For safety reasons, it is vital that the EMERGENCY STOP button on the
control panel is actuated at least once a week. It must be estab-lished
when pressing the EMERGENCY STOP button that the circuit has been
interrupted.
With the wireless variant, this EMERGENCY STOP button test needs to be
carried out at both the control panel and base station.
