CAUTION!
Do not allow measured V
set
to exceed that required
V
set
, for present ambient temperature, otherwise
overheating may cause irreparable damage to the
power unit.

V
set
will rise quickly at first then begin to level out. It will take at least one hour for
the V
set
to level out. When no longer V
set
changes (±0.2 V in ten minutes) compare
this value with required V
set
. Measured V
set
should be within 0.2 V of that required.
NOTE:
Typically, if the measured V
set
is greater than required V
set
then the fuel
pressure needs to be reduced.

Examining V
set
after Running for Some Time
Once the TEG has been running for some time, typically more than an hour, with load
attached the power unit will be warm.
Follow these steps to check V
set
after running for some time:
1.
Disconnect the customer load from the TEG, terminals 7 (+) and 8 (-) of TB-1 and
allow to stabilize for 15 minutes.
2.
Consult the data plate inside TEG door for the reference V
set
voltage and determine
the required V
set
for the present ambient temperature. See Working-out Required V
set
or Setup Power topic above, or Alternative Method of Working-out Required V
set
or
