Override
The override function enables you to bridge the muting
sequence and thus clear, for example, the jammed trans-
ported material. Override is only possible if the function
block LM has detected an error in the muting sequence. In
order to activate override, you must set a maximum override
release time RT. When the coil LM..OV picks up, the muting
sequence is bridged and the enable is initiated at function
block output LM..QS. The override is terminated after the
override release time RT has elapsed or the coil LM..OV is
opened. The override function is also terminated if the
muting system detects the default state. This is the case
when no muting sensors have been triggered and the light
curtain is clear.
If the function block has the Manual Start (MST) or
Controlled Start (CST) operating mode, the LM..RE reset
input must be activated in order to reset the function block
and start uninterrupted operation.
h
Install the override pushbutton in a location with a clear
view of the hazardous zone.
The override function must only be executed by authorised
personnel and should only be activated using something
like a key switch.
