Service Settings
Service Settings Menu
The Service settings menu has three distinct grouping of items within it.
The first group is the basic setups, non-password protected group that
consists of all of the settings, feature enables, setpoints etc, that are
benign; while they are unlikely to be changed often by a user or operator.
Changes in them do not seriously effect the standard protection or
reliability of the chiller.
If Refrigerant Monitor is installed in
Machine
Configuration, screens will
be displayed in
Refrigerant Report
and two (2) additional password
screens are required:
Refrigerant Monitor Settings Group
and
Refrigerant Calibration
Group.
The other two groupings are protected, each with a separate password.
These two groups are for changing parameters and settings regarding
field commissioning and fundamental protection and control of the chiller
subsystems
(Field Startup)
or for programming of the UCM as to how
the specific chiller was built in the factory
(Machine
Configuration).
Once properly set, the items in these protected menus should
never
be
changed again without specific knowledge of the effects of the changes.
CAUTION:
Settings in the Service Settings Group can only be set or changed
by ualified Trane Service Technicians. Improper settings in this
group may adversely affect the operation of the unit.
