6.  Function

The safety system consists of three components:

 

Ì

Coded actuator 

 

Ì

Read head

 

Ì

Evaluation unit

1 read head can be connected to the evaluation unit.
The read heads and actuators are assigned to the device in a special teach-in operation.
Each delivered actuator possesses a unique electronic coding and so is a unique element in the system used. The code in 

an actuator cannot be reprogrammed.
The read head is fastened to the fixed part of the safety guard and is connected to the evaluation unit via a two-core screened 

cable (terminals H11, H12 and SH1).
The actuator fastened to the movable part of the safety guard is moved towards the read head by closing the door. When the 

switch-on distance is reached, power is supplied to the actuator by the read head by induction and data can be transferred. 

The read code is compared with the taught-in code in the evaluation unit.
If all data for match, the door monitoring output OUT (semiconductor output) is set to HIGH and the safety outputs (relay 

output) are enabled. The OUT LED illuminates.
Due to the combination of dynamic polling of the actuators and the redundant, diverse design of the safety electronics with 

redundantly controlled safety outputs, the evaluation unit will enter the safe state with every detectable fault.
When a safety guard is opened, the safety outputs switch off the safety circuit and the OUT LED goes out. The state of the 

safety outputs is monitored internally by positively driven NC contacts (relay output). 
Independent of the switching state of the safety circuit, the position of the safety door can be polled via the output OUT.
If an internal fault occurs in the evaluation unit, the safety circuit is switched off, the diagnostic output (ERR) is set HIGH 

and the ERROR LED illuminates red.
The safety contacts on the safety switch CES can also switch small currents. This allows the user to connect the device 

directly to a safe control system.
