CHAPTER 3 INSTALLATION 3.1 GENERAL This Chapter contains instructions for initial inspection, preparation for use and repackaging for shipTM ment. Connection to PC, setting the communication port and linking Genesys power supplies are described in Chapter 7. 3.2 PREPARATION FOR USE NOTE 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.
3.4.2 Rack Mount Slides (optional): CAUTION Ensure that the screws used to attach the slides to the unit do not penetrate ore than 6mm into the sides of the unit. Use rack mount slides: General Devices P/N: CC3001-00-S160 or equivalent to install the unit in a standard 19” equipment rack. Refer to Fig. 3-1 for slides assembly instructions. Use three #10-320x0.38”(max.) screws at each side. To prevent internal damage, use the specified screw length only. Fig. 3-1: Rack-mount slides assembly 3.
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. 3.7.1 AC Input Connector, 1500W models The AC input connector is a 3-Terminal wire clamp located on the rear panel. Use suitable wires and tightening torque as follows: 1. Wire diameter: 12AWG or 10AWG. 2. Tightening torque: 6.5 - 7.0 Lb-inch. 3.7.
4. Route the AC wires to the input connector terminals as required. To connect the wires, loosen the terminal screw, insert the stripped wire into the terminal and tighten the screw securely (4.4-5.3 Lb-inch). 5. Route the wires inside the cover to prevent pinching. Fasten the cover to the unit using the M3x8 Flat Head screws provided. Refer to Fig.3-3 for details. L N Cover M3x8 Flat Head screws (2 places) Assembled Strain Relief Fig.3-3: AC input cover and strain relief, 1500W models 3.
2. Connect the unit to an AC source as described in Section 3.7. 3. Connect a DVM with appropriate cables for the rated voltage to the output terminals. 4. Turn the front panel AC power switch to On. 3.8.3 Constant Voltage Check 1. Turn on the output by pressing the OUT pushbutton so the OUT LED illuminates. 2. Observe the power supply VOLT display and rotate the Voltage encoder. Ensure that the Output Voltage varies while the VOLT encoder is rotated.
3.8.7 Foldback Check WARNING Shorting the output may expose the user to hazardous voltages. Observe proper safety procedures. Refer to Section 5.5 for explanation of the FOLD function prior to performing the procedure below. 1. Ensure that the Output Voltage is set to approx. 10% of the unit rating. 2. Adjust the CURRENT encoder to set the Output Current setting to approx. 10% of the unit rating. 3. Momentarily press the FOLD button. Ensure that the FOLD LED illuminates.
2. Wire size should be selected to enable voltage drop per 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 consumption from the power supply and poor dynamic response to load changes. Please refer to Tables 3-2 and 3-3 for minimum wire length (to limit voltage drop) in American and European dimensions respectively.
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 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.

WARNING OUTPUT TERMINAL GROUNDING There is a potential shock hazard at the RS232/RS485 and the IEEE ports when using power supplies with rated or combined voltage greater than 400V with the Positive Output of the power supplies grounded. Do not connect the Positive output to ground when using the RS232/RS485 or IEEE under 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.
3.10.3 Remote sensing WARNING There is a potential shock hazard at the sense point when using a power supply with a rated Output Voltage greater than 40V. Ensure that the connections at the load end are shielded to prevent accidental 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 the output terminals. Use remote sense where the load regulation at the load end is critical.

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 front panel REM/LOC button to change the operating mode to Local. -For information regarding Remote Analog Programming, refer to Chapter 6.
-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 Output Current 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 Output Current. 4. Adjustment resolution can be set to Coarse or Fine adjustment.
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.
AC power; even if SO is at an Off level). After an On to Off transition 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 useful for connecting 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).
low, with a maximum sink current of 1mA; when no fault condition occurs, the PS_OK level is high with a maximum source current of 2mA. The following faults will set the PS_OK to a Fault state: *OTP *Enable/Disable open (Power supply is disabled) *OVP *SO (Rear panel Shut-Off, Power Supply is shut off) *Foldback *IEEE failure (With optional IEEE interface) *AC fail *Output Off 5.
5.14 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 Do not connected 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.
3. Programming by external resistor: 4. Programming via the Serial Communication port (RS232/RS485): Programming by external resistor is possible. Refer to Section 6-5 for details. The communication port is referenced to the IF_COM which is isolated from the power supply output potential. Therefore power supplies connected in series can be daisy-chained using the Remote-In and Remote-Out connectors. Refer to Chapter 7 for details. 5.14.
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 units are Slaves. The Slave units are analog programmed by the Master unit. In remote digital operation, only the Master unit can be programmed by the computer, while the Slave units may be connected to the computer for voltage, current and status readback only.
6. Connection to the load In parallel operation, power supplies can be connected in local or remote sensing. Refer to Fig. 54 and 5-5 for typical connections of parallel power supplies. The figures show the connection of two units, however the same connection method applies for 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.
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 Master unit calculates the total current by multiplying the Master output current by the number of Slave units. In this method, the CURRENT display accuracy is 2% +/- 1 count.

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 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.
6.4 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND OUTPUT CURRENT CAUTION To maintain the power supply isolation and to prevent ground loops, use an isolated programming source when operating the power supply via remote analog programming at the 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, positions 1 and 2 to their UP position. 3.
6.5 RESISITIVE 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 05Kohm or 010Kohm can be selected to program the Output Voltage and Output Current from zero to full scale.
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.
