5 Operation
5.1 Obligations of the operator
The functionality of the safety module CAMC-G-S3 is to be checked at adequate intervals. It is the re­
sponsibility of the operator to choose the type of check and time intervals in the specified time period.
The check is to be conducted such that flawless functioning of the safety device can be verified in inter­
action with all components.
Proof test interval è Appendix A, Tab. A.1.
Warning
Danger of the failure of the safety function!
If there is a voltage failure, the safety functions are no longer guaranteed (exception:
Safe Torque Off, STO; Safe Brake Control, SBC).
A failure of the safety function can result in serious, irreversible injuries, e.g. due to
uncontrolled movements of the connected actuator equipment.
• Ensure that your application has a reliable voltage supply or provide other appropri­
ate measures.
5.2 Maintenance and care
The safety module does not require any maintenance.
5.3 Protective functions
5.3.1 Supply - Overvoltage and reverse polarity protection voltage monitoring
The 24 V power supply comes from the basic unit. The approved operating voltage range is monitored
by the safety module.
In addition, the power supply of the safety module is specially protected against
– Surges in accordance with EN 61326-3-1.
– A rise in the 24 V supply to up to 60 V in case of error (specification of the PELV supply).
Reverse polarity protection is provided by the basic unit.
5.3.2 Power supply for the internal electronics
The internal operating voltages are generated from the 24 V supply.
The internal electronic supply voltages are provided redundantly.
This means that the two microcontrollers in the safety module are powered independently.
They alternately monitor all the internal operating voltages.
