Motor Control Board Settings - Trane BCHE Installation, Operation And Maintenance Manual

ECM Overview and Setup
may be on the back-side of the low voltage access lid,
depending on the unit configuration.
The serial number of each unit and the custom
configuration settings specific to that unit will be printed on
the label for convenient matching of labels/settings to
specific units. Programming a unit with the settings from
another unit will result in abnormal operation. The label
contains four important sections:
• How to enter the configuration menu
• The description and meaning of the error codes
• The description and meaning of the status display
• The parameter names and values specific to that unit

WARNING
Safety Alert!
Failure to follow instructions below could result in
death or serious injury.
In addition to the following tasks, you MUST:
• Follow all instructions in the unit's Installation,
Operation, and Maintenance manual, including
warnings, cautions, and notices.
• Perform all required tasks in any applicable
Service Alerts and Service Bulletins.
• Review and understand all information provided
in Submittals and Design Specifications.
CAUTION
Burn Hazard!
Failure to follow this instruction could result in the
unit overheating and becoming hot to the touch,
which could result in minor or moderate injury, and/or
equipment damage.
On electric heat units, certain parameter values are
locked out to prevent overheating of the unit. These
functions will appear to be saved; however, they will
not be accepted if the Electric Heat Protection setting
is "On". Do not change the Electric Heat Protection
setting to "Off" and make changes to the protected
settings unless you are programming an
unconfigured service replacement board to match the
unit settings on a ECM configuration label.
NOTICE
Motor Damage!
Failure to follow instructions below could result in
motor damage.
Do not change PWM output voltage settings.
Note: The motor control board functions and unit specific
settings are summarized on the motor control board
configuration label affixed to the back side of the
control panel low voltage lid, on every unit.
The following table lists the parameter names and typical
settings of the motor control board, for reference only.
Do not change the electric heat protection settings if your
unit has electric heat.
If the format setting for rpm values are not correct (i.e., not
four-digit: XXXX), please check the operation mode of the
motor control board m m o o d d 1 1 and m m o o d d 2 2 and motor signal
output format S S I I G G 1 1 and S S I I G G 2 2 .
Note: The following notes are provided for reference only,
and the motor control board label must be used as
the ultimate guide for setting up an motor control
board on specific units.
