Maintained Mode

PS - PRO HT - POWER CONDITIONER/SEQUENCER

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

aturn-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.

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.

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)
