■ How to Install

Turn off the power to the controller before installing it on the panel because there is a possibility of electric shock.

CAUTION

After opening the mounting hole on the panel, follow the procedures below to install the controller:

1. Insert the controller into the opening from the front of the panel so that the terminal board on the rear is at the far side.

2. Set the brackets in place on the top and bottom of the controller as shown in the figure below, then tighten the screws of the brackets. Take care not to overtighten them.

1.3 How to Connect Wires

1) Before carrying out wiring, turn off the power to the controller and check that the cables to be connected are not alive with a tester or the like because there is a possibility of electric shock.

CAUTION

2) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.

NOTE

1) Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC2205-00U from TDK) on the secondary side. As a countermeasures against noise, do not place the primary and secondary power cables close to each other.

2) For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires. The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.

1-5

3) Control output relays may be replaced. However, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load.

4) The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load.

3. Programming

This chapter explains how to create programs by citing specific examples. Create user programs by referring to the given programming examples. Use the parameter map included in “3.5 Program Parameter Map,” in order to further familiarize yourself with the required operations.

Be sure to carry out the settings instructed in “2. Initial Settings” before beginning any of the tasks discussed in this chapter.

3.1 Overview of Program Patterns

■ Programming Overview

The programming example given here demonstrates how to do the tasks outlined below.

1. Program the controller to start program operation of Loop1 at 25⬚C and raise the temperature up to 80⬚C in 20 minutes. And program the controller to start program operation of Loop2 at 0⬚C and raise the temperature up to 60⬚C in 20 minutes.

2. When the temperature of Loop1 reaches 80⬚C, keep it at this level for 80 minutes. And when the temperature of Loop2 reaches 60⬚C, keep it at this level for 80 minutes.

3-1

3. Finally, Loop1 and Loop2 lower the temperature to 0⬚C in 10 minutes.

Event output

• Set a deviation of 5⬚C on both the positive and negative sides of a program setpoint to allow the controller to output of Loop1 an event signal if the temperature goes beyond the deviation range.

• Let the controller output of Loop1 an event signal when the temperature stabilizes to 80⬚C.

3.3 Creating Program Patterns

The following operating procedure describes an example of creating the program discussed in “3.1 Overview of Program Patterns.”

NOTE

Before creating the program, reverify the Maximum Value of PV Input Range of Loop1 and Loop2 (RH1, RH2), Minimum Value of PV Input Range of Loop1 and Loop2 (RL1, RL2), Program Time Unit (TMU), and Segment Setting Method (SEG.T) parameters.

If the setting of the setup parameter “SEG.T” is changed, the program patterns created and stored so far will be all cleared (initialized)!! Be careful.

Is common as program pattern segment of Loop1 and Loop2

The programming example given in this section includes the following steps.

• Step 5 selects the program pattern number (PTN).

• Steps 7 to 12 configure the parameter Starting Target Setpoint of Loop1 (SSP1) (so

that the program starts from 25⬚C), and the parameter starting Target Setpoint of Loop2 (SSP2) (so that the program starts from 0⬚C).

3-4

• Steps 14 to 19 configure the Final Target Setpoint (TSP1) parameter for segment 1.

• Steps 20 to 22 configure the Segment Time (TIME) parameter of Loop1 and Loop2 for

segment 1.

• Steps 23 to 31 configure the PV Event parameters (EV1, TY1 and PE1).

• Step 34 configures the Final Target Setpoint of Loop1 (TSP1) parameter for segment

2 (not changed in this example).

• Step 35 configures the Final Target Setpoint of Loop2 (TSP2) parameter for segment 2 (not changed in this example).

• Steps 36 to 38 configure the Segment Time (TIME) parameter for segment 2.

• Steps 39 to 47 configure the Time Event parameters (EV1, ON1 and OFF1).

• Steps 50 to 55 configure the Final Target Setpoint of Loop1 and Loop2 (TSP1, TSP2)

parameter for segment 3.

• Steps 56 to 58 configure the Segment Time (TIME) parameter for segment 3.

3.8 Explanation of Program Functions

■ Programming

You can create programs using either method 1 or 2 described below.

The controller is factory-set to “method 1.” To create programs using method 2, change the setpoint of the SEG.T (Segment Setting Method) setup parameter to “1.”

Before you begin programming, determine whether your programs are created using the time unit of “hour and minute” or “minute and second.” The controller is factory-set to the “hour and minute” time unit. To create programs using the “minute and second” time unit, change the setpoint of the TMU (Program Time Unit) setup parameter to “mm:ss.”

Setpoint of SEG.T (Segment Setting Method) Setup Parameter Time setting (method 1) 0 (factory-set default) Ramp setting (method 2)

Choose the desired method and unit from the two programming methods and time unit options discussed above. Then, create programs according to the chosen options.

1. Creating programs by setting final target setpoint and time unit

3-26

As shown in the figure below, this method creates programs by setting a segment time and a final target setpoint on a segment-by-segment basis.

2. Creating programs by setting final target setpoint and ramp

As shown in the figure below, this method creates programs by setting a final target setpoint and a ramp grade on a segment-by-segment basis.

Define the ramp grade as the amount of change in the setpoint per hour or per minute.

Time

To change the temperature linearly over a minute, set the TMU parameter to “mm:ss” (minute and second) before you begin programming.

When programming the controller, set the Segment Time (TIME) parameter for segment 1 to 5⬚C.

This allows the controller to raise the setpoint in increments of 5⬚C per minute during the interval of segment 1.

■ Controller Behavior at the Start of Program Operation

You can determine how the controller should behave at the start of program operation.

1. Letting the controller run from a starting target setpoint

A starting target setpoint refers to a setpoint from which program operation begins. The controller operates in such a manner that the setpoint changes to the final target setpoint over the segment time set for segment 1, irrespective of what the PV value is.

Set the STC (Start Code) program parameter to “0”.

2. Letting the controller start from the current setpoint and run according to time settings defined for segment 1

This method is not available if the SEG.T (Segment Setting Method) parameter is set to “ramp setting.”

Starting Point of Operation Controller Behavior a Begins to run from point a according to the time setting defined for segment 1. b Begins to run from point b according to the time setting defined for segment 1. c Begins to run from point c according to the time setting defined for segment 1. d Begins to run from point d according to the time setting defined for segment 1. e Begins to run from point e according to the time setting defined for segment 1.

■ PID Switching (Zone PID)

The UP750 offers two methods of PID switching. One of the methods is to automatically switch between groups of PID constants according to the temperature zone. The other method is to automatically switch between groups of PID constants on a segment-bysegment basis. This paragraph explains the method of switching between groups of PID constants according to the temperature zone. You can set a maximum of seven temperature zones. When shipped from the factory, the UP750 is configured so that it operates in zone 1 only and uses only one group of PID constants.

● When One Group of PID Constants is Used (factory-set default)

As shown in the figure below, the controller uses one group of PID constants over the range from the minimum value to the maximum value of the PV input range.

● Selection of PID Constants when the Control Range is Split into Three Zones

As shown in the figure below, three zones are set for the controller to automatically switch from one group of PID constants to another. Two zones can also be set for the controller to switch between two groups of PID constants.

[1] The controller uses the 1st group of PID constants if the PV input value is within the

zone set off by the minimum value of the PV input range and reference point 1.

[2] The controller uses the 2nd group of PID constants if the PV input value is within the

zone set off by reference point 1 and reference point 2.

[3] The controller uses the 3rd group of PID constants if the PV input value is within the

zone set off by reference point 2 and the maximum value of the PV input range.

• Splitting the control range into two zones

- To split the control range into two zones, define reference point 1 (i.e., the 1.RP1 setup parameter).

- Define the 1st and 2nd groups of PID constants (i.e., the 1.P, 1.I and 1.D operating parameters for the 1st group and the 2.P, 2.I and 2.D operating parameters for the 2nd group).

• Splitting the control range into three zones

- To split the control range into three zones, define reference points 1 and 2 (i.e., the 1.RP1 and 2.RP1 setup parameters).

- Define the 1st, 2nd and 3rd groups of PID constants (i.e., the 1.P, 1.I and 1.D operating parameters for the 1st group, the 2.P, 2.I and 2.D operating parameters for the 2nd group and the 3.P, 3.I and 3.D operating parameters for the 3rd group).

● Selecting PID Constants According to the Deviation

PID constants can be selected according to the deviation in two ways. One method is to select a group of PID constants only by a deviation from a program setpoint. The other method is to use a reference point, as discussed earlier, as well as a deviation from a program setpoint, to switch between groups of PID constants.

[Method 1]

As shown in the figure below, the controller selects the PID constants of the group number set in PID group number (GRP) if the PV input value goes beyond the given deviation from the program setpoint.

[1] The controller uses the 1st group of PID constants.

[2] The controller uses the PID constants of the group number set in PID group number

(GRP).

[Method 2]

As shown in the figure below, the controller selects an appropriate group of PID constants for each zone and, if the PV input value goes beyond the given deviation from the program setpoint, selects the PID constants of the group number set in PID group number (GRP).

[1] The controller uses the 1st group of PID constants if the PV input value is both within

the zone set off by the minimum value of the PV input range and reference point 1 and within the given reference deviation bandwidth.

[2] The controller uses the 2nd group of PID constants if the PV input value is both within

the zone set off by reference points 1 and the maximum value of the PV input range, and within the given reference deviation bandwidth.

[3] The controller uses the PID constants of the group number set in PID group number

(GRP).

■ Retaining the End-of-Program State (Hold-mode End)

This function keeps the controller in the same state as when program operation was completed.

When in hold operation, the controller retains its states of control output and event output. To cancel hold operation, use either key operation or external contact input. When the hold operation is cancelled, the control output is set to 0% or OFF, and the event output is set to OFF.

To retain the end-of-program state, set the Junction Code program parameter of the segment in question to “1.”

■ Suspending the Progress of a Program (Wait Function)

When a running program moves from one segment to another, the wait function places the program in a wait (stand-by) state, by using a wait zone and a wait time, until any deviation is cancelled.

A wait zone is a deviation bandwidth from which the degree of PV input tracking is judged.

A wait time is the length of time that elapses until the PV input enters the wait zone. The program progresses if the PV input fails to re-enter the wait zone within the wait time.

When the program is in wait state, the time setpoints of Segment Time and Time Event parameters temporarily cease to be passed. At this point, the output based on the Time Event parameter is retained.

4.2 Performing/Canceling Auto-tuning of Loop1

Perform auto-tuning when you have finished creating program patterns. Make sure the controller is in program (RUN) mode and in automatic (AUTO) mode before carrying out auto-tuning. See “4.7 Switching between RUN and RESET Modes,” to change to RUN or “4.8 Switching between AUTO and MAN of Loop1,” to change to AUTO.

PID constants are obtained by using the current program setpoint value at the start of autotuning.

NOTE

When on-off control is being used, auto-tuning cannot be carried out. Moreover, do not perform auto-tuning when controlling any of the following processes.

• Control processes with quick response such as flow control or pressure control

• Processes where even temporary output on/off results in inconvenience

• Processes where a large output change at control element results in inconvenience

• Processes where variations in PV may exceed an allowable range, adversely affecting product quality

Remedy

■ Remedies if Power Failure Occurs during Operations

The operation status and remedies after a power failure differ with the length of power failure time:

● Instantaneous Power Failure of 20 ms or less

A power failure is not detected. Normal operation continues.

● Power Failure of about 2 seconds or less

The following show effects caused in “settings” and “operation status.”

Alarm action Continues. Alarm with standby function will enter standby status.

Settig parameter Set contents of each parameter are retained.

Auto-tuning Cancelled.

Control action Action before power failure continues.

■ Troubleshooting when the Controller Fails to Operate Correctly

If your control tasks are not successful, check the preset parameters and controller wiring before concluding the controller to be defective. The following show some examples of troubleshooting you should refer to in order to avoid the possibility of other problems.

● The Controller does not Show the Correct Process Variable (PV).

5-4

• The UP750 controllers have a universal input. The type of PV input can be set/changed using the parameter “IN1,” “IN2.” At this point, the controller must be wired correctly according to the selected type of PV input. Check the wiring first if the controller fails to show the correct PV value. To do this, refer to “2. Initial Settings.” With the parameters “RH1”, “RL1”, “SDP1”, “SH1” and “SL1”, it is possible to scale the input signal and change its number of decimal places. Also check that these parameters are configured correctly.

● The Controller does not Provide any Control Output or the Control Output does not Change at all.

• The UP750 controllers have a universal output. The type of control output can be set/changed using the parameter “OT1,” “OT2.” At this point, the controller must be wired correctly according to the selected type of control output. Check the wiring first if the controller provides no control output. To do this, refer to “1.5 Terminal Wiring Diagrams.” With the parameters “OH” and “OL”, it is possible to set/change the high and low limits of control output. The control output may not change at all, however, because of restrictions on these parameters. Also check the restrictions on these parameters.

• The control output can only be changed when the controller is in the MAN mode. If the MAN lamp is off (i.e., the controller is in the AUTO mode), you cannot change the control output using key operation.

● The Control Output does not Change soon after the Target Setpoint SP has been Changed.

• If this happens, check the setpoint of the parameter “MOD1”. In cases where fixedpoint control is selected as the PID control mode (MOD1 = 1), tracking based on the Iterm works to prevent the control output from changing suddenly even if the target setpoint SP is varied. The control output therefore may appear to be working incorrectly at first; however it gradually adapts itself to the new target setpoint. Be especially careful when the controller is in the fixed-point control mode; the control output may fail to change and therefore result in a loss of control if you change the target setpoint SP too frequently.

■ Attaching Terminal Cover

The procedure for attaching the terminal cover is as follows.

Do not touch the terminals on the rear panel when power is being supplied to the controller. Doing so may result in electric shock.

5-6

CAUTION

Before attaching the terminal cover, turn off the source circuit breaker and use a tester to check that the power cable is not conducting any electricity.

Before attaching the terminal cover, fold it once or twice so that the side which has the “Handle With Care” symbol ( ), is on the outside.

Fold over.

NOTE

Do not fold the terminal cover the wrong way, doing so not only reduces the cover’s strength but may also cause the hinge to crack, thereby disabling attachment.

With the cover properly folded, fit its top and bottom holes to the protrusions of the

mounting brackets.

Fit the hole of the terminal cover to the protrusion on the mounting bracket.
