Function
2.1
Spin Lock
Prior to the first commissioning, a lock is placed on the spin cycle.
This is to prevent appliance damage or personal injury, if, for example, the
spin cycle is accidentally activated while the appliance is on display with the
struts mounted or with an accessories kit stored in the drum.
The spin lock is in effect until the first water intake of 1.4" wc.
Note:
The spin lock is also in effect for service mode.
2.2
Toothed V-Belt
The toothed V-belt is elastic.
The toothed V-belt tension is the result of the fixed, non-adjustable distance
between the motor and the flywheel.
2.3
Motor Overheating Protection
The motor winding has a built-in temperature limiter (Klixon).
At increased winding temperature, the temperature limiter opens the
switching contact.
When the switching contact is open, the power electronic (ELP) switches the
motor off.
When the temperature drops to a normal level, the contact closes again.
2.4
Tachogenerator
A generator attached to the motor produces alternating voltage and
frequency, depending on motor speed.
The power electronic (ELP) calculates a spin-speed signal from the AC
frequency. Fault code: Refer to Section 070-3.31.
