Display Heater
The HMI Control Panel is equipped with a display heater. This
heater is needed to make the display visible in very cold
ambient temperatures.
The HMI has its own internal temperature sensor for the
display heater. The heater is energized when the unit is turned
on and the ambient temperature is below 29.4 F (-2 C). The
heater turns off when the temperature sensed by the internal
sensor rises above 37.4 F (+3 C). The heater draws from 1.4 to
1.7 amps when energized.
The colder the ambient temperature the longer it will take for
the heater to make the display visible on a cold startup. It may
take 10-15 seconds for the display to appear with extremely
cold temperatures.
If a Language is Enabled
If more than one language has been enabled from the Guarded
Access Language Menu, a prompt will appear to allow the

specifically enabled from the Guarded Access Menu are
available. If a different language is desired, press the NO Key

IMPORTANT: The engine start is not delayed by the
language prompt shown below. The prompt will appear for 10
seconds and then the engine will start. After the engine is
