SECTION VIII

PHASE 5 OPL SYSTEM DIAGNOSTICS

ALL major circuits, including door, microprocessor temperature sensor, heat and motor circuits are monitored. The Phase 5 OPL microprocessor controller will inform the user, via the LED display, of certain failure codes, along with indicators both in the LED display and the outputs of each relay, (and door switch circuit) to easily identify failures.

Diagnostic (LED Display) Failure Codes

1."door" - indicates door switch circuit is open.

a.Keyboard entry was made while main door or lint drawer is open, or b.There is a fault in the door switch circuit (external of the Phase 5 OPL

microprocessor controller)

2."dSFL" - indicates a fault in the microprocessor temperature circuit.

If fault is detected in the microprocessor heat sensor circuit, the display will read "dSFL", and the

tone (buzzer) will sound for approximately 5 seconds every 30 seconds until...

a.The problem is corrected, or

b.Power to the dryer is discontinued and the problem is then corrected

IMPORTANT: The Phase 5 OPL microprocessor controller has its own internal heat sensing circuit fuse protection located on the back side of the Phase 5 OPL computer. If a "dSFL" condition occurs, check to see if this fuse has blown. If it has,

DO NOT replace the entire Phase 5 OPL microprocessor controller, replace the fuse and do so with a 1/8 amp (Slo-Blo) fuse ONLY.

NOTE: Once the Phase 5 OPL microprocessor controller detects a problem in the heat circuit, it updates every 30 seconds. If the problem was a loose connection in this circuit which corrected itself, the "dSFL" condition would automatically be cancelled.

3."SEFL" - indicates rotational sensor circuit failure meaning that there is a fault somewhere in the basket (tumbler) rotation detection circuit, or the Phase 5 OPL microprocessor controller program related to this circuit (Program Location 2) is set incorrectly in the active mode (SEn) where the dryer is not equipped with the optional rotational sensor and should be set in the nonactive mode (nSEn).

4."Hot" - indicates a possible overheating condition. The Phase 5 OPL microprocessor controller monitors the temperature in the dryer at all times. If the microprocessor controller detects that the temperature in the dryer has exceeded 220º F (104ºC), it will disable all outputs (shut the dryer down), the tone (bUZ) will sound for approximately 5 seconds, and the LED display will read "Hot" until the temperature has dropped to 220º F or lower and the Phase 5 OPL microprocessor controller is manually reset by pressing the "Clear/Stop" key.
