The Microswitch assemblies are pre-connected to the “Y” cable assembly and may
require the cable to be disconnected from the contact lever box ½” NPT gland so the
cable assembly can be routed into the cable trays.
3.B.2 Proximity Cable
The Cable Assembly is routed through a local J-Box in the Pump Room. There will be
one cable from the Control Head to the J-Box, and from the J-Box to the Sensor, there will
be a cable for each pump being monitored, these cables are referred to as the pump legs.
3.C Sensor Assembly
3.C.1 Microswitch
The switch assembly has the contact lever box, wand, and C clamp. The C Clamp
mounts to the adapter plate for easy installation.
3.C.2 Proximity
In order to install the proximity sensor onto the pump shaft properly, the user will need to
know the specific pump model and manufacturer being monitored so that HDI can review
its list of existing fabricated brackets. See current available bracket list provided by HDI
in Section 7.E of this manual.
Note: The proximity sensors require careful measurements to ensure proper installation.
The Sensors can double stroke on the out and return stroke. The all
thread pick up sensor stem is assembled with a 2’ pigtail and a connector. The mating
cable assembly has an open lead for local junction box termination. Please review the
appendix for an example step-by-step guideline on how to properly install the proximity
sensors based on the Wirth 2200 Series pumps.
The all thread stem and magnet should be adjusted so the components are no more than
1.25” apart. Typical installation would leave a ½” – ¾” gap when properly installed.
Prior to closing up the inspection plate, review the details to ensure no potential damage
will be caused by having the all thread stem and magnet positioned too close together.
