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 param-
eters 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

S E T / E N T

key for

more than 3 seconds. This brings you to the display (operating display) that appears at power-on.

Name of Part

Function

A/M key

Used to switch between the AUTO and MAN modes. Each time you press the key, it switches to
the AUTO or MAN mode alternately.

SET/ENT
key

S E T / E N T

Used to switch or register a parameter. Pressing the key for more than 3 seconds allows you to switch
between the operating display and the menu for operating parameter setting display alternately.

Used to change numerical values. On setting displays for various parameters, you can change
target setpoints, parameters, and output values (in manual operation). Pressing the key
decreases a numerical value, while pressing the key causes it to increase. You can hold
down a key to gradually increase the speed of change.

and
keys

Process variable (PV)
display

Displays PV.
Displays a parameter symbol when you set a parameter.
Displays an error code (in red) if an error occurs.

Setpoint display

Displays the setpoint (SP) or the output value (OUT) during operation.
Displays the set value of parameters on the parameter setting display.

Target setpoint (SP)

When the SP number currently used for operation is 2, 3 or 4, the respective SP No. indicator lamp lighits.
When the SP number is 1, the lamp does not lighit.

Status indicator lamp

Is lit in green during manual operation. MAN: Is lit when in manual mode.

Alarm indicator lamps

If any of alarms 1 to 3 occurs, the respective alarm indicator lamp (AL1 to AL3) is lit (in orange).

Light-loader interface

Interface for an adapter cable used when setting and storing parameters from a PC.
This requires an optional parameter setting tool.

IMPORTANT

The controller automatically returns to the display at the time of power-on (i.e., operating display) if no key is
operated for at least one minute.

Although only figures of the UT350 front panel are cited in “2. Setting PV Input Type (Setting First at Power-on),” and
thereafter, the UT320 is identical to the UT350 in terms of front panel operation.

2. Setting PV Input Type (Setting First at Power-on)

NOTE

•

The controller displays the operating display when the power is
turned on. However, if PV input type has not been set, “IN”

appears. In this case, first use the

key to display the input

S E T / E N T

key to register it. Then,

set the maximum value (RH) and minimum value (RL) of the
PV input range (for voltage input, set the maximum value (SH)
and minimum value (SL) of the PV input scale).

•

The controller is configured to the initial value of each parameter at the factory before shipment.
First check the initial values shown in “2. Lists of Parameters,” in

Parameters User’s Manual

and change

parameter values as necessary.

6. Description of Multiple Setpoints and PID

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 cool-
ing-side derivative time (2.Dc).
To use multiple target setpoints, see the table below to check the corresponding parameters.
