Troubleshooting steps

Light is dim 1. Check that light voltage rating matches supply voltage for heat-tracing circuit. Supply voltage lower or higher than light rating
or off. will cause malfunctions.
2. Check that heat-tracing circuit is energized. Although the circuit breaker is on, control devices such as thermostats may switch
heating cable off.
3. Following electrical safety procedures, disconnect supply voltage, unscrew light from end seal base and check that crimp
connections to heating cable bus wires are tight and not crossed or shorted. Loose connections or shorts will cause malfunctions.
4. With circuit off, attach volt meter leads to crimps. Energize circuit and measure voltage at light. Use the following table to
determine whether the voltage measured is within the acceptable range.

• If voltage at light is in acceptable range and connections are good, the light may be defective or damaged. Replace light.
• If there is no voltage at the light, there may be breaks in the heating cable between the power connection and the end seal.
Check for splice or tee connections that may be left open.
• If voltage at light is above specified limits, the light may be off. Voltages above specified range can damage light. Replace light
with correct version for line supply voltage or adjust supply voltage accordingly.
• If voltage at light is present but below specified limits, the light may be dim or off. The following table lists typical causes for
low voltages and possible solutions.
Cause
Supply voltage at start of circuit is low (light is designed
to work with supply voltages within 10% of nominal).
Heating cable length is too long (light is designed to
work with published maximum circuit lengths).
Heating cable is started under very cold conditions
(heating-cable voltage drop is very high for first minutes
of very cold start-up).
Heating cable controller is reducing voltage (light may
not work with controllers that phase fire to reduce line
voltage).
Problem Troubleshooting steps
Cap cannot be 1. Check that heating cable is installed and stripped correctly. The top of the insulated parallel crimps should be 2 3/8 in (60 mm),
tightened or less, above the top of the plastic strain relief in the stand.
completely.
2. Check that core sealer is positioned properly. The end of the core sealer must be flush against the plastic strain relief in
the stand.
3. Check that the threads on the light and stand are clean. The connection wires between the heating cable and the light should
not be caught in stand threads.

Solution
Increase power wire gauge size to reduce voltage drop
between panel and heating cable power connection.
Split heating cable into multiple circuits. Shorten length of
heating cable.
Wait for heating cable to warm up. Voltage at light will
increase.
Turn off phase firing function in heating cable controller.
