1128600 SmartPAC 2 with WPC 2000 Integration User Manual
2-12 Installation
The power supply on the mounting plate is pre-wired to the power terminal, TB105, on the
Main Processor board and to the input power terminal block on the plate. To connect AC
wiring to the input power terminal block, follow the instructions in Connecting AC Wiring,
page 2-9.
Installing a Dual Safety Valve
If you have ordered a Ross or Herion DSV with your WPC 2000, refer to the appropriate
wiring diagram at the end of this manual and to the documentation that came with your valve
to install the DSV. Note the following requirements:
• Ross DM2
To wire the Ross DM2 DSV, refer to figures 18 and 22 at the back of the manual.
The Reset circuit requires that a diode be installed across the coil in the solenoid to provide
noise suppression (see Figure 22). This wiring has already been done for you in the
Hirschmann connector for the 24 Vdc Reset solenoid, which is provided along with two
Hirschmann connectors for the 120 Vac valve solenoids in the Ross DM2 kit.
The Reset solenoid connector comes in two styles. One has a black shell with an electrical
circuit including a diode symbol ( ) printed on it, the other a transparent shell with a red
LED indicator visible inside. You install this connector on the Reset solenoid at one end of
the DSV. The Reset solenoid connector is the only connector at this end of the DSV. The
other two connectors are installed on the two valve solenoids at the other end of the DSV,
USER-SUPPLIED DUAL SAFETY VALVE NOT SUITABLE FOR SAFETY USE
Ensure that your dual safety valve meets the applicable safety standards. Contact the valve
manufacturer for information.
Failure to comply with these instructions will result in death or serious injury.
INSTALL DSV CLOSE TO CLUTCH/BRAKE ASSEMBLY TO REDUCE STOPPING TIME
Install the dual safety valve as close as possible to the clutch/brake assembly. Any excess piping
between the valve and the clutch/brake assembly increases the Stopping Time of the press.
Failure to comply with these instructions will result in death or serious injury.
DSV MUFFLER CLOGGING OR LOOSENING
• Clean the DSV muffler periodically. A clogged muffler can degrade Stopping Time.
• Tighten the muffler securely to the valve body. Periodically check to make sure the muffler is
securely installed. Vibration may cause it to loosen and fall. To tighten the muffler, secure the
valve body, hold the muffler with both hands and turn clockwise as tightly as possible without
stripping the threads.
Failure to comply with these instructions could result in death or serious injury.
