Input #12 is the heat on status. It is used to monitor the Phase 5 microprocessor controller (computer) heat output. Input #12 in conjunction with input #13 (gas valve status), the PLC (Programmable Logic Controller) will monitor for a heater fault condition.

Input #14 indicates that the drying cycle is done (air jet signal). Once the output relay of the Phase 5 microprocessor controller (computer) turns on contact relay #4, input #14 is turned on. This in turn signals the PLC to illuminate the "END OF CYCLE" (E.O.C.) L.E.D. (light emitting diode) until the dryer is attended to.

Front door closed (input #15) is a safety circuit used to lock out the Phase 5 microprocessor controller (computer) from a drying cycle unless the doors are closed.

Lint door closed (input #16) monitors/verifies that the lint door is closed.

The front down/rear down/dryer level (input #17) is another safety device used so that a drying cycle cannot be initiated unless the dryer is in the level position.

(2)Output Relays

Output relay #210 controls the air supply to the top of the pneumatic piston to tilt the front of the dryer down.

Output relay #211 controls the air supply to the bottom of the pneumatic pistons to tilt the front of the dryer up, provided that the rear of the dryer is in the level position.

Output relay #212 is used to turn on the fan and cool the load after a heater fault.

Output relay #213 controls the air supply to the top of the pneumatic pistons to tilt the rear of the dryer down.

Output relay #214 controls the air supply to the bottom of the pneumatic pistons to tilt the rear of the dryer. Rear up (output relay #214) applies power to the S6 rear up solenoid through the front down level switch (LS1B).

The dryer "CLEAR/STOP" output (relay #215) is used to lock out the Phase 5 microprocessor (computer) from running a drying cycle. If the PLC (Programmable Logic Controller) has input #4 (front door open) and input #10 (blower [squirrel cage fan] on), or input #7 (lint door closed), input #15 (front door closed), or input #17 (dryer level) are off, then the PLC will close output relay #215 (dryer "CLEAR/STOP") so that a drying cycle cannot be initiated.
