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
mimicked 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.

Board Clamps A board clamping arrangement is utilized to secure the board during the print
process and to minimize board distortion. A pneumatically operated piston, (via
a 24V switched solenoid 16SOL10 from the machine controller), lowers the
board clamp and foil, trapping the board on the transport belts. On completion
of the print stroke the board is released by activation of the pneumatic solenoid.
An in-line pneumatic exhaust ensures quick release of the board clamps.
