2.6.1 Multiple MPS Remote Inhibit Mode

In multiple MPS configuration, if the MPS RI indicators activate from an external contact closure, the MPS

units enter Multiple MPS Remote Inhibit Mode. They activate output overvoltage protection circuits and turn off

output circuits. If a charged load is present, OVP circuits discharge it. The front panel Fault annunciators turn

ON, and the internal audio indicators beep about once per second. If a MPS detects a fault, it initiates Multiple

MPS Remote Inhibit Mode by closing the FLT contacts. No delay is allowed (CAL AND ID switch 7 OFF, down

position) and multiple MPS operation (CAL AND ID switch 4 ON, up position) must be selected. After the load

discharges, turn OFF all units to reset.
