E-Stop or Light Curtain (LC) Function

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 as-

signed 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.

Indication of System Errors:

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.

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)

Function Error Indication

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 but-

ton, output 48 and the white LED Run 1 are permanently OFF, and out-

put 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 en-

abling 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.
