Maintained switches are generally most convenient
when there is only one remote location. When
more than one switch location is required,
momentary switches allow the sequence to be
started from different locations.
PS-8R II main circuit board has 5 pairs of terminals
(PCB REV F and later) labeled as:
JMP1 (REM TO +12V = OFF, DEFAuLT ), when
the REM and +12V terminals are tied together,
the PS-8R II will sequence OFF.
jMP2 (MOMENTARy), when the REM and +12V
terminals are momentary tied together, the PS-8R
II will sequence ON or OFF.
JMP3 (REM TO +12V = ON), when the REM and
+12V terminals are tied together, the PS-8R II will
sequence ON.
JMP4 (REM TO GND = ON), when the REM and
GND terminals are tied together, the PS-8R II will
sequence ON (Note: jMP1 must have a jumper
installed).
jMP5, spare jumper holder.
The PS-8R II unit comes factory-set for maintained
operation (jumper is installed on jMP1). It may be
easily converted to other operations by moving
jumper plug/plugs on the PS-8R II's circuit
board.
To do this:
1. Disconnect the unit from AC power.
2. Remove the 10 top cover screws that secure
the top cover.
3. In the rear left corner of the circuit board you
will find the 5 pairs of terminals mentioned above.
Install the jumper plug on the terminal for the
mode of operation desired.
4. Reattach the top cover.
MAINTAINED MODE
There are three maintained modes of operation:
reM to +12V = off (jumper installed on

JUMPER SETTING CHART
JMp1)
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-8R II's GND terminal during ON operation
rather than leave 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)
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-8R II's GND terminal during OFF operation
rather than leave it floating.
reM to gnd = on (jumper plugs installed on
JMp1 and JMp4)
Connection of the REM terminal to the GND
terminal initiates an ON sequence. Disconnecting
initiates an OFF sequence.
