Description Of Operation (Antirepeat Device):
An antirepeat device is fitted to prevent the hydraulic control unit from overheating.
The total motor running time of the hydraulic control unit is recorded by a counter. If the motor is not activated, this counter is reduced by a third of the pause time. If the counter exceeds a total running time of 2 minutes, no further actuations are accepted. Thus, for a motor running time exceeding 2 minutes, an enforced pause which is three times as long is engaged.
After a cooling-down period of 6 minutes, it is again possible for the motor to run for 2 minutes.
NOTE:
However, an actuation which is in operation is not terminated even if the maximum running time is exceeded.
