Control and Monitoring are Different
Control
•Control
– Varying the heating cable output to
achieve the desired temperature
•Monitoring
– Providing feedback on the status of
Monitoring
the heat-traced system
5
Options for XL-Trace
•Self-Regulating
•Ambient sensing control
– Ambient sensing thermostats
•Line sensing control
– Line sensing thermostats
•Monitoring & Control with DigiTrace 910

Ground-Fault Monitoring
•
•
Advantages
– Monitors integrity of heating cable and power
distribution wiring
– Readily available equipment
– Low installed cost
Disadvantages
– Monitors cable integrity, not performance
– Required bell alarm contract on GFPD

•
•
910 Single point electronic
controller (920 Multi-point)
Approved GFPD replaces t-stat and
ground fault breaker
Compatible with BMS,
Networkable
Provides temperature, current and
ground fault monitoring
Order RTD separately
14
Temperature Monitoring
•
•
Advantages
– Measures performance (will it freeze?)
– Provides extensive alarm capability
- Low and high temperature
- High Low Amps
- High Ground fault & Ground Fault trip
– Can be networked to each other & a PC
Disadvantages
– Expensive to install on each circuit
