GENERAL DESCRIPTION

The 11028312 is a sealed xed position, Hall eect pulse pickup. It is intended to be mounted in the case of a 51 series cartridge motor in conjuction with a target ring mounted on the block of the motor. The 11028312 is designed to be powered directly from a battery on either 12 or 24 V systems. This device will be used for speed detection and has limited wire fault detection. Unit has gold plated contact terminals.

1. Insert PPU housing, align the hole in mounting ange with mounting hole in block housing.

2. Installation torque is 8 ± 1 N.m (5.9 ± 0.7 ft.lb) for bolt M6X12.

TROUBLESHOOTING

Tool required to perform the following steps: a volt-ohm-millimeter (VOM) set to read DC volts.

1. Ensure the pulse pickup is installed correctly. See Installation, on this page.

2. Check for pr

3. Check for speed output using a VOM across the black and white connections (pins 3 and 2). Turn pump or motor very slowly by hand or check output just as the prime mover is coming to a stop. Note a voltage pulse at meter. It will likely be dicult to read exactly, therefore simply note a pulse (approximately 60 pulses per revolution). If there is no indication of a pulse, replace the pulse pickup.
