SECTION 3—INSTALLATION OF COMPONENTS
Air Pressure Switch
(If furnished—See enclosed Manual KSL-165)
The clutch/brake air supply must be monitored by an air pressure switch on all part revolution power presses. If an
air counterbalance is used, it must also be monitored by a separate air pressure switch. Please check the machine
owner’s manual for the minimum suggested air pressure for these switches.
Mount this switch at any convenient location on the machine. Electrical and pneumatic connections to the switch are
required; therefore, its location is determined by the installer. Flexible hose is often used for air connections. Since
only air pressure is being monitored, tubing size can be small and length is not critical. The switch is set to open the
electrical circuit any time pressure falls below the preset level. It is normally set in the 30 to 40 PSI range to prevent
unnecessary opening due to a surge in line pressure during the clutch engaging period. The minimum setting for
the air counterbalance pressure may be in the 20 to 30 PSI range (see machine manufacturer’s recommendations.
Check Valves for Counterbalance Systems
(If furnished)
If the machine is equipped with an air counterbalance system, a check valve is required by OSHA to prevent a sudden loss of air pressure to the
system. This valve is available in various sizes. The size is determined by the pipe size of the incoming air supply to the air tank, which supplies the
air to the counterbalance system. The valve should be installed in the air line just before the tank. When complete energy isolation is required, for
maintenance on the machine or counterbalance system, be sure that air is released from the counterbalance, cylinders, tank, etc.
Do not install this valve between the cylinders and tank.
