â– Temperature control with thermo
label
On the damper, a thermo label is attached as a
guide.
When the thermo label reaches the specified
temperature, the white heat-sensitive area turns
black.
Control and Record the temperature regularly, and
check any abnormal temperature changes.
• Once the heat-sensitive area of the
thermo label turns its color, it will
never return to the original color again.
• A thermo label is attached as a guide. It
is recommended to measure the
temperature while operating the
engine with a noncontact thermometer
(thermo gun) and to control and record
it accordingly.
1 Make sure with a noncontact
thermometer (thermo gun, and
others) that the surface of the
engine is cooled down so that you
can touch.
2 Stick a thermo label (1) onto the
outer face of the damper.
• Avoid the stamped marking.

3 Operate the engine at the rated load
for about an hour.
4 Operate the stop switch "Starting
and Stopping Devices Installed
during Manufacturing the Generator"
(→ Page 87) of the generator to turn
off the engine.
5 Check the heat-sensitive area of the
thermo label and record the highest
temperature.
ï‚®If a temperature rise is observed, locate the
defect in the engine or other causes. In
addition, replace the thermo label with a
new one and check the change of
temperature again.
• If the detected temperature comes
close to the limit temperature of the
damper, or if there is any abnormal
change in temperature, contact your
SME dealer
"CONTACT LIST" (→ Page
8).
• For the temperature limit of the
damper, refer to
"Table8-4 Limit
Temperature of Damper" (→ Page
