10. Additional functions and additional modules
10.1. Timer module ASU2 (optional)
The timer module can be plugged onto the controller. Function: When the timer has
reached the set time for open, it sends an OPEN command to the controller. The gate
cannot be closed as long as the timer is activated. After the open time has elapsed, the
timer sends a CLOSE command to the controller.
Note: When the timer sends the CLOSE command, the gate is closed immediately, even
when automatic closure is activated.
10.2. Traffic light module AMO34A (optional)
Red and/or green traffic lights can be connected to the traffic light module.
