Section 3.3.2 Counterbalance Air Valve System Mounting
The mounting location of the valve system is not critical. Consideration should be given,
however, to ease of maintenance, plumbing, and wiring when choosing the mounting location.
Also note that sometimes the check valve in the original system may be up at the surge tank
itself. The check valve in the original system must be removed for the automatic system to work
properly.
Section 3.3.3 Counterbalance System Wiring
Refer to Appendix B, Figure B.1, for typical wiring of the counterbalance valve and pressure
transducer. Note that the auto-select connection is used only for a type “C” valve. For type “A”
valves, the auto-select connection from pin 2 of the counterbalance board is not required.
Section 3.4 Cushion System Installation
The typical manually adjustable press cushion system looks something like Figure 3.12.
Figure 3-12 Typical Standard Cushion System
For automatic control, the pressure regulator and check valve are replaced with an air valve
system. Figure 3.13 shows a system using a Type “B” valve as described in section 3.2. Type
“A” and “C” valves may also be used. A pressure transducer is used to monitor the air pressure.
