HIGH THROUGHPUT CONVEYOR (HTC)
Introduction
Figure 34-30 HTC Controller Location
The HTC controller (M27) enclosure is located behind the front maintenance
cover just below the mains isolator switch.
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.
On machine initialisation, each auxiliary conveyor PLC needs to detect the
machine ’System Power’ and a ’Downline Available’ signal before the system
starts operating. If the machine is being run in a stand-alone environment, 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.

Operation The 1/3 Stage Operation and Fast Transfers Disabled buttons are LED illumi-
nated push buttons and are configured as follows:
3-Stage/Single
Stage Mode
For 3-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 Transfer 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 Transfer Disabled
buttons must be ON (LED lit). Normal transfer mode is not displayed on the
PLC.

MACHINE PERFORMANCE
Carry out a machine capability check and compare the results with the check
completed prior to transportation.
Machine Capability Load the product file named 265test1 from the hard disk and with a DEK
alignment board loaded ensure that the following parameters are correct:
• Screen - Calibration/Dry Align
• Squeegee - Length to suit board / ProFlow - Empty Transfer Head
• Front & Rear Print Speed - 25mm/sec (squeegees) / 70mm/sec (ProFlow)
• Front & Rear Pressure - 5kg (squeegees) / 3kg (ProFlow)
• ProFlow Paste Pressure - 2.0 bar
• ProFlow Idle Pressure - 0.2 bar (ProFlow with SCAR)
• Separation Speed - 1mm/sec.
• Under Board Clearance - 20mm
• Paste Dispense - 0
• Under Screen Rate - 0
• Transport Mode - Left to Left
• SPC Data Output Rate - Every Cycle
• SPC Data Mode - Disk
• SPC Format - Windows
• SPC Align Inspect Mode - Pre & Post Print
Use nine magnetic tooling pins to fully support the board, apply a small amount
of paste or suitable lubricant (enough to lubricate squeegees). Record >100 full
machine cycles and setup QC-Cal program as follows:
1. Start the QC-Cal program.
2. Select Statistics, Cpk - Process Capability.
