Function: When the emergency stop switch is actuated, the motor is stopped according to stop category 0 of EN 60204-1.
When the operation mode selector is actuated, the safely limited speed is activated.
When the lower light curtain is interrupted, it is monitored that the positive direction is observed, i. e. the negative direction is impeded.
When the upper light curtain is interrupted, the safe operating stop is activated.
The motor contactor and the operation mode selector must be equipped with positively driven contacts.
If the current consumption of the contactor coil exceeds 500 mA, both channels of the safe output must be connected in parallel using decoupling diodes. If only O1A is used, you need not use any decoupling diode.
The current consumption must not exceed the value of 500 mA per channel specified in the Manual (i. e. 1 A in case of a parallel connection of O1A and O1B)
The application example implements an emergency stop according to EN 60204-1.
Only use the application example if an automatic electrical isolation between mains and motor is absolutely necessary.
