Figure E
– Mute Modules Showing Mute Beam Arrangements
Figure E shows the cross-beam muting for entry/exit and exit only applications.
The Receiver head which has the status indication LEDs and the B (User) cable
connection back to the machine control panel/local junction box is located to the
left side of the conveyor when looking towards the danger area. The Receiver
head has the status LED indicators which are useful during installation, for status
checking during normal operation and diagnostics for fault finding.
Entry and Entry/Exit
‘T’
087- 008 (Type 2)
Inverted ‘T’ shape cross-beam muting at in-feed zones or in situations where a
pallet load may need to pass along the conveyor in both directions through the
safety light curtain.
This system is normally used at the infeed to a machine. The horizontal mute
modules house the muting beams transmitting diagonally across to the receiver
side forming a cross-beam muting arrangement.
The system works by the pallet load moving into the two mute beams and
interrupting them. The two mute beams are monitored with a disparity timer of 2.5
seconds.
The cross-beam entry system has a no time delay-off as default. Therefore, if one
of the mute beams is remade or the load is out of the cross-beam mutes the
safety light curtain will unmute at once.
