Test the Exhaust Manifold
Temperature Sensor
Note: Genie specifications require that this
procedure be performed every 1000 hours of
operation or yearly.
Yearly calibration of the exhaust manifold
temperature sensor is essential to safe machine
operation. Continued use of an improperly
calibrated temperature sensor could result in
failure to sense an accurate exhaust manifold
temperature. This could create a hazardous
situation.
Component damage hazard. This
procedure requires specific repair
skills and testing equipment.
Dealer service is strongly
recommended.

5 Remove the jumper wire from the back of the
temperature display.
Result: The display will show
programming changes are being saved into
memory.
Note: Do not turn the machine off before removing
the jumper from the back of the display. If the
machine is turned off before the jumper wire is
removed, all data may not save completely or
correctly. This could result in a fault display of
the next time the machine is turned on.
6 Use a precision DC voltage power supply with
an output range of -10 mV DC to 60 mV DC
and an accuracy of 0.03% or better. Connect
the negative lead to the
positive lead to the
temperature display.
7 Set the power supply to mV DC and turn the
power supply on.
8 Compare the voltage on the temperature
display to that of the power supply over a range
of -10 mV DC to 60 mV DC.
Result: If the voltage differences between the
temperature display and the power supply are
within 0.02 mV DC at all points over the range
of -10 mV DC to 60 mV DC, the display does
not need to be calibrated.
Result: If the voltage differences between the
temperature display and the power supply are
more than 0.02 mV DC at one or more points
over the range of -10 mV DC to 60 mV DC, the
display will need to be calibrated. See How to
Calibrate the Temperature Sensor Voltage
