11.2.1. Actuator teach-in
1. Establish teach-in standby:
- Devices in the condition as supplied: unlimited teach-in standby after switching on
- Switch already taught in: teach-in standby is available for approx. 3 min after switching on
¨ Teach-in standby indication, STATE LED ashes 3x repeatedly
2. Insert the actuator during teach-in standby.
¨ The automatic teach-in operation starts (duration approx. 30 s).
During the teach-in operation the STATE LED ashes (approx. 1Hz).
Alternate ashing of the STATE and DIA LEDs acknowledges the successful teach-in operation.
Teach-in errors are indicated by the illumination of the red DIA LED and a ashing code on the green State LED (see
chapter 12. System status table on page 32).
3. Switch off operating voltage UB (min. 3s).
¨ The code of the actuator that was just taught in is activated in the safety switch.
4. Switch on operating voltage UB.
¨ The device operates normally.
11.2.2. Teach-in function with series connection, replacing and teaching in device
It is recommended not to teach in the actuators in the series connection but to teach them in one by one instead. Teach-in
in a series connection works analogously to separate operation in principle. It is a prerequisite that the steps below are
followed. Further steps might have to be observed for mixed switch chains (e.g. for chains with CES and CET). Observe the
operating instructions for the other devices in the chain for this purpose.
Work on the wiring (e.g. during device replacement) should generally be performed in a de-energized state. On certain
systems, it is nevertheless necessary to perform this work and subsequent teach-in during ongoing operation.
Input RST must be connected as shown in Figure 5 on page 25 to permit this.
Proceed as follows:
1. Open the guard on which the switch or actuator is to be replaced.
2. Mount the new switch or actuator and prepare it for the teach-in operation (see chapter 11.2.1. Actuator teach‑in on
page 30).
3. Close all guards in the chain and activate guard locking.
4. Actuate the reset for at least 3s (24V on RST).
¨ On the safety switch that is positioned at a new actuator, the green LED ashes at approx. 1Hz and the actuator is
taught in. This takes approx. 30s. Do not switch off during this time and do not actuate reset! The teach-in operation is
complete when the STATE and DIA LEDs ash alternately.
5. Actuate the reset for at least 3s (24V on RST).
¨ The system restarts and then continues to function in normal operation.
