b. HEAT ON pilot light.
When MAIN switch is thrown, power is applied to the
HEAT ON pilot light, heating element, and motor portions of the circuit. The HEAT
ON pilot light remains on as long as the MAIN switch is closed and the power is
being applied, to indicate the system is under power.
l
Heating element.
Input power is applied to the heating element via the
LOW/HIGH thermostat, override thermostat, and the coupled resistor and capacitor.
The heating element heats the wax tray and wax to the desired temperature.
d. LOW/HIGH thermostat.
Limits the temperature reached by the heating
element coils.
It is normally closed.
When the desired temperature is reached, the
thermostat opens and cuts power to the element.
e.
Inner pilot light.
Indicates when power is being applied to the heating
element.
It is coupled in parallel with heating element.
f. Coupled resistor and capacitor.
Coupled in parallel with LOW/HIGH thermostat
and override thermostat, and provide an RC time delay to keep the temperature of the
heating element from changing too fast when the LOW/HIGH thermostat setting is
changed.
They allow just enough power to reach the element to supply some heat but
not enough to maintain the former temperature.
Override thermostat.
Enables quick heat-up of wax coater by eliminating
the effect of the coupled resistor and capacitor.
It is closed during warm-up,
providing a path for input of power to the element.
It opens when minimum operating
temperature has been reached and does not reclose.
h. Motor thermostat.
Prevents power from being applied to the motor unless it
senses the wax coater is at the proper temperature.
It is normally open, but closes
when the wax has reached proper operating temperature.
i.
OPERATE pilot light.
Coupled in parallel with the motor to indicate when the
motor thermostat is closed and power can be applied to the motor.
j. AC motor.
Turns coating roller via two gears and a toothed belt. Power is
input to the motor via the motor thermostat and MOTOR switch.
8-3.2 Coating System.
Transports material through the wax coater and coats
one side with adhesive wax.
It is composed of the following components:
Top Pressure Roller
Coating Roller
Wax Tray
Stripper Fingers
Pressure Roller Gear
Meshed Gears
