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 push-button 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 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.
For integrating the PS-PRO HT into computer
control/touch screen systems use “momentary
mode.”
The PS-PRO HT main circuit board has 5 pairs
of terminals labeled as:
JMP1 (MAINT ON), when the REM and +12V
terminals are tied together, the PS-PRO will
sequence OFF.
JMP2 (MOMENTARY), when the REM and +12V
terminals are momentary tied together, the PS-
PRO will sequence ON or OFF.
JMP3 (MAINT OFF), when the REM and +12V
terminals are tied together, the PS-PRO will
sequence ON.
JMP4 (REM TO GND = ON), when the REM and
GND terminals are tied together, the PS-PRO
HT will sequence ON (Note: JMP1 must have a
jumper installed).
JMP5 spare jumper holder.
PS-PRO HT units come factory-set for maintained
operation (jumper is installed on JMP3). They
may be easily converted to other operating
modes by moving jumper plug/plugs on the
PS-PRO HT’s circuit board. To do this, first
disconnect the unit from AC power. Remove
the four screws that secure the top cover and
one screw from the front panel. Just install the
jumper plugs to the desired mode of operation.
Reattach the top cover.
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. Use this
setting when you want to use the RS-1 as a
remote controller.
(Continued on page 7)
(Continued from page 4)
Disconnecting initiates an ON sequence. If the
cable run is long, it is recommended that the
REM wire be tied to the PS-PRO HT’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) Defaut Setting
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 HT’s GND terminal during
OFF operation rather than leaving it floating.
REM to GND = ON (jumper plugs installed on
JMP1 and JMP4)
