Section 5 – Troubleshooting
5.A Battery Voltage
The System effectiveness and accuracy is impacted when voltage of the power pack drops
below xxx VDC. Once the voltage drops below xxx. VDC, the battery indicator symbol will
accent on the display providing the user a warning / notification to source a replacement. This
will provide the user with a 30-45 day advance notice to obtain a replacement. See Section 2.A
for the battery symbol location.
5.B Simulate Signals
In the event a faulty sensor assembly or main PCB board assembly is failing, the user is able to
simulate signals to isolate the failed component. Be sure to clear out both Total Strokes and all
individual Pump Strokes prior to testing to verify results.
5.B.1 Microswitch
Using a flat head screwdriver to twist the rod to simulate a stroke, the installation
can be tested to see if the pump’s contact point is properly striking the Microswitch
sensor. If simulating the stroke displays properly on the Control Head, the pump’s
contact point is not making contact with the rod. Adjust rod/sensor location to allow the
rod to be properly struck during each pump stroke.
Opening the contact level box on the Microswitch Sensor is another way to test the
Microswitch Sensor. By tapping the White and Black wire leads, found inside the contact
level box, the user can simulate a stroke. If the Control Head registers a stroke, the
Microswitch Sensor will need to be replaced.
5.B.2 Proximity
Troubleshooting the Proximity Sensor will require the user to open up the local J-Box in
the pump room. At the local J-Box, the user can tap the Black and White wire leads to
simulate a stroke back to the Control Head. If a stroke is seen on the Control Head, the
Proximity Sensor will need to be replaced.
