Machine Areas
8.1
Introduction
During this section of the training, we review the different areas of the machine,
and the key set up procedures for each area. See Section 7.4 in the Service
Manual for the location of components.
The Axis Calibration of the PSQ is critical to the quality of the books it will
produce. Performing these procedures ensures all of the sub-assemblies are in
correct alignment to each other.
Note:
Areas marked with red paint are Factory Settings only. You must not
change this setting unless instructed to do so as part of a Call Escalation.
8.2
Connecting Bridge
The paper transport belts are driven by a brushless 3-phase motor with dedi-
cated controller. The rotate axis is adjusted by a 24V DC Axis Motor.
The Bridge Drive motor runs when the PSQ starts.
The sheets are transported under 2 Optical Sensors. The first Optical Sensor is
located at the Bridge Infeed, and the second Optical Sensor is located at the
entrance to the Gathering Area.
If the time between the sheets passing under the Bridge Infeed Sensor to the
Gathering Area Flow Sensor is more than a pre-calculated time, a jam will be
indicated.
Locate the following in the Connecting Bridge (Top):
Uplift cover switch
DFA Interface PCB (900-218)
Rotate Axis Motor Control PCB (900-212)
DFA Connect PCB (900-284)
Locate the following in the Connecting Bridge (Bottom):
Bridge Infeed Optical Sensor
Rotate Axis Home Switch
Rotate Axis Motor
Bridge Drive Motor
Minas bridge Motor I/F PCB (900-270)
Minas motor controller
Perform the following tasks:
ADJ 4.4.1 (Calibrate the Rotate Axis)
6.19.2 (Manual Operation of Machine Axes from Axis Control PCBs)
