摘要 |
<p>An operational check of the safety unit or the safety circuit takes place within the delay time of the relay, assigned to each motor, caused by the pick-up delay or the release delay. Also, the control unit can be equipped such with at least one safety component and/or safety circuit for controlling the control unit that an operational check of the control unit takes place between the operation of an operating element of the hand switch and the starting of the motor or motors. The operating time and the release time of the relay may be delayed by a suitable component so that sufficient time is available for the operational check.</p> |
