1) Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert
an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC220500U from TDK) on the secondary side.
As a countermeasures against noise, do not place the primary and secondary power cables close to each other.
2) For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires
that have low conductor resistance and cause no significant differences in resistance between the three wires.
The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.
3) Control output relays may be replaced. However, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load.
4) The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or
relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as
a spark-removal surge suppression circuit, into the line in parallel with the load.
5) When there is possibility of being struck by external lightening surge, use the arrester to protect the instrument.

Thank you for purchasing the UP350 program controller.
The controller is shipped from the factory with 4 hardcopy user’s manuals (A2 size) and 1 user’s manual on CD-ROM.
The 4 user’s manuals in hardcopy format describe the operating procedures required for basic use. It is recommended that
you refer to these user’s manuals to understand [1] installation, [2] initial settings, [3] program settings, and [4] operating
procedures of the controller.
The CD-ROM contains an User’s Manual (Reference) with descriptions of various functions and setting ranges that can be

This manual describes examples of setting PV input types, control output types, and alarm types. Carrying out settings
described herein allows you to perform basic control. Refer to examples of various settings to understand how to set parameters required. Refer to “1. Parameter Map” in Parameters User’s Manual for an easy to understand explanation of
setting various parameters. If you cannot remember how to carry out an operation during setting, press the

The UT350/UT320 controllers have a maximum of four target setpoint (SP) parameters and has PID for each of these
setpoints. The following shows the correspondence between the target setpoint numbers (SP.NO), target setpoints (SP), and
PID parameters.
For example, if you have set “2” to the target setpoint number (SP.NO), the control parameters available are target setpoint
(2.SP), proportional band (heating-side proportional band) (2.P), integral time (heating-side integral time) (2.I), derivative
time (heating-side derivative time) (2.D), cooling-side proportional band (2.Pc), cooling-side integral time (2.Ic), and cooling-side derivative time (2.Dc).
To use multiple target setpoints, see the table below to check the corresponding parameters.

• The UT350/UT320 controllers have a universal output.
The type of control output can be set/changed using the parameter “OT”.
At this point, the controller must be wired correctly according to the selected type of control output. Check the wiring
first if the controller provides no control output. To do this, refer to “6. Terminal Wiring Diagrams,” in Installation
User’s Manual .
With the parameters “OH” and “OL”, it is possible to set/change the high and low limits of control output. The control
output may not change at all, however, because of restrictions on these parameters. Also check the restrictions on these
parameters.
• The control output can only be changed when the controller is in the MAN mode.

● The control output does not change soon after the target setpoint SP has been

• If this happens, check the setpoint of the parameter “C.MD”. In cases where fixed-point control is selected as the PID
control mode (C.MD = 1), tracking based on the I-term works to prevent the control output from changing suddenly
even if the target setpoint SP is varied.
The control output therefore may appear to be working incorrectly at first; however it gradually adapts itself to the new
target setpoint.

to their stand-by state, however.)
• Setting parameters that have already been configured retain their settings.

• After recovery from a power failure, control action resumes in the same mode as the one before the occurrence of the
power failure. The control output begins with the preset output value.
• The UT350/UT320 controllers have a universal input.
The type of PV input can be set/changed using the parameter “IN”. At this point, the controller must be wired correctly
according to the selected type of PV input. Check the wiring first if the controller fails to show the correct PV. To do
this, refer to Initial Settings User’s Manual .
With the parameters “RH”, “RL”, “SDP”, “SH” and “SL”, it is possible to scale the input signal and change its number

In heating/cooling control, the controller outputs the result of computation after splitting it into heating-purpose and cooling-purpose signals.
In addition, the controller can perform PID control or on-off control on the heating and cooling sides separately. When performing on-off
control, set the proportional band to “0”.
The controller splits the result of computation (0 to 100%) into heating-side and coolSP

Precautions in Heating/Cooling Control
• Keep the ratio of the heating-side proportional band (P) to the cooling-side proportional band (Pc) equal to or below 5.
• If neither the heating side nor the cooling side is performing on-off control, setting the integral time (I or Ic) of one side to “0” results in
the Integral Time parameters of both sides being set to “OFF”,
irrespective of the integral time setting of the other side.

Using a zone PID, you can automatically switch between groups of PID constants according to the temperature zone. You can set a maximum
of three temperature zones.

If the target setpoint before switching is smaller than the target setpoint 2.SP=640°C
after switching, the controller operates according to the settings of the
140°C
Setpoint Ramp UP (UPR) and Ramp Time Unit (TMU) parameters. If the
temperature difference
target setpoint before switching is greater than the target setpoint after switch70°C/min
ing, the controller operates according to the settings of the Setpoint Ramp
(140°C/2 min) rate of
Down (DNR) and Ramp Time Unit (TMU) parameters. The figure on the 1.SP=500°C
temperature change
right shows an example when the Target Setpoint Number (SP.NO) param2-minute interval of
eter is switched. The 1.SP and 2.SP parameters are set to 500°C and 640°C,
temperature rise
respectively. Thus, there is a temperature difference of 140°C between the
Switching from 1.SP to 2.SP parameter
1.SP and 2.SP parameters. This example shows how the temperature is
changed by as much as this temperature difference over a period of two minutes. In this
NOTE
example, the UPR parameter is 70°C and the TMU parameter is 1 minute.
When using target setpoint ramp setting function, PV tracking works
Setting Method:
[1] Set the Zone PID Selection (ZON) parameter to
“ON”.
[2] Define a reference point.
When using two zones, define only reference point 1
(1.RP) between the minimum and maximum values of
the PV input range.
When using three zones, define reference points 1 and
2 (1.RP and 2.RP) in the same way as noted above.

to automatically set the optimum PID constants. This

A cycle time can only be set if the type of control output is time proportional PID relay output or time proportional voltage pulse output.
A cycle time refers to one period consisting of on- and off-state time
lengths. The ratio of the on-state time to the off-state time differs according to the value of the control output. The figure on the right shows
on-to-off time ratios of the control output when the cycle time is set to
10 seconds. Setting a shorter cycle time allows the controller to perform
elaborate control at short time intervals. This significantly reduces the
on- and off-state times, however it shortens the service life of a relay.
