DLM 600W Series Isolated Remote Analog Interface Operation
M51A Option 2-11
3. Connect a jumper from Pin-13 to Pin-12.
4.
Connect a jumper from Pin-11 to Pin-23.
5.
Program the other parameters to the desired limit values: VOLTAGE PROGRAMMING
INPUT, Pin-9, and the OVP PROGRAMMING INPUT, Pin-3, with respect to pin-12.
6.
Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE
connector to Pin-15.
2.5 EXTERNAL-OFF Control
The EXTERNAL-OFF control input provides the same functionality as the OUTPUT switch on
the front panel. When asserted, it will turn off the output converter, discharge the output
capacitors with the downprogrammer, and reset the OVP and FAULT monitors. The signal
could be configured to be either active-low or active-high with the INTFC SETUP switch on the
rear panel.
Set Position-6, /EXT-OFF, to the OFF (down) position to select the active-high logic level for
asserting EXTERNAL-OFF. Set Position-6, /EXT-OFF, to the ON (up) position to select the
active-low logic level for asserting EXTERNAL-OFF. The logic-high level could be produced
with a voltage source within the range of 3-30VDC, and would be connected to Pin14, positive,
and Pin-2, return. The circuit is SELV, and has electrical isolation from the output of the unit.
2.6 Remote Monitoring
Analog signals are available for monitoring the output voltage and current. These signals vary
proportionally to the output parameters, and have user selectable ranges of 0-5VDC, 0-10VDC,
or 4-20mA for an output change from zero to full scale. Refer to Table 2–4 for information on
configuring the monitors.
