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-
