6 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. See
Figure 13
or Figure 14.
Connect a DC voltmeter to terminals 2 (+) and 4 (-) of TB-1. This will be measuring
V
set
.
Make sure that all the connections in the fuel system are tight and have been checked
for leaks.
Follow these steps to start the TEG using the Ignition Control System:
Supply fuel and open the manual shut-off valve. The spark ignitor should begin
clicking (sparking) and the sound of combustion will begin. In some cases, it may be
necessary to bleed air from the system. If combustion is not sustained after three
trials, see section 4.1.2 (Spark Ignition Control System) of this manual.
NOTE:
Once the TEG is started, closing the manual shut-off valve will shut it off.
WARNING!
When the TEG is operating, surface temperatures
near the thermopile, burner, exhaust
around the cooling fin duct may be more than 100ºC.
Avoid contact of skin and clothing with these areas
when operating in and around the TEG.
Thermoelectric generators are intended for continuous operation where reliable power is
required without interruption. To shut the TEG down for servicing or in an emergency, simply
cut off fuel to the TEG. This is easily accomplished by closing the manual ball valve provided
for installation with the unit.
