9.8.2 Checking the switching cycles
The system monitors the usage times of safety-relevant components to ensure the proper
condition of all safety-relevant functions. Depending on the component, the usage time may
be defined by run time or switching cycles. For the main contactor, the usage time is defined
by the maximum permissible number of switching cycles.
The main contactor switching cycle counter in SIGMA CONTROL 2 records the number of
switching cycles and generates a warning message when the maximum permissible number
of switching cycles is exceeded.
When this warning message is generated, the safety-relevant function is no longer ensured.
The main contactor must be replaced!
➤ Follow all instructions carefully.
