Control and Monitoring are Different Control Monitoring • Control – Varying the heating cable output to achieve the desired temperature • Monitoring – Providing feedback on the status of 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 Digi. Trace 910 6

Self-Regulating Control is Simple Distribution Panel Power Connection Heating cable End Seal 7

Ambient Sensing Control Main Contactor Distribution Panel Ambient sensing thermostat 8

Ambient Sensing Thermostats Fixed 40°F setpoint AMC-1 A AMC-F 5 9

Line Sensing Control Distribution Panel Line sensing thermostat or Digitrace 910 10

Line Sensing Thermostats Fixed 40°F setpoint AMC-1 B AMC-F 5 11

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 12

Monitoring Using GFPD Distribution Panel Power Connection Heating cable End Seal GFPD 13

Digi. Trace 910 • • • 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 15

Temperature Monitoring w/910 Distribution Panel W/ Standard Circuit Breaker Digi. Trace 910 RTD 16
