5. no direct radiant heat is present,

6. no magnetic disturbances are caused,

7. no wind blows against the terminal board (reference junction compensation element),

8. no water is splashed,

9. no flammable materials are around,

Never place the controller directly on flammable items or equipment.

If the controller has to be installed close to flammable items or equipment, be sure to provide shielding panels all around the controller, at least 150 mm away from every side; the panels should be made of either 1.43 mm-thick metal-plated steel plates or 1.6 mmthick uncoated steel plates.

● Installation Position

Install the controller at an angle within 30 from horizontal with the front panel facing upward. Do not install it facing downward. The position of right and left sides should be horizontal.

■ 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.

Used to switch between the AUTO and MAN modes. Each time you press the key, it switches to the AUTO or MAN mode alternately.

Used to switch or register a parameter. Pressing the key for more than 3 second allows you to switch between the operating display and the main menu for operating parameter setting display alternately.

Used to switch between displays. Pressing this key while any operating display is shown lets you switch to another prearranged operating display. Pressing this key while any display other than an operating display is shown lets you go back one display. (One to four presses (maximum) of this key lets you return to the current operating display, though the number of presses depends on the operating status.)

Used to change numerical values. On setting displays for various parameters, you can change target setpoints, parameters, and output values (in manual operation). Pressing the key decreases a numerical value, while pressing the key causes it to increase. You can hold down a key to gradually increase the speed of change. These keys also switch between menu displays when a main menu or submenu of parameter setting display is shown.

2.9 Description of Multiple Setpoints and PID

The UT750 has a maximum of eight target setpoints, and has PID for each of these setpoints. The following shows the correspondence between the target setpoint numbers (SPNO), target setpoints (SP), and PID parameters.

For example, if you have set “2” to the target setpoint number (SPNO), the control parameters available are target setpoint (2.SP), proportional band (heating-side proportional band) (2.P), integral time (heating-side integral time) (2.I), derivative time (heating-side derivative time) (2.D), cooling-side proportional band (2.Pc), cooling-side integral time (2.Ic), and cooling-side derivative time (2.Dc).

To use multiple target setpoints, see the table below to check the corresponding parameters.

3.4 Performing/Canceling Auto-tuning of Secondary-loop

Auto-tuning should be carried out after setting a target setpoint (SP) of the secondary-loop. Make sure the controller is in automatic operation mode (AUTO) and in running state (RUN) before carrying out auto-tuning. See “3.11 Switching between Cascade (CAS), AUTO and MAN,” to change to AUTO and “3.10 Switching between Run and Stop,” to change to RUN.

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 affect-

ing product quality

■ 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).

4-4

• The UT750 controllers have a universal input. The type of PV input can be set/changed using the parameter “IN1”. 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 UT750 controllers have a universal output. The type of control output can be set/changed using the parameter “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 MAN1 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 “MOD”. In cases where fixed-point control is selected as the PID control mode (MOD = 1), tracking based on the I-term 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.

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.

Pull out the relay to be replaced.

The control output relays are easy to remove and mount, since they are connected via a socket onto the print boards.

Insert the new relay in the socket. Use the following relay.

Manufacturer OMRON

Model G6B-2114P-FD-US-P6B

Power supply 12 V DC

Insert the internal unit into the housing.

Apply power to the controller and confirm that the initial operating display is shown. If the operating display is not shown properly, turn off the controller and pull out the internal unit. Then, insert it into the housing again.

4-10

This completes replacement of the control output relay.

5.2 Lists of Parameters

This section describes the functions of parameters briefly. In addition, each parameter table has a “User Setting” column, where you can record your setpoints when setting them in the controller.

* Parameters relating to PV or setpoints should all be set in real numbers.

For example, use temperature values to define target setpoints and alarm setpoints for temperature input.

* The “User Setting” column in the table is provided for the customer to record setpoints.

* Numbers in ( ) are the parameter setpoints that apply when the communication func-

tion is used. ex. AUTO (0), MAN (1), CAS (2).

Reference deviation

Used to select a group of PID parameters according to a deviation from

OFF (0) the given target setpoint. The controller uses the parameters of the number selected in PID group number (GRP) if the PV input falls outside the given deviation range. The following example shows a case when only the reference deviation is set without setting any reference point. The selected set of PID parameters is as follows. Since region 1 is within the deviation range, the controller uses the 1st group of PID parameters. Since region 2 is outside the deviation range, the controller uses the parameters of the number selected in PID group number (GRP).

Sets reference points at which switching is carried out between groups of PID constants according to the given temperature zone. You can set a maximum of six reference points and therefore a maximum of seven temperature zones. To enable this parameter, set the Zone PID Selection (ZON) parameter to “1”.

The example below sets reference points 1 and 2 to provide 3 zones to switch PID constants automatically. Maximum 7 zones selectable.

0.0 to10.0% of secondary PV input range span Allows hysteresis to be set for switching at a reference point.

Used to select a group of PID parameters according to a deviation from the given target setpoint. The controller uses the parameters of the number selected in PID group number (GRP) if the PV input falls outside the given deviation range. The following example shows a case when only the reference deviation is set without setting any reference point. The selected set of PID parameters is as follows. Since region 1 is within the deviation range, the controller uses the 1st group of PID parameters. Since region 2 is outside the deviation range, the controller uses the parameters of the number selected in PID group number (GRP).
