I want to output the results of calculations by ladder programs with 4-20 mA on the OUT output terminal, but nothing happens.

(ns-faq-ut-2207-program)

For analog output of calculated results to the OUT terminal, set the output selection type OT to 00.00 and the transmission output type 01RS to OUT1.

I want to output the results of calculations by ladder programs with 4-20 mA on the RET output terminal, but nothing happens.

(ns-faq-ut-2208-program)

For analog output of calculated results to the RET terminal, set the transmission output type RTS to OUT1.

I want to output the results of calculations by ladder programs with 4-20 mA on the OUT2 output terminal, but nothing happens.

(ns-faq-ut-2209-program)

For analog output of calculated results to the OUT2 terminal, set the first two digits of the output selection type OT to 00, and the transmission output type 02RS to OUT1.

Is the SP slope valid for remote SP values as well?

(ns-faq-ut-2210-spec)

Yes.

I want to contol pressure and temperature with a single pattern using the UP and UT.

(ns-faq-ut-2213-spec)

You can do this with the pattern 2 transmission function. With the program pattern 2 transmission function, you can create and transmit program patterns at the same time, aside from program patterns used in control.

When installing the UTAdvanced series, what is the depth in millimeters from the surface of the panel?

(ns-faq-ut-2214-spec)

65 mm. For details, see the specifications of individual models.

Can I use DO to transmit the SP number currently used on the UT to an external device?

(ns-faq-ut-2215-setting)

Yes. Assign an I relay to the DO parameter.

Can I switch heating and cooling control?

(ns-faq-ut-2218-spec)

Yes, by using PID switching. Generally, you set heating control to reverse action and cooling control to direct action.

Can I connect multiple instruments such as power controllers to a controller's analog current output?

(ns-faq-ut-2219-connect)

Yes, as long as the total input and wiring resistance of the connected instruments is 600 Ω or less.

I’ve coordinated operation between 2 UT's via RS485 communication. I want to compensate the SP value of the child UT but is that possible?

(ns-faq-ut-2224-setting)

Yes. Set remote ratio (RT) or remote input bias (RBS).

I wrote the alarm setting values from the UT350 to the UT35A via communication. On the UT350, the alarm setting values were common from 1SP through 4SP, but when updating to the UT35A, what should I do?

(ns-faq-ut-2231-spec)

Use the GREEN compatible registers DO231 (alarm 1 setting) through DO233 (alarm 3 setting). Ex.) DO231: A1_G (setting value of alarm 1 for GREEN) Write the values written to A1_G to A1_L1_1 through A1_L1_4. A1_L1_1(D2504) A1_L1_2(D2524) A1_L1_3...

Do you sell terminal covers?

(ns-faq-ut-2233-other)

Yes. Model: UTAP001 Supports: UT75A, UT55A, UT35A, UP55A, UT35A Model: UTAP002 Supports: UT52A, UT32A, UP32A, UM33A

To prevent mis-operation, is there a setting where you hold down the A/M button to switch the operation?

(ns-faq-ut-2240-setting)

Not with parameter settings, but you can do this with a ladder program.

Can I set it for 1 shot-only event display and contact output ON when an alarm activates?

(ns-faq-ut-2241-setting)

Not with parameter settings, but you can do this with a ladder program.

Is it possible to connect multiple contact inputs to a single relay contact?

(ns-faq-ut-2243-connect)

No, use 1 contact per input. If you connect multiple inputs, when you turn OFF the UT, the impedance lowers and mis-operation can result.

Can I choose the color of the UTAdvanced terminal cover?

(ns-faq-ut-2246-spec)

No, it only comes in white.

Is the current transformer for heater current measurement that is used by UTAdvanced made by Yokogawa Electric?

(ns-faq-ut-2247-other)

It’s from U-RD. Please purchase them from our dealers.

What is the model of the current transformer for heater current measurement used by UTAdvanced?

(ns-faq-ut-2248-spec)

Recommended CT:U-RD CTL-6-S-H: CT ratio 800, measurable current range: 0.1-80.0 Arms CTL-12L-30: CT ratio 3000, measurable current range: 0.1-180.0 Arms

How can I display the currently used PID no. on the operation screen?

(ns-faq-ut-2249-setting)

Turn OFF the U.PID parameter symbol in the setup parameter KLOC menu.

Can I set control for power fail recovery to MAN?

(ns-faq-ut-2117-setting)

For a power failure of approximately 5 seconds or more, you can do this with the restart mode R.MD setting. For power failures of less than approximately 5 seconds, the control operation prior to the power failure continues. ...
