Functional Specifications

Control Functions

UT ModeThe following types of basic control structure can be set asthe UT mode by the user.

Single-loop control (UT mode 1):The most simple and basic control function.

Cascade primary-loop control (UT mode 2):Output tracking function and cascade controllogic are provided. Suitable for cascadeprimary-loop control.

Cascade secondary-loop control (UT mode 3):Setpoint output and cascade control logic areprovided. Suitable for cascade secondary-loopcontrol.

Cascade control (UT mode 4):Dual control function for cascade control isavailable in a single instrument.

Loop control for back-up (UT mode 5):Output tracking function is provided to backup another control instrument. The local andremote control outputs are switched by acontact input.

Loop control with PV switching (UT mode 6):Two PV inputs are switched for controldepending on the status of contact input or PVinput.

Loop control with PV auto-selector (UT mode 7):Two PV inputs are automatically selected forcontrol with a high, low, average, or tempera-ture-difference value selector.

Loop control with PV-hold function (UT mode 8):This control holds a PV input and a controloutput if an external sensor is switched.

Control Computation FunctionsIn each UT mode, the following control computationfunctions can be selected:

Continuous PID control, Time-proportionalPID control, Relay ON/OFF control, Position-proportional PID control (for UT550-1 ,UT550-4 )and Heating/Cooling control (forUT550-2 ).

Target setpoint and PID parameters:Maximum eight sets of target setpoint and PIDparameters can be set. These eight sets can beset for both the main and slave loops incascade control.

Zone PID selection:Dividing PV input range into maximum 7zones by maximum 6 reference points, PIDparameter set switching in up to 7 PV inputzones.

Auto-tuning:Available as standard. Possible to activateauto-tuning for both main and slave loops forcascade control.

"SUPER" function:Overshoots generated by abrupt changes in thetarget setpoint or by disturbances can besuppressed.

"SUPER 2" function:This function stabilizes the state of controlthat is unstable due to hunting, etc. withoutrequiring any change in PID constants, whenthe load and/or gain varies greatly, or whenthere is a difference between the characteris-tics of temperature zones.

Preset output function:When the instrument is in STOP mode, PVinput is burnt-out, or an abnormality is foundin an input circuit, a preset value is output as acontrol output.

Sampling periodEach sampling period can be selected underthe following conditions:

50 ms: Available for model code UT550-00, whenUT mode is set to Single-loop control andthe following functions are not used:"SUPER" function, "SUPER 2" function,heating/cooling control, PV input computa-tion, setpoint rate-of-change limiter, MVoutput rate-of-change limiter, deviationalarm, sensor grounding alarm, faultdiagnosis alarm, and FAIL output.

100 ms: Available when UT mode is not cascadecontrol.

200 ms: Available when UT mode is cascade control.(Set value when shipped from the factory: 200 ms)500 ms: Always available.

Operation Mode Switching(Note: Communication enables all the following

mode switching to be executed.)AUTO/MANUAL switching:

Bumpless switching between automaticoperation mode and manual control mode isavailable by using the front keys or contactinput. The contact input has priority overfront key input or switching by communica-tion. The contact input is invalid for Cascadesecondary-loop control or Cascade control.

RUN/STOP switching:Switching by contact input (bumpless forswitching from STOP to RUN). The contactinput has priority over switching by communi-cation. In RUN mode, control computation isactivated. In STOP mode, control computa-tion ceases and a preset value is output as acontrol output while other functions operatenormally.

REMOTE/LOCAL switching:Switching between remote setpoint and localsetpoint by instrument operation or contactinput. The contact input has priority overinstrument operation or switching bycommunication. For remote to local switch-ing, either bumpless tracking (employing theremote setpoint on switching as the localsetpoint) or without tracking (directlyswitching the local setpoint) can be specified.

CASCADE/AUTO/MANUAL switching:Switching by instrument operation or contactinput. The contact input has priority overinstrument operation or switching bycommunication. Valid for Cascade second-ary-loop control or Cascade control.

Output tracking ON/OFF switching:Provided for Cascade primary-loop control orLoop control for backup. External trackingsignal and internal control output are switchedby the contact input. The contact input haspriority over the switching by communication.
