No Configuration
If at power up the unit has not been programmed with the
necessary configuration data for normal unit operation,
the following display will appear on the Human Interface
LCD screen. When this screen is being displayed, the only
functional key is the CONFIGURATION key.
Note:
This screen will only appear when the RTM has
been field replaced. Refer to the Configuration
Menu.
Factory Presets
The UCM controlled unit has many operating functions
which are preset at the factory, but may be modified to
meet the unique requirements of each job. The following
list identifies each of the unit’s adjustable functions and the
value assigned to it. If these factory presets match the
application’s requirements, simply press the AUTO key at
the Human Interface module to begin unit operation (after
completing the Pre-Start and Start-Up procedures in the
Installation, Operation, and Maintenance manual). If the
application requires different settings, turn to the listed
page beside the function, press the designated function
menu key, then press and hold the NEXT or PREVIOUS key
until its screen appears on the LCD. Once the proper
screen appears, simply follow the programming
instructions given below the applicable screen in this
manual.
Note:
Record any changes made to the factory-preset
values in the corresponding space provided.
