local control only, and a jumper is installed
on JMP1 with no switch connected to the PS-
PRO II’s terminal strip, then a jumper should
be connected between the REM and +12V
terminals. Otherwise, turning the front panel
key switch to the REM position will turn the PS-
PRO II ON.
REMOTE CONTROL
When the PS-PRO II’s front panel key lock switch
is in the REM position, it can be controlled by
one or more switches in remote locations. In
the most basic configuration, only two wires
and an SPST switch are needed to initiate an
ON or OFF sequence. The switch may be either
a momentary or a maintained-contact type,
depending on a jumper setting inside the PS-
PRO II. If an additional wire is used, an LED may
also be installed at the remote end to indicate
that the power is on.
MOMENTARy vs. MAINTAINED
CONTACT SWITCHING
An on-off switch of either kind may be used
to actuate the PS-PRO II’s remote operation.
Maintained switches, such as most toggle
switches and push-on/push-off button switches,
(including the Furman RS-1 key lock switch),
stay open until switched, and then remain closed
until switched again. Momentary switches,
usually pushbutton types like the Furman RS-2
(which also provides a locking key switch), are
normally open and stay closed only as long as
the button is pressed.
Maintained switches are generally the most
convenient when there is only one remote
location. When more than one location is required,
momentary switches offer the advantage of
a turn-on or turn-off sequence which may be
started from any location.
The PS-PRO II main circuit board has 5 pairs of
terminals (PCB REV D and later) labeled as:
JMP1 (Default) (MAINT ON) , when the REM and
+12V terminals are tied together, the PS-PRO II
will sequence OFF.
JMP2 (MOMENTARy), when the REM and +12V
terminals are momentary tied together, the PS-
PRO II will sequence ON or OFF.
JMP3 (MAINT OFF), when the REM and +12V
terminals are tied together, the PS-PRO II will
sequence ON.
JMP4 (REM TO GND = ON), when the REM and
GND terminals are tied together, the PS-PRO
II will sequence ON (Note: JMP1 must have a
jumper installed).
JMP5 spare jumper holder.
PS-PRO II units come factory-set for maintained
operation (jumper is installed on JMP1). They
may be easily converted to other operating
modes by moving jumper plug/plugs on the PS-
PRO II’s circuit board. To do this, first disconnect
the unit from AC power. Remove the 12 screws
that secure the top cover. Simply install the
jumper plugs to the desired mode of operation.
Reattach the top cover.
