TRACE
MATE II-CTR
1.1
Product Overview
Introduction
The TraceMate II-CTR solid state heat tracing control is
an electronic thermostat designed to maintain two
seperated heaters at their respective desired setpoint
temperatures. It is suitable for use with mineral-insulated,
self-regulating or constant-wattage cable in applications
such as freeze protection, process control and instrument
tracing. The TraceMate II-CTR is intended for indoor or
outdoor installation in ordinary or class 1, division 2
hazardous locations.
TraceMate II-CTR offers many advantages over other
heat tracing control schemes, which generally use some
combination of mechanical thermostats, custom-built
panels or programmable controls to provide control,
monitoring and alarm functions. Wiring costs are mini-
mized by mounting the control in close proximity to the
heat tracing cable and pipe. A NEMA 4 enclosure and
wide temperature range electronic components are used to
make mounting possible in most locations. Temperature
sensing of each heater is achieved by mounting a 100 ohm
platinum (DIN 43760) RTD sensor on the pipe. Heater
current is controlled by a solid state switch rated 30A.
The temperature setpoint and other setpoints are digital
for fast non-ambiguous setting over a wide range. Instant
system information such as pipe temperatures, heater
currents, ground fault currents, and heater on/off & alarm
status can be seen on the LCD display mounted on the
door of the enclosure. Maximum system reliability is
obtained from a comprehensive alarm package which
includes LCD display messages and LED indicators for
quick fault identification and a ground fault trip to
minimize fire hazards.
By combining the control, system monitoring and testing
requirements of a heat trace control system into a general
purpose control, the TraceMate II-CTR makes it possible
to significantly upgrade systems at low installed cost. In
addition, it is very flexible in its application to adapt to
specific user requirements.
