Wire breakage and overtensioning

Please note the following with respect to wire breakage and overtensioning:
1. If the wire is pulled too hard and breaks, the signal lamp on cable-operated switches with
LED lights up red.
2. The indicator arrow for the operating cam points to the left on all cable-operated switches.
3. If the wire is overtensioned, the indicator arrow points to the right and the switch opens.
4. A reset is triggered and the arrow points to the left.
5. A manual reset can be initiated by actuation of the blue reset button.
6. On cable-operated switches with EMERGENCY STOP function, an emergency stop is initiated
when the red button is actuated.
Note
In the case of cable-operated switches with latching, contacts 21-22 and 41-42 are latched in
the open state and contacts 13-14 and 33-34 are latched in the closed state if the wire is
pulled or broken. The contacts can be unlatched by means of the button. The contacts can be
unlatched only in the mid-position, i.e. in the pretensioned position.
