In the Emergency stop or LC functions, both signals have to change from
inactive state into active state within 250 ms. If the second signal reacts
later, both changeover contacts must turn inactive before they can be
enabled again.
With manual start, all safety inputs must be active before the start button
can be pressed to trigger enabling. To start the system, do not keep the
start button pressed for more than 3 seconds. A module may also be
assigned several start buttons.
Note:
Connect only self-testing light curtains of the type 4 acc. to
EN 61496 to the module. Short-circuit monitoring of the inputs
for the LC must be done in the LC.
Function errors are indicated by the white LED Run 1 and by output 48;
the white LED Run 2 remains on. Output 58 is ON as long as the error is
pending; it flashes regularly, while waiting for the assigned start signal.
Error codes*
1) Normal interruption of function (e.g. Emergency stop)
2) Time error: (e.g. the second two-hand button is not pressed)
3) With gate monitoring: simulation input error (kept pressed for
too long)
4) Error at start input
5) Input error (short-circuit, interruption)
6) Error in the control unit (input or output error detected in
the control unit)
* number of short flashing impulses, followed by a longer space
Special with two-hand control:
When both two-hand buttons of the module are inactive while all other
functions are active and enabled either by autostart or via the start button,
output 48 and the white LED Run 1 are permanently OFF, and output 58
permanently ON.
Special behaviour on e-stop (function setting 2 or 3):
Initial state: all e-stop buttons are not activated and the start button has
been pressed correctly on manual start. An other module gives no enabling
signal independent of the assigned output module. Output 48 and the
white run LED 1 are off and output 58 is continuously on.
In this state the module will give the enabling signal automatically as soon
as all other modules give their enabling signals together.

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.
Error codes*
0) (both white LEDs are off):
Another input module indicates a system error.
1) To 4): not used
5) Incorrect setting of function:
- The rotary switches for channel 1 and 2 has different or
incorrect positions
- The setting of the 4 upper Dip-switches (channel 1) are not
identically to the 4 lower Dip-switches (channel 2)
