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: ZAC2205-00U
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 the possibility of being struck by external lightning surge, use the arrester to protect the instrument.

4. How to Connect Wires
1) Before carrying out wiring, turn off the power to the controller and check that the cables to be connected are not
alive with a tester or the like because there is a possibility of electric shock.
2) For safety, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to
IEC60947) near the controller so as to be operated easily, and clearly indicate that the device is used to deenergize the controller.
3) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.

6. Troubleshooting
■ Troubleshooting Flow
If the operating display does not appear after turning on the controller’s power, follow the measures in the procedure below.
If a problem appears complicated, contact our sales representative.
Comfirmation
If your control tasks are not successful, check the preset parameters and controller wiring before concluding the controller
to be defective. The following show examples of troubleshooting you should refer to in order to avoid the possibility of
other problems.

• The UT350L 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
of decimal places. Also check that these parameters are configured correctly.
7. Cleaning and Maintenance
Find the cause.
Use a dry cloth and wipe gently to clean the product’s front panel, keys, and other areas.

Changing the registered value of a setup parameter
may cause the registered value of an operating parameter to be initialized automatically. Thus, when
you have changed a setup parameter, always check
that the registered value of the operating parameter
is appropriate. If it is initialized to default, reset it to
the required value.

The state of output relay at power-on can be set by a setup parameter restart mode R.MD.
■ In Case of High Limit Control
When a measured value (PV) exceeds a setpoint (SP). “EXCEEDED” lamp lights, and “OUT” lamp turns ON (point A). The limit control
output relay is de-energized then.
“EXCEEDED” lamp turns off when PV goes into normal condition, while “OUT” lamp stays on as it is (point B). “OUT” lamp turns off
when a confirming operation is done by an operator (point C). The way to confirm is pushing the “RESET” key (or by an exeternal contact,
according to the setting of setup parameter DIS). The confirming operation is not accepted during PV exceeds SP (point D). State of output
relay is de-energized whenever “OUT” lamp is on. (NC terminal : CLOSE, NO terminal : OPEN)

Restart mode R.MD :
0 : Limit output relay is de-energized at power on.
1 : Limit output relay is energized at power on.
The time while PV exceeds SP is counted and stored in the memory. It is displayed in the “TIME” display in the confirmation display.

- To RESET
- Push “RESET” key for about one second to reset the duration time in the confirmation display where “TIME” is displayed.
When the count are reset, “0.00” is displayed until PV exceeds SP again.
- The time count are reset when power is turned on.
- If PV exceeds SP during the old time count data is retained in the memory, the old data should be automatically reset, and the
new time counting starts from “0.00”.
- It is impossible to reset the time count while PV exceeds SP by any operation.
- Duration time cannot be reset by an external contact input.

The limit output relay is always de-energized at power on, even if PV doesn’t exceed SP (point A). (NC terminal : CLOSE, NO terminal :
OPEN). “OUT” lamp is lit. After the confirmation, state of output relay is energized (NC terminal : OPEN, NO terminal : CLOSE) and “OUT”

■ Maximum / Minimum Value
SP
The maximum value or minimum value of PV is stored in the memory and display in the “HI” or “LO” display in the confirmation display.
When the control type is specified as high limit control, the maximum value is displayed in the “HI” display, and control type is specified as
low limit control, the maximum value is displayed in the “LO” display.
When the PV exceeds SP and then returns to the normal status, Maximum / Minimum Value is retained as it is , but when PV exceeds SP again,
it is automatically reset and starts taking new value for its minimum / maximum value.
