Chapter 1 US1000 Digital Indicating Controller

1. US1000 Digital Indicating Controller

The US1000 digital indicating controller is designed with sophisticated, yet user-friendly control functions. The displays and operation keys on the front panel provide for smooth and secure operation.

● Simplified setup

The typical setup of the US1000’s basic control function and the I/O terminal assignment are registered as the “controller mode (US mode).” Users can easily setup the controller by selecting this controller mode.

● A wealth of displays and operating functions

The US1000 controller has two easy-to-read digital displays and three bar graphs as analog displays. The operation mode is switched and MV output modified using the dedicated keys.

IM 5D1A01-01E 2-3

3. Wiring

This chapter describes the wiring procedure and terminal assignment of the US1000 controller. The optimum sets of signals are automatically assigned to the terminals according to the model and suffix code of your controller, the controller mode (US mode), and the type of control computation output.

See Also

• Section 4.3, “Selecting the Controller Mode (US Mode),” for information on the controller modes (US modes).

• Section 4.5, “Selecting the Control Computation and Output Types,” for information on the control computations.

CAUTION

• Before you start wiring, turn off the power supply source and use a tester to check that the controller and cables are not receiving any power.

•Never touch a terminal when power is being supplied; you will get an electrical shock if you do.

• Be careful to connect the correct polarities. Connecting the wrong polarity may result in a serious accident.

• If the controller and any external equipment connected to it are to be used in a hazardous area (as non-incendive equipment), the external equipment and the wiring conditions must satisfy the requirements specified in Appendix 6, "Conditions of Use in Hazardous Areas." If these conditions are not satisfied, the controller itself may be the source of a fire.

Chapter 3 Wiring

3.1 Procedure for Wiring

This section describes the cables used for wiring, the terminal assignment, and the wiring for power supply. Once wiring is complete, a terminal cover should be attached as outlined in subsection 3.1.6.

3.1.1 Cables and Terminals

For the thermocouple input, use shielded compensating lead wires. The resistance temperature detector (RTD) input requires shielded cables with low resistance and no resistance differential between the three wires. The specifications for the cables and terminals used in the wiring are as follows.

• Power supply wiring: 600 V vinyl insulation electric wire, JIS C 3307, 0.9 to 2.0 mm

• Thermocouple wiring: Shielded compensating lead wire, JIS C 1610

• RTD input wiring: Shielded 3-core wire, UL2482 (product of Hitachi Cable)

•Terminal: Crimp-on terminals with insulation sleeves and of a size suitable for

M3.5 screws (see the figure below).

• Terminal tightening torque: 0.8 N•m (8 kgf•cm) or less

3.1.3 Preventing Noise

NOTE

• To prevent electromagnetic wave radiation, use shielded wires for the wiring for the thermocouple input, RTD input, DC input, current output or voltage pulse output. The shiled must be grounded.

• Bundle the connected cables together tightly.

Consider the following noise-prevention points when performing wiring.

• Keep the input circuit wires as far away as possible from the power lines of other equipment.

• The use of shielded wires is effective against noises from electrostatic induction. Connect shielding to the grounding terminal if necessary. Be sure to ground each wire independently.

• Twining input wires at short regular intervals can be quite effective at eliminating the noise from electromagnetic induction.

• Keep the power supply wiring more than 10 cm away from the signal wiring.

3.1.5 Wiring for Power Supply and Transmitter’s Loop Power Supply

Perform wiring for the power supply and the transmitter’s loop power supply as instructed below.

■ Wiring for Power Supply

• Use a single-phase power source.

•Use wires or cables with a minimum performance equivalent to that of 600 V vinyl insulation electric wires (JIS C 3307).

• If the source has a lot of noise, use an insulation transformer and line filter as shown in the figure below. The recommended line filter is TDK’s ZAC2205-00U.

• When this noise-prevention measure is taken, keep the primary and secondary power cables well apart.

• To ensure safety, install a circuit breaker switch or an equivalent safety device and be sure that usage instructions for the device are clearly displayed.

3.1.6 Attaching the Terminal Cover

When you complete the wiring, attach the terminal cover as follows to prevent electrical shocks.

1. Fit the holes in the upper part of the terminal cover over the protrusions in the upper part of the housing.

2. Insert the screw at the bottom of the terminal cover into the screw hole in the rear of the controller and tighten it.

3.2 Signals Assigned to Terminals

The US1000 controller has different signals assigned to terminals depending on the controller’s model and suffix code, the controller mode (US mode), and the type of the control computation. Refer to the relevant subsection according to your controller’s model and suffix code.

Model US1000-00: Subsection 3.2.1 Model US1000-11: Subsection 3.2.2 Model US1000-21: Subsection 3.2.3 In each subsection, tables are given for each controller mode (US mode) and control computation type.

Refer to the table that applies to your controller’s settings.

See Also

• Section 4.3, “Selecting Controller Mode (US Mode),” for information on the controller modes (US modes).

•Section 4.5, “Selecting Control Computation and Output Types,” for information on the control computations.

● Contact Input Function

The functions assigned to the contact inputs are as follow.

• RUN/STOP switchover: The controller is in STOP status when the contact is on, and in the

RUN status when the contact is off.

•CAS/AUTO/MAN mode selection:

When the contact is turned from off to on, the operation mode changes to the corresponding mode.

•Tracking switching: Tracking signal of AIN2 or AIN3 is effective when the contact is on.

• OPEN/CLOSE switchover: Cascade control is disabled (OPEN) when the contact is on; cascade

control is enabled (CLOSE) when contact is off.

• ‘PV-hold and MAN mode’ or ‘AUTO mode’:

The controller holds PV in MAN mode when the contact is on, and is in the AUTO mode when contact is off.

3-6

● Alarm Output 1 to 4

The initial alarm types of the alarm output 1 to 4 are: Alarm output 1: PV high limit Alarm output 2: PV low limit Alarm output 3: PV high limit (secondary) Alarm output 4: PV low limit (secondary) To change the alarm type assignments, refer to section 4.7, “Defining Alarm Outputs.”

Chapter 4 Setting the Basic Functions

4. Setting the Basic Functions

This chapter describes the setting procedure and the meanings of the parameters used to select and adjust the US1000 controller functions.

The parameters of the US1000 controller are largely divided into two types: “operation parameters” and “setup parameters.”

• Operation parameters are the parameters that are changed relatively often during operation.

• Setup parameters are the parameters that determine the controller functions and are rarely changed once they have been set.

Some parameters must be set before operation (such as the controller mode (US mode) and the input type), while others can be set as necessary according to the user’s needs. This chapter describes the setting procedure for parameters that must be set and those that are used often. Refer to the parameter lists in Appendixes 3 and 4, and the parameter maps in Appendix 5 to set the other parameters.

IM 5D1A01-01E 4-1

4.1 Example of Parameter Display

To set an operation parameter or setup parameter, first call up the main menu to which the parameter belongs. Then, from the main menu, call up the submenu which contains the parameter, and then the target parameter from that submenu.

Appendix 5 shows the locations of all of the main menus, submenus, and parameters to help you call up parameters.

● Examples of parameter display

When a main menu is displayed, the top bar flashes slowly.

This decimal point flashes on loop-2 menus.

When a submenu is displayed, the middle bar flashes slowly.

This decimal point flashes on loop-2 submenus.

When a parameter is displayed, the bottom bar flashes slowly.

This decimal point flashes on loop-2 parameter displays.

Press the MAN mode key for 0.5 seconds.

4.3 Selecting the Controller Mode (US Mode)

The controller mode (US mode) determines the basic action of the controller. The US1000 controller has 14 selectable controller modes.

NOTE

•Since changing the controller mode resets the internal functions of the controller and initializes the related parameters accordingly, be sure to set the controller mode before setting other parameters.

• Some controller modes cannot be selected depending on the model and suffix codes of the US1000 controller. US1000-00: Modes that cannot be selected include dual-loop control, temperature and humidity control, cascade control with two universal inputs, loop control with PV switching or PV autoselector and two universal inputs, and custom computation control. US1000-21: Modes that cannot be selected include cascade primary-loop control, dual-loop control, and temperature and humidity control.

4.4 Selecting the PV Input Type

The US1000 controller supports universal inputs and can receive the signals from a thermocouple and RTD, and from standard signals and DC voltage signals, as PV inputs. Up to 3 inputs are available depending on the model and suffix code, and you can set the input type and range for each input.

■ Analog Input Terminals of the US1000 Controller

The US1000 controller has a maximum of 3 analog input terminals. The AIN1, AIN2, and AIN3 terminals correspond to analog inputs 1, 2, and 3, respectively. In this section, the procedure to set analog input 1 is described. If you are also using analog input 2 and/or 3, set them in the same manner.

•AIN1 terminal: Universal analog input terminal used for a PV input.

•AIN2 terminal: Universal analog input terminal. This terminal is not provided on the US1000-

00 model (which only has AIN1 and AIN3 terminals).

•AIN3 terminal: Analog input terminal for voltage input and used for cascade input etc..

TIP

• Signals assigned to the analog input terminals

Setting the controller mode (US mode) automatically sets the input signals used in that controller mode, such as the PV input, cascade input, feedforward input, tracking input, etc., to the AIN1, AIN2, and AIN3 terminals.

See Also

Section 3.2, “Signals Assigned to Terminals,” for the signal assignment of the analog input terminals.

In this section, the procedure to set the type-J thermocouple and a measurement range of 0 to 500°C for the AIN1 signal is described as an example.

4.5 Selecting the Control Computation and Output Types

You can select the type of control computation for each control loop. Normally, there is a single control loop. In the controller mode (US mode) for “dual-loop control” and

“temperature and humidity control”, however, the US1000 controller has two control loops and a control computation type must be selected for each loop.

The types of control computation are listed in the table below. Each control computation has a specific output type. The control computation for the US1000-21 model is fixed at position proportional PID and cannot be changed.

NOTE

Some control computation types cannot be selected depending on the US1000 model and suffix code. US1000-00: Only “time proportional PID computation with voltage pulse output” and “continuous

PID computation” can be selected. US1000-11: All types except for “position proportional PID computation” can be selected. US1000-21: Only “position proportional PID computation” can be selected. It cannot be changed.

4.7 Defining the Alarm Outputs (as necessary)

The alarm outputs are pre-assigned to the US1000 controller’s contact output terminals. For example, the US1000-00 (basic type) set up for single-loop control (US mode = 1) assigns alarm output 1, alarm output 2 and alarm output 3 to DO1 (terminal nos. 9 and 12), DO2 (terminal nos. 10 and 12) and DO3 (terminal nos. 11 and 12), respectively. Refer to section 3.2 for the assignments of the other controller modes.

Any one of the alarms listed in the table below can be assigned to each alarm output.

(15) Password setting for parameter change operation

You can set a password to prevent accidental or careless changes to setup parameter settings. The password is verified in the transmission from the operation parameter display to the setup parameter display.

The password setting range is from 0 (no password) to 30000.

NOTE

• Be sure to memorize the password. Once a password has been set, you cannot transmit to the setup parameter setting display without entering the correct password. To cancel a lost password, the controller must be sent back to a Yokogawa service center for repair at your cost.

• In the repair service, all parameters are initialized to the factory-set defaults. Thus, it is recommended to keep records of the user-set values for all of the parameters.

6.1 Switching the Operation Mode

■ US1000 Operation Modes

The US1000 can operate under one of the following operation modes: MAN mode: In this mode, MV can be manipulated manually using the MV operation keys. AUTO mode: This mode performs automatic control so as to maintain the SV. SV can be changed

using the SV setting keys on the front panel.

CAS mode: This mode performs automatic control, regarding the cascade input from either an

analog input signal or from RS-485 communication as the target setpoint.

■ Switching the Operation Mode

To switch the operation mode, press and hold either the (MAN mode) key for 0.5 sec. to switch between modes, as follows:

CAS mode

AUTO mode

(CAS mode), (AUTO mode) or

MAN mode

NOTE

• The key is locked (disabled) for the default setting to avoid undesirable mode change. So,

release the C mode key lock first, before you can enter the CAS mode. (See section 4.9 (16) for the information about key lock.)

• You cannot switch directly from the MAN mode to CAS mode. You must switch to the AUTO mode first, before you can enter the CAS mode.

• Even if the cascade-input signal is -5.0% or less or 105.0% or more, the operation mode can be switched to the CAS mode.

6.11 Auto-tuning

Auto-tuning is a US1000 function that measures the process characteristics and automatically sets the optimum PID parameters during PID control. Auto-tuning is activated by the parameter setting.

The auto-tuning uses a “Stepping Response Method.” When auto-tuning is activated, MV output turns on and off temporarily in a step-like manner. An appropriate PID is calculated and set from the response data.

WARNING

Do not use the auto-tuning function for the following processes.

• Fast-response processes such as flowrate and pressure.

• Processes in which a severe change in output, even if temporary, is undesirable.

• Processes in which any severe stress on the operating terminal is undesirable.

• Processes in which product quality can be adversely affected if PV fluctuates beyond its allowable range.

CAUTION

• Auto-tuning is only available when the operation mode is set to AUTO.

•Before auto-tuning can be performed, the target setpoints and other parameters must be set up.

• Auto-tuning is not available for ON/OFF computation control.

• Auto-tuning is disabled when the US1000 is inactive.

TIP

• To interrupt auto-tuning, set the AT parameter to off. Auto-tuning stops and the PID constant stays unchanged at the same value as before auto-tuning was started.

•Even if SV is changed during auto-tuning, auto-tuning is still based on the SV set when started. After completing auto-tuning, control is conducted according to the modified SV.

• Changing a PID constant during auto-tuning is not made effective, since the constant is reset when auto-tuning ends. The parameters are not reset when auto-tuning is terminated forcibly however, thus making the changed values effective.

• If an input burnout or A/D data conversion error occurs during auto-tuning, auto-tuning stops and outputs the preset MV value.

• If auto-tuning is run for more than 24 hours, it is terminated upon the auto-tuning timeout time and

6.12 Manual Tuning

To using the US1000 with an unknown process, clarify the conditions for MAN mode operation as this will help you determine the proportional band, integral time and derivative time for the AUTO mode. For example, if PV varies considerably by changing the US1000 output slightly, the proportional band shall be set wide. Conversely, if PV varies only slightly with changes in output, then the proportional band shall be set narrow. In addition, if only a short delay time is allowed for changes made to the controller’s MV, then the integral time and derivative time must be set short. For processes which have longer recovery time, the integral time and derivative time must be set long.

■ Tuning with Geglar/Nichols’s Limiting Sensitivity

There are a number of adjustments that can be made to determine the proportional band, integral time and derivative time. The method described here yields a response characteristic of 25% damping.

1. Set the operation mode to MAN and manipulate PV manually so that it matches SV. Set the integral time to 9999 sec., the proportional band to a large value and the derivative time to OFF.

2. Set the control operation mode to AUTO.

3. Decrease the proportional band from its large value (e.g., 100% → 50% → 20%). In this case, allow enough time to pass so that the control conditions can be monitored at every step. Continue this operation until the control loop starts continuous oscillation (cycling).

TIP

Cycling occurs when the proportional band is set narrower than the band allowed by the maximum value of the process, and is evident by the regular oscillation of PV around SV at the center.

4. Locate the point at which cycling starts. Measure the proportional band value (PBu) and cycling frequency (Pu).

5. The optimum PID parameter setpoints are yielded as follows:

Proportional band (P): 1.7 PBu Integral time (I) : 0.5 Pu Derivative time (D) : 0.125 Pu

6.14 Power Failure during Operation

The US1000’s operation is not affected by power failures of less than 20 ms (i.e., normal operation continues). If the power loss continues for 20 ms or more, the following operations result:

• Alarm action :Continues, unless the alarm is with waiting action, in which case the alarm immediately returns to the waiting status.

• Setting parameters :The set parameters are maintained.

•Auto-tuning :Released.

If a power failure continues for 2 sec. or more, the control action upon recovery depends on the restart mode (R.MD) set in the setup parameters, as follows:

Appendix 2 Engineering Units Available for the US1000

Appendix 2 Engineering Units Avail-

able for the US1000

For the US1000, settings can be made in engineering units such as °C. The US1000 contains two categories of engineering units: “EU” and “EUS.”

■ EU

“EU” is the engineering unit for the instrument range. Use “EU” to set a target setpoint, or the upper and lower alarm limits.

The notation, “EU (-100.0 to 100.0%),” is used to indicate the range of settings that can be set for each of the parameters listed in appendices 2 and 3. That is, parameters can be set using engineering units within the -100.0 to 100.0% range of that instrument.

Example: For an instrument range of -270.0°C to 1370.0°C,

• EU (0.0%) is -270.0°C.

• EU (100.0%) is 1370.0°C.

• EU (-100.0%) is -1910.0°C.

Thus, EU (-100.0 to 100.0%) indicates a temperature range of -1910.0°C to 1370.0°C.

■ EUS

EU(-100.0%) EU(0.0%) EU(100.0%)

-1910.0°C

“EUS” is the engineering unit indicating the span of the instrument range. Use “EUS” to set a bias or deviation alarm setpoint.

The notation, “EUS (-100.0 to 100.0%),” is used for the range of settings that can be set for each of the parameters listed in appendices 2 and 3. That is, parameters can be set using engineering units within the -100.0 to 100.0% range of the instrument span.

Example: For an instrument range of -270.0°C to 1370.0°C,

• The instrument span is 1640.0°C.

•EUS (0.0%) is 0.0°C.

•EUS (100.0%) is 1640.0°C.

• EUS (-100.0%) is -1640.0°C.

Thus, EUS (-100.0 to 100.0%) indicates a temperature span of -1640.0°C to 1640.0°C.

EUS(-100.0%) EUS(0.0%) EUS(100.0%)
