  • Page 39: Connecting The Load

    3.9. Connecting the Load WARNING Turn Off the AC input power before making or changing any rear panel connection. Ensure all live circuits are discharged and 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.
  • Page 40 3.9.2. 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.
  • Page 41 3.9.5. Connecting Single Loads, Remote Sensing Fig.3-4 shows recommended remote sensing connection for single loads. Remote sensing is used when, in Constant Voltage mode, the load regulation is important at the load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either at the power supply chassis or the load ground.
  • Page 42 3.9.6. Multiple Load Connection with Distribution Terminals If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-6).

SUPPLY SUPPLY Fig. 6-1: Series connection, local sensing Fig. 6-2: Series connection, remote sensing Remote programming in series operation for increased output voltage: Programming by external voltage: The analog programming circuits of this power supply are referenced to the negative Sense (-S) potential.
  • Page 62 6.1.2. Series Connection for Positive and Negative Output Voltage In this mode, two units are configured as a positive and negative output. 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 or in case one of the units shuts down.

  • Page 63: Parallel Operation

    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.
  • Page 64 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. WARNING Failing to set the slave supply voltage setting high enough will cause the slave to go into constant voltage (CV) mode.
  • Page 65 6.2.6. Connection to the Load In parallel operation, power supplies can be connected in local or remote sensing.

Setup switch SW1 position 5 should be set to its Down position to enable the Daisy-chain operation.
  • Page 67 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.
  • Page 68 6.4.4. To Release From Slave Mode Slave units can be released using the following procedure: Depress FINE button for 3 seconds. The current display changes to show the master or slave setting. Select “H1” mode using the CURRENT encoder. Depress FINE button again or wait 5 seconds. Turn the AC power Off and On to store the new setting.

    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.

    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).

    Refer to Fig. 8-7 for the Status and Error Registers Diagram. NOTE: these registers operate in a way that is similar to the IEEE-488 and SCPI registers (as used by the Genesys™ with the “-IEMD” option), but the structure and command set is different.
  • Page 86 Conditional Registers The fault Condition Register and the Status Condition Register are read only registers that the user may read to see the condition of the supply. Refer to Table 8-8 for description of the Fault Condition Register bits and Table 8-9 for the Status Condition register bits.

    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 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.

    9.3. Isolated Programming & Monitoring Connector Refer to Table 9-1 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.9-1 for description of the connector. Isolated programming plug P/N: MC1.5/8-ST-3.81, Phoenix.
