American Dryer Corp. WDA-385 用户手册

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 coin microprocessor controller

(computer) program related to this circuit (PL01) 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

non-active mode (nSEn).

4. "Hot" -

indicates a possible overheating condition. The Phase 5 coin microprocessor controller

(computer) monitors the temperature in the dryer at ALL times. If the microprocessor

controller detects that the temperature in the dryer has exceeded 220ºF (104ºC), it will

disable ALL outputs (shut the dryer down), the tone (bUZ) will sound for approximately 5

seconds, and the L.E.D. display will read "Hot." The L.E.D. display will continue to read

"Hot" until the temperature sensor has dropped to 220ºF or lower and the microprocessor

controller is manually reset by closing and opening the program switch (PS) on the back

side of the controller (as shown in the illustration on the next page).

L.E.D. Display Indicators

The L.E.D. indicator dots located at the top portion of the L.E.D. display (as shown in the illustration

below) insicate the Phase 5 coin microprocessor controller (computer) output functions while a cycle is in

progress. These dots do not necessarily mean that the outputs are functioning. They are only indicating

that the function (output) should be active (on).

1. Heat Circuit Indicator - indicator dot is on whenever the Phase 5 coin microprocessor controller

is calling for the heating circuit to be active (ON).

2. Motor Circuit Indicator - indicator dot is on whenever a cycle is in progress.

Microprocessor Controller Relay Output L.E.D. Indicators

There are three (3) L.E.D. indicators (red lights) located at the lower backside area of the controller are

identified/labeled "DOOR," "MTR," and "HEAT" (as shown in the illustration on the next page). These

L.E.D.'s indicate that the outputs of the Phase 5 coin microprocessor controller (computer) or, in the case

of the door switch , the input is functioning.

1. "DOOR" L.E.D. indicator should be on ALL the time (even if the dryer is not running) unless the main

door is open or there is a problem (open circuit) in the main door switch circuit.
