P. MOTOR CONTACTOR (1Ø MOTOR)
This motor contactor used on a single-phase (1ø)
dryer, is located in the rear of the dryer, in the electrical
panel box. Its purpose is to transfer the higher voltage
to the motor, when the contactor coil voltage has been
achieved.
Q. NON-REVERSING CONTACTOR (3Ø MOTOR)
The non-reversing contactor is used on 3-phase (3ø)
non-reversing dryers and is located on the upper left
hand side of the dryer (view from the rear). Its
purpose is to transfer the higher voltage to the motor,
when the contactor coil voltage has been achieved.
R. REVERSING RELAY PANEL
This panel is located in the back of the
dryer at the upper left hand corner. On
this panel is an arc suppressor board,
which filters out “noise” that might go to
the coils of the contactors. Also, mounted
on this panel are the drive and blower/fan
contactors. The 2-pole circuit breaker is
used to protect L1 and L3 on 460-480 VAC
models only. The transformer is stepping
down the incoming voltage to 24 VAC, to
supply the voltage to the computer and
controls.
