3.6 Operating modes
The DIP switches in the connector cover enable the following operating modes to be
selected:
- Safety mode with / without restart interlock
- With / without contactor check
- equivalent / antivalent outputs (Fig. 9/1)
In the condition when delivered, the preset operating mode comprises safety mode with
restart interlock, contactor check and equivalent outputs.
The following operating modes can be set:
Caution!
The operating mode may only be selected when no voltage is present. If the DIP switches are actuated during
operation, the light barrier will switch off the outputs and go to locking status. This is indicated by flashing of the
yellow and orange LEDs. Locking status will only be ended once the power supply has been switched off.
The switchgears ULSG, LSUW NSR 3-1-K and LSUW N1-Muting K are available for additional functions such as potential-free
output contacts or muting (Refer to Section 7 for further information and electric connection).

Without contactor check
With contactor check
The operating mode with contactor check serves to monitor the
driven succeeding contactors.
After each interruption of the light path and before each release of
the switching outputs, it is checked whether the succeeding
contactors have fallen. Only then will a new release be possible. If
the contactors do not respond within 300 ms, the light barrier
switches off the outputs and goes into locking status.
Without restart interlock
With restart interlock
With the operating mode with restart interlock selected, a button
must be connected to the start button input for a start release of the
operating movement.
When the protective field is free, the yellow LED lights up on the
receiver as a start prompt. Only once the start button has been
pressed will the outputs of the ULVT be switched to active.
Equivalent outputs
Antivalent outputs
In the equivalent outputs operating mode, both PNP outputs are
failsafe and monitored internally for short-circuits and cross-circuits.
With a free light path, both outputs are high (+24 V). In the antiva-
lent outputs operating mode, output 1 is high (+24 V) and output 2
low (0 V) when the light path is free. Output 2 is not failsafe in this
operating mode. This operating mode is only permissible in
conjunction with the safety switchgears LSUW NSR 3-1K, LSUW
N1-Muting K, or another safe sequential phase control device which
monitors output 2!
