). The voltage will continue to climb from that level. Do not allow V to exceed 27.0 volts on the 5220 - otherwise, the TEG may be damaged. Measured V measured across the precision resistor using a voltmeter while the electronics are in SETUP mode.
Inspect the TEG for damage that may have occurred during shipping. Please report NOTE: any damage to Gentherm GPT as soon as possible, as it may make the generator inoperable. Check with the factory before starting a damaged TEG. Assemble the TEG as shown in Figure 10, and mount it on a firm and stable base, sufficiently high above ground level to prevent the TEG from being inundated with water.

28142 Rev 15 PROCESS DESCRIPTION The minimum requirement for the 5220 is a limiter operating at a nominal voltage of 14 V. This limiter is a shunt-type voltage limiter that regulates the output voltage of the generator. The main components of the Limiter are shown in Figure 6, and explained below.
Power Resistor: When no load, or a very small load, is connected, the TEG has more power available than required by the load. This excess power is directed into a power resistor by the voltage limiter. Figure 7 – 220-Watt L/C Assembly Gentherm Global Power Technologies Page 18...
Page 25
28142 Rev 15 PROCESS DESCRIPTION A 220 W Limiter/Converter (L/C) is available for use with the model 5220 TEG. It is intended for use with model 5220 applications requiring nominal 24 VDC output. It consists of two separate circuits operating together. The first is a shunt-type voltage limiter that regulates the output of the generator.
This excess power is directed into a power resistor by the voltage limiter. An optional cathodic protection interface system is available for use with the model 5220 TEG. It provides for adjustment and monitoring of power to a Cathodic Protection (CP) load.

INSTALLATION This topic describes how to connect the fuel supply and gives considerations for providing fuel to the 5220 TEG. Connecting the Fuel Supply The TEG has a 1/4 in. female NPT fuel inlet - connection to the TEG’s manual shutoff valve.
(Figure 23). Do not use a different type of fuel than indicated. If you would like to convert your 5220 to run on a fuel other than the one indicated on the data plate, please contact GPT.
Clean Fuel: The fuel used to operate the 5220 TEG must be clean and dry. See Technical Specifications section for the full gas specification for fuel supplied to GPT’s TEGs. If dirty fuel is anticipated, then a customer-supplied in-line fuel filter is recommended.

STARTUP AND SHUTDOWN STARTUP AND SHUTDOWN This section describes how to start and shut down the model 5220 TEG. Before starting the TEG perform these steps: Move the jumper on TB-1 from the RUN position to the SETUP position, i.e. from between terminals 1 and 2 to between terminals 2 and 3 respectively.
Power from the 5220 TEG is produced by the difference in temperature between the burner and the cooling fins. This means the power output of the TEG is affected by the ambient temperature surrounding the generator.
Page 42
This method is suitable for ambient temperatures of up NOTE: to 65.5ºC (150ºF). If in doubt contact Gentherm Global Power Technologies’ (GPT) Customer Service Department for guidance. Example: Ambient temperature at site is 35ºC. Set-up power of 210 W and V 14.3 V, 22ºC is marked on the TEG Data Plate.

28142 Rev 15 ADJUSTMENT ADJUSTMENT This section describes how to adjust the Model 5220 Thermoelectric generator. Typical fuel pressure settings are 130 - 144 kPa (18.5 - 21 PSI) for natural gas NOTE: and 125 - 140 kPa (18 - 20 PSI) for propane.
28142 Rev 15 ADJUSTMENT GPT recommends the use of a combustion analyzer to tune the 5220 TEG. Tuning this way will result in a TEG that will run properly, cleanly, and reliably. See section 8.1.2.2 pf this manual for tuning instructions using a combustion analyzer.
Page 48
The TEG will require some time to stabilize after either air or fuel adjustments NOTE: are made. Wait 20-30 minutes between readings while adjusting fuel pressure. Gentherm Global Power Technologies Page 42...

There are two methods by which the air shutter can be adjusted: one using a combustion analyzer, and one using a meter. If the air shutter on the 5220 is closed too far, the flame will move up to the exhaust. A flame in the...
Air-Shutter Adjustment, Typical Air Shutter Adjustment Using a Combustion Analyzer GPT recommends the sue of a combustion analyzer to tune the 5220 TEG. The air shutter can be set more quickly and accurately using a combustion analyzer. A volt meter as described in the previous section is still necessary to verify power output.
Page 51
Avoid inhaling exhaust gases while working around or above the TEG. If the 5220 TEG is adjusted correctly, it will not emit excessive CO. When properly tuned, the 5220 should emit exhaust with a CO concentration of less than 800ppm (air-free).

Page 53
ADJUSTMENT Measuring CO Emissions Levels The model 5220 will not produce excessive amounts of CO if properly adjusted. Due to the open exhaust system of TEG, the CO measurement must be in the free air state. In a free air measurement, the allowable CO emission rate is 800 ppm. To be able to determine the...
Tighten the lock nut and replace the cover on the fuel regulator. An L/C is available for use with the model 5220 TEG, and it comes installed by default on all 24V 5220 TEGs. This text describes how to adjust the L/C parameters, if applicable.
Page 55
ADJUSTMENT Output Voltage Adjustment The L/C is factory set at 27.0 V (Model 5220-24V). If the output voltage requires fine tuning to better match your application, follow the below steps: Isolate the TEG from the load and batteries by opening the fuse or circuit breaker through which it is connected.
Page 56
Output Voltage Adjustment The Limiter is factory set at 14.1 V (Model 5220-12V). If the output voltage requires fine tuning to better match your application, follow the below steps: Disconnect the customer load from the TEG, terminals 4 (-) and 5 (+) of TB-1.
Page 57
Reset output voltage to the desired normal operating value. Consult the Data Plate label for the factory default voltage setpoint or adjust to your desired value. An optional CP interface system is available for use with the model 5220 TEG. This section describes how to adjust the CP interface system, if applicable.

Page 73
If the voltage is less than 6 V the battery assembly needs recharging or replacing. Check the Thermal Cutoff (TCO) The model 5220 TEG is equipped with a thermal cutoff (TCO) attached to the pressure switch. The TCO is a safety feature that prevents damage to the burner and fuel system. If cabinet temperatures exceed safe limits, a thermal fuse in the TCO assembly will open, closing the solenoid valve and shutting down the TEG.
1. Disconnect one of the wires from the pressure switch. Polarity does not matter in the pressure-sensing circuit, so whichever wire is more easily reached will suffice. a) For 5220 Remote-Start TEGs equipped with two pressure switches, use the switch connected with ORANGE wires.
Page 75
If battery voltage drops below 6 V during this time, replace the battery. Check the Solenoid Valve The 5220 is equipped with a solenoid valve to control fuel flow to the burner and act as a safety shutoff. A faulty solenoid valve may prevent a TEG from starting or shutting down correctly.
Page 76
Follow these steps to check the input voltage to the L/C or Limiter assembly: Disconnect the customer load from TB-1 terminals 6 (-) and 7 (+) for an L/C assembly (Model 5220-24V), or TB-1 terminals 4 (-) and 5 (+) for a Limiter assembly (Model 5220-12V).
