Teach-in function for handle module (only ESL uni-
code)
The handle module must be assigned to the interlocking module using a teach-in
function before the system comprising interlocking module and handle module
forms a functional unit.
During a teach-in operation, the safety outputs are in high-resistance state, i.e. the
system is in the safe state.
When a handle module for which teach-in operation is possible is in the operating
distance, monitoring output OD indicates this with a HIGH signal.
Important!
Ì The interlocking 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 again in the interlocking module only after a
third code has been taught.
Ì The interlocking module can only be operated with the last handle module
taught.
Ì The interlocking module enters normal operation when it detects the taught
handle module after power up.
Ì If the interlocking module detects a disabled handle module during teach-in
operation, it enters a fault state at the end of the teach-in operation.
Ì If the closure is within the operating distance for less than 30 seconds, the han-
dle module is not taught in and the interlocking module enters the fault state.
Teaching in handle module
1. Fit handle module.
2. Close safety guard. Check for correct alignment and distance and readjust if
necessary.
3. Apply operating voltage to the interlocking module.
¨ The green LED flashes quickly (approx. 5 Hz)
A self-test is performed during this time (approx. 8 s). Teach-in operation
starts, green LED flashes slowly (approx. 1 Hz). The teach-in operation is
ended after approx. 30 seconds and is positively acknowledged with an al-
ternating red/green flashing sequence.
4. To activate the handle module's code from the teach-in operation in the interlock-
ing module, the operating voltage must then be switched off at the interlocking
module for min. 3 seconds. As an alternative, 24V can be applied to the input
RST for min. 3 seconds.
