This module is intended for applications in which numerous one-channel
Emergency off contacts are to be monitored.
The settings 2, 3, 6, and 7 are required for example when several modules
are connected to a common Emergency stop sensor. Short-circuit reco-
gnition can be realized externally by means of proper wiring.
With a LC type 4 (according to IEC/EN 61496-1), short-circuit monitoring
takes place in the light curtain itself.
Note:
With single-channel safety inputs, safety function can only be realized
when voltfree contacts are used (see wiring examples).
With static, voltage signals, it is imperative to use 2-channel signal
sensors.
Automatic start is performed only when supply voltage is switched on, or
when enabling has been cancelled by pressing Emergency stop.
All other errors nevertheless require confirmation by a start key.
To start the system, do not keep the start key pressed for more than 3
seconds. A module may also be assigned several start keys.
Function errors are indicated by the white LED Run 1 and by output 48;
the white LED Run 2 remains on. Output 58 remains on as long as the
error is pending; it flashes regularly as soon as enabling via the assigned
start button is possible again:
Error codes*
1) Emergency stop
2) Time error: Start button has been kept pressed for more than 3 se-
conds
3) Time error: The 2 signals of the 2-channel Emergency stop fail to
correspond for too long (250 ms)
4) Error on start button (kept permanently pressed)
5) Input error (short-circuit, interruption)
6) Error in the control unit (input or output error recognized in the con-
trol unit)

These errors are indicated by flashing codes of the white LEDs Run 1 and/
or Run 2. The green LEDs and all outputs turn inactive. The system will
only restart after the supply voltage has been switched off and on again.
