FC-5B EHD FOOT OPERATED
REMOTE CURRENT AND CONTACTOR CONTROL
This remote control is designed for use with any power source
that employs a single (common) current and contactor control
14-pin Amphenol receptacle. It contains a potentiometer which
controls the current output when the Panel/Remote Switch
(PRS) on the power source is placed in the “Remote” position.
This remote control also consists of a switch when the PRS is
placed in the “Remote” position. Both the potentiometer and
switch are operated when the FC-5B EHD pedal is depressed.
See the schematic diagram in your respective power source
instruction literature.
Interconnection of these functions to the main power source is
provided by a single mating 30-ft. cable/plug assembly provided.
Make sure all primary power to power source is
disconnected before installing this control.
