Overview:

Taking advantage of sensors already available in your system, you can simply add VJ series signal conditioners or the UM33A Digital Indicator with Alarms to easily build a monitoring system on a PC.

Overview:

The UM33A Digital Indicator with Alarms is a digital panel meter with an easy-to-read white LED. Combining the features below, it can be used as a digital indicating controller for control rooms, and instrumentation panels in process automation sites.

Overview:

Check site conditions while monitoring temperature and humidity of the production line and storehouse.

PEAK and BOTM are not setting parameters. They are the maximum and minimum values of the measurement input (PV), respectively.
Try the 10-segment linearizer approximation function.
Use the Select Screen function. Up to 5 select screens can be configured. Assign parameters CS1–CS5 to Alarm1:2351 through Alarm8:2358.
Yes. Set the input range to 0-10 V. Short the input terminal (terminal no. 202-203). If you write the value to the parameter's bias (BS) item, it is reflected to the PV value. Note, the profile is overwritten so you need the LL50A.
Try the broken line function. That function comes with the UT52A, UT55A, UT75A, UP55A, and UM33A.
This is supported on the UT75A, UT55A, UT52A, UP55A, and UM33A by using the 10-segment linearizer function.
You can use this with suffix codes /LP, /L1, /LCH, /L4, and /LC4. For wiring to a 2-wire transmitter, the controller is equipped with an insulated sensor power supply (21.6 to 28.0 VDC). ...
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.
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...
We have the UT52A/UT32A/UP32A in the UTAdvanced series. For an indicator with alarms, we have the 96 x 48 sized UM33A.
Autotuning is performed when you turn AT_L1 in the OUT area to ON (= set to 1). Please make sure that AT_L1 in the OUT area turns OFF (= set to 0) after autotuning is finished.
When writing individual parameters via CC-Link communication, if the data values to write are not different from the existing ones, overwriting of the values does not occur. If you write all parameters by individual communication address and the valu...
BR is the communication speed for CC-Link. BPS is the communication speed for the Modbus master function (RS485).
b.out indicates a burnout on the measurement input. It appears when measurement input wiring is disconnected. Check the sensor and wiring.
Use a current generator with a SINK function (transmitter simulation).
Proportional band P has data of up to 1 decimal point. By contrast, communication data has no decimal point. If you want to write 100.0% to P, send 1000. For differential and integral time, the data has no decimal point.
Turn OFF the U.PID parameter symbol in the setup parameter KLOC menu.
No. Only the conventional CC-Link Ver. 1.1 or 2.0 standards are supported.
If outside of the parameter setting range, data is not written.
When the writing flag (RX1) is ON, the next write process can't proceed. Make sure the writing flag (RX1) is OFF before performing a write process.
Autotuning is performed when you turn AT_L1 in the OUT area to ON (= set to 1). Please make sure that AT_L1 in the OUT area turns OFF (= set to 0) after autotuning is finished.
RUN/STOP is set to contact input DI2 by default, and takes precedence over communication. Set S/R to OFF with DI.SL.
If not using relay contact output for control, you can use it as a 4th alarm. This alarm would be the C contact type, therefore by connecting it to the N.C. (normal close) side you can use it as an alarm terminal. Note that when changing the basic sp...
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...
If you connect a shunt resistance to the input terminal of the receiving side meter, you can input it as voltage. For example, if you connect a 250 Ω shunt resistance to 4–20 mA output, it's 1–5 V. Make the resistor, including the wiring, t...
You can change it if it is in a user profile (profile no. 0).To create a user profile, use the LL50A network profile tool.
Use profile number 0. You can also use CCLink even if you delete the parameter assignments of Modbus slave 2 from the user profile.
No, a UT100 series instrument cannot connect. Only other UTAdvanced series instruments can connect.
It allows communication with RS-485 compatible UTAdvanced series instruments via CC-Link. It allows acquiring data from downstream controllers that do not have CC-Link communication, and writing parameters.
See the UTAdvanced Series Communication Interface (RS-485, Ethernet) User's Manual.
Open registers for the number of proprietary stations per unit. For example, if there are 3 CC-Link Ver. 1 stations are occupied, the bit area occupies 96 bits per station and a word area of 12 words per station. If the refresh device of the word ar...
The output is restricted to a lower limit of 3.2 mA (-5%) and an upper limit of 20.8 mA (105%), but only when the transmission output scale RTH and RTL settings are the same as the PV input range.
At DC24 V: Approximately 17 A, 1.5 ms At AC100 V: Approximately 4.5 A, 3 ms At AC240 V: Approximately 11 A, 3 ms
Per the specifications, the accuracy of type K at 0°C or higher is ±0.1% ±1 digit. The measuring range in this case is that of the selected input type, -270.0 to 1000.0. You can calculate the accuracy as follows. ±0.1% of 127...
It is approximately 0.16 mA.
“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 the...
Yes. Set the following: IN=1-5V, RH=1.000, RL=5.000, SDP=2, SH=0.00, SL=-10.00.
Set alarm types AL1–4 or 8 (ALRM operation parameter) to 0.0.0.00.
Use a relay that supports miniscule currents. The minimum ON current of a contact input (DI) is approximately 1 mA.
Check the key lock. If you see the R.SP display, in Remote mode (REM), that means SP is being set by an external (upstream, etc.) device and cannot be changed.
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
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.
No, it only comes in white.
The UTAdvanced series are not subject to the CCC standard. They can be used in China.
65 mm. For details, see the specifications of individual models.
You cannot apply an external voltage. You can connect either a no-voltage contact or a transistor contact.
Q: I'm connecting a UT with CC-Link communication to another downstream UT via RS485 communication (Modbus master function). However, the RS485 communication terminal of the UT with CC-Link communication is a 2-wire system, and that of the other ...
When you turn ON the power, it shows up on the self-diagnostic screen that appears for a few seconds. The 3-digit number in the SP display section is the basic suffix code. (Ex.) For the UT55A-210-01-00, the number "210" appears.
Select the type that is closest to the temperature range span that you are using.
Yes. The data will be -1500–31500. For the OUT terminal output, D7621(OUT_OUT)For the RET terminal output, D7624(RET_RET)For the OUT2 terminal output, D7623(OUT_OUT2L)
The display is blank if you turn ON the power while a a dedicated LL50A cable is plugged into the maintenance port. Try removing the cable and restarting.
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.

Please see the parameter map for your specific model. UTAdvanced Series Parameter Maps and Lists
Yes. Use a UT link module for the FA-M3, and use PC link communications (RS-485) for the temperature controller communication protocol selection.
Program changes for reading PV and OUT, writing SP, and other basic parameters are not necessary. There are registers and relays that support the GREEN series. For details see the UTAdvanced series communication interface (RS-485, Ethernet) user'...
There might be breakage in a line. Check input wiring and sensors.If the input is restored, B.OUT will be cleared automatically.
They are set with the same industrial quantities as the input units.
Yes, as a percentage of the PV input range span or output span.
For communication errors, the left side decimal point of the symbol display on the main unit blinks. If the SD or RD indicators light on upstream devices, check whether both are blinking.
What is the alarm standby function?
(ns-faq-ut-2111-spec)
Standby means that even when an alarm condition occurs it is ignored and the alarm stays off until the alarm condition ends. When the signal enters a non-alarm region, standby mode ends. Standby works in the following situation. When powering onWhen...
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.
