2 Teach-in

2.1 Preparing device for teach-in operation

 Connect the CET as shown below, but do not apply any voltage to UB yet.

In case of version with teach-in input: For the teach-in standby state, the teach-input J must be reconnected from

0 V to +24 V DC. Important: In normal operation reconnect the teach-in input to 0 V.

In case of version without teach-in input: The circuit is the same, but connection J is omitted.

 Observe different control of guard locking for CET1/3 and CET2/4.

2.2 Actuator teach-in

1. Switch on operating voltage UB.

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

A self-test is performed during this time (approx. 8s). After this, the green LED flashes cyclically three times and

signals that it is in standby state for teach-in. Standby state for teach-in remains active for approx. 3 minutes.

 If the red LED is illuminated, there is a fault. Teach-in is not possible. The green LED indicates the fault code.

Diagnostics see section System status table on page 9.

2. Activate guard locking.

CET1/3: no voltage at UCM.

CET2/4: voltage at UCM.

3. Fully insert new actuator into the recess. Do not cant it; place it in the center of the recess (see picture below).

 Teach-in operation starts, green LED flashes (approx. 1Hz). The teach-in operation is completed after approx.

60 seconds and all the LEDs go out.

4. Switch off operating voltage UB (min. 3 seconds).

 The code of the actuator that was just taught in is activated in the safety switch.

5. In case of version with teach-in input: Connect teach-in input to 0V.

6. Switch on operating voltage UB.

 The device operates normally.
