NOTICE
LEARN TO USE SMARTPAC PRO BEFORE INSTALLING ON A PRESS
If you have not used SmartPAC PRO before, learn how to initialize and program it before installing
it on a press. On the bench, connect your unit to a resolver (see page 24) and to AC power (see
page 25) so that you can access all the menus and make settings. See Chapter 1 for instructions
on using the touch screen and displays, Chapter 3 for using Initialization mode, Chapter 4 for using
Program mode, and Chapter 5 for using Run mode.
Installation Guidelines
Observe the following guidelines when installing SmartPAC PRO:
•
Separate high- and low-voltage wires
Never run wires for 120V and for lower voltages (e.g., 24V, 60V) inside the same conduit. Run
flexible, liquid-tight conduit for high voltage lines (120V power, input check circuit, stop relay
circuits) to the upper right-hand corner of the SmartPAC PRO enclosure. Run one or two low
voltage conduits for the resolver and communications control wires into the lower left- hand
corner of SmartPAC PRO. If you have top-stop and emergency-stop circuits that are 24V or a
voltage other than 120V, you must run them separately from the high-voltage wiring.
Never use the SmartPAC PRO power terminals as a junction point to provide power for external
devices. In most cases, the AC power supply wires should be connected directly to the press
control cabinet. Do not use the ProCam output enclosure as a junction box for the AC control
wires. Provide a separate junction box for this purpose.
Communications wiring should be run separately in its own conduit. Communications wiring will
be installed if SmartPAC PRO is connected to the WPC 2000 Wintriss Clutch/ Brake Control,
ServoFeed Interface (SFI™), AutoSetPAC, SBR, LETS/SFC, or other equipment.
•
Provide NEMA 12 conduit and connections
Because SmartPAC PRO is rated NEMA 12 (i.e., protected against dust and oil), you must use
conduit of the same rating and make proper connections to ensure that the enclosure is NEMA-
12-protected.
•
Properly ground SmartPAC PRO
The ground wire from SmartPAC PRO should be connected to the main ground point of the press
control system. This ground point may be in the area where the control transformer is grounded.
Finding a good place for a ground is sometimes difficult, but the location should be close to
where the press receives its ground.
•
Correctly terminate all cable shields
Terminate all cable shields to the studs provided in the enclosure or to a good grounding location
(see
Terminating Cable Shields , page 18).
•
Install suppressors across inductive loads
All relays, solenoids, or other inductive loads that are controlled by SmartPAC PRO must be
suppressed. Suppressors should be installed across the load and as close to the load as possible.
See Figure 2-12, page 39. Never install a suppressor across relay contacts. If you do, the
