Output stops when the status is STOP. Why don't PID items appear? What protocol is used when communicating with the Mitsubishi Electric's sequencer? Do you offer programs for communication using calculator link units or serial communication units? What are direct and reverse action? Generally, reverse action means heating control and direct action means cooling control. What is the write limit of , times? Auto-tuning parameters AT don't appear.

What registers are accessible in UT link's Auto mode? It depends on the model. The following lists the readable registers by model. 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.

Is there a function for determining the PID? Is there anything I need to be careful of in terms of wiring? 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. Are current control output and transmission output isolated? Can you give me details on the "Super" function? This is an overshoot suppression function that uses fuzzy logic. It constantly monitors deviation, and if it detects the possibility of an overshoot, it automatically changes the set point to a somewhat lower temp value sub set point SSP.

When y Can you give me details on ladder communication? Affected products: UT series, Green series ns-faq-greenterm. What registers are accessible in UT link's Auto mode?

When y Can you give me details on ladder communication? Affected products: UT series, Green series ns-faq-greenterm. Ladder communication is a protocol for communication with PLCs. Can you give me details on PC link communication? Also, you can easily connect with PLCs Is control output available on a failure?

Can you give me details on Modbus communication? This is a protocol for communication with general purpose PCs and graphic panels. 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 There is no current input range. Use a resistor to input current as voltage. The controller operates in such a manner that the setpoint changes to the target setpoint over the segment time set for segment 1, irrespective of what the PV value is.

Letting the controller start from the current PV and run according to ramp settings defined for segment 1 of the created program Starting Point of Operation Controller Behavior Begins to run from point C1 ignores the time setting defined for segment 1. Begins to run from point C1 ignores the time setting defined for segment 1. You can also append program pattern 2 to program pattern 1. Precautions when Linking Programs There may be a case that a difference exists between the target setpoint defined for the final segment of a program pattern to be run first and the starting target setpoint of a pro Page Program Pattern Setup Charts Fill in the fields with bold-face borders in the order of steps 1 to 10, as shown below.

Then, input these setup data items to the UP Page 52 Blank Page Make sure the controller is in Run state PRG before carrying out auto-tuning. PID constants are obtained by using the current program setpoint value at the start of auto- tuning. This starts auto-tuning. In this case, PID contains the value existing before auto-tuning.

Bring the operating display into view appears at power-on. SP display: Displays the PV input value. This procedure also applies to program pattern 2. NOTE If a contact input is on hold mode is set when the hold mode is enabled and disabled with the input, the mode cannot be cancelled by key operation. Blinks during change.

Displays PV. Page 62 Blank Page If a problem appears complicated, contact our sales representative. Is the instrument defective?

Is key NOTE Do not use alcohol, benzine, or any other solvents. Do not touch the terminals on the rear panel when power is being supplied to the controller. Doing so may result in electric shock. Before attaching the terminal cover, turn off the source circuit breaker and use a tester to CAUTION check that the power cable is not conducting any electricity.

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. When should I use sensor power supplies affected models: certain Green series instruments? 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. I can't switch the SP. Check whether you are trying to switch it via communication, or whether it is the zone PID. Are there independent PIDs for heating and cooling? 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? Can you give me details on the "Super2" function? Affected products:Green series ns-faq-greenterm.

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.

What PID should be used for remote input? Output stops when the status is STOP. Why don't PID items appear? What protocol is used when communicating with the Mitsubishi Electric's sequencer? Do you offer programs for communication using calculator link units or serial communication units?

What are direct and reverse action? Generally, reverse action means heating control and direct action means cooling control. What is the write limit of , times? Auto-tuning parameters AT don't appear. What registers are accessible in UT link's Auto mode?
