Yokogawa ut750 manual

Sample data is available for each control mode. We recommend that you modify these samples to create your own. 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? What is assisted operation? Affected products: Green series ns-faq-greenterm. 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? How many units can I connect and monitor at the same time? For single-loop models such as the UT, up to For 2-loop control on the UT, up to 8. Is there a tool for changing parameters and custom calculations when upgrading from the UT to the UT75A?

No, there is no conversion tool, but note that custom calculations can be replaced with ladder sequence programs. Or is it a status contact? Can I set 5 alarms or more? Can I change the alarm output terminal? If you set the registered contact input parameters to SP. Can I set the operation mode to DO and then perform contact output? With the registered contact output parameters, assign relay number in each mode. What is the output upon reset?

The SP value was rewritten after switching from remote mode to local mode. This happens when SP tracking is turned ON in the setup parameters. Can I output an opening aperture signal from a valve? Note that this is position proportional only. Can I control chemical dosing? The auxiliary analog input function supports this with a ratio bias function.

On what models can the SP value can be changed with external analog signals? What is the delay timer in the alarm function? 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. IN is not displayed the first time I turn the power ON. Can you tell me about the 15 VDC transmitter power supply function? This function supplies power to 2-wire transmitters.

The DO items are used when in cascade control mode. For other modes, use DO What settings can I use to get control output that is proportional to the input? Are there independent PIDs for heating and cooling? There is no control output.

Why don't PID items appear? Why is there no output on the cooling side? Check whether you can output manually. I can't switch the SP. Check whether you are trying to switch it via communication, or whether it is the zone PID. What PID should be used for remote input? What are the PID switching methods? Can I perform CC-Link communication? Output stops when the status is STOP. How many PID groups can be used? Set both item P on the heating side and item Pc on the cooling side to 0.

If you set - dead zone, you can get an area where both outputs occur at the same time. What is the write limit of , times? When I set up alarm values the parameters are initialized and I can't enter the settings.

They will also not be displayed if you select an alarm for which no value is set. Can I write the PV value via communication? However, when communication is interrupted, the PV value is retained. What registers are accessible in UT link's Auto mode? It depends on the model.

The following lists the readable registers by model. Are contacts still good during malfunction? There are 2 types of output available, FAIL and "failure diagnosis. Is control output available on a failure? Please provide information about PCB usage. PCBs polychlorinated biphenyl were banned from manufacturing and imports in Carrying out settings described herein allows you to perform basic control.

Refer to examples of various settings to understand how to set parameters required. If you cannot remember how to carry out an operation during setting, press the DISP key no more than four times. This brings you to the display operating display that appears at power-on.

Power-on Denotes a step that must always be followed. Denotes a step that should be followed as necessary. If any of alarms 1 to 4 occurs, the respective alarm indicator lamp AL1 to AL4 is lit in orange. Interface for an adapter cable used when setting and storing parameters from a PC. Each time you press the key, it switches to the. Used to switch or register a parameter. Pressing the key for more than 3 second allows you to switch.

Used to switch between displays. Pressing this key while any operating display is shown lets. Pressing this key while any display other. One to four presses maximum. Used to change numerical values. On setting displays for various parameters, you can change target.

These keys also switch between menu displays when a main menu or. Then, set PV input type, control output type and others. In steps 2 and later, illustrations of the LCD are cited to explain the procedure. The controller re-starts which is normal. Then, set PV input type.

Bring the operating display into view display appears at power-on. The following operating procedure describes an example of setting a K-type thermocouple PV input type IN1 : Set according to a sensor. PV input type IN1 : Set according to an input signal. After a change has been made to any of these data items, be sure to verify the registered operating parameter setpoints to ensure that they are correct.

If any data item has been changed to its default, set it to a required value. The PV display in the figure below shows the error code for input burnout if PV input wiring is not yet complete. The error code disappears when you wire the PV input terminals correctly.

Press the or key to display the required setpoint. The figure below shows an example of setting the PV input type to a K-type thermocouple The figure below shows an example of setting the minimum value of the PV input range to 0. Press the key for more than 3 seconds. This returns you to the display shown at power-on figure below.

Note 2: The accuracy is 0. Note 3: Not used in cascade secondary-loop control. This resistor is optional. The following operating procedure describes an example of changing time proportional PID relay output 0: factory-shipped value to current output 2.
