Activate and Guard Override Functions
Manual Restart
- At power-up or, following a tripped condition, the activate
switch is used to restart (reset) the output relays to an ON state. The switch
must be activated and released to enable a restart condition.
The reset switch must be located so that the operator cannot reset the light
curtain from inside the dangerous area. In addition the reset switch must be
positioned so that the operator can see that the dangerous area is safe / free
of personnel before resetting the machine.
Guard Override
- This function should only be used when using the light
curtain to transfer pallet loads from one zone to another.
If the safety system trips when a
pallet load is interrupting the
sensing field of the light curtain
the safety system cannot be
restarted. In order to remove
the blockage from the light
curtain the 5K8 series provides
a guard override facility. This is
achieved by activating and
holding the guard override
switch until the blockage has
cleared the sensing field of the
light curtain. The maximum time
permitted for this is 3 minutes.
However if the time is
inadequate the process can be
repeated by simply releasing the
active switch and re-activating
and holding the switch again.
The guard override switch can
be a push button, preferably a
key switch of the type ‘spring
return’.
Please note that the light curtain’s safety outputs (OSSDs) can only be reset
once the light curtain sensing field is free of the obstruction. Therefore the
override function is only available whilst a pallet load is blocking the sensing
field of the light curtain.
The Restart controls must be located such that the danger area can be
seen to be clear of persons before the system is activated.
