WARNING: The entire machine safety system must
be tested at the start of every shift. Machine testing
should include: (1) proper machine operation and
stopping capability; and (2) verifi cation of proper
installation and settings of all point of operation
guards and devices before the operation is released
for production.
Important Notes
• When using step down or isolation transformers
make sure to ground one side to prevent the
Neutral from floating above ground and
causing the surge suppressors (MOV’s) to
short out.
• The resolver cable must be kept away from
high current and/or high voltage lines, or run
in its own conduit to prevent excessive noise
from causing nuisance faults to occur.
• All remotely wired switches, buttons, etc. must
use shielded cable and be kept away from
high current and/or high voltage to prevent
nuisance faults.
• If you use the +12VDC source on the I/O
board for die inputs, do not bring a wire from
the “GND” terminal out to your machine.
Simply connect the “GND” to the earth ground
and use the machine itself as the ground.
Resolver Mounting
The resolver may be driven directly through a Lovejoy
coupler, gear and chain, or timing belt.
If a chain or belt is used, it must be set for a 1:1 ratio.
CW or CCW rotation can be setup by changing the
lead confi guration. Bring the press up to top dead
center and set the new top dead center (see “Speed
Compensation” in Function Description section of this
manual for instructions).
Refer to Drawing #28-100 for Resolver Dimensions &
Wiring as well as Drawing #28-101 for Internal Wiring
at the end of this section.
Controller Mounting
Control Box Mount. If you purchased a PressCam 8 in
its own enclosure, then the I/O board is already mounted
inside the box so it is only necessary to fi nd a location
with good access and clearance to prevent the LCD from
being damaged from the door hitting nearby objects. If
the location has vibration, you must shock mount the
box to prevent damage.
System Installation
Four mounting holes are all that is necessary to mount
the box (see Drawing #28-102 for dimensional layout
and Drawing #28-101 for wiring diagram in this section).
Panel Mount. If you purchased a PressCam 8 without
its own enclosure then you must fi nd a location on
your control cabinet that will allow you to mount the I/O
board as close as possible to the PressCam 8 controller.
There is a 40 pin ribbon cable that connects both boards
together and must remain as short as possible to prevent
nuisance faults due to electrical noise getting into the
system through this cable. If the controller is to be on a
door, make sure that when the door is opened nothing
will come into contact with the LCD. Mounting the unit
closer to the hinge is probably a good idea. Cut out
a hole in your control cabinet and drill eight mounting
holes. Insert the PressCam 8 into the hole and install
the eight #6 keps nuts. Refer to Drawing #28-103 for
Panel Cut-Out Dimensions, Drawing #28-104 for Control
Panel Dimensions, and Drawing #28-101 for Internal
Wiring on the following pages.
I/O Board Mounting. If you are installing a panel mount
unit, then mount the I/O board as close as possible to
the panel mount controller. Dress the 40 pin ribbon
cable between the controller and the I/O board to fi nd
out how long the cable needs to be. Cut the excess
cable and crimp on the 40 pin connector making sure
the arrow on the connector points to the red lead of
the cable (just like the other end of the cable). Use an
arbor press, or similar, to squeeze both halves of the
connector around the cable. Be sure to keep the cable
straight while crimping, otherwise, the cable contacts
will be shorted. Refer to Drawing #28-104 for Control
Panel Dimensions and Drawing #28-101 for Internal
Wiring on the following pages.
Internal System Wiring
1. Assemble 40 pin cable and install between
control unit (P1) and I/O board (P1). Be sure
to watch for pin1.
2. Install resolver cable between resolver and
control unit (J11).
3. Install fi ve wire power cable and install between
I/O board (J9) and control board (J1).
4. Install tuning knob cable on J2 (left side) on
control board.
5. Install RUN/PROG key switch cable on J5 (right
side) on control board.
6. Install LCD cable to J14 on control board.
7. Install LCD inverter cable to J3 on control board.
