Highly functional 1/4 DIN sized Controller comes with Custom Computing and 12 powerful control functions including dual-loop control. It also features easy-to-see large PV display and LCD display for interactive setting and programming. The universal I/O, auto-tuning, "SUPER" and "SUPER2" functions are standard. Two ports of RS-485 communication are option.

This is because the unit of the controller's user parameter differs from the unit specified in the parameter setting tool. You will have to either use the unit from the controller on the parameter setting tool, or use the custom computation building ...
The DI settings are made unavailable to protect the DI connection set in the custom computation tool. (in the same manner, the controller main unit also skips the display) If you want to change the U*M=21 DO, use the custom computation creation tool....
Not by the user. Repair support of these products have already ended, so please consider updating to the UTAdvanced series.
Even when you expand the applicable range of the PID constant, the process states fluctuate, or response is unstable and hunting occurs (control responses fluctuate), this function is effective for stabilizing control and suppressing hunting. Normall...
Is there any sample custom computation data?
Sample data is available for each control mode. We recommend that you modify these samples to create your own.
The DO settings are made unavailable to protect the DO connection set in the custom computation tool (in the same manner, the controller main unit also skips the display) If you want to change the U*M=21 DO, use the custom computation creation tool....
What is custom computation?
When using basic math, you can apply any correction to the input. When using logic, you can incorporate sequencing between the input and output contacts. Analog sequencing is also supported.
Can I order a custom computation?
No. Customers will need to create these themselves.
The software program LL200 (sold separately) is required for the UT750/UP750, and LL1200 (sold separately) is required for the US1000.
With a UP program controller or UT digital indicating controller as the parent station and multiple UT digital indicating controllers as the child stations, the children perform the same actions that are carried out on the parent. ...
What models support custom computation?
UT750, UP750, and US1000-x1.
For single-loop models such as the UT351, up to 16. For 2-loop control on the UT750, up to 8.
No, there is no conversion tool, but note that custom calculations can be replaced with ladder sequence programs. See (TI 05P01B41-03EN): “Conversion Table of UT750 Custom Computation into UT75A Ladder Program.”...
It is a one shot contact.
Can I set 5 alarms or more?
Yes, if using alarms within the upper/lower limit difference.
Can I change the alarm output terminal?
Yes, by changing assignments in the registered contact output parameters (UT500/UT700 only).
If you set the registered contact input parameters to SP.0=5353 and SP.1=5545, you can select 1SP with ON and 2SP with OFF.
This is possible with the UT500/UT700. With the registered contact output parameters, assign relay number in each mode.
What is the output upon reset?
It is the preset output.
This happens when SP tracking is turned ON in the setup parameters. Turn this parameter (SPT) OFF.
Yes. Use 1SP, 2SP, 4SP, and 8SP.
Yes, by setting RET=3(OUT). (Note that this is position proportional only.)
Can I control chemical dosing?
The auxiliary analog input function supports this with a ratio bias function.
This is supported on UTAdvanded series UT52A / UT55A / UT75A / UP55A.
This is a function in which output occurs a specified time after an alarm set point is exceeded. If you clear the alarm point during operation of the timer, the timer is reset.
Yes. The selection in the OT=0 to 3 setting in the setup parameters will be 1 output.
When switching with contacts, communication cannot be used.
Once input is set, IN is not displayed when you turn the power ON.
This function supplies power to 2-wire transmitters. It differs depending on the specifications of the transmitter, but the input accepts 100 Ω resistors. 100 Ω resistor (model: X010-100-2, sold seperately)
The DO206 items are used when in cascade control mode. For other modes, use DO201.
Set the following: P=100, I=D=OFF, DR=DIR (direct action), MR=0, SP=0.
Yes, if it is a heating/cooling type.
There is no control output.
Check whether MAN operation (manual) is selected for the output.
Why don't PID items appear?
They don't appear with OT=3 ON/OFF control.
Check whether you can output manually. If not, check wether OL (cooling output limiter)=100%.
I can't switch the SP.
Check whether you are trying to switch it via communication, or whether it is the zone PID.
With the UT300 series, only use 1PID. With UT400/500/700 models, the PID used just prior to switching to remote input is used. When using SP switching during remote input, only the PID switches.
What are the PID switching methods?
There is a zone, contact, and parameter switching method.
Can I perform CC-Link communication?
Yes, by using the UTAdvanced series.
Output stops when the status is STOP.
When RET=1 or 2, the STOP has no effect.
How many PID groups can be used?
4 groups for the UT300 series, and 8 groups for the UT400/500/700 series.
DO215, used for communication, is not backed up.
Set both item P on the heating side and item Pc on the cooling side to 0.0.
If you set + dead zone in the settings, you can get an area where no outputs occur. If you set - dead zone, you can get an area where both outputs occur at the same time.
Check that the operating parameters UPR and DNR are both OFF.
This is a limit on the number of times you can write to the element used (EEP-ROM).
Set them in the order, Alarm type → Alarm setting values. They will also not be displayed if you select an alarm for which no value is set.
The PV value can be written by using the ladder sequence function of UTAdvanced series. However, when communication is interrupted, the PV value is retained.
It depends on the model. The following lists the readable registers by model. UT100 series: D0001–D0009 UT300 series: D0001–D0008 UT400/UT500/UT700 series: D0001–D0025 UP350: D0001–D0008 UP550/UP750: D0001–D0025 ...
There are 2 types of output available, FAIL and "failure diagnosis."
The output is 0% if there is a hardware failure such as an internal microprocessor.
The UT300/400/500/700 series, and the UP350/351/550/750. However, the LL200 custom computation function is only compatible with the UT750/UP750.
PCBs (polychlorinated biphenyl) were banned from manufacturing and imports in 1975. The GREEN series began to be manufactured in 1997, and do not include PCBs.
Check whether the wiring to the power supply terminal is correct. If only the LCD on the UT/UP700 does not display, a custom computation may be set for no display. If the PV display is also blank, this may indicate product failure. Please contact you...
If the operation mode is STOP or MAN, they are not displayed.
What are energize/de-energize alarms?
For energize alarms, ON contact results when an alarm occurs. For de-energize alarms, OFF contact results when an alarm occurs. Note that OFF contact also results when the power fails.
The sensor wire on the input side might be broken or disconnected.
No. When an alarm occurs, it automatically recovers if values enter the normal range.
Sample programs and dedicated communication materials are available for MELSEC-A/MELSEC-Q.
Do Green series controllers support Ethernet?
Yes. This requires an RS-485/Ethernet converter such as VJET. The controller must also have a communication option. Some models can be connected directly with the UTAdvanced series.
How do I change the input type?
If you change the input type, parameters will be initialized. We do not recommend that you make changes while in operation.
Yes, but if you change some parameters, others will be initialized. We do not recommend that you make changes while in operation.

Yes, the Auto tuning function.
These cannot be set when in Custom Computation mode.
Almost all items can be accessed, including PV reading, SP writing, and PID setting.
Ladder communication is used when communicating with the Computer link unit/Serial communication unit. Modbus/RTU is used for communication with the Modbus communication module.
What are direct and reverse action?
Generally, reverse action means heating control and direct action means cooling control. When output is reverse action, output is ON during PVSP.
600 Ω.
There is no current input range.
Use a resistor to input current as voltage. A resistor is available: X010-250-2 (250 Ω).
The are set with a real number. For temperature, it is set in degrees Celsius.
As for individually writing parameters via CC-Link, changing OUT area values constitutes a write request. In your case, since the OUT area value hasn't changed from the previous value, the SP value is notoverwritten. As a fix, periodically copy t...
