control the distribution of compressed air to the conveyor board stops.
Rail width adjustment is achieved by manually adjusting the position of the
moving rail along the conveyor guide shafts on the two bearing blocks. The rail
is secured in position by the locking thumbscrew on right hand bearing block.
Left Hand Conveyor The left hand auxiliary conveyor can be configured from the machine’s upline
conveyor to the downline conveyor, by the addition of the conveyor board stop
at the end of the conveyor rail. Also, the auxiliary conveyor sensor is moved
from it’s inboard position as the upline auxiliary sensor outboard as the downline
auxiliary sensor.
Each of the conveyor’s rails house a transport belt motor driving one of two belt
pulleys on the front face of the rail.
A single pneumatic solenoid valve, type 5/2 is fitted to the fixed rail support to
control the distribution of compressed air to the conveyor board stop.

High Throughput
Conveyor
Controller (M27)
The 3-Stage conveyor controller (M27) enclosure is located at the rear of the
machine above the ac power supply module (M23).
The M27 consists of a Programmable Logic Controller (PLC) for each auxiliary
conveyor. Above each PLC are the switches for selecting between 3-Stage/
single stage and fast/normal mode (Stage Conveyor Controller (M27) figure
refers).
On machine initialisation, each auxiliary conveyor PLC needs to detect the
machine ‘System Power’ and an initial ‘Downline Available’ signals before the
system starts operating. If the machine is being run in a stand-alone environ-
ment, the ‘Downline Available’ signal from the downline machine can be mim-
icked by shorting pins 1 & 2 of loom Pt No 160645 to the downline machine.

3-Stage/Single
Stage Mode
For three stage mode, both 1/3 Stage Operation buttons must be OFF (LED
extinguished). The LCD screen on the PLC displays ‘3 Stage’ on the top line.
For single stage mode, both 1/3 Stage Operation buttons must be ON (LED lit).
The LCD screen on the PLC displays ‘1 Stage’ on the top line.

Fast/Normal Mode For a conveyor to operate in fast transfer mode, both Fast Transfers Disabled
buttons must be OFF (LED extinguished). The LCD screen on the PLC displays
‘Fst.Trans.’ on the bottom line for 5 seconds on power up or when the button
is switched to OFF.
For a conveyor to operate in normal transfer mode, both Fast Transfers
Disabled buttons must be ON (LED lit). Normal transfer mode is not displayed
on the PLC.
