Application of the Clear Language Display to the
UCP2 Centravac
CVHE-CLD-1A (February 2000)
Updated information and incorporated FastPak™
items.
About This Manual
This manual describes the application of the Clear
Language Display (CLD) to the UCP2 Centravac. It
describes its use as a machine-mounted human
interface.
A description of the UCP2 reports and message
displays are provided along with additional “Help
Notes” to clarify the display messages. In addition, a
Diagnostics section is also included.
LCD Display
The display on the Clear Language Display is a 2-
line by 40-character liquid crystal display (LCD).
Upper and lower case alphabetic characters can be
displayed,along with numeric and special
characters.
LCD Backlight
The LCD display has an LED backlight so it can be
read in low light conditions.
Keypad
A sealed dirt-proof keypad is used on the unit mount
Clear Language Display. Metal dome switch
actuators respond when any key is pressed. See
Figure 1 .
Important! FACTORY DEFAULT SETTINGS: Menu
items that are programmable using the keypad may
have a selectable choice that is listed as Factory
Default. This Factory Default setting is the software
default that is initially factory-programmed for a new
module assembly and may NOT be the correct
setting for a specific operating chiller. Always review
all settings when any module is replaced to verify
that the settings agree with the desired settings that
were selected at initial startup or programmed at the
factory.
LED Alarm
In addition to the alpha-numeric LCD display, there's
a single discrete LED on the human interface. The
red LED flashes on-off whenever a latching
diagnostic is present and a manual reset is required
to restore full unit operation. The LED is also used to
indicate that a function or control has been set to
manual from within the Service Test Menu. If a
control has been set to manual, the LED is on and
non-flashing. A diagnostic supersedes a manual
operation. As a result, the unit could have a manual
mode set and be in a latching diagnostic. In this case
the LED would flash on-off. The LED is off otherwise.
Figure 1
Keypad Matrix
Local Clear Language
The Local CLD “Clear Language Display” resides at
the Chiller providing display of chiller data and
access to operator/service controls, setpoints, and
chiller set-up information. All information is stored in
non-volatile memory in the Chiller module. The Local
CLD and the Chiller module work together to display
and store information requiring non-volatility.

Control System
Unit Control Panel
Safety and operating controls are housed in the
UCP2 unit control panel, the starter panel, and the
purge control panel.
The UCP2 control is a modular design partitioned by
major function or group of functions. All modules (see
Figure 2 ) communicate with each other through the
Interprocessor Communication Circuit (IPC).
Major components within each control group are
shown in the figure.
Unit-mounted temperature sensors, pressure
transducers, and functional switches provide analog
and binary inputs to the various modules.
The microcomputer-based modules are illustrated in
the figure. All wiring to the modules are to pluggable
terminal blocks.

Custom Report
Custom Report Group
Reports are added to the custom report group by
pressing the <+> key when the desired report is
being displayed from its normal report location.
Reports are removed from the custom report group
by pressing the <-> key when the desired custom
report is being displayed. The Custom report group
can contain a maximum of 20 reports. When adding
a report to the Custom Report, if the <+> key is
pressed when the Custom Report already contains
20 reports, a message, “Custom Report Is Full,
Report Not Added,” indicating that the Custom
Report is full,will be displayed for 2 seconds. If an
attempt is made to add a report to the Custom Report
that is already in the Custom Report, a message,
“Report Already In Custom Menu”, will be displayed
for 2 seconds.
The Custom Report sequence is as follows:

Chiller Operating Mode
The chiller operating modes display comes up first in
the standard report:
Line 1 (and 2 if needed) indicates a current condition
of the unit as shown in the following table (Table 1) .
In some cases, an associated timer or system
