The checkback contacts of the safety relay are capable of at least
100,000 switching cycles at the specified load (30 V DC / 1 A). The
mechanical service life is about 10
an important component in ensuring reliability and availability of the
machine. For this reason, the pcb with the safety relay must be
replaced in the case of malfunction. In this case, the unit must be
returned for repair or replaced. Function checks must be carried out at
regular intervals, which must be defined in compliance with Employer's
Liability Insurance Regulation BGV A1 §39, para. 3. Accordingly,
function checks must be performed as required by the relevant service
