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.
