CONTACT OPERATION
Normally open load contacts close and normally
closed load contacts open when the sensor
probes detect the influx of moisture within the
motor.
TEST PROCEDURE
A normally closed pushbutton and neon
indicating lamp are provided as means of
checking the moisture sensing components.
When the pushbutton is depressed, the
indicating lamp will be illuminated to indicate (A)
power is supplied to the control, (B) the control
is operative, and (C) wiring to the moisture
sensing probes in the motor is intact. This
procedure should be performed periodically to
confirm integrity of circuit.
SIGNAL DEVICES
The signal device may be audible (bell, buzzer,
horn or siren) or visible (incandescent or neon
lamp) or both - a signal device of your choice
may be obtained from your local electrical supply
house.
