WARNING: Do not use in swimming pool or spa areas; pump has not been investigated for this application.
WARNING: In the event the retaining screws have been pulled out of the housing, DO NOT replace them.
Use of any other screw may short out the stator windings, creating a risk of electrical shock.
CAUTION: When installing electrical connections, do not apply mechanical loads to the capacitor box;
otherwise, retaining screws may be pulled out of the housing, making circulator unusable.
Troubleshooting
As in any troubleshooting procedure, it is important to isolate a problem as much as possible before proceeding. The error messages
greatly simplify troubleshooting of the 00-VS. When the 00-VS flashes an error message, identify the fault and follow standard testing
procedures to confirm the problem. If you suspect a wiring fault, return to the wiring section on this brochure and carefully check all
external wiring and wiring connections.
For your safety and protection of permanent damage to the microprocessor, the 00-VS includes a 2.5 A 250 V (ac) field replacable fuse.
Testing The Sensors
A good quality test meter capable of measuring up to 5,000 kΩ (1 kΩ = 1000 Ω) is required to measure the sensor resistance. In addi-
tion to this, the actual temperature must be measured with a good quality digital thermometer.
First measure the temperature using the thermometer and then measure the resistance of the sensor at the 00-VS. The wires from the
sensor must not be connected to the PC Board while this test is performed. The wiring terminals are easily removed by pulling them
from the PC Board. Using the chart below, estimate the temperature measured by the sensor. The sensor and thermometer readings
should be close. If the test meter reads a very high resistance, there may be a broken wire, a poor wiring connection or a defective
sensor. If the resistance is very low, the wiring may be shorted, there may be moisture in the sensor or the sensor may be defective.
To test for a defective sensor, measure the resistance directly at the sensor location.
