7.7 OVERRIDE
This function makes it
possible to override or bypass the system.
It
is used to start up the
machine
after the
material has interrupted one
or more
of the SLC beams and to free the protected area from any
material that is present in front of the SLC,
If a
pallet
has stopped in front of the protected area, it will not be
possible to restart the conveyor belt because the SLC detects one or
more beams have been interrupted and therefore will not close the
outputs; therefore the
protected area
cannot be cleared.
However, it can be cleared if the
override
function is enabled.
This function can be used for all SLCs with the
LMS muting indicator
connected, as described in section 3.
7.7.1 ENABLING THE OVERRIDE FUNCTION
•
Switch the appliance off.
•
Switch it on again and press the
test/restart
button within 5
seconds, keeping it pressed for at least 5 seconds.
•
The
override
function is now enabled. The
LMS muting
indicator
flashes to signal the exclusion of the SLC.
•
The maximum duration of the
override
function is 120 seconds,
after which the SLC is reset, even if the button is kept pressed.
Naturally, if the button is released before this, the
override
function will terminate immediately.
