5 Operation
5.1 Obligations of the operator
The operational capability of the safety equipment must be checked at adequate intervals. It is the
responsibility of the operator to choose the type of check and time intervals in the specified time
period. The check must be made in a way that proves proper functioning of the safety equipment in
interaction with all components.
5.2 Maintenance and care
The safety module does not require any maintenance.
5.3 Protective functions
5.3.1 Voltage monitoring
The input voltages at STO-A and STO-B are monitored. If the input voltage at STO-A or STO-B is too high
or too low, the driver supply for the power semiconductors of the motor controller are safely switched
off. The power output stage (PWM) is thus switched off.
5.3.2 Protection against overvoltage and reverse polarity
The control inputs STO-A and STO-B are protected against overvoltage and reverse polarity of the con­
trol voltage

The 24 V DC supply voltage for the motor controller routed to [X40] is short-circuit resistant.
