When installing a Smartscan 5K8 Series light curtain your attention is drawn to
the following: (
Figure F
)
The inverted T 5K8 series light curtain is also known as an entry/exit system.
This system is normally used between two zones (machines) allowing transfer
of the pallets from one zone to the other. The horizontal mute module
provides 2 muting beams at either end of the mute module transmitting infra
red mute beams diagonally across to the receiver side forming a cross beam
muting arrangement.
The system works by the square pallet load moving into the two mute beams
and interrupting them. The two mute beams are monitored with a disparity
timer of two seconds to provide a mute initiation of the light curtain.
The L shaped 5K8 series light curtain is also known as the exit only system.
There are two types of ‘L’ available, right hand (L1) and left hand (L2). The Left
or right hand indicates where the User B cable is connected as shown above.
You will note that the mute cross beams are arranged on one side of the light
curtain. They function in the same format as the T shape explained above.
The cross beams must always be on the Danger side and therefore the pallet
can only travel in one direction moving away from the danger to the safe side
of the machine.
It is a control requirement for the 5K8 series that an additional 3
rd
mute input is
provided via the conveyor run signal. This signal acts as a permissive signal
to the cross beam mutes and/or external mute input signals.
