Number of outputs: 1 (terminals 16 - 17 ) Output signal: 4-20 mA DC Load resistance: 600 or less Output accuracy: 0.3% of span under standard operating conditions (23 2C, 55 10% RH, power frequency of 50/60 Hz) 24 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. 1 Signal Isolations • PV input terminals: Isolated from other input/output terminals.

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. Is the instrument defective? Confirm that the EXCEEDED lamp is off and the OUT lamp is lit. OUT status cannot be reset while the EXCEEDED lamp is lit. Yes No Totally inoperable? Ex.) SP=120.0, PV=115.0, Hysteresis=5 Is key operation faulty? Yes Yes No Is display faulty? No Is I/O signal faulty? Yes Is communication link faulty? No Yes Yes Displays PV. EXCEEDED lamp is off. Duration time display SET/ENT key SET/ENT When limit control type is set as high limit. (factory-set default) Check the key lock setting. Check the supply voltage. OUT lamp is lit. Confirmation Display key Check wiring on the power supply terminals. Displays target setpoint. When limit control type is set as low limit. Turn off power, and then turn it on again. Check the instrument’s I/O specifications. Correct errors. ■ Confirmation of Limit Status Limit control output and related parameter such as duration time and maximum / minimum PV value can be confirmed by a front key operation. It is possible to confirm limit control output by using external contact input. The way of confirmation is set by setup parameter DIS. Table blow shows the item which can be confirmed by front key or external contact input according to the setting of DIS. Minimum value display Item to be confirmed 2. Setting Target Setpoint (SP) The following operating procedure describes an example of setting 120.0 to a target setpoint. Bring the operating display into view (display appears at power on).

DIS parameter = DI Output relay KEY Able DI Disable KEY Disable DI Able Duration time Able Disable Able Disable Maximum / Minimum value Able Disable Able Disable Does the code include a communication option? No communication capability. Check the communication-related parameters. • 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. NOTE Check communication wiring. Check the specifications of communication counterpart. Correct? Ask the vendor for repair. No ● The controller does not show the correct measured value (PV). ■ Cleaning No No 1. Check the instrument's suffix code. Check the specifications of I/O counterpart for wrong polarity. Normal?

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) (B) (C) off lit on - Push the “RESET” key for about one second to reset the maximum / minimum value in the confirmation display where “HI” or “LO” is displayed. The value is reset, and the value immediately after the confirmation should be recognized as a maximum or minimum value. - When the power is turn on, the memory should be reset and the first PV should be recognized as maximum. - Maximum / Minimum value cannot be reset by an external contact input. - It is impossible to reset the maximum / minimum value while PV exceeds SP by any operation. off (A) (D) Target setpoint PV dispay RET RTH RTL Retransmission output HI.LO Limit control H PV or SP AL1 AL2 A1 A2 HY1 HY2 Alarm function Limit control output RET OUTPUT Current terminals 16 and 17 Relay terminals 1 , 2 and 3 AL1 on Confirmation (not accepted) Confirmation (accepted) (A) off lit off Output Relay Operation (RESET key or external contact input) lit SP RESET AL2 Alarm 1 Alarm 2 terminals terminals 6 and 7 5 and 7 Power on Confirmation (accepted) Confirmation (accepted) Terminal Parameter Function Analog signal Contact signal Front panel key Legend ● When parameter R.MD is set to 1.
