Table 7-1: Front panel setup

7.2.1 Default Setting Refer to Table 5-7: Memory parameters.

7.2.2 Address Setting The power supply address can be set to any address between 1 and 31.

1. Press REM button. The REM LED illuminates. ”  ” message appears on the Current display. 2. Press Current encoder. Voltagedisplay shows ”  ” andCurrent display shows present address. 3. Rotate the Current encoder to select required address. 4. Press Current encoder to enter selected parameter to memory. 5. When parameter is accepted the display blinks once and returns to the previous level. 7.2.3 Communication Interface Selection Z + power supply can be configured for RS232, RS485 or USB(*) communication interface. 1. Press REM button. The REM LED illuminates. ” N ” message appears on the Voltage display. 2. Press Voltage encoder. Voltagedisplay shows ” N ” andCurrent display shows communication interface. 3. Rotate the Current encoder to select the required interface. 4. Press Current encoder to enter selected parameter to memory. 5. When parameter is accepted the display blinks once and returns to the previous level. * Do not connect or disconnect the USB cable when the PS is operating.
