03A162 Motion Detector Installation Overview
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.
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.
