1. INSTALL THE CONTROL BOX
Use the box itself as a template to determine the mounting
hole footprint. Install the box to a solid, stable surface
capable of supporting four times the weight of the box, or
about 20 pounds. Use all four mounting holes. Install the
control box to the wall using heavy-duty 1/4” or 6.3 mm
fasteners long enough to fasten the box securely. Do not
fully tighten mounting hardware at this time. Leave the
mounting hardware loose enough to work the conduit
into place. Hardware will be fully tightened following
installation of the conduit.
2. CONNECT THE SUPPLY AND LOAD
Feed the Input Supply (Input Power) and the Load (Heater
Cable) through the Conduit Entry Hole in the enclosure as
shown, then connect the leads, as shown in the Figure 3.
Line is black; neutral is white; ground is green.
Note:
Both the power and the load require a #10 AWG wire.
3. INSTALL THE TEMPERATURE SENSOR
The GPT 130 can use either a thermistor (provided), or
a 2–,3–, or 4–wire RTD sensor. The configuration of the
DIP switches must match the type of RTD sensor wiring
connection.
Thermistor (25076)
The GPT 130 comes with a thermistor temperature sensor
with a 20 ft. jacketed cable thathas an operating range
of −40 °F to 230 °F (−40 ˚C to 110 ˚C). See the diagram
below for proper wiring and DIP switch configuration
when using a thermistor sensor. Refer to Figure 4.
RTD
The unit can use an RTD sensor for applications requiring
a wider temperature range. The GPT 130 can operate with
2–, 3–, or 4–wire RTD sensors. Refer to Figure 4.
Note:
The sensor must be selected in the Sensor Type
parameter setting screen also.
Perform the following steps with the circuit breaker to the unit OFF. The TRACON GPT 130 is permanently
connected equipment and does not have an internal disconnect device. When power is applied, the system
will start.
