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 and Connections

The controller must be fastened on a panel, following the sequence of steps described below:

• Prepare a panel cut-out according to specifications.
• Remove the mounting clamps from the controller.
• Insert the controller into the panel cut-out.
• Slide the mounting clamp from the rear for a firm grip at the panel.

Recommendations for Installation

• All electrical connections are made to the screw terminals at the rear of the controller.
• To minimize the pick-up of electrical noise, route low-voltage DC connections and sensor input wiring away from high-current power conductors. If impractical, use shielded cables. Keep cable lengths to a minimum.
• All electronic instruments must be powered by a clean mains supply, suitable for instrumentation.
• It is strongly recommended to apply RC filters (noise suppressors) to contactor coils, solenoids, etc. Consider potential system failures; the controller features alone cannot assure total protection.

Electrical Connections

Figure 01 shows the electrical terminals of the controller:

Features

Input Type Selection

Table 01 shows the sensor types accepted and their respective codes and ranges. Access the parameter 'EYPE' in the INPUT level to select the appropriate sensor.

The input type should be the first parameter configured. Modifications automatically change other related parameters. Verify configuration after any input type change.

Outputs

The controller has two outputs. Configure these outputs as Control Output (Ctrl) or Alarm Output (AL).

• OUT1: Output Voltage pulse (5 Vdc / 25 mA) or Output Relay SPST-NO
• OUT2: Output Relay SPST-NO

Control Output (Ctrl)

The control strategy can be ON/OFF (when Pb = 0.0) or PID. PID parameters can be automatically determined using the auto-tuning function (Atun).

Alarm Output (AL)

The controller has 2 alarms assignable to any output channel. Alarm functions are described in Table 02.

• OFF: Output is not used as alarm.
• Lo: Alarm of Absolute Minimum Value. Triggers when measured PV is below the value defined for alarm Setpoint (SPAL). [Diagram shows PV line below SPAL line]
• Hi: Alarm of Absolute Maximum Value. Triggers when measured PV is above the value defined for alarm Setpoint (SPAL). [Diagram shows PV line above SPAL line]
• d IF: Alarm of Differential. Parameters SPAL represent the deviation of PV in relation to the SP of CONTROL. [Diagram shows PV fluctuating around SP with SPAL indicating deviation bands]
• d IFL: Alarm of Minimum Differential Value. Triggers when PV is below the defined point by SP-SPAL. [Diagram shows PV line below SP-SPAL line]
• d IFH: Alarm of Maximum Differential. Triggers when PV is above the defined point by SP+SPAL. [Diagram shows PV line above SP+SPAL line]
• iErr: Alarms of the Sensor Break. Activated when the Input presents problems like interrupted sensor or bad connection. [Diagram shows a broken line or error symbol]

Important Note: Alarms configured with Hi, d IF, and d IFH also trigger their output on sensor fault. For example, a High Alarm (Hi) output will operate if the SPAL value is exceeded or if the sensor is broken.

Initial Blocking of Alarm

This option inhibits alarms if an alarm condition is present upon energization or transition from RUN YES to NO. The alarm is enabled only after a non-alarm condition followed by a new alarm occurrence. This is useful for minimum value alarms at start-up. Initial blocking is disabled for the 'iErr' (sensor break) function.

Offset

Allows fine adjustments to the PV reading for compensation of sensor error.

Operation

The controller's front panel is shown in Figure 02:

Display of PV / Programming: Top display (red) shows the current Process Variable (PV). In configuration mode, it shows parameter names.

Display of SP / Parameters: Bottom display (green) shows the Setpoint (SP). In configuration mode, it shows parameter values.

TUNE Indicator: Lit when the controller is in the tuning process.

OUT Indicator: Shows the actual state of the relay or pulse control output.

A1 and A2 Indicators: Signal alarm situations.

P Key: Used to navigate through menu parameters.

Increment [up arrow] and Decrement [down arrow] Keys: Alter parameter values.

Back Key: Used to go back to previous parameters.

Controller Startup

Upon power-up, the controller displays its firmware version for 3 seconds, then starts normal operation showing PV and SP values, with outputs enabled.

Parameter Configuration

For proper operation, parameters must be configured according to system requirements. Parameters are grouped into three levels:

• 1 – Tuning
• 2 – Input
• 3 – Calibration

Pressing and holding the 'P' key for 2 seconds cycles through the levels (PV >> Atun >> Type >> PASS >> PV). Release 'P' to enter a level. Short presses of 'P' navigate within a level. The ':' key goes back.

Parameters are displayed with a prompt (upper display) and value/condition (lower display). Protected levels are preceded by 'PASS'.

Parameters Description

Indication Screen

PV + SP: Displays the measured variable (PV) on the higher display (red) and the control setpoint (SP) on the lower display (green).

Tuning Cycle

Atun (AUTO-TUNE)

Enables auto-tuning for PID parameters (Pb, ir, dt). Defines the control strategy:

• OFF: Turned off (no PID tuning).
• FAST: Automatic tuning.
• FULL: More accurate automatic tuning.

Pb (Proportional Band)

Value of the P term in PID control, as a percentage of the input span. Adjustable from 0 to 500.0%. Setting to 0 enables ON/OFF control.

ir (Integral Rate)

Value of the I term in PID, in repetitions per minute (Reset). Adjustable from 0 to 99.00. Displayed only if proportional band is not zero.

dt (Derivative Time)

Value of the D term in PID, in seconds. Adjustable from 0 to 300.0 seconds. Displayed only if proportional band is not zero.

t (Level Time)

Pulse Width Modulation (PWM) period in seconds. Adjustable from 0.5 to 100.0 seconds. Displayed only if proportional band is not zero.

Hyst (Control Hysteresis)

Hysteresis for ON/OFF control (in temperature units). Used only when the controller is in ON/OFF mode (Pb=0).

A(t (Action Control)

• re: Control with Reverse Action (heating). Turns output ON when PV is below SP.
• dir: Control with Direct Action (cooling). Turns output ON when PV is above SP.

Out1, Out2 (Output Assignment)

• OFF: Not used.
• Ctrl: Control output.
• AL: Alarm output.

Input Cycle

Type (Input Type

Selects the input signal type. Refer to Table 01.

dP.po (Decimal Point Position

Selects the decimal point position for PV and SP display.

Uni t (Units)

• °C: Indication in Celsius.
• °F: Indication in Fahrenheit.

Offs (Sensor Offset

Offset value added to PV to compensate sensor error. Default: zero.

Sp.ll, Sphl (SP Limits)

Defines SP upper and lower limits for PV indication range. Does not limit Alarm SP configuration.

Fval (Functions of Alarms)

Defines alarm functions from Table 02.

Sp.al (Alarm SP)

Value defining the activation point for alarm outputs. For Differential alarms, represents deviations. No meaning for 'iErr' alarm.

Blal (Blocking Alarm)

• YES: Enables initial blocking.
• NO: Inhibits initial blocking.

Hyal (Hysteresis of Alarm)

Defines the difference between PV values for alarm triggering and turning off.

Calibration Level

Inputs are factory calibrated. Recalibration requires a specialized professional. Do not alter parameters if unfamiliar.

• Pass: Password prompt before protected levels.
• Cal: Enables calibration. Related parameters are hidden if disabled.
• InLc (Input Low Calibration): Enter value for low scale signal.
• InHc (Input High Calibration): Enter value for full scale signal.

• rstr (Restore): Restores factory calibration for all inputs/outputs.
• Pasc (Password Change): Define a new access password (must be different from zero).
• Prot (Protection): Sets the Protection Level (see Table 03).

Configuration Protection

Protects parameters from unauthorized modifications. The 'Prot' parameter in the Calibration level determines protection strategy (access to levels).

Access Password

Protected levels require an Access Password. If no password is entered, parameters can only be viewed. The password is set via 'Pasc' and defaults to 1111.

Protection Access Password

The system blocks access to protected parameters for 10 minutes after 5 consecutive incorrect password attempts.

Master Password

Allows defining a new password if forgotten. It only grants access to the 'Pasc' parameter. The master password is formed by the last three digits of the serial number plus 9000 (e.g., serial 07154321 -> master password 9321).

Controller serial number is displayed by pressing [P] for 3 seconds.

Determination of PID Parameters

Auto-tuning determines PID parameters automatically. The process involves system oscillations and output switching. It may take several minutes.

Auto-Tuning Steps:

• Select the process Setpoint.
• Enable auto-tuning via the 'Atun' parameter, selecting 'FAST' or 'FULL'. 'FAST' prioritizes speed, 'FULL' prioritizes accuracy.

The 'TUNE' indicator remains lit during tuning. Wait for completion before use.

If tuning is unsatisfactory, refer to Table 04 for manual adjustment guidelines.

Maintenance

Problems with the Controller

Common errors are connection issues and inadequate programming. Reviewing these can prevent issues.

The controller displays messages to help identify problems:

• Err 1: Open input. No sensor or signal.
• Err 6: Connection and/or configuration problems. Check wiring and configuration.

Other error messages may indicate hardware problems requiring service.

Process Variable Input Calibration

Inputs are factory calibrated. Recalibration requires qualified personnel. Do not attempt if unfamiliar.

1. Set the input type parameter according to the input (EYPE).
2. Configure lower and upper limits for the selected input span.
3. Access the calibration level.
4. Enter the password.
5. Enable calibration setting 'YES' in the 'CAL' parameter.
6. Using an electrical signal simulator, apply a signal level near the lower limit of the measuring range to the corresponding terminals.
7. Access the 'InLc' parameter. Use the [up arrow] and [down arrow] keys to adjust the display to match the applied signal. Press [P].
8. Apply a signal corresponding to a value slightly below the upper indication limit.
9. Access the 'InHc' parameter. Use the [up arrow] and [down arrow] keys to adjust the display to match the applied signal. Press [P] until returning to the PV display screen.
10. Validate the calibration.

Note for Pt100 calibration: Ensure the simulator's minimum excitation current is compatible with the controller's 0.170 mA.
