With hard-wired LEDs the following applies:
-LED1: red = Solenoid activated (voltage present at solenoid)
-LED2: green = OUT D is switched on (door is closed)
Ì
Depending on version, the function of LED 1 and LED 2 can differ. Detailed information is available
on the enclosed data sheet or at www.euchner.com. Simply enter the order number in the search
box.
11.2. Teach-in function for actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.
During a teach-in operation, the safety outputs and the monitoring output OUT are switched off, i.e. the system is in the
safe state.
Depending on the version, the teach-in operation is automatic or is undertaken with the aid of the teach-in input J.
Tip!
We recommend performing the teach-in operation prior to mounting. Mark switches and actuators that
belong together in order to avoid confusion.
Important!
Ì
The teach-in operation may be performed only if the device functions flawlessly. The red DIA LED
must not be illuminated.
Ì
The safety switch disables the code of the previous actuator if teach-in is carried out for a new
actuator. Teach-in is not possible again immediately for this actuator if a new teach-in operation is
carried out. The disabled code is released again in the safety switch only after a third code has
been taught in.
Ì
The safety switch can be operated only with the last actuator taught in.
Ì
Version without teach-in input: After starting, the device remains in teach-in standby state for
3 min. If no new actuator is detected in this time, the device changes to normal operation. If the
switch detects the actuator that was most recently taught in when in the teach-in standby state,
this state is ended immediately and the switch changes to normal operation.
Ì
Versions with teach-in input: Teach-in operation ends when the power supply to the teach-in input is
interrupted, but no later than after 3 min. If no actuator was detected during this time, the device
enters the fault state.
Ì
The actuator to be taught in is not activated if it is within the operating distance for less than 60 s.
