7 Override
This function makes it possible to bypass the barrier completely and activate the OSSD outputs if
machine start is necessary even if one or more beams are interrupted.
This possibility is included in all Focus II barriers. This function is only possible when the muting
indicator is connected and if at least one beam is interrupted. If e.g. a pallet during muting operation has
stopped and at least one beam is interrupted after a voltage drop out, it would otherwise not be possible
to restart the conveyor belt.
NB! Make sure that the operator is able to check the entire protective f ield as long as override function is
enabled. Failure to do so may result in serious injury.
To start override, the Focus II must be in stop state and at least one beam must be blocked.
If the entire protective f ield is free for more than 2 s the override function is immediately stopped.
A Test request on the TEST/RESET input will stop the override function immediately.
Maximum timeout for override is 600 s. After this timeout, the Focus II system is restarting according to
the interlock mode set by the selector switches.
At start-up:
Switch off the power supply.
Restore the power supply and press the test/reset (see 5) button after approx. 2 s but within 5 s and
keep the button pressed for at least 5 s. The OSSD outputs will activate and thereby remain activated
for a maximum time of 600 s.
The override function is now enabled and the LMS indicator ashes to signal that the barrier is being
overridden.
At automatic reset, the OSSD outputs remain activated.
At manual reset, the reset button must be pressed and released again.
At operating cycle:
One or both muting inputs must be active.
Press and release the test/reset (see 5) button 3 times <1 s. The OSSD outputs will be activated for
>2 s.
