the rear of tub assy.
NOTE ON OUT OF BALANCE DETECTION.
•The timers used on these machines have Out OfBalance detection on the module and
operate in the following way.
•At the start of the spin sequence as the machine ramps to 95rpm, the load on the motor
is monitored as follows.
1. If the machine is heavily unbalanced the spin sequence restarts and the process can
continue for up to 12 attempts if still very unbalanced then the cam position will
cause the drum to remain stationary for the remainder of spin time.
2. The machine also monitors the load at 650 rpm if still slightly unbalanced at this
point it will try three times to even the load; if it fails, the machine will carry on
spinning at 650 rpm until the end of the program.
3If the drum is not out of balance the module allows the machine to spin as shown in
the graph below.
