Heat Trace Panels have ground fault/overload alarm option.
Press Release Summary:
Sentinel monitoring alarm option on weatherTRACE freeze protection heat trace panels continually monitors supply voltage to individual heat trace circuits. Loss of voltage or ground fault condition triggers alarm condition, while annunciator panel identifies faulted zone. Common Alarm is activated with re-ring feature, which allows panels to communicate additional alarm conditions in system by momentarily clearing and resetting alarm output contact.
Original Press Release:
Chromalox Offers Ground Fault/Overload Alarm Option for Heat Trace Controls
PITTSBURGH-February 24, 2004 - Chromalox®, the world's largest manufacturer of industrial heat and control products, announces a new option to its weatherTRACE line of freeze protection heat trace panels. The new Sentinel monitoring alarm option continually monitors the supply voltage to each individual heat trace circuit without the need for additional staff. Loss of voltage or a ground fault condition triggers an automatic alarm condition, alerting plant personnel of critical process problems and reducing downtime. An annunciator panel then identifies the faulted zone and a common Alarm is activated with the re-ring feature. This new capability reduces troubleshooting time and provides better indication of potential problems on the line.
The re-ring feature allows the weatherTRACE to communicate additional alarm conditions in the system by momentarily clearing and resetting the alarm output contact. The user's monitoring device, such as a PLC or DCS, can interpret this condition as an additional alarm. The re-ring feature reduces monitoring costs and allows quicker identification and resolution of problems in the heat trace system.
About weatherTRACE
The Chromalox FPAS, FPLS, FPASM, and FPLSM series freeze protection heat trace panels offer power-distribution, ground-fault protection, individual circuit alarming, and line and ambient sensing control. The panels are standard housed NEMA 4 enclosures for indoor/outdoor applications. NEMA 4X 304 stainless steel enclosures may be selected as an option for more harsh environments. The standard models are available in 12, 18, 20, 30, and 42 position panelboards with 100 and 225 amp bus ratings in single and three- phase configurations. Branch circuit breakers are available in 20, 25, 30, and 40 amp single-pole and two-pole configurations with 30 mA ground-fault equipment protection. The FPAS - Freeze Protection Ambient Sensing Series controls groups of heat trace circuits with an external ambient sensing control or thermostats.
Chromalox recommended On/Off controllers include: RTAS, RTAS-EP, B100, E100 or a panel door mounted 1601E microprocessor controller. The FPAS may be operated in two modes automatically with the external controller, or in manual override via the Hand/Off/Auto selector switch.
The FPLS - Freeze Protection Line Sensing Monitor Series controls heat trace lines with individual Chromalox RTBC, RTBC-EP, E-100 or E121 pipe line sensing controls. Multiple sensors should be used to control the individual circuits or may be gauged based on the application and amperage.
The FPASM - Freeze Protection Ambient Sensing Monitor Series controls groups of heat trace circuits with an external controller/ thermostat. The FPASM series require external ambient sensing control or thermostats. Chromalox recommended On/Off controllers include: RTAS, RTAS-EP, B100, E100 or a panel door mounted 1601E microprocessor controller. The FPASM may be operated in two modes; automatically with the external controller or in manual override via the Hand/Off/Auto selector switch. The FPASM WeatherTrace is also available with the Sentinel feature, as described above.
The FPLSM - Freeze Protection Line Sensing Monitor Series controls heat trace lines with individual Chromalox RTBC, RTBC-EP, E100 or E121 pipe line sensing controls. Multiple sensors should be used to control the individual circuits or may be gauged based on the application and amperage. The FPLSM, like the FPASM, is also available with the Sentinel option.
