    • Adjustable alarm thresholds for excess ground fault OVERVIEW current, load current, and temperature The TRACON GPT 230 Dual Channel Heat–Trace Control • Alarms indicated with panel display and relay contact is a dual–point microprocessor–based heat–trace control for remote signaling thermostat.
  • Page 3 The GPT 230 is permanently connected equipment and FIGURE 1. The GPT 130 wiring layout does not have an internal disconnect device. The installer must provide an accessible disconnect device, with short circuit and overcurrent protection (these are not supplied by Environmental Technology Inc). When power is applied, the system will start.

  • Page 4: Operation

    Contactor Ratings POWER SOURCE AND CONTACTOR CONNECTIONS The heater contactor provides two (2) Form A (DPST) Supply Voltage contacts rated for heater loads up to 30 A ac and 277 V ac. The GPT 230 operates from 100 – 277 V ac at 50/60 These two contacts are used to control both legs of the Hz.
  • Page 5 TEMPERATURE SENSOR The unit can use RTD sensors for applications requiring Each channel of the GPT 230 can use either a thermistor a wider temperature range. The GPT 230 can operate (provided), or a 2–,3–, or 4–wire RTD sensor. When using with 2–, 3–, or 4–wire RTD sensors.
  • Page 6 The heater will de-energize when the temperature meets the designated High Temperature. The GPT 230 features ETI’s patented self–testing GFEP, which switches the system off when it detects excessiveground current leakage. The GFEP eliminates the extra expenses associated with having to provide an external GFEP.
