A long time has passed since the word "downsizing" was first coined. In the field of instrumentation, total cost reduction is continually being sought, with this trend becoming even more accelerated as a result of the present economic recession.
When U*M=21, I can only set the message text in the DI setting screen of the setup menu screen.
(ns-faq-green-9106-soft)
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....
What accessories are required for custom computation of UT750/UP750/US1000?
(ns-faq-green-9061-select)
The software program LL200 (sold separately) is required for the UT750/UP750, and LL1200 (sold separately) is required for the US1000.
When I write U*M=21 to the controller I get the message, "Could not write U1 user parameter due to U1 unit mismatch," and I can't set the user parameter setting value on the controller.
(ns-faq-green-9104-soft)
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 build...
When U*M=21, the DO command button in the setup menu screen is unavailable so I can't enter settings.
(ns-faq-green-9105-soft)
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. ...
Can I order a custom computation?
(ns-faq-green-9063-program)
No. Customers will need to create these themselves.

(ns-faq-green-9062-select)
UT750, UP750, and US1000-x1.
Is there any sample custom computation data?
(ns-faq-green-9065-program)
Sample data is available for each control mode. We recommend that you modify these samples to create your own.
What is custom computation?
(ns-faq-green-9060-term)
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 set 5 alarms or more?
(ns-faq-green-9077-spec)
Yes, if using alarms within the upper/lower limit difference.
Can I switch 1SP/2SP with one DI of UT520/UT550/UT750?
(ns-faq-green-9054-spec)
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.
The SP value was rewritten after switching from remote mode to local mode.
(ns-faq-green-9024-spec)
This happens when SP tracking is turned ON in the setup parameters. Turn this parameter (SPT) OFF.
Can I switch four SPs with two DIs of UT520/UT550/UT750?
(ns-faq-green-9055-spec)
Yes. Use 1SP, 2SP, 4SP, and 8SP.

(ns-faq-green-9029-spec)
Yes, by setting RET=3(OUT). (Note that this is position proportional only.)
Can I control chemical dosing?
(ns-faq-green-9023-spec)
The auxiliary analog input function supports this with a ratio bias function.
What is the delay timer in the alarm function?
(ns-faq-green-9074-term)
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.
I'm trying to do RUN/STOP via communication by writing 0/1 to DO205, but it's not working.
(ns-faq-green-9050-spec)
When switching with contacts, communication cannot be used.
Can I use a heating/cooling type of 1 output?
(ns-faq-green-9069-spec)
Yes. The selection in the OT=0 to 3 setting in the setup parameters will be 1 output.
When should I use sensor power supplies (affected models: certain Green series instruments)?
(ns-faq-green-9008-spec)
These are used when 2-wire transmitters are used in the field. They provide cost savings since they do not need to be purchased separately. 24 V (21.6–28.0 VDC, 30 mA MAX) sensor power supplies can be specified with the following models: UT551,...
Can you tell me about the 15 VDC transmitter power supply function?
(ns-faq-green-9030-spec)
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)
IN is not displayed the first time I turn the power ON.
(ns-faq-green-9013-spec)
Once input is set, IN is not displayed when you turn the power ON.
I'm trying to do AUTO/MAN via communication by writing 0/1 to DO206, but it's not working.
(ns-faq-green-9051-spec)
The DO206 items are used when in cascade control mode. For other modes, use DO201.
I can't switch the SP.
(ns-faq-green-9053-spec)
Check whether you are trying to switch it via communication, or whether it is the zone PID.
There is no control output.
(ns-faq-green-9085-spec)
Check whether MAN operation (manual) is selected for the output.
What settings can I use to get control output that is proportional to the input?
(ns-faq-green-9045-setting)
Set the following: P=100, I=D=OFF, DR=DIR (direct action), MR=0, SP=0.
Why is there no output on the cooling side?
(ns-faq-green-9068-spec)
Check whether you can output manually. If not, check wether OL (cooling output limiter)=100%.
Are there independent PIDs for heating and cooling?
(ns-faq-green-9070-spec)
Yes, if it is a heating/cooling type.
Why don't PID items appear?
(ns-faq-green-9044-spec)
They don't appear with OT=3 ON/OFF control.
Can you give me details on the "Super2" function? (Affected products:Green series)
(ns-faq-green-9003-term)
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...
What PID should be used for remote input?
(ns-faq-green-9025-spec)
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.
The SP data written via communication is deleted when I turn the power ON/OFF.
(ns-faq-green-9038-spec)
DO215, used for communication, is not backed up.
Output stops when the status is STOP.
(ns-faq-green-9031-spec)
When RET=1 or 2, the STOP has no effect.
What is the difference between + and - of the dead zone?
(ns-faq-green-9067-spec)
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.
When I set up alarm values the parameters are initialized and I can't enter the settings.
(ns-faq-green-9071-setting)
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.
Is ON/OFF available with heating/cooling control?
(ns-faq-green-9066-setting)
Set both item P on the heating side and item Pc on the cooling side to 0.0.

(ns-faq-green-9084-spec)
The output is 0% if there is a hardware failure such as an internal microprocessor.
Please provide information about PCB usage. (GREEN series)
(ns-faq-green-9125-spec)
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.
There is no indication on the display in the GREEN series.
(ns-faq-green-9082-spec)
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...
Can I write the PV value via communication?
(ns-faq-green-9048-spec)
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.
What should I do when b.out is displayed?
(ns-faq-green-9080-spec)
The sensor wire on the input side might be broken or disconnected.
What are energize/de-energize alarms?
(ns-faq-green-9076-term)
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.
Auto-tuning parameters (AT) don't appear.
(ns-faq-green-9043-spec)
If the operation mode is STOP or MAN, they are not displayed.
How do I change the input type?
(ns-faq-green-9014-spec)
If you change the input type, parameters will be initialized. We do not recommend that you make changes while in operation.
Can I change setup parameters while the instrument is running?
(ns-faq-green-9015-spec)
Yes, but if you change some parameters, others will be initialized. We do not recommend that you make changes while in operation.
Do Green series controllers support Ethernet?
(ns-faq-green-9009-connect)
