Product data

Features/Benefits (cont)
Automatic two chiller lead/lag
capability provides integral standby
controls.
A 16 line by 40 character LCD
display offers ‘‘all in one glance’’
access to key chiller operating
information.
Local Interface Device (LID) pro-
vides unparalled ease of user inter-
face. The LCD display features 4
menu specific softkeys and a simple,
intuitive design.
Modular pull-out/plug-in design
requires minimal wiring and simplifies
installation.
Low voltage design is safe and
reliable.
Battery backup provides protec-
tion during power failures and elimi-
nates time consuming control
reconfiguration.
The extensive service menu can be
password protected to prevent unau-
thorized access. Diagnostic capabilities
assist technicians in troubleshooting
and recommend proper corrective
action for pre-set alarms, resulting in
greater machine uptime.
An automatic capacity override
feature prevents nuisance shutdowns
by unloading the compressor when-
ever key safety limits are approached.
Encapsulated circuit boards,
designed and built by Carrier, offer
superior reliability compared to open
board designs. Stringent quality
standards are enforced and ensured
through in-house construction.
Optional control modules offer
unique control expandability that
includes chilled water reset, demand
limit from remote sources, and much,
much more.
Extensive factory testing
Components are tested individu-
ally and after assembly to en-
sure quality and outstanding
performance.
ASME inspections of all pressure
vessels occur at major points of
assembly. ASME rated materials and
processes result in the ‘‘U’’ stamp,
a sign of pressure vessel integrity.
Compressors are 100% run tested
before mounting as an additional
step in the quality process to ensure
proper functioning.
Hydrostatic vacuum and pressure
testing of assembled chillers en-
sures leak integrity.
The controls and optional unit-
mounted starter are tested after
mounting to verify proper electrical
functioning.
An optional certified or witnessed
ARI (Air Conditioning and Re-
frigeration Institute) 550 perfor-
mance test is available.
Storage tank and pumpout
system
Carrier’s policy is to protect the
environment by ensuring the
containment of refrigerant during both
operation and service. To help meet
this requirement, the 23XL chiller can
be teamed with an optional partner:
The 19XB Positive Pressure Stor-
age System. See the 19XB Product
Data manual for further details.
