for Clutch and Counterbalance Air Pressure
DANGER
!
USER-SUPPLIED DUAL VALVE MAY NOT BE SUITABLE FOR SAFETY USE
Ensure that your dual valve meets the applicable safety standards. Contact the valve
manufacturer for information about your valve.
Failure to comply with these instructions will result in death or serious injury.
DANGER
!
LONGER 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.
DANGER
!
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 will result in death or serious injury.

Dual Safety Valve

Your WPC may have come with a DSV manufactured by either Herion or Ross. These
valves are installed differently. Install and wire them according to the appropriate wiring
diagram at the end of this manual and to the documentation that came with your valve. Note
the following requirements:
• Herion – Make sure that you wire the Herion DSV monitor between terminal #20
and +24 VDC out. See wiring diagram Figure 4 at the end of this manual.
• Ross – A Ross DSV requires a separate user-supplied N/O reset switch. See wiring
diagram Figure 6 at the end of this manual.
