MAINTAINED Mode
There are 3 maintained modes of operation:
REM to +12V = OFF (jumper plug installed on JMP1, MAINT ON)
The connection of the REM terminal to the +12V terminal initiates an OFF sequence. Disconnecting initiates an ON sequence. If the cable run is long, it is recommended that the REM wire be tied to the PS-PRO II’s GND terminal during ON operation rather than leaving it floating. This will require the use of a third conductor and a double-throw switch.
REM to +12V = ON (jumper plug installed on JMP3, MAINT OFF)
The connection of the REM terminal to the +12V terminal initiates an ON sequence. Disconnecting initiates an OFF sequence. If the cable run is long, it is recommended that the REM wire be tied to the PS-PRO II’s GND terminal during OFF operation rather than leaving it floating.
REM to GND = ON (jumper plugs installed on JMP1 and JMP4)
The connection of the REM terminal to the GND terminal initiates an ON sequence. Disconnecting initiates an OFF sequence.

NOTE: DO NOT USE the “START ON-OFF SEQUENCE” switch on the front panel in Maintained Mode . If you do, you may activate an unintended sequence. If a Furman RS-1 is the controlling switch, contact Furman’s Tech Support department for the proper wiring diagrams.
Momentary Mode
In Momentary Mode (jumper plug installed on JMP2)
The PS-PRO II has “memory” — it only needs a momentary signal from the remote switch to change its state from ON to OFF. When first plugged in (or after power is lost and reapplied for any reason) the stored state is OFF, and the DELAY 1 LED will flash. The unit will stay off until sequenced ON by a momentary connection of the REM IN terminal to +12V (the key switch must be in the REM position). The sequence starts on the rising edge of the signal.
The front panel START ON-OFF SEQUENCE switch is in parallel with, and functionally equivalent to, one or more remote momentary switches that may be connected to the terminal strip in the rear.
The “memory” is independent of the key switch. This means that even if the unit is sequenced off by turning the key lock switch to OFF, when the key lock switch is turned back to REM, the unit will sequence back on — it will not be necessary to push the START ON-OFF SEQUENCE button again. The unit “remembers” its state until the incoming power is lost, in which case it would default back to OFF.
The front-panel key lock switch is not the primary means of control in the momentary mode and should normally be left in REM. It may be a useful secondary means of control in the rare case of having several PS-PRO II’s in parallel if there is some reason to shut down one unit without affecting the others. Because it is a maintained-
