INDIVIDUAL COMPONENTS The components for these full-revolution control systems will vary depending on the actuating means and the modes of operation that are chosen. To simplify this, component packages are available. Please see pages 15-16 for part numbers and descriptions of the component packages. The control system can include the following components. Inlet 1.3 Outlet 1.2 Exhaust 2.4 1⁄4” MONITORED DUAL-SOLENOID AIR VALVE Part No. RCD-140* This three-way, ¼” monitored dual-solenoid air valve is ideal for operating air cylinders on full-revolution presses. This dual valve is pneumatically checked. To assist in installation, this valve has a common electrical connector for both solenoids with a 12-foot cord. 1⁄4” FILTER-REGULATOR-LUBRICATOR ASSEMBLY (FRL) Part No. RCL-043* This assembly is needed to meet the OSHA and ANSI requirements. This FRL assembly filters, regulates, and lubricates the air going through it. This filtered and lubricated air then goes to the solenoid air valve assembly and air cylinder. The regulator should be adjusted so just enough air pressure reaches the air cylinder to operate the clutch. This assembly includes a gauge, coupling, and steel mounting bracket. 1⁄4” Monitored Dual-Solenoid Air Valve AIR PRESSURE SWITCH Part No. CTD-062* This air pressure switch is needed to meet the OSHA and ANSI requirements. The air pressure switch monitors low pressure to either the air cylinder air supply or ram counterbalance systems. The pressure switch must be set so if the air pressure operating the components is not adequate, or if the air pressure suddenly drops, the press becomes inoperable. Filter-Regulator-Lubricator Assembly CAM AND STRAP ASSEMBLY Part No. CML-002* A cast-aluminum cam and adjustable stainless-steel strap are furnished so the cam can easily be mounted on the crankshaft extension. The strap is adjustable up to 6” diameter and is locked in place by tightening the screw. Note: Drilling or tapping the end of the crankshaft is not required. All that is required to install it is to slip the cam and strap assembly on the crankshaft, line it up with the top-of-stroke limit switch assembly, and tighten. See next page. *Included in a component package on pages 15-16. Air Pressure Switch Crankshaft Extension Cam and Strap Assembly 14 | CONTROL SYSTEMS
FULL-REVOLUTION-CLUTCH PRESS CONTROL SYSTEMS INDIVIDUAL COMPONENTS (CONTINUED) TOP-OF-STROKE LIMIT SWITCH ASSEMBLY Part No. CMK-103* This top-of-stroke limit switch assembly with a 25’ cord is actuated by the cam mounted on the crankshaft and is specifically selected for this application. The top-of-stroke limit switch provides dual force-guided contacts to provide the signals when the machine is in the single stroke mode of operation. If the machine does not stop at top dead center, or if the switch assembly malfunctions, becomes improperly adjusted, or the mounting becomes jarred loose, the control will not allow a successive stroke. A mounting bracket for the limit switch assembly is not furnished. To purchase the EX-AL mounting bracket material shown in the photo, please contact Rockford Systems at 1-800-922-7533. To meet OSHA and ANSI safety requirements, the two run/jog buttons must be protected against accidental operation (with ring guards) and separated to require the use of both hands to operate them. They also must be mounted at the proper safety distance, if they will be used as a safeguard. The electrical contact arrangement of the following buttons is 1 NO and 1 NC. Part No. CTL-502* This palm button assembly consists of two black run/inch buttons (with ring guards), a red emergency-stop button, and a yellow top-stop button. Mounting boxes are furnished with each button. The red and yellow palm buttons each have 1 NO and 1 NC arrangement. The red button is on a yellow-covered mounting box and is equipped with a mechanical latch to meet NFPA 79. Part No. CTL-507* This palm button assembly consists of two black run/inch buttons (with ring guards), and a red emergency-stop button (for press applications without the continuous mode of operation). Mounting boxes are furnished with each button. The red palm button is on a yellow-covered mounting box and has 1 NO and 1 NC arrangement plus a mechanical latch to meet NFPA 79. See pages 98-99 for other palm button assembly options. FOOT SWITCH Part No. CTD-011* To meet OSHA and ANSI safety requirements, a foot switch must be protected from unintentional operation. The foot switch pedal (on the inside) is protected on the top and both sides by the cast cover and the front is protected by the hinged flap. This flap must be raised by the operator’s toe before allowing the foot to enter the switch. When the hinged flap is in the down position, it is also mechanically interlocked with the operating pedal. The contact arrangement is 1 NO and 1 NC. Top-of-Stroke Limit Switch Mounted Above Cam and Strap Assembly on the Crankshaft Foot Switch Part No. CTL-502 Part No. CTL-507 *Included in a component package on page 15-16. CONTROL SYSTEMS | 15
