Table of Contents◗OVERLOAD PROTECTION DEVICES“Air Champ” ®OVERLOAD PROTECTION SYSTEMOverload Protection System (OPS)is a combination of a flangemounted,air engaged clutch andan electronic control thatelectronically detects clutch slip intorque overload conditions. Uponrecognition of the overload, thesystem disengages the clutch, andcan operate an external signallingdevice (i.e. warning light/alarm).OPS includes two proximitysensors: one mounted on theclutch input, and one mounted onthe clutch output. The controlcompares the signals from theindividual sensors and determinesif the clutch is slipping.◗ The clutch is re-engaged at anyspeed, and at any position of theclutch interface◗ The clutch torque is remotelyadjusted with a simple air regulator◗ The motor disconnects from theload when an overload occurs, sothe motor runs cooler and moreefficiently, without current surgesand blown fuses◗ The OPS also prevents the motorrotor inertia from contributing todamage caused by torque overloads◗ The FMCEclutch is self-containedand protected from dirt and debris◗ The controller is available in aNEMA Type 12 enclosure, or as astand-alone board for panel mounting◗ OPS operates on standard AC orDC voltages and frequencies◗ Quick connect/disconnect wireconnection coupling◗ Soft-start capabilities providesmore sensitive overload protectionthan ball-detent mechanisms122◗ OVERLOAD PROTECTION SYSTEM (OPS)Model: OPS - Chassis Version OPS - Enclosed VersionProduct Number: 964403 964404Input Power 12 VDC @ 800 mA 12VDC @ 800 mAOptions: 115 VAC @ 110 mA 115 VAC @ 110 mA230 VAC @ 57 mA 230 VAC @ 57 mAInputs: Inductive proximity sensors: Inductive proximity sensors:npn, open collector, current npn, open collector, currentsinking or NAMURsinking or NAMUROutputs: Relay: 28 VDC, 115/230 VAC Relay: 28 VDC, 115/230 VAC@ 2 Amps.@ 2 Amps.K1: 12 VDC @ .6 Amps K1: 12 VDC @ .6 Ampspower available, used topower available, used tooperate clutch solenoid.operate clutch solenoid.K2: available for auxiliary K2: available for auxiliaryuse.
