5 Actuator coding and latching force adjustment
5.1 Actuator coding
Solenoid interlocks with standard coding are ready to use upon delivery.
Individually coded solenoid interlocks and actuators will require the following "teach-in" procedure:
1. Switch the solenoid interlock's voltage supply off and back on.
2. Introduce the actuator in the detection range. The teach-in procedure is signalled at the solenoid interlock, green
LED off, red LED on, yellow LED flashes (1 Hz).
3. After 10 seconds, brief yellow cyclic flashes (3 Hz) request the switch-off of the operating voltage of the solenoid
interlock. (If the voltage is not switched off within 5 minutes, the solenoid interlock cancels the "teach-in"
procedure and signals a false actuator by 5 red flashes).
4. Once the operating voltage is switched back on, the actuator must be detected once more in order to activate
the actuator code that has been taught in. In this way, the activated code is definitively saved!
For ordering suffix -I1, the executed allocation of safety switchgear and actuator is irreversible.
For ordering suffix -I2, the "teach-in" procedure for a new actuator can be repeated an unlimited number of times.
When a new actuator is taught, the code, which was applicable until that moment, becomes invalid. Subsequent to
that, an enabling inhibit will be active for ten minutes, thus providing for an increased protection against tampering.
The green LED will flash until the expiration of the time of the enabling inhibit and the detection of the new actuator. In
case of power failure during the lapse of time, the 10-minutes tampering protection time will restart.
5.2 Latching force adjustment
In order to enable trouble-free functionality of the device, the rotary handle must be in position I or II when the safety
guard is open. In the intermediate positions, locking is impossible. The latching force is changed by turning the rotary
handle by 180°.
In position I,the latching force is approx. 25 N.
In position II, the latching force is approx. 50 N.
