2-12 Installation
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 # 31), referring to Figure 2 at the end of the manual.
5.
Set the counterbalance air pressure switch 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 Operator Station(s)
The Operator Station should be installed in a location from which the operator can
conveniently run the press. On most gap-frame (OBI or OBG) presses, this will be on the
front of the bolster. For straight-side presses, the Operator Station may be installed on the
press or on a pedestal.
The Operator Station should not be permanently mounted until you have calculated the
correct safety distance (see Calculating the Safety Distance, page 3-19) and performed the
applicable verification (see page 2-58) and checkout (see page 3-35) tests. When you have
finished wiring, you can place the Operator Station temporarily on the floor or on a cart.
If you are not installing a light curtain, and if you are planning to use the Operator Station as a
two-hand safety device, the Operator Station must be mounted at the correct safety distance
from the nearest pinch point on the press. This distance must be calculated based on the
Stopping Time of your press. See Calculating the Safety Distance, page 3-19 for details.
Mounting the Operator Station at the correct safety distance prevents an operator from leaving
the station and reaching the pinch point before the press stops.
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 2-28 for more information.
USING RAMPAC (SMARTPAC 1 OR 2) TO CONTROL COUNTERBALANCE PRESSURE
If you use RamPAC to control the counterbalance pressure, set the WPC 2000
counterbalance pressure switch to the pressure required to balance the empty ram.
