SERVICE SETTINGS
Machine Configuration Group
Machine Configuration Group Setpoints
Machine configuration settings define selection of
variations in the unit. The settings define indirect or direct
fired, size, and other optional features.
The Machine Configuration group is Password Protected.
The password is
+ - + - + - Enter
If the machine configuration password is entered, the
display goes to the menu defined below. If a key is not
pressed every 10 minutes after entering the menu, the
display returns to the Chiller Operating Mode display of the
Chiller Report. The password must be entered again to
return to this menu.
Editing menus in the Machine Configuration group is not
allowed unless the machine is off (for example Local Stop,
Remote Stop). This feature is shown below on an example
setpoint screen where the second line of the setpoint
display indicates whether or not a setpoint change is
allowed. If a (+)(-) key is selected when not in a stop mode,
the display will indicate that changes to the setpoint are not
allowed with a brief message. Example: (Where "setpoint
description" can be any setting item in the menu).
Possible values of status are: Press (+)(-) to Change Setting,
Machine Must Be Stopped To Change Configuration.

1. Machine Configuration Group Heading
This header is not suppressed if the headers in the Service
Settings menu are not revealed.
2. Unit Frequency
Possible values of Frequency are: 60 Hz; module default, 50
Hz
3. Unit Types
Possible values for type: Direct-Fired module Default, 1
Stage (Hot Water), 1 Stage (Steam), 2 Stage (Hot Water), 2
Stage (Steam)
4. Nominal Unit Tons
Possible values of [tons] are "100" through "2000" in 10
ton increments. The module default is 500 tons.
5. Rated Load Amps
The range of values is 0-2500 in 1 amp increments. The
module default is 50 Amps.
6. Current Gain Setpoint
This selection is used by UCP2 to determine when the
current transformers are outputting a secondary current
that reflects the full load RLA. The actual output is
compared to the expected value based on this setting to
determine the % of total current. This is then multiplied by
the RLA value (item 5 above) to display the total current.
The range of values is decimal 00 through 31. Module
default is 00.
Motor current overload is handled with individual motor
overloads or the AFD.
Note: The current overload setting terminology was used
on older UCP2 models. See current transformers in the
panel section for setup information.
7-8-9 Indirect fired only
