7.2.3
Teaching-in the new actuator
Overview
The TR110 Lock safety locking device can be operated only with the actuator that was
last taught-in.
Important information
NOTE
Safety locking devices with an actuator that has already been taught-in have a teach-in
readiness of approx. 3 minutes after being switched on.
NOTE
•
If the safety switch detects an actuator that has already been taught-in, then the
teach-in process is canceled and the safety switch returns to normal mode.
•
If the safety switch detects a blocked code of a direct predecessor actuator, then
the teach-in process is canceled and the code of the previous actuator remains
active. The safety switch goes into an error state (
).
Approach
1.
Apply the supply voltage to the safety switch.
✓
The STATE LED flashes 3 times repeatedly.
2.
Insert the actuator into the actuating head within 3 minutes.
3.
The teach-in process starts, the STATE LED flashes at approx. 1 Hz.
✓
The teach-in process is completed after about 30 seconds. The STATE and DIA
LEDs flash in alternation.
4.
Switch off the supply voltage at the safety switch for at least 3 seconds and then
switch it back on.
✓
This activates the new code and deactivates the old code.
5.
Check the effectiveness of the protective device.
Complementary information
When a new actuator is taught-in, the safety switch blocks the code of the last actuator.
The latter cannot be taught-in again immediately when a new teach-in operation is per‐
formed. The blocked code is released again in the safety switch only after a third code
has been taught-in.
7.2.4
Teaching-in the actuator in safe series connection
Important information
NOTE
It is recommended to teach in the actuators not in the safe series connection, but indi‐
vidually.
Prerequisites
If the actuators need to be taught-in in a safe series connection, then it has to be possi‐
ble to switch from 0 V DC to 24 V DC at the RST inputs of the safety switches.
