Unit Control
Panel (UCP)
Diagnostic Screen
The
diagnostic screen
is
accessible by touching the
Alarms
enunciator.
When an alarm is present, the
alarm enunciator is present next
to the Stop key. A flashing
“alarm” indicates a machine
shutdown and a non flashing
“alarm” indicates an
informational message.
Machine shutdowns can be of
two types:
Latching (MMR) require
corrective action and manual
reset.
Non-Latching (MAR) will restart
automatically when condition
corrects itself.
Up to ten active diagnostics can
be displayed if required.
The reason for all diagnostics
must be determined and
corrected. Do not reset and
restart the chiller as this can
cause a repeat failure. Contact
local Trane Service for assistance
as necessary.
After corrective action, the chiller
can be reset or restarted. In the
case of a diagnostic type, the
chiller will have to be manually
reset through the Diagnostics
alarm menu.
When reset they become historic
and viewable via the TechView
™
.
Performing a
Reset All Active
Diagnostics
will reset all active
diagnostics regardless of type,
machine or refrigerant circuit.
A
Manual Override
indicator
(shares space with the Alarms
key) alerts the operator to the
presence of a manual override.
An Alarm will take precedence
over the manual override, until
the reset of active alarms. The
manual override indicator would
reappear if such an override
exists.
Temperature settings
can be
expressed in F or C, depending
on Display Units settings.
Dashes (“- - - -”) appearing in a
temperature or pressure report,
indicates that the value is invalid
or not applicable.
The
languages
for DynaView
™
will reside in the main processor.
The main processor will hold
three languages, English, and
two alternate languages. The
TechView
™
will load the main
processor with user selected
languages from a list of available
translations. Whenever possible,
complete words will be used on
the persistent keys as described.
