PRIOR TO INSTALLATION
1. Read these installation instructions and manual prior
to beginning installation.
2. Install this device only if you are a qualied electrician
trained to perform such work.
3. Before beginning installation, lay out the system
components, the heat trace cable and the
temperature probe in their approximate locations to
visualize the system and evaluate exact component
and junction box placement, as well as required
cable and conduit lengths.
INSTALLATION
The GPT 230- Automatic Heat–Trace Control should be
installed by a qualied, licensed electrician. Installation
must conform to all applicable local and national electrical
codes and laws. The unit’s NEMA 4X IP66 enclosure allows
for indoor or outdoor applications.
The GPT 230- controller has an ambient operating
temperature range of −40 °F to 131 °F (−40 °C to 55 °C).
To avoid potential internal condensation mount the unit
out of direct sunlight.
Install the GPT on a xed, at, vertical surface using
the unit’s mounting anges. The mounting anges
accommodate 1/4” or 6.3 mm fasteners.
The GPT 230-’s nonmetallic enclosure has one 1.046” hole
for conduit entry; this can hold both power and load wiring.
Use only Listed Type 4X IP66 liquid–tight conduit hubs
or cable glands. Connect the hub to the conduit system
before connecting the hub to the enclosure.
The unit comes with two installed liquid–tight cable
glands. One of these ttings is for the temperature sensor
cable, and the other is for the alarm relay cable.
The cable glands can accommodate cable diameters
0.08” to 0.24” (2 mm to 6 mm). The temperature sensor
may be located up to 2,000’ (610m) from the GPT.
There is a removable electrical insulation divider that
must be in place when there is power applied to the unit.
All leads should be terminated; no unsecured leads
should be left inside the wiring compartment.

Perform the following steps with the circuit breaker to the unit OFF. The TRACON GPT 230- is permanently
connected equipment and does not have an internal disconnect device. When power is applied, the system
will start.
NOTE:
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 230 can use either a thermistor (provided), or
a 3–wire RTD sensor.
Thermistor (25076)
The GPT 230 comes with a thermistor temperature sensor
with a 20 ft. jacketed cable that has an operating range
of −40 °F to 230 °F (−40 ˚C to 110 ˚C). See the diagram
below for proper wiring and DIP switch conguration
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 230 can operate
with 3–wire RTD sensors. Refer to Figure 4.
Note: The sensor must be selected in the Sensor Type
parameter setting screen also.
4. INSTALL THE EXTERNAL ALARM
An alarm or power–off condition can be communicated
by either opening or closing a relay contact. It is important
to make the proper alarm relay connections to achieve
the desired result. The middle terminal labeled COM
(Common) is used in both wiring congurations. Connect
one alarm relay lead to the COM terminal. If the system
needs a contact to close to signal an alarm or power–off
condition, connect the other alarm relay lead to the NC
(Normally Closed) terminal.
If the system needs a contact to open to signal an alarm
or power–off condition, then connect the other alarm
relay lead to the NO (Normally Open) terminal.
If the unit has power, and there are no alarm conditions
then the NO and COM terminals will be connected. If
the unit loses power or an alarm condition occurs then
the NC and COM terminals will be connected. Refer to
Figure 5.
5. PANEL LOCKOUT
To prevent unauthorized changes of control settings, the
second DIP switch can be set to the on position to Lock
the settings. With Lock enabled, the control panel will
allow viewing but not changing any of the settings; only
the °C or °F option can be selected. Refer to Figure 6.
Note: The GPT reads the Lock DIP switch position when

the Settings screen is entered. If the switch is changed,
you need to re-enter the Settings screen.
6. INSTALL THE CONDUIT AND FULLY
TIGHTEN HARDWARE
Install the conduit runs to the control box. Use only Listed
Type 4X IP66 liquid–tight conduit hubs. With cabling
routed through conduit and conduit is secure, fully tighten
the control box mounting hardware and re-assemble
control box panels and cover in their original location.
Note: At this point the circuit breaker to the unit can be
turned on providing power to the unit.
7. SETUP AND SETTINGS EDITING

instructions for Setup and Settings Editing.

cannot be used for Pilot Duty applications.
Resistive Load Usage Only
This product is not for use with Inductive loads.
Inductive loads may create nuisance tripping of
the Ground–Fault Equipment Protection circuit.
Abnormal Odor or Smoke
In the event of smoke or a burning or abnormal
odor, immediately interrupt power to the unit by
turning off the circuit breaker protecting the unit.
Electrical Shock / Fire Hazard
Any installation involving electric heater wiring
must be grounded to earth to protect against
shock and re hazard. Suitable ground fault
detection and interrupting systems must be in
use at all times to reduce shock and re hazard
and to protect equipment.
Electric wiring to heating elements must
be installed in accordance with National
Electrical Code (NEC)/Canadian Electrical
Code requirements, as well as all other local
and applicable electrical codes and any
thirdparty standards. This product is intended
for commercial and industrial applications.
Follow the installation instructions contained in
this manual and those provided by the heater
manufacturer.
Size the circuit breaker appropriately for the
expected load and inrush current. The maximum
rated current for the GPT 230 is 30 amps with
resistive load.
Heater loads and their controls should not share
a circuit branch with other types of equipment.
A shared circuit may result in electromagnetic
interference that can affect system operation.
Make certain that the heater shield is properly
grounded. Failure to do so may result in damage
to the equipment or re.
Following installation and prior to beginning system
operation, refer to and perform the Post-Installation Test
described in this manual.
