The instrument can program up to 4 ramp/soak steps.
Up to 16 different modes of ramp/soak operations are possible.
For obtaining the optimum PID parameters, the autotuning procedure is
used. The autotuning
procedure can be manually set on or off.
Also, fuzzy control procedure is a standard procedure for
suppressing the overshoot and improves the response to disturbance without
changing the PID parameters. Due
to these functions, optimum control parameters suitable for each
application is obtained.
This controller provides a wide selection of alarm types to configure up
to two alarm contacts. Alarm
types with Hold are configured in the controller.
Upon power on, the alarm action is suppressed by the Hold action
until the input value has entered the non-alarm range.
In a single controller, both heating and cooling output are obtained
because two control outputs are used. The use of heating/cooling output control contributes to
energy savings in applications where process generated heat exists.
The controller can be set to the overlap or deadband mode.
