Safety Note

 

This overview is meant to demonstrate how easy it is to install and setup the DM3000 - it is not intended to act as a substitute for the detailed instructions contained in the DM3000 User's Manual.

Please read the manual carefully before attempting an actual installation.
 
 

 

Mount the unit to the press. Use the Shock mount kit provided with the unit and install it exactly as shown in Figure 1.

Connect terminals 1, 2 & 3 to Ground, L1 and Neutral, respectively, of a 120 VAC line. (Figure 2)

Connect terminals 4 & 5 across the press Brake/Clutch Valve. (Figure 2)

Connect terminals 6 & 7 (DM3000 Stop Output) in series with the press control E-Stop Circuit.(Figure 2)

Connect terminals 10, 11 & 12 to interface for Loss of Motion. This is only for some older Allen-Bradley press controls. (Figure 2)

Connect the Motion Detector directly to the press camshaft with a flex-coupling (not included) or in the cam/crankshaft drive chain loop with a sprocket (not included).

Apply power. Run the DM3000 in the Autolearn Mode - the unit will automatically calculate alarm settings for your press.

You are finished. The unit will now measure Stop Times and monitor the condition of the brake.

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.
