1. After performing controller specific commissioning,
observe the display on the ECM engine board with the
power on, to the unit. The ECM engine display should
display a looping status indicator as follows:

Notes:

• The indicator is unit-specific and may indicate
"Off" at this point; refer to thermistor function for more
information.
• A representative fan speed of "1050" rpm are shown in
the following example. Each unit is factory-configured
differently and will have different settings for different
fan speeds.
2. While the unit remains on, exercise the fan controls on
the unit, either directly or indirectly through request for
unit heat/cool. Observe the fan spinning, and then
observe the fan display on the ECM engine board. It
should display a looping status indicator as follows:

This function protects settings on the
board that affect the safety of the electric
heat system.

This function shortens the ramps for faster
unit commissioning and auto-resets to off
after approximately 15 minutes of power-
on operation.

Notes:
These notes are provided for reference
only, and the ECM engine label must be
used as the ultimate guide for setting up an
engine board on specific units.
Do NOT change this setting. This setting locks
out the following parameters from being
changed, for safe operation of the unit.

To aid in commissioning of the unit, for
approximately 10–15 minutes, the ramps will be
shortened to quickly observe proper unit
behavior and response to speeds.

speeds):

Note: The indicator is unit-specific and may
indicate "Off" at this point; refer to thermistor
function for more information.
3. OPTIONAL:
While the fan is running, if practical, change the fan
speeds and observe the display temporarily indicate:

Exercise all fan speeds to ensure positive unit
response and to validate any field wiring.
Congratulations! Your new Trane BLDC Engine/Motor
system is performing properly.
