VII-3. Remote Control Pendant
A "REMOTE HAND HELD CONTROL PENDANT" is provided to allow operation of the power unit at
a distance of up to 50 feet (15 meters) and can be extended using 50 foot extension cables. The
"REMOTE HAND HELD CONTROL PENDANT" is connected to the control panel via a multiconnector
plug.
This remote can be used to check all the electrical control valves by simply disconnecting the wire to the
engine oil pressure switch and pushing in the safety shut down button and then turning on the star switch
to the on position. Once this is done, you can walk over to the valves while holding the pendant in your
hand. As you switch the valves you can see the lighted connectors go on and off on the top of the four
solenoids: clamp open, close & drive forward and reverse.
