Replace Euchner CES Door Switches

Description: Replacing an Euchner CES-AR-C01-AH or actuator with a device of the same type

Slotted screwdriver

Non-contact safety system CES-AR-C01-AH:

Info: Before the system can form a functional unit, the actuator must be assigned to the safety switch via a teach-in function.

During a teach-in operation, the safety outputs and the monitoring output OUT are switched off, i.e. the system is in the safe state.

NOTE:

The evaluation unit detects only taught-in actuators (transponders). Only the last actuator to be taught in is detected. New actuators are taught in by installing a line bypass. This must then be removed again. When a new actuator is taught, the safety switch disables the code of its predecessor. This cannot be immediately re-taught in a new teach-in process. The disabled code is only released again in the safety switch after a third code has been taught.

IMPORTANT!

The safety switch disables the code of the previous actuator if teach-in is carried out for a new actuator. Teach-in is not possible again immediately for this actuator if a new teach-in operation is carried out. The disabled code is released again in the safety switch only after a third code has been taught. The safety switch can only be operated with the last actuator taught. If the switch detects the actuator that was most recently taught when in teach-in standby state, this state is ended immediately and the switch changes to normal state. The actuator being taught is not activated if it is within the operating distance for less than 60 s.

Preparing the device for the teach-in-process:

1. Connect the switch but do not apply voltage to UB. Alternatively, turn off the main switch.
2. For ready-to-teach, the teach-in input J must rewired from 0 V to 24 V DC. Please note: For normal operation reconnect the teach-in input to 0 V.

In our case, this means setting a jumper. Caution: Refer to the circuit diagram at this point! The circuit diagram describes or shows where the jumper needs to be set! In addition, you can also see what the abbreviations UB, J, etc., stand for!

Teach-in function for actuator:

The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.

During a teach-in operation, the safety outputs and the monitoring output OUT are switched off, i.e. the system is in the safe state.

Teaching an Actuator

1. Apply operating voltage to the safety switch.

   The green LED flashes quickly (approx. 10 Hz).

   A self-test is carried out during this time (approx. 0.5 s). The green LED then flashes cyclically three times and signals that it is in standby state for teach-in.

   Standby state is kept for about 3 minutes. If the red LED lights up, an error has occurred. Teach-in is not possible.

2. Move new actuator to the read head (observe distance < *Sao). *Assured switch-on distance

3. The teach-in process starts; the green LED flashes (approx. 1 Hz).During teach-in, the safety switch checks whether the actuator is a disabled actuator. If this isnot the case, the teach-in operation is completed after approx. 60 seconds, the green LED goes out.

   The new code has been saved, the old code disabled.

4. To activate the new actuator code from the teach-in operation in the safety switch, the operating voltage to the safety switch must then be switched off for min. 3 seconds.

5. Remove the jumper that you set.

6. Switch on the supply voltage, UB. Alternatively, turn on the main switch again.

7. Check whether everything works.
