N1030 Temperature Controller

Safety Alerts

The symbols below are used on the equipment and throughout this document to draw the user's attention to important operational and safety information.

CAUTION: Read the manual thoroughly before installing and operating the equipment.

CAUTION OR DANGER: Electrical shock hazard.

All safety related instructions that appear in the manual must be observed to ensure personal safety and to prevent damage to either the instrument or the system. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Installation / Connections

The controller should be fixed to a panel, following the sequence of steps below:

• Make a cutout in the panel according to the Specifications.
• Remove the controller fixing clip.
• Insert the controller into the cutout from the front of the panel.
• Replace the clip on the controller, pressing until it is well fixed.

Installation Recommendations

• Input signal conductors should run through the plant separately from output and supply conductors. If possible, in grounded conduits.
• The power supply for electronic instruments must come from a network dedicated to the instrumentation.
• The use of RC FILTERS (noise suppressors) in contactor coils, solenoids, etc. is recommended.
• In control applications, it is essential to consider what can happen when any part of the system fails. The controller's internal devices do not provide full protection.

Electrical Connections

The figure below shows the connections on the back panel of the controller:

Features

Temperature Sensor (Input)

The temperature sensor or input type to be used by the controller is defined during equipment configuration. Table 01 shows the available options:

Table 1 - Input types

The input type should be the first parameter to be configured. Any modifications on the input type will automatically change other related parameters. When changing the sensor type, you should check the overall condition of the configuration.

Outputs

The controller has two outputs. You can configure these outputs to operate as Control Output (Ctrl) or Alarm Output (A1).

• OUT1: N1030-PR: Output voltage pulse, 5 Vdc / 25 mA; N1030-RR: Output Relay SPST-NO
• OUT2: Output Relay SPST-NO

Control Output (Ctrl)

The process control output can operate in ON/OFF mode or in PID mode.

To operate in ON/OFF mode, the value set in parameter Pb must be 0.0.

With values other than zero in parameter Pb, the controller operates in PID mode. The values for the PID parameters can be set automatically with the help of Auto Tune (Atun).

Alarm Output (A1)

The controller has an alarm that can be directed to any of the outputs. When enabled, you can configure the alarm to operate with one of the functions described in Table 02:

• OFF: Alarm off.
• Lo: Alarm of absolute minimum value. It triggers when the value of measured PV is below the value defined for alarm Setpoint (SPA1).
• HI: Alarm of absolute maximum value. It triggers when the value of measured PV is above the value defined for alarm Setpoint (SPA1).

Table 2 - Alarm functions

Important note: Alarms configured with the H1, d IF, and d IFH functions also trigger their associated output when a sensor fault is identified and signaled by the controller. A relay output, for example, configured to function as a Higher Alarm (H1), will operate when the SPA1 value is exceeded and when the sensor connected to the controller input is broken.

Alarm Initial Blocking

The Initial Blocking option inhibits the alarm from being triggered if an alarm condition exists when the controller is turned on. The alarm is triggered only after the process goes through a non-alarm condition.

The initial blocking is useful, for example, when one of the alarms is configured as a minimum value alarm, which can cause the alarm to be triggered as soon as the process is started (a behavior that is often undesired).

The initial block is not valid for the Err function.

Offset

Function that allows you to make a small adjustment to the PV indication. Allows you to correct measurement errors that appear, for example, when replacing the temperature sensor.

Operation

The front panel of the controller can be seen in the figure below:

[Diagram: Front panel identification showing Display, Keys (TUNE, RUN, OUT, A1, A2), and indicators for TUNE, OUT, A1, A2.]

Figure 2 - Front panel identification

• Display: Displays the measured variable, configuration parameter symbols and their respective values/conditions.
• TUNE Indicator: Stays on while the controller is in tuning process.
• OUT Indicator: Signals the control output(s) status.
• A1 and A2 Indicators: Signal the occurrence of an alarm condition.

Keys

• P Key: Key used to advance the successive parameters and parameter cycles.
• Key: Increment key and parameter values.
• Key: Decrement key: Keys used to change parameter values.
• Back Key: Key used to move back parameters during configuration.

Operation

When turned on, the controller shows the software version for the first 3 seconds, then it shows the value of the measured process variable (PV) in the upper display. In the lower display, it shows the SP value. This is the Indication Screen.

To be used in a process, the controller must be previously configured. To configure it, each of the various parameters presented must be defined. You must understand the importance of each parameter and determine a valid condition or value.

The configuration parameters are gathered in affinity groups, called parameter cycles. The 3 parameter cycles are:

1. Tuning
2. Input
3. Calibration

The P key gives access to the cycles and their parameters. By keeping the P key pressed, every 2 seconds the controller jumps from one cycle to another, presenting the first parameter of each cycle: PV >> Atun >> EYPE >> PASS >> PV. To enter the desired cycle, simply release the P key when the first parameter is displayed. To move forward through the parameters of that cycle, use the P key. To go backwards through the parameters, use the key.

The symbol of each parameter is shown in the upper display. Its respective value/condition is shown in the lower display. Depending on the configuration protection that you have adopted, the PASS parameter is shown as the first parameter of the cycle where the protection starts. See Configuration Protection chapter.

Parameters Description

Indication Screen

• PV: Temperature indication screen. The upper (red) display shows the value of the measured variable (PV) temperature.
• SP: The lower display (green) shows the control setpoint value (SP), which is the desired value for the process temperature.

(*) This parameter is not displayed when the alarm function is set to OFF or Err.

(**) This parameter is not available for version 1.0x of the controller.

Calibration Cycle

All input types are calibrated at the factory. If a recalibration is necessary, it must be performed by a specialized professional. If this cycle is accessed accidentally, do not promote changes in its parameters.

• PASS: Password. This parameter is shown before the protected cycles. See Configuration Protection chapter.
• CAL: Calibration. Allows you to enable the function to calibrate the controller. When the function is not enabled, the calibration of the related parameters will remain hidden.
• InLC: Input Low Calibration. Allows you to enter the value corresponding to the low scale signal applied to the analog input.
• InHC: Input High Calibration. Allows you to enter the value corresponding to the full-scale signal applied to the analog input.
• Str: Restore. Allows you to reset the input factory calibrations, disregarding all changes made.
• PASC: Password Change. Allows you to set a new access password, always different from zero.
• Prot: Protection. Allows you to define the protection cycle. See Table 03.

Configuration Protection

The controller allows you to protect its configuration, preventing undue changes. In the Calibration cycle, the Protection parameter (Prot) determines the protection cycle to be adopted, limiting access to the cycles, as shown in the table below:

Table 3 - Protection cycles

Access Password

To access the Calibration cycle, a password is required. If entered correctly, it allows changing the configuration of the parameters of these cycles, including the Protection parameter (Prot). You can set the password in the Password Change parameter (PAS.C), which is also present in the Calibration cycle. The controllers leave the factory with the password set to 1111.

Protection Access Password

The controller has a security system that helps prevent the entry of numerous passwords to guess the correct password. Once 5 consecutive invalid passwords are identified, the controller stops accepting passwords for 10 minutes.

Master Password

If you forget the password, you can use the Master Password feature. When entered, this password gives access and allows changing the Password Change parameter (PASC). This makes it possible to set a new password for the controller. The master password is formed by the last three digits of the controller serial number plus the number 9000. Example: For a device with serial number 07154321, the master password is 9321. You can get the serial number of the controller by pressing the key for 5 seconds.

PID Parameters Definition

During auto-tuning, the process is controlled in ON/OFF mode at the programmed setpoint (SP). In some processes the auto-tuning can take many minutes to complete. The recommended procedure for its execution is:

• Set the desired SP value for the process.
• On the Atun screen, enable automatic tuning by selecting FASE or FULL.

The FASE option performs the tuning in the minimum possible time. The FULL option prioritizes a more precise tuning.

During automatic tuning, the TUNE indicator remains lit on the front of the controller. You must wait until the tuning is finished before you can use the controller.

During the execution of the automatic tuning, it is possible to induce PV oscillations in the process around the setpoint.

If the tuning does not result in satisfactory control, Table 04 presents guidelines on how to correct the process behavior.

Maintenance

Problems with the Controller

Wiring errors and improper programming represent most of the problems that can occur when using the controller. A final review can avoid wasted time and losses.

The controller presents some messages that are intended to help you identify problems.

Table 5 - Error messages

Other error messages displayed by the controller represent internal damages that necessarily imply sending the equipment for maintenance.

Input Calibration

All controller input types leave the factory already calibrated. Recalibration is not recommended for inexperienced operators. If it is necessary to recalibrate an input, proceed as follows:

1. In the EYPE parameter, set the input type to be calibrated.
2. Program the lower and upper SP limits for the extremes of the input type.
3. Access the Calibration cycle.
4. Enter the access password.
5. In parameter CAL, enable the calibration by setting YES.
6. With an electrical signal simulator, apply to the input terminals a signal near the lower limit of the configured input measurement range.
7. In the LC parameter, use the and keys to make the display indicate the expected value for the applied signal. Then press the P key.
8. Validate the calibration.

Note: When checking the controller calibration with a Pt100 simulator, pay attention to the simulator minimum excitation current requirement, which may not be compatible with the 0.170 mA excitation current provided by the controller.

h) Apply a signal near the upper limit of the configured input measurement range to the input terminals.

i) In the inHC parameter, use the and keys to make the display indicate the expected value for the applied signal. Then, press the P key until returning to the Temperature Indication Screen.

j) Validate the calibration.
