The following steps require a 1/2 inch open end wrench with standard 22° oset and a Volt Ohm
Meter (VOM):
1. Installation
First ensure that KPP is installed correctly. There are distinct directional and installation
procedures, (reference Procedures for Flat End and Conical End Models, page 14 to 15).
2. Speed Signal
Check for speed output using a VOM. Place VOM across the ground and speed pins or
terminals, (reference Dimensions, page 7) and set VOM to the DC Volt scale and low range. To
check for an output, 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,
simply note a pulse (approximately. 60 pulses per rev.). If there is no indication of a pulse,
replace KPP.
3. Directional Signal
Check for a direction signal change using a VOM. Use the same VOM setup as in the above
speed signal check. Turn the motor slowly and note a polarity change (±) on the VOM display as
you change the motor direction.
