Miscellaneous (continued)
Moisture Protection - The NEMA4X
and IP66 rated front face permits use in
applications where it may be subjected
to moisture, dust, or hose-down
conditions.
Setpoint Ramp/Soak Programming
(Optional) - Enables you to program and
store six Ramp and six Soak segments
for setpoint programming. Run or Hold of
program is keyboard or remote digital
switch selectable.
Setpoint Rate - Lets you define a ramp
rate to be applied to any local setpoint
change. A separate upscale or
downscale rate is configurable. A single
setpoint ramp is also available as an
alternative.
Limit Control - Provides a latching
relay, which is activated whenever the
PV goes above or below a preset
setpoint value. An indicator will light
when the output is activated and the
lower display will show a message.
Reset is through a key on the front of the
controller or an external switch. A FM
approved model is available.
CE Mark - Conformity with 73/23/EEC,
Low Voltage Directive and 89/336/EEC,
the EMC Directive as a standard feature.
Approval Body Options - CSA
certification is available as an option. UL
listing is standard.
Two Sets of Tuning Constants - Two
sets of PID parameters can be
configured for each loop and
automatically or keyboard selected.
Data Security - Five levels of keyboard
security protect tuning, configuration,
and calibration data, accessed by a
configurable 4-digit code. Nonvolatile
EEPROM memory assures data integrity
during loss of power.
Diagnostic/Failsafe Outputs -
Continuous diagnostic routines detect
failure modes, trigger a failsafe output
value and identify the failure to minimize
troubleshooting time.
High Noise Immunity - The controller is
designed to provide reliable, error-free
performance in industrial environments
that often affect highly noise-sensitive
digital equipment.
Quality/Support - The UDC2500 is
covered by a 18-month warranty and
backed up by a toll-free phone number
for technical assistance (US Only).
Accutune III™ - This standard feature
provides a truly plug and play tuning
algorithm, which will, at the touch of a
button or through a digital input,
accurately identify and tune any process
including those with deadtime and
integrating processes. This speeds up
and simplifies start-up plus allows
retuning at any setpoint. The algorithm
used is an improved version of the
Accutune III
TM
algorithm. Two
possibilities are now offered when tuning
your process: Fast Tune and Slow Tune.
Fast Tune will tune the process in such
a way that the temp is reached faster, a
slight overshoot will be allowed.
Slowtune will minimize overshoot, but it
will take more time for the process
temperature to reach the target setpoint.
Heat/Cool (Duplex Tune) will
automatically tune both the heating and
cooling sides of the process.
Fuzzy Logic - This standard feature
uses fuzzy logic to suppress process
variable overshoot due to SP changes or
externally induced process disturbances.
It operates independently from
AccutuneIII™ tuning. It does not change
the PID constants, but temporarily
modifies the internal controller response
to suppress overshoot. This allows more
aggressive tuning to co-exist with
smooth PV response. It can be enabled
or disabled depending on the application
or the control criteria.
Operator Interface
Indicators—Provide alarm, control
mode, and temperature unit indication.
There is also indication of when
Remote Setpoint is active, the status
of the control relays, and whether a
setpoint program is in Run or Hold
mode.
Displays— During normal operation,
the upper display is dedicated to the
process variable (4-digits) and special
annunciator features. During
configuration, the upper display
provides guidance for the operator
through prompts (6-characters).
During normal operation for the dual
display model, the lower display shows
key-selected operating parameters such
as Output, Setpoints, Inputs, Deviation,
active Tuning Parameter Set, Timer
Status, or minutes remaining in a
setpoint ramp (4 digits). During
configuration, the lower display provides
guidance for the operator through
prompts (6-characters).
You decide how the controller is to
interact with the process by selecting,
through simple keystrokes, the
functions you want.
Multi-language prompts guide the
operator step-by-step through the
configuration process assuring quick
and accurate entry of all configurable
parameters. Five languages are
available via configuration: English,
French, German, Spanish and Italian.
Decimal Point Location—
Configurable for none, one, or two
places.
Dedicated Keys—Provide direct
access setpoint modes and setpoint
program status to simplify and speed
operation.
