The delay times set at the factory can be changed by the customer using the closed-loop
controllers. Change the settings of the time relay -K120 only when it is disconnected from the
power supply.
When you plan your settings, you must comply with the following rules:
T
delay K110
*T
tolerance
If this rule is not observed, safety is not restricted in any way. However, the second switch-off
signal path via the circuit-breaker is used for each activation.
