Explanation
This is simple example for temperature control. Model UT350 can read
:
the temperature from Type K sensor directly. Model UT350 also has very
powerful control functions, such as Auto-Tuning, SUPER function for
overshoot suppression, SUPER2 function for hunting suppression and
universal control output.
Customer can select a one control output from either Voltage Pulse, Relay
Contact or 4 - 20mA Current output.

Alarm set points are displayed on "Select Panel" for easy changing during
operation.
The ID control function will be stoped and a preset signal (0%) will be outputed
when the pump interlock signal will turn to on.
The current output signal is used to drive a control valve.

Explanation
:
This is a simple Heating / Cooling control example. Model UT350 has a Heating /
Cooling control function; however, two alarm outputs are enough to switch a ON/OFF
valve and a Heater.
1. If PV temperature is higher than (SP+2deg.C), a deviation Hi alarm turnes to ON.
Then, a cooling water valve is opened.
2. If PV temperature is lower than (SP-2deg.C), a deviation Low alarm turnes to ON.
Then, a heater switch is turned to on.

Explanation
Control the tank level by Proportional control with Manual Reset function.
:
Proportional control may occur small offset; however, the control response is
very fast.
UT350 has two types of power supply function to a two-wire transmitter.
All types of UT350 can supply 14.5VDC power to a transmitter.
Model UT350-3_ can supply 21.6VDC power to a transmitter.
A 14.5VDC will be enough for almost all analog type 2-wire transmitter.
A 21.6VDC will be used to drive microprocessor based 2-wire transmitter.

Explanation
Model UT350 has a RUN/STOP function.

STOP mode(Di2 is OFF):
PID control
PID computation is stopped.
Preset MV is outputed as MV.
UT350 can control the pump pressure without overshoot, because control
output starts from 0%.
UT350 can supply 14.5VDC power to a transmitter.
