SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Installation 2-15
5.
Set the counterbalance air pressure sensor to the pressure recommended by the press
manufacturer, typically the pressure required for the smallest upper die you plan to use in
this press
Installing a Clutch Air Pressure Switch
Install and wire the clutch air pressure switch as follows:
1.
Install a filter regulator and lubricator in-line before the clutch air pressure switch if they
are not already present.
2.
Connect shop air to the clutch air pressure switch input port.
3.
Run the cable through flexible, liquid-tight conduit, observing NEMA 12 requirements.
4.
Wire the normally open terminals of the switch between pin #8 and ground (e.g., pin #54)
on the WPC 2000 Main Processor board, referring to Figure 1 at the end of the manual.
5.
Set the clutch air pressure switch to 35 PSI, or the pressure recommended by the press
manufacturer.
Installing a Counterbalance Air Pressure Switch
Install and wire a counterbalance air pressure switch as follows if there is a counterbalance:
1.
Install a filter regulator and lubricator in-line before the counterbalance air pressure switch
if they are not already present.
2.
Connect shop air to the counterbalance air pressure switch input port.
3.
Run the cable through flexible, liquid-tight conduit, observing NEMA 12 requirements.
4.
Wire the normally open terminals of the switch to pin # 83 (User Input 4) and ground (e.g.,
pin # 54), referring to Figure 1 at the end of the manual.
USING RAMPAC (SMARTPAC 1 OR 2) TO CONTROL COUNTERBALANCE PRESSURE
If you use RamPAC to control the counterbalance pressure, install a pressure switch and
connect it to WPC 2000 as described in
Installing a Counterbalance Air Pressure Switch
,
page 2-15.
The clutch air pressure switch is held closed when pressure is applied above the setpoint limit.
If pin #83 has already been assigned to other user-selected auxiliary equipment, then wire
the counterbalance switch contacts across a terminal on the WPC 2000 Main Processor
board that generates an E-stop when the connection to ground is broken. See
Wiring
WPC 2000 User Inputs
, page 2-31 for more information.
