13. Commissioning
13.1. Teach-in operation (only for MGB unicode)
The handle module must be assigned to the locking module using a teach-in function before the system comprising locking
module and handle module forms a functional unit.
During a teach-in operation the safety outputs are switched off.
Important!
Ì The locking module disables the code for the previous handle module if teach-in is carried out for
a new handle module. Teach-in is not possible again immediately for this actuator if a new teach-in
operation is carried out. The disabled code is deleted in the locking module only after a third code
has been taught.
Ì The locking module can be operated only with the last handle module taught.
Ì If, in the teach-in standby state, the locking module detects the handle module taught-in or a
disabled handle module, the teach-in standby state is ended immediately and the locking module
changes to normal operation.
Ì If the bolt tongue is in the operating distance for less than 60 s, the handle module is not taught.
Tip!
A teach-in adapter is available to make it easier to teach-in AR devices already mounted in series or
for device replacement (order no. 122369). It is simply inserted between the connecting cable and
the AR device. The device immediately enters teach-in operation on reconnection. After teach-in, the
adapter is removed again and the MGB is connected normally.
Teaching in handle module
1. Fit handle module.
2. Close guard. Check for correct alignment and distance using the marking on the locking module and re-adjust if necessary.
3. Insert bolt tongue in the locking module.
4. Apply operating voltage to the locking module, optionally connect teach-in adapter.
¨ The green LED (State) ashes quickly (approx. 5 Hz). A self-test is performed during this time (approx. 10s in case of AR
conguration). Teach-in operation starts, green LED (State) ashes slowly (approx. 1 Hz). During the teach-in operation,
the locking module checks whether the handle module is a disabled handle module. Provided this is not the case, the
teach-in operation is completed after approx. 60 seconds, and the green LED (State) goes out. The new code has now
been stored, and the old code is disabled.
5. To activate the handle module's code from the teach-in operation in the locking module, the operating voltage must then
be switched off at the locking module for min. 3 seconds. As an alternative, 24V can be applied to the input RST for at
least 3 seconds.
Teach-in in a series connection works analogously. Here, the complete series connection must be restarted using the input RST.
13.2. Mechanical function test
It must be possible to insert the bolt tongue easily in the locking module. To check, close guard several times and actuate
door handle.
If available, check function of the escape release. With active guard locking it must be possible to operate the escape release
from the inside without excessive effort (approx. 40N).
