The dryer system is divided into a number of “electrical” sections which are as follows:
1. Right Front Control Panel
The RIGHT FRONT CONTROL PANEL is located in the Right Front Control Cabinet of the dryer. This
panel is the heart of the drying system, where ALL control signals interface to or from this panel. The
signals that interface to this panel are too many to list here, however, they are ALL identified on TB1 of its’
schematic diagram.
2. Right Base Electrical Enclosure
The RIGHT BASE ELECTRICAL ENCLOSURE is located towards the front of the right base section. An
industrial multi-pin connector is used to connect the base section control signals to the tumbler section’s main
control panel. This electrical enclosure is labeled CAUTION, HIGH VOLTAGE IS PRESENT IN
THIS ENCLOSURE and incorporates the following electrical devises:
•The MAIN ELECTRICAL POWER to the machine
•The ELECTRICAL CONNECTION for the “OPTIONAL” SPRINKLER CIRCUIT POWER
•The THERMAL/MAGNETIC OVERLOAD and REVERSING CONTACTOR for the TUMBLER
MOTOR
•The THERMAL/MAGNETIC OVERLOAD and REVERSING CONTACTOR for the BLOWER
MOTOR
3. Right Base Interface Junction Box
The RIGHT BASE INTERFACE JUNCTION BOX is located towards the rear of the right base section
and is used as a central location to interface the base section electrical components to the TILTING tumbler
section. An industrial multi-pin connector is used to connect the base section control signals to the tumbler
section’s main control panel. The control signals incorporated in the Right Base Interface Junction Box are:
SOLENOID CONTROL
•Front Up / Front Down
•Rear Up / Rear Down
•Open Front Door
•Supply Air Enable
•Air Jet
LINT DRAWER / GUARD STATUS
TUMBLER TEMPERATURE and HI-LIMIT INFORMATION
TUMBLER LEVEL SENSE
• Front Level Switch
• Rear Level Switch
OPTIONAL SPRINKLER CONTROL SIGNALS
