03A162 Motion Detector Installation Overview


03A162 Motion Detector

Speed Requirements – A speed of 6 RPM or higher is required for operation of the motion detector. If the press camshaft, drive-chain or drive-belt drive speed is slower than this, the speed can be increased by means of a gearbox, sprocket or sheave with the proper ratio.

Chain Drives – If the press has a chain-driven cam box, connect the motion detector to this linkage. Fit the motion detector with a sprocket that has same or fewer number teeth than the drive sprocket. The number of teeth can be the same if the speed of the drive sprocket is 6 RPM or greater; otherwise, the number of teeth must be fewer.

Belt Drives – Belt-driven systems are acceptable, provided there isn’t excessive slippage. One-to-one coupling accuracy is not necessary, but the system must provide reliable rotation in excess of 6 RPM while the press is in motion.

Safety Note

Note – When a chain or belt-driven system is used, the mounting bracket for the motion detector must be tight, rigid and unaffected by vibration from die contact or machine stop. The chain or belt and sprocket or pulley must also be tight. Any looseness in the drive path will result in erratic motion signals and cause timing errors, nuisance alarms, or both.

Direct Drives – If the main shaft or the cam box is accessible, it may be possible to attach the motion detector to it by direct shaft, flexible coupling or a gear.

Electrical Connection – The motion detector comes with a 10′ cable which is connected to the terminals in the end of the motion detector and terminals 13 & 14 on the control unit. If a longer cable is required, any two-conductor cable may be used; although, it is preferred that the cable be twisted-pair or shielded.

Important – the cable from the motion detector should be routed away from any other wires, to minimize the possibility of noise problems.
