Overview:

In the plants of food and beverage manufacturers, there are times when monitoring and recording of production equipment is necessary inside clean rooms. This is an introduction to monitoring and recording in clean rooms using paperless recorders.

Industries:
I'm editing a CC-Link communication profile on the LL50A. I want to add the UT32A-D type to the RS485 communication line, but the PV2 register symbol doesn't appear.
(ns-faq-ut-2168-setting)
Select Modbus slave device UT32D.
I just purchased the UT and UM and the EV lamp turned ON. What does that mean?
(ns-faq-ut-2157-setting)
Per factory parameter settings, the EV lamp on the UT and UM is assigned to alarms, and may light depending on the measured input (PV) and setting values. Configure your EV lamp and alarm type settings to match your operating conditions.
I want to create a ladder program that writes output tracking values via communication.
(ns-faq-ut-2158-setting)
In your ladder program, use variable register P01 and others, and write the P01 value via communication. Then do a MOV of the P01 data to the tracking input value (TRK_CTL).
With 1-5 VDC input, can I make the PV display 0.00 to -10.00 kPa?
(ns-faq-ut-2156-setting)
Yes. Set the following: IN=1-5V, RH=1.000, RL=5.000, SDP=2, SH=0.00, SL=-10.00.

Perform tuning with these reference values: P=150 to 200, I=10 to 20, D=OFF.
I'm using a thermocouple for the input, but "b.out" appears on the PV display. What should I check first?
(ns-faq-ut-2160-other)
“b.out” on the PV display indicates a break in the input. Check whether the signal from the sensor is getting through. Also, to narrow down the cause, you can short the input terminal of the UT itself, then if the UT's input is normal...

(ns-faq-ut-2145-setting)
Try the PV tracking function (PVT=ON). This function is useful for preventing sudden changes in the PV value. When operation starts, the PVT starts by matching SP to PV, and then uses an SP slope function (TMU, UPR, DNR) to gradually return SP to the...
I'm controlling temperature by using voltage pulse output to operate a heater with an SSR, but I can't stop the hunting. I already performed auto-tuning.

By factory default settings, the PID number is linked to the SP number. You can change the setting with the zone PID selection parameter (setup parameter CTL > ZON).
I'm replacing my GREEN series with the UTAdvanced series. Is there anything I need to be careful of in terms of wiring?
(ns-faq-ut-2108-connect)
The common for all GREEN series alarm relay outputs are shared. In the UTAdvanced series, each alarm relay output has its own common. If used the same way, use external wiring to connect common to common.
Can I acquire trend data on the LL50A?
(ns-faq-ut-2053-soft)
You can display and acquire PV, SP, and OUT values as trend data. The trend data you acquire can be saved as a CSV file.
Can I set the PV display to -100 with 20 mA input, and to 0 with 4 mA input?
(ns-faq-ut-2089-setting)
In this case, 20 mA is the minimum value of PV input, and 4 mA is the maximum. In the setup parameter PV menu, set RH=4.00 and RL=20.00 (the input range maximum and minimum values). For the PV input scale max, min, and decimal place, set SH=0, SL=-10...
Is there an easy way to change the settings for alarms 1 and 2?
(ns-faq-ut-2062-spec)
If you register the A1 and A2 parameters (for setting alarms 1 and 2) to the select screen, you can display the alarm 1 and 2 settings simply by pressing the DISPLAY key repeatedly. Set the CS1 and CS2 select screen parameters to "2504" and...
Is a terminal cover included?
(ns-faq-ut-2088-select)
The UT52A, UT55A, UP55A, and UT75A come standard with terminal covers. For the UT32A, UT35A, UP35A, UP32A, and UM33A, specify the /CV option when order on or after May 31, 2015. They are also sold separately. Models: UTAP001UT75A, UT55A, UT35A, UP55A...
Are all COM terminals for contact input connected internally?
(ns-faq-ut-2061-spec)
Yes.
To cause setpoints (SP) to change at a fixed rate, I set the SP ramp up and down parameters (UPR and DNR). Is this function still enabled when changing the SP value through remote input (RSP)?
(ns-faq-ut-2058-spec)
Yes. The SP ramp up (UPR)/SP ramp down (DNR) function supports changing the SP value with the UT55A front panel buttons or remotely.
Can I switch scaling using contact input?
(ns-faq-ut-2054-program)
Yes. Use the SCAL ladder program command.
What is the resolution of control output (4–20 mADC)?
(ns-faq-ut-2055-spec)
It is 1/20000. That is equivalent to approximately 14.5 bits.
How can I enter initial settings?
(ns-faq-ut-2064-setting)
Please see an operation guide. Controller operation guides are available for standard and detailed models. (Ex.: UT55A-000-01-00 is a standard model, and UT55A-NNN-01-AN is an detailed model). Note that you can refer to the user's manual for any ...
Can I reverse the 4–20 mA control output and change to a 20–4 mA signal?
(ns-faq-ut-2063-spec)
Yes, the output signal can be reversed. In the setup parameter OUT menu, set the OU.A parameter to "20–4."
OVER was displayed on the PV (measured value) display. How will the control output operate in this case?
(ns-faq-ut-2070-spec)
If OVER is displayed, the PV value will be 105% of the measurement range. The control output will be the result that is calculated using this PV value. On a -OVER, the PV value is calculated as -5% of the measurement range.
Can I switch the temperature units between°C and °F?
(ns-faq-ut-2087-spec)
Per the metering law, in Japan you can only use °C. For customers who require overseas-specification products that can display Fahrenheit for embedding in a device exported outside of Japan, please contact your dealer or Yokogawa representative. ...
There are differences between PV display values and the displays of other measuring instruments. Can I correct these?
(ns-faq-ut-2078-spec)
Yes, by using PV input bias (parameter BS).
An error occurs with position-proportional type automatic valve position adjustment (V.AT).
(ns-faq-ut-2083-setting)
(1) Check the wiring: In MAN mode, set OUT display. Use the UP and DOWN keys to confirm operation of the control valve, and that the OUT value changes. The UP key operates the normal rotation side relay, and the DOWN key operates the reverse rotation...
I initialized the controller, but no control output value is output.
(ns-faq-ut-2074-setting)
The controller's operation may be set to START/MAN. Check the controller operation indicator on the front panel.
B.OUT was displayed on the PV (measured value) display. What could be the cause of this?
(ns-faq-ut-2077-connect)
There might be breakage in a line. Check input wiring and sensors.If the input is restored, B.OUT will be cleared automatically.
How can I use control relay output as an alarm relay (alarm 4)?
(ns-faq-ut-2011-setting)
As an example, we describe how to use Control relay as Alarm output 4 (Deviation low limit). 1. Setting Setup Parameter   1-1. Set OT(Output type selection) to other than OT=00.03        ex) OT=00.02 (Cur...
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. ...
What is the model (part number) of the UTAdvanced series mounting brackets?
(ns-faq-ut-20030-select)
The part number for the entire series is L4502TP. It comes in a set of 2.
