Sensor power supply
For the sensor supply, please ensure that the maximum current consumption does not exceed
250 mA and the parameter Diag TestPulse active is set to FALSE.
Configurable inputs
The inputs 1 to 8 can be occupied as you want with normally closed contacts or normally open contacts.
The corresponding evaluation takes place in the safety controller.
Alternatively, a safe sensor can be supplied with 24 V
contacts. The polarity of pins 1 and 3 can be parameterized. Detection of cross-circuits or external feeds
must take place via the connected safe sensor.
Functional earth
Pin 5 of the M12 connections is not connected to the functional ground, since an SELV/PELV power
supply unit is specified for the EtherCAT Box.
