SmartPAC 2 with WPC Integration
See "Press Parameters," page 229 in Chapter 4 to set the clutch and counterbalance air
pressure values.
NOTICE
IF YOU USE RAMPAC TO CONTROL COUNTERBALANCE PRESSURE
If you use RamPAC to control the counterbalance pressure, install a pressure switch and
connect it to WPC as described in the next section.
Clutch Air Pressure Switch
NOTICE
The clutch air pressure switch is held closed when the pressure is above the setpoint limit.
1. Install a filter regulator and lubricator in-line before the clutch air pressure switch, if not
already present.
2. Connect shop air to the clutch air pressure switch input port.
3. Run the cable through flexible, liquid-tight conduit as noted above (NEMA 12).
4. Connect the wires: For the clutch air pressure switch, refer to wiring diagram Figure 3 at
the end of the manual. Wire the normally open terminals of the switch between WPC
terminal #8 and ground (terminal #10).
5. Set the clutch air pressure switch for 35 PSI, or the pressure recommended by the press
manufacturer.
Counterbalance Air Pressure Switch
NOTICE
The counterbalance air pressure switch is held closed when the pressure is above the
setpoint limit.
1. Install a filter regulator and lubricator in-line before the counterbalance air pressure
switch, if not already present.
2. Connect shop air to the counterbalance air pressure switch input port.
3. Run the cable through flexible, liquid-tight conduit as noted above (NEMA 12).
