Introduction
Three Local and one Remote Setpoints - Can be configured to provide three Local and
one Remote Setpoints, which are selectable either via the keyboard or by Digital Input.
Universal Switching Power - Operates on any line voltage from 90 to 264 Vac 50/60 Hz
without jumpers. 24 Vac/dc instrument power is available as an option.
Timer - This standard feature provides a configurable time period of 0 to 99 hours, 59
minutes or units of minutes and seconds. It can be started via the keyboard, alarm 2, or by
a digital input. The timer output is Alarm 1, which energizes at the end of the Timer
Period. Alarm 1 can be automatically reset. The Timer Period can be changed between
each batch. Status is shown on the lower display.
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.
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.
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 II
TM
algorithm found on earlier controllers. 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.
