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.
-Enabled output, power supply in Constant Voltage mode: Press the PREV button and then ro- tate 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.
5.4 A 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).
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). When the unit is shut-off by a J1 signal, the VOLTAGE display will show “SO” to indicate the unit 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 5.11 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 with the output Enabled (Auto-restart mode) or start with the output Disabled (Safe-start mode).
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. Set the Current of each power supply to the maximum that the load can handle without damage. It is recommended that di- odes be connected in parallel with each unit output to prevent reverse voltage during start up se- quence or in case one unit shuts down.
3. Programming by external resistor: Programming by external resistor is possible. Refer to Section 6-5 for details. 4. Programming via the Serial The communication port is referenced to the IF_COM Communication port (RS232/RS485): 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.
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 remain- ing units are Slaves.
6. 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 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.

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.
REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT 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.
Page 56
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.
6.6 REMOTE MONITORING OF OUTPUT VOLTAGE AND CURRENT The J1 connector, located on the rear panel provides analog signals for monitoring the Output Volt- age and Output Current. Selection of the voltage range between 0-5V or 0-10V is made by setup switch SW1-4.
CHAPTER 7 RS232 & RS485 REMOTE CONTROL 7.1 INTRODUCTION This Chapter describes the operation of the Genesys 5000W power supplies via the serial commu- nication port. Details of the initial set-up, operation via RS232 or RS485, the command set and the communication protocol are described in this Chapter.
2. There are two Remote modes: 1. Remote: In this mode, return to local can be made by the front panel REM/LOC or via serial port command RMT 0. Set the unit into Remote mode via serial port RMT 1 command. 2.
7.4 MD MODE OPTION (Factory Installed) 7.4.1 MD Mode Description The GEN supply is capable of operating in a multi drop environment - more than 1 supply conducting serial communications on a single serial bus. A maximum of 31 GEN supplies can operate in this sin- gle bus.

7.5.2 Multi power supply connection to RS232 or RS485 bus Up to 31 units can be connected (daisy chained) to the RS232 or RS485 bus. The first unit connects to the controller via RS232 or RS485 and the other units are connected via the RS485 bus. 1.
7.6.7 Error message If an error is detected in command or query, the power supply will respond with an error message. Refer to Section 7.7 for details. 7.6.8 Backspace The backspace character (ASCII 8) clears the last character sent to the power supply. 7.7 ERROR MESSAGES The power supply will return error messages for illegal commands and illegal programming parame- ters.

7.10 SINGLE BYTE COMMANDS 7.10.1 General Single byte commands are commands in which all the necessary data for the supply to act upon is contained in a single byte. Single byte commands will be executed immediately by the supply. If the command requires data to be sent to the HOST PC or IEEE Board (see sections 7.10.4 and 7.10.3.1) that response will be transmitted immediately with no delay due to any software overhead.
addressed supply and all non-addressed supplies, will respond to this command; but only the cur- rently addressed supply (if any) will respond with the ‘OK’. 7.10.4 Addressed commands with response 7.10.4.1 Read registers Send (0x80 + Address) (1 byte binary - send 2 times sequentially). The supply will return the contents of the Status Condition Register, the Status Enable Register, the Status Event Register (SEVE?), the Fault Condition Register, the Fault Enable Register and the Fault Event Register IFEVE/).

CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION 8.1 INTRODUCTION Isolated Analog Programming is an internal Option Card for analog programming of the Genesys power supply series. The option is factory installed and cannot be obtained with a GPIB (IEEE-488) Interface. Output Voltage and Output Current can be programmed and readback through optically iso- lated signals which are isolated from all other ground references in the power supply.
8.3 ISOLATED PROGRAMMING & MONITORING CONNECTOR Refer to Table 8-1 for detailed description of the rear panel Isolated Programming & Monitoring connector. To provide the lowest noise performance, it is recommended to use shielded-twisted pair wiring. Refer to Fig.8-1 for description of the Isolated Analog Programming & Monitoring connector. Isolated programming plug P/N: MC1.5/8-ST-3.81, Phoenix.
8.4 SETUP AND OPERATING INSTRUCTIONS CAUTION To prevent damage to the unit, do not program the output voltage and current to higher than the power supply rating. 8.4.1 Setting up the power supply for 0-5V/0-10V Isolated Programming and Monitoring Perform the following procedure to configure the power supply: 1.
