Step 13: Determine if monitoring equipment is required:
Monitoring increases system reliability by detecting faults before they become a major problem. Consider the following points when planning
heating circuit monitoring:
While you may select only one method of control for each trace heating circuit, you can make use of various monitoring options. The use of
monitoring increases overall system reliability because failures in the heating and power distribution systems get reported to operations per-
sonnel.
BARTEC recommends to always use, at a minimum, ground-fault monitoring. For the small additional cost, you get a monitoring system that
reliably reports physical damage to the trace heating system, which is a common failure mode.
For sensitive applications, add end of line monitoring with either a high profile end seal or an end of line light. The end of line light gives the
most direct visual feedback on system performance.

Maintenance access through a high profile end seal
The high profile end seal is used to quickly locate the end of the heating circuit for troubleshooting in the field. It provides a convenient way to
locate the end of the circuit and for testing of voltage presence at the end of the circuit.
Continuity monitoring using an end of line light
Continuity monitoring is used to verify that the trace heater circuit has voltage present at the termination end. This is often assured by an end of line
light installed as part of the end seal. In addition to the visual feedback at the end of the trace heater circuit it provides easy maintenance accessibility.
