ABOUT THIS MANUAL
Global Power Technologies 62128 Rev12 Page 4
Trained Operators
Personnel performing installation, operation, and maintenance work should be properly
trained in such functions.
An operator should be familiar with technical terminology. Terms of particular significance,
defined for the model P-5100, are as follows:
Thermoelectric Generator (TEG): A device that produces electrical power through the
direct conversion of heat energy to electrical energy.
Power Unit (PU): The hermetically sealed portion of the TEG that contains the
thermoelectric materials and cooling fins.
Rated Power: Model P-5100 TEG produces 100 W when operating in an ambient
temperature of 20°C (68°F). With the fuel flow held constant TEGs operating in ambient
temperatures higher than 20°C (68°F) will see power output efficiency reduce, 0.4 W per °C
(0.2 W per °F) of temperature change up to a maximum ambient temperature of 55°C
(130°F). Conversely for temperatures lower than 20°C (68°F) power output efficiency will
increase by 0.4 W per °C (0.2 W per °F) of temperature change.
Set-up Power: Power from the power unit for a specific ambient temperature. It is derived
from voltage across a precision load, also known as VSET.
Set-up Voltage: VSET Voltage from the power unit for a specific ambient temperature, which
is proportional to set-up power. Fuel flow to the burner is adjusted so that proper voltage
exists, necessary temperature difference within the power unit maintained, to deliver
required power.
Open Circuit Voltage: Voltage at the terminals of the power unit when no current is flowing,
i.e., open circuit, which is related to the temperature across the thermoelectric materials
inside the power unit.
When a power unit lead is suddenly disconnected, breaking the circuit to the load, the voltage
measured across the power unit leaps up to a new value. This is known as the momentary
open circuit voltage (VOC).
Measured VSET: VSET measured across the precision load on the output of the electronics
without a customer load connected using a voltmeter.
Required VSET: VSET needed to achieve rated power for the present ambient temperature.
CP (Cathodic Protection): Thermoelectric generators are used in impressed current
systems for Cathodic corrosion protection of metallic structures such as pipelines.

ABOUT THIS MANUAL
Global Power Technologies 62128 Rev12 Page 5
CP Interface System: An assembly of electrical components system that acts as an
interface between the TEG and the CP load, which also provides for adjustment and
monitoring of power to the CP load.
Limiter Converter (L/C): A specific electronic device attached between the generator and
the load that converts one level of DC voltage to another and limits the power unit voltage.
Manual Shutoff Valve: A manually operated valve in the gas line for completely turning on
or shutting off the gas supply to the TEG.
Solenoid Valve (SV): A electrically actuated valve that controls the fuel gas supply to the
burner. This valve is operated by the Spark Ignition (SI) Module.
Spark Ignition (SI): The method and system used to ignite the TEG. Refer to section 4.1.2
for details.

QUICK START PROCEDURE
Global Power Technologies 62128 Rev12 Page 6
2QUICK START PROCEDURE
This section gives the key steps for setting-up the TEG. It is for the operator who is already
familiar with operating the TEG, having successfully completed Global Power Technologies
(GPT) TEG training course, and being a qualified service person with reasonable knowledge
and experience with industrial fuel and electrical equipment.
Follow these steps to install the TEG:
NOTE:
Inspect the TEG for damage that may have occurred during shipping. Please report
any damage as soon as possible as it may make the generator inoperable. Check
with the factory before starting a damaged TEG.
Follow these steps to start the TEG:
NOTE: Once the TEG is started re-closing the manual shutoff valve will shut it off.

QUICK START PROCEDURE
Global Power Technologies 62128 Rev12 Page 7
NOTE: Once the TEG is started pressing the Stop (S2) button or sending a SCADA Stop
signal to the TEG Controller (Remote Start) board will stop it.
WARNING!
When the TEG is operating, surface temperatures near the
thermopile, burner, exhaust stack and around the cooling
fin duct may be more than 100°C. Avoid contact of skin
and clothing with these areas when operating in and
around the TEG.
Follow these steps to adjust the TEG:
CAUTION!
Do not allow measured VSET to exceed required VSET,
determined in the POWER OUTPUT EVALUATION
section, otherwise overheating may cause irreparable
damage to the power unit.
NOTE: Details for adjusting the L/C and optional CP interface systems, if applicable,
are in the ADJUSTMENT section.
Your TEG is now operating successfully, making available continuous electrical power to the
load. It is recommended that a record be kept of the TEG’s performance and maintenance
history. Each time adjustments are made, or servicing is carried out the details should be
recorded. A blank TEG Performance Log is provided at the end of this manual.
NOTE: Servicing requirements are given in the MAINTENANCE section.

TECHNICAL SPECIFICATIONS
Global Power Technologies 62128 Rev12 Page 8
3TECHNICAL SPECIFICATIONS
This section gives the technical specifications for the Model P-5100 Thermoelectric generator.
The Model P-5100 Thermoelectric Generator (TEG) converts heat directly into electricity with
no moving parts. It is a reliable, low maintenance source of DC electrical power for any
application where regular utilities are unavailable or unreliable.
The Model P-5100 Thermoelectric Generator provides 127 Watts of electrical power from the
power unit at the beginning of life and at an ambient temperature of 20°C. This power is
generated at a nominal 6 Volts, which can then be converted to other voltages using the
voltage converter. The TEG system outputs at least 100 Watts of net electrical power from
its 12 Volt or 24 Volt converter.
If the generator is to be operated at load conditions that force the output voltage of the
power unit to vary significantly from 5.5 Volts, then less than the rated power will be available
to the load. Figure 6 identifies the electrical parameters of the P-5100’s power unit as a
function of the load resistance.
Mounting Stand: The P-5100 can be conveniently mounted on any platform with four holes
spaced as shown in Figure 11. It is important to mount the TEG at a height sufficient to
prevent direct flooding or heavy snowfall from interfering with the flow of cooling air. A
mounting stand is available from GPT.
Cathodic Protection Interface (CP): The Cathodic Protection Interface option provides a
termination point of cathode and anode cables up to 9 mm (00 AWG) in size, a meter to
monitor the voltage and current of the CP circuit and an adjustable resistor to control the
output power.
Remote Start System (TEG Controller Board): The Remote Start option provides a
method of starting and stopping the TEG either locally or remotely, using on-board buttons,
SCADA signal interface or system measurements.
VSR Terminal Block: The optional VSR terminal block is an additional wiring harness that
provides the VSR and current measurement connection on a terminal block inside the TEG
Cabinet as opposed to directly connecting to the electronic circuit board.
48 VDC Converter:The 48 VDC Converter Option allows your model P-5100 generator to
supply a nominal 48V output voltage from the standard 24V TEG output. The Converter
Assembly is installed on the left side of the TEG and connects to the main terminal block TB1
inside the TEG cabinet.
NOTE:
Specifications shown are for standard configurations.
Global Power
Technologies’ Engineering Department is available
to design installations
meeting different specifications including custom voltages, fuel supply
systems and nonstandard operating temperatures.
