Pump Stroke Counter

Special attention should be observed when replacing a proximity sensor assembly to
ensure the sensor is properly adjusted to pick up the pulses as the pump strokes.
Section 4 – Maintenance
The HDI 2100 Pump Stroke Counter System will require the following periodical maintenance.
4.A Power Pack
The System is powered by an internal 3.6VDC power pack that is warranted for 12 months from
the date of shipment. On average, the power pack will last 18 months based on 24 / 7 operation;
however, if the user is able to turn off the unit when not in use, the battery life can be greatly
extended.
4.B Processor Boards
The LCD has two (2) internal processor boards: the HDI 012 and the HDI 02 debounce
processor board, both of which can be replaced in the field if either component has failed. In the
event there is an issue with a specific pump’s SPM rate, the user may be able to simulate signals
to help isolate which PCB has failed. Section 5 provides some basic troubleshooting tips.
Additionally, please contact HDI Technical Support for additional suggestions.
4.C Sensors
Depending on the pump configuration, either sensor type can be replaced as a full assembly kit
or partial components based on what components have been damaged or have been found
faulty. See related Section 7 BOM illustrations.
4.D Increasing Existing PSC Pump Capacity
To increase the number of pumps on an existing PSC, a pump sensor kit will need to be
purchased. The kit includes a spare sensor (Proximity or Microswitch) with specified cable. The
bulkhead connector on the back of the Control Head and the mating connector for the cable
assembly must be replaced; the replacement connectors are shipped with the pump sensor kit.
In addition, if the pump legs are joined together with a 3M-splice kit, the user will have to cut the
legs, remove the splice and replace it with a J-Box. The J-Box is also included in the pump
sensor kit.
