltage of

the power supply. * Maximum wire length and voltage drop (refer to 3.9.2) * Noise and impedance effectsof the load wiring (refer to 3.9.4).

3.9.2 Current Carrying Capacity

Twofactors must be considered when selecting the wire size:

1. Wires shouldbe heavy enough not to overheat while carrying the powersupply load current at the rated load, orthe current thatwould flow in the event the loadwires were shorted, whichever is greater.

at least

3.9.4 Noise and Impedance Effects

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twistedpairs 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 fromthe 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.

3.9.5 Inductive loads

Inductive loads can produce voltage spikes that may be harmful to the power supply. Adiode 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 thenegative output ofthe 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.

3.9.6 Making the load connections

WARNING

Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live 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 mountinghardware does not short the output terminals. Heavy connecting cables must have some form of strainrelief to prevent loosening the connections orbending the bus-bars.

8V to 100V Models

Refer to Fig.3-6 for connection of the load wires to the power supply bus-bars and to Fig.3-7 for mounting the bus-bars shield to the chassis.

WARNING

Hazardous voltages exist at the outputs and the load connections. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

CAUTION

Output Load Wires No Conductor Pretreatment: Phoenix Contact clamping parts are designed

so that all kinds of copper conductors can be clampedwithout pretreatment. It is forbidden to solder the conductors. The solder tin yields and fractures under high pressure. The result is increased contact resistance and an excessive temperature rise. In addition, corrosion caused by pickling or fluxes has been observed on soldered conductor ends. Notch fractures at the transition point from the rigid tothe flexible conductorarea are also possible.

The 150V to 600V models haveafour terminal wire clamp output connector: Phoenix Contact P/N: FRONT4-H-7.62/4 The two left terminals are the positive outputs and the other two right terminals are the negative outputs.Max. 30A per terminal. The connector requirements are as follows:

1. Wires: AWG18 to AWG10.

2. Tightening torque: 4.4-5.3Lb-inch. (0.5-0.6Nm).

Follow the below instructions for connection of the load wires to the power supply:

1. Strip approx.10mm at the end of each of the load wires.

2. Loosen the connector terminal screws.

3. Loosen screws “B” from enclosure bottom cover to release the shutter.

4. Insert stripped wires into enclosure bottom cover opening and then to the terminals, tighten the terminals screws securely (see fig.3-9)

3.9.11Grounding outputs

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

WARNING

Models up to 60VDC Rated Output shall not float outputs more than +/-60VDC above/below chassis ground. Models > 60VDC Rated Output shall not float outputs more than +/-600VDC above/below chassis ground.

WARNING

OUTPUT TERMINALGROUNDING

There is a potential shock hazard at the RS232/485 and the IEEE ports when using power supplies with rated or combined voltage greater than 400V with the Positive Output of the power supplies is grounded. Do not connect the Positive Output to ground when using theRS232/485 or IEEEunder the above conditions.

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.3-15 for sense connector location.

3.10.1 Sense wiring

WARNING

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 toprevent accidental contact with hazardous voltages.

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.

3.10.3 Remote sensing

WARNING

There is a potential shock hazard at the sense point when using power supply with a rated output voltage greater than 40V. Ensure that the connections at the load end are shielded to preventaccidental contact with hazardous voltages.

CAUTION

When using shielded sense wires, ground the shield in one place only. The location can be the power supply chassis or one of theoutput terminals.

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:

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

2. Remove the local sense jumpers from J2.

3. Connect the negative sense leadto terminal J2-5(-S) and the positivesense 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.

4. Turn Onthe power supply.

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 the AC On/Off 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 powersupply.

The J1 Programming and Monitoring connector is a DB25 subminiature connector located on the power supply rear panel. Refer to Table 4-4 for description of the connector functions. The power supply default configuration is Local operation which does not require connections to J1.For remote operation using J1 signals use the plug provided with power supply orequivalent type. It isessential to use plastic body plug to conform with Safety Agency requirements. If a shield is required for J1 wires, connect the shield to apower supply chassisground screw.

4.5.1 Making J1 connections

- J1 connector type: AMP, P/N:5747461-3

- J1 plug description: AMP, P/N:745211-7

- Wire dimension range: AWG26-22

- Extraction tool: AMP, 91232-1 or equivalent.

- Manual Pistol grip tool: Handle:AMP, P/N: 58074-1 Head:AMP, P/N: 58063-2

Before making any connection, turn the AC On/Off switch to the Off position and wait until the front panel displayhas turned Off.

CAUTION

The programming return terminals (12, 22 and 23) are referenced internally to the -V potential of the power supply. Do not attempt to bias any of these terminals relative to the

-V or any other potential. Use the Isolated Programming interface option to allow control from a programming source at a different potential relative to the power supply negative output.

CAUTION

To prevent ground loops and to maintain the isolation of the power supply when programming from J1, use an ungrounded programming source.

WARNING

There is a potential shock hazard at the output when using a power supply with rated output greater than 40V. Use wires with minimum insulation rating equivalent to the maximum output voltageof the power supply.

CHAPTER 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 frontpanel REM/LOC button to change theoperating mode to local.

- For information regarding remote analogprogramming refer toChapter 6.

- For information regarding usage ofthe serial communicationport refer to Chapter 7.

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

1. In constant voltage mode,the power supply regulates the output voltage at the selected value, while the load current varies asrequired by theload.

2. While the power supply operatesin constant voltage mode, the VOLTAGE LEDon the front panel

illuminates.

3.Adjustment of the output voltage canbe made when the power supply outputis enabled

(Output On) or disabled (Output Off). When the output is enabled,simply rotate the VOLTAGE encoder knob to program the outputvoltage. When the output is disabled,press the PREV button and then rotate the VOLTAGE encoder knob. The VOLTAGEmeter will showthe programmed output voltage for 5 seconds after the adjustment has been completed. Then the VOLTAGE meter will display "OFF".

4.Adjustment resolution canbe set to coarse or fine resolution. Press FINE button to select betweenthe lower andhigher resolution. TheFINE LED turns On when the resolution is set toFINE.

NOTE

If after completingthe 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 supplycurrent limit setting.

NOTE

The maximum and minimum setting values of the output voltage are limited by theOver Voltageprotection and Under Voltage limit setting. Refer to Sec.5.3 and 5.4 formore details.

5.2.2 Constant Current Operation

1. In constant current mode, the power supply regulates the output current at the selected value,

while the voltage varies with the load requirement.

2. While the power supply isoperating in constantcurrent mode, theCURRENT LED onthe front panel illuminates.

3.Adjustment of the output current limit can be made whenthe 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 limit 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 for5seconds 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.

4. 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, whilethe load current isincreased 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 VOLTAGEPROTECTION(OVP)

The OVP circuit protects the load in the event ofaremote or local programming error orapower 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 willshut down.

5.3.1 Setting the OVP level

The OVP canbe set when the power supply output is Enabled (On) or Disabled (Off). To set the OVP level, press the OVP/UVL button, so that theCURRENT meter shows"OUP".

The VOLTAGEmeter shows the OVP setting level. Rotate the VOLTAGE encoder knob to adjust the OVP level. The display will show "OUP" and the setting value for5seconds after the adjustment has been completed and then will returnto it's previousstate.

The minimum setting level is approx. 105% of the set output voltage, or the value in Table 7-6, whichever is higher. The maximum setting levelis shown inTable 5-1.

To preview the OVP setting, press OVP/UVL pushbutton so that the CURRENT display will show "OUP". At this time, the VOLTAGE display will show the OVP setting. After5seconds, the display will return to it's previous state.

5.3.2 Activated OVP protection indications

When the OVPis 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 OVPcircuit after it activates:

1. Reduce the power supply OutputVoltage setting below the OVP set level.

2. Ensure that the load andthe sense wiringis connected properly.

3. Thereare four methods to reset the OVP circuit.

3.1 Press OUT button.

3.2 Turn thepower supply Offusing theAC On/Off switch, wait until the frontpanel display turns Off, thenturn the power supply On using the AC On/Off switch.

3.3 Turn thepower supply output Off and then On using the SO control (refer tosect.5.7). In this method the power supply should beset to Auto-Restart mode.

3.4 Send OUT1 command via theRS232/485 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 OVPfunctions, allow the user to create a protection window forsensitive load circuitry.

5.4.1 Setting the UVL level

Setting the UVLcan be madewhen the power supply output is Enabled (On) or Disabled (Off). Toset 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 toit’s previous state. UVL setting values are limited at the maximum level to approximately 95% of the Output Voltage setting. Attempting to adjust the UVL above this limit will result in no response to the adjustment attempt. Theminimum 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 isuseful 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 from Constant 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 display " Fb" onthe VOLTAGE meter.

5.5.2 Resetting activated Foldback protection

There are four methods to reset an activatedFoldback protection.

1. Press the OUT button.The power supply output is enabled and the Output Voltage and current will return to their last setting. In thismethod, the Foldbackprotection remains armed,therefore if the load current is higher than the currentlimit setting, theFoldback protection willbe activated again.

2. Press the FOLD button to cancel theFoldback protection. The power supply output will be disabled

and the VOLTAGE display will show “OFF”. Press the OUT buttonto enable thepower supply output.

3. Turn the power supply output Off and then On using the SO control (refer tosect. 5.7). Inthis method the foldback protection remains armed, therefore if theload current ishigher than thecurrent limit setting the Foldback protection will be activated.

4. Turn the power supply Off using the ACOn/Off switch, waituntil the frontpanel 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. Inthis method, theFoldback protection remainsarmed, therefore if the load current is higher thanthe current limitsetting, the Foldbackprotection 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 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 output is disabled, the output voltage andcurrent fall tozero and theVOLTAGE 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 , inAuto-Restart mode, the output will be enabled after applyingAC 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 isuseful for connectingpower supplies in a “Daisy-chain” (refer to section 5.16). The SO control can be used also to reset the OVP and Fold Protection. Refer to sect. 5.3 and5.5 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 areoptically isolated fromthe power supply output. The SO control logic can be selected by the rear panel SW1 Setup switch. Refer to Table 5-2 for SW1 setting andSO 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 J1-13, 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 outputis low(0-0.6), with maximum 10mAsink current.

CAUTION

Do not connect CV/CC signal to a voltage source higher than 30VDC. Always connect CV/CC signal to the voltage source with a series resistor to limitthe sink currentto less than 10mA.

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 sourcecurrent of 2mA.The following faults will set the PS_OK to Fault state:

*OTP *OVP *Foldback *AC fail

*Enable/Disable open (Power supply is disabled) *SO (Rear panel Shut-Off - Power supply is shut off)) *IEEE failure (with optional IEEE interface) *Output Off

5.11 SAFE START AND AUTO-RESTART MODES

When turning on the power supply AC On/Off, 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 andAuto-restart modes. The VOLTAGE display will continuously cycle between "SAF" and "AU7” every 3 seconds. Releasing OUT pushbutton while one of the modes is displayed, selects that mode. The default setting at shipment is Safe mode.

5.11.1Automatic 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.

5.11.2Safe 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 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 shows "O7P" and the ALARM LED blinks. Resetting the OTP circuit can be automatic (non-latched) or manual (latched) depending on the Safe orAutomatic restartmode.

1. Safe start mode:

5.14 SERIES OPERATION

Power supplies of the SAME MODEL canbe connected in series to obtain increased output voltage. Splitconnection of the power supplies gives positiveand negative outputvoltage.

CAUTION

Do not connect power supplies from different manufacturers in series or in parallel.

5.14.1 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 of the units shuts down. Each diode should be rated to at least the power supply rated output voltage and output current. Refer to Fig.5-1 and 5-2 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, no point may be at a greater potential of +/-60VDC from ground for models up to 60VDC Rated Output and +/-600VDC from ground for models >60VDC Rated Output. When using RS232/485 or IEEE, refer to the OUTPUT TERMINALS GROUNDING warning, section 3.9.11.

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 remaining unitsare slaves. Theslave units areanalog programmed bythe master unit.

In remote digitaloperation, only the master unitcan be programmed by the computer while the slave units maybe connected to the computer for voltage, current and status readback only.

There are two methods, basic and advanced, to configure multiple supplies for parallel operation. Refer to Sec. 5.15.1 and toSec. 5.15.2 fordetailed explanation.

5.15.1 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. To program the load current, 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 simple parallel operation.

1. Setting up the Master unit

Set the master unit output voltage to the desired voltage. Program the current limit to the desired load current limit divided by the number of parallel units. During operation, the master unit operates 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.5-5.

2. Setting up the slave units

-1.The output 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 current limit of each unit should be programmed to the desired load current limit divided by the number of parallel units.

-2.Set the rear panel setup switch SW1 position 2 to it's up position.

-3.Set the rear panel setup switch SW1 position 3 in the same position as

SW1 position 4 of the master.

-4.Connect short between J1-8 and J1-12 (refer to Table 4-4.)

-5. Connect J1 terminal 10(IPGM) of the slave unit to J1 terminal 25(P) of the master unit.

-6. 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 output current. It is recommended that the power system is designed so that each unit supplies up to 95% of its current rating because of the imbalance which may be caused by cabling and connections voltage drop.

3. Setting Over Voltage protection

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. 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), only that unit would shut down and the remaining slave units would supply all the load current.

4. Setting Foldback protection

Foldback protection if desired, may only be used with the master unit. When the master unit shuts down it programs the slave units to zero output voltage.

5. Connection to the load

In parallel operation, power supplies can be connected in local or remote sensing. Refer to Fig.5-4 and 5-5 for typical connections of parallel power supplies. The figures show connection of two units, however the same connection method applies up to 4 units.

5.15.2 Advanced parallel operation

In this method, multiple supplies can be configured to parallel operation as a single power supply. The total load current and output voltage are displayed by the Master unit and can be readback from the Master unit. The Slave units display only their operating status (On, Off or Fault condition). Refer to the following procedure to configure multiple supplies for Advanced parallel operation.

1. Basic configuration Repeat steps 1 to 5 in Sec. 5.15.1 (Basic parallel operation).

2. Setting the unitsasMaster or Slave

a) Depress and hold the FINE button for3seconds. The Master/Slave configuration will be

displayed on the Current Display.Rotate the CURRENT encoder to obtain the desired mode.

Refer to Table 5-4 for the CURRENT display and modes of operation.

CURRENT Display

H1 H2 H3 H4

Operating Mode Single supply(default) Master supplywith1Slave supply Master supplywith2Slave supplies Master supplywith3Slave supplies Slave supply

Table 5-4: Setting mode of operation

b) When the desired configuration is obtained, depress and release the FINE button or wait approx. 5 seconds.

3. Master and Slave units default operation

a) When a unit is programmedto Slave mode it enters the Remote mode with Local Lockout. In this mode, the front panel controls are disabled to prevent accidental setting change (refer to Sec.

7.2.7 for details). b) The Slave unitsparameters will automatically set the following:

*Output voltage to approximate. 102% of rated output voltage. *ProgrammedCurrent to zero. *UVL to zero volts

*AST On *OUT On *Foldback protection Off

*OVP to itsmaximum value

c) The Master and Slave modes are stored in the power supply EEPROM when the AC power is

Turned off. The system will return to the Master/Slave mode upon re-application of AC power.

4. CURRENT display accuracy

In the advanced parallel mode, the total current is programmed and reported by the Master.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.

5. To release units from Slave mode

Slave units can be released using the following procedure: a) Depress FINE button for3seconds. The Master/Slave configuration will be displayed on the

CURRENT display. b) Select H1 mode using the CURRENT encoder. c) Depress FINE button again or wait 5 seconds. d) Turn the AC power Offto store the new setting. e) 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

1.In parallel operation, the AC Supply should be applied to the Master Unit first and then to the Slave unit.

2.The above sequence is not required if the units are connected in daisy-chain.

5.16 DAISY-CHAIN CONNECTION

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units. When the fault is removed, the system recovers according to its setting to Safe start mode or Automaticrestart. Setup switch SW1 position 5 should be set to its Down position to enable the Daisy-chain operation. Other SW1 positions can be setaccording to theapplication requirements. If a faultoccurs in one of the units its PS_OK signal will be setto low level and the display will indicate the fault. The other units will shut off and their display will indicate "SO”. When the fault condition is removed, the units will recover to their last setting according to theirSafe start orAuto-restart setting. Fig.5-6 shows connection of three units, however the same connection method applies to systems with a largernumber of units.

CHAPTER 6 REMOTE ANALOG PROGRAMMING

6.1 INTRODUCTION

The rear panel connector J1 allows the user to program the power supply output voltage and current limit with an analog device. J1also provides monitoringsignals 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 isactive and can be used to readthe power supply parameters.

CAUTION

COM (J1-12), VPGM_RTN (J1-22) and IPGM_ RTN (J1-23) terminals of J1 are referenced to the -Vout potential (-V). Do not connect these terminals to any potential other than -Vout(-V), as it may damage the power supply.

6.2 LOCAL /REMOTEANALOG CONTROL

Contact 8ofJ1 (Fig. 4-2, item 5) accepts TTL signal or Open-Short contact (referenced to J1-12) to select between Local or RemoteAnalog programming of the output voltage and currentlimit. 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 programmedby analog voltage or by programming resistors via J1 contacts 9 and 10 (refer to sec. 6.4 and 6.5). Refer to Table 6-1 for Local/Remote Analog control (J1-8) function and Setup switch SW1-1, 2 setting.

6.4 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 to set the power supply to Remote Voltage programming :

1. Turn the power supply AC On/Off switch to Off.

2. Set setup switch SW1-1 to its UP position for output voltage external programming and SW1-2 to its UP position for Output Current limit external programming.

3. Set SW1 position 3 to select programming voltage range according to Table 6-3.

4. Ensure that SW1 positions 7 and 8 are at their Down (default) position.

5. Connect a short between J1-8 and J1-12 (refer to Table 4-4).

6. Connect the programming source to the mating plug of J1 as shown in Fig.6-1. Observe correct polarity for the voltage source.

7. 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 and 9 are 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 operate the power supply over its voltage and current rating and performance is not guaranteed.

6.5 RESISTIVE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT

For resistive programming, internal current sources, for output voltage and/or output current control, supply 1mAcurrent 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 fullscale. A variable resistor can control the output over its entire range, or a combination of variable resistor and series/parallelresistors can control the output over restricted portion of its range.

Perform the following procedure to set the power supply to Resistive programming:

1. Turn the AC On/Off switch to Off.

2. Set setup switch SW1-1 to its UP position for output voltage external programming and SW1-2 to its UP position for Output Current limit external programming.

3. Set SW1 position 3 to select programming resistor range according to Table 6-4.

4. Set SW1-7 to its UP position for output voltage resistive programming and

SW1-8 to its UP position for Output Current limit resistive programming.

5. Connect a short between J1-8, J1-12 and J1-23 (refer to Table 4-4).

6. Connect the programming resistors to the mating plug of J1 as shown in Fig.6-2.

7. 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.

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 operate the power supply over its voltage and current rating and performance is not guaranteed.

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.

6.6 REMOTE MONITORING OF OUTPUT VOLTAGE AND CURRENT

The J1 connector, located on the rear panel provides analog signals for monitoring the output voltage and output current. Selection of the voltage range between 0-5V or 0-10V is made by setup switch SW1-4. The monitoring signals represent 0 to 100% of the power supply output voltage and output current.The monitor outputs have 500 ohm series output resistance. Ensure that the sensing circuit has an input resistance of greater than 500 Kohm or accuracy will be reduced. Refer to Table 6-5 for required J1 connection, SW1-4 setting and monitoring voltage range.

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 GPIB (IEEE) Interface. Output Voltage and Current Limit can be programmed and readback 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:

1. 0-5V/0-10V option (PN: IS510): Using0-5V or 0-10Vsignals for programming and readback.

2. 4-20mA option (PN: IS420): Using current signals for programming and readback.

Kapitel 9 Wartung & Service

9.1 Einleitung

Dieses Kapitel liefert Informationen über Wartung und Fehlersuche.

9.2 Reparaturen während der Garantie

Sollte ein Gerät innerhalb der Garantiezeit ausfallen, so dürfen Reparaturen nur durch Lambda oder autorisierte Servicestellen durchgeführt werden. Die Adressen finden Sie am Ende dieses Handbuches. Eingriffe in die Geräte durch nicht autorisierte Stellen führen zum Verlust des Garantieanspruches.

9.3 Periodische Wartung

Die Geräte sind wartungsfrei. Wir empfehlen jedoch die regelmäßige Reinigung. Trennen Sie die Einheit vom Versorgungsnetz und warten Sie 30 Sekunden um sicherzugehen, dass sich interne Spannungen abgebaut haben. Die Frontabdeckung und die Metalloberflächen sollten mit einer milder Lösung von Reinigungsmittel und Wasser gesäubert werden. Die Lösung sollte auf ein weiches Tuch aufgetragen werden, und nicht direkt auf Oberfläche der Geräte. Benutzen Sie keine Reinigungsmittel die aromatische Kohlenwasserstoffe, Chlor Lösungsmittel enthalten. Benutzen Sie schwach komprimierte Pressluft, um das Gerät von Staub zu befreien.

9.4 Justagen und Kalibrierung

Interne Justage oder Kalibrierung ist nicht nötig. Es gibt keinen Grund, die Stromversorgung zu öffnen.

9.5 Bauteilewechsel und Reparaturen

Da Reparaturen nur durch den Hersteller oder autorisierte Servicestellen durchgeführt werden dürfen, enthält das Handbuch keine Schaltpläne. Im Falle eines defektes oder ungewöhnlichem Verhalten des Gerätes, setzen Sie sich bitte mit der nächstgelegenen Lambda Niederlassung in Verbindung. Die Adressen finden Sie am Ende dieses Handbuches.

9.6 Fehlersuche

Sollte die Stromversorgung nicht wie erwartet funktionieren, kann ihnen die nachfolgende Tabelle helfen, herauszufinden ob die Stromversorgung, die Last oder eine externe Steuerung die Ursache dafür ist.

Stellen Sie das Netzgerät so ein, dass es mit den Reglern und Tasten am Frontpanel bedient werden kann. Führen Sie dann die Tests aus Abschnitt 3.8 durch um festzustellen, ob das Problem durch das Netzgerät verursacht wird.

Tabelle 9-1 führt Sie Schritt für Schritt durch die Prüfungen, die durchgeführt werden sollten, um die Fehlerursache zu ermitteln und gibt ihnen Hinweise auf Abschnitte dieses Handbuches in denen Sie weiterführende Informationen finden können.
