X308: Imbalance input
The function of the imbalance input is to stop the motor if the drum’s
movement is too great. (The imbalance switch is normally open.) When
the imbalance switch is activated (closes) a voltage of 96 - 276 V AC is
supplied to the MCU. The MCU detects that imbalance has arisen and
stops the motor.
Input voltage: 120 V-20 % (=96 V) - 240 V+15 % (=276 V), 50/60 Hz
The imbalance input receives its supply from Input lock
sequence (X302).
Current:
Max. 0.01 A
X311: Main input
Input voltage: Single-phase or DC three-phase: 200 V-15%(=170 V) -
240 V+10% (264 V)
X312: Output to motor and input thermal protection device (Klixon)
The output is connected to a thermal protection device, located on the
motor windings, with a connection back to the input. If the motor
becomes overheated, the thermal protection device switch opens. The
yellow LED reveals an error code through its pattern of flashes, see the
section “Error indication patterns”.
Current, max. 0.01 A
