1 Introduction

The process controller CN40x stands out for the bright display which ensures optimal visibility and increased level of information for the operator beside a scrolling Help function. CN40x relies on Omega programming mode by NFC/RFID technology with dedicated App Direct link | 400S Devices for Android devices not requiring wirings and power supply, allowing quick set-up/ updates on site. Availability include a model with dual analogue input and dual analogue output for maximum ﬂexibility of applications. It is possible to achieve two separate heating/cooling PID control loops in one device or to handle mathematical operations between two process values. The outputs can be selected as command/multiple alarm modes/analogue retransmission. Serial communication standard is RS485 with Modbus RTU/Slave protocol. Useful power supply with extended range 24 to 230VAC / VDC with galvanic insulation of the net for the single loop version, while the model with double analogue input provides two versions: 115 / 230 VAC or 24 VAC / VDC.

2 Safety guidelines

Disconnect power supply before proceeding to hardware settings or electrical wirings to avoid risk of electric shock, ﬁre, malfunction. Do not install/operate the device in environments with ﬂammable/explosive gases. This device has been designed and conceived for industrial environments and applications that rely on proper safety conditions in accordance with national and international regulations on labour and personal safety. Any application that might lead to serious physical dama ge/ life risk or involve medical life support devices should be avoided. Device is not conceived for applications related to nuclear power plants, weapon systems, ﬂight control, mass transportation systems. Only qualiﬁed personnel should be allowed to use device and/or service it and only in accordance to technical data listed in this manual. Do not dismantle/modify/repair any internal component. Device must be installed and can operate only within the allowed environmental conditions. Overheating may lead to risk of ﬁre and can shorten the lifecycle of electronic components.

2.1 Organization of safety notices

Safety notices in this manual are organized as follows:

Safety notice Description

Danger! Disregarding these safety guidelines and notices can be life-threatening.

Warning!

Information! This information is important for preventing errors.

Disregarding these safety guidelines and notices can result in severe injury or substantial damage to property.

2.2 Safety Precautions

This product is UL listed as open type process control equipment. Danger! If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions. Loose screws may occasionally result in ﬁre. For screw terminals of relays and of power supply, tighten screws to tightening torque of 0,51 Nm. For other terminals, tightening torque is 0,19 Nm

Danger!

Warning!

User manual - CN40x- 5

A malfunction in the Digital Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Digital Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

Warning!

2.3 Precautions for safe use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse aﬀects on the performance and functions of the product. Not doing so may occasionally result in unexpected events. Do not handle the Digital Controller in ways that exceed the ratings.

• The product is designed for indoor use only. Do not use or store the product outdoors or in any of

the following places.

- Places directly subject to heat radiated from heating equipment.

- Places subject to splashing liquid or oil atmosphere.

- Places subject to direct sunlight.

- Places subject to dust or corrosive gas (in particular, sulﬁde gas and ammonia gas).

- Places subject to intense temperature change.

- Places subject to icing and condensation.

- Places subject to vibration and large shocks.

• Installing two or more controllers in close proximity might lead to increased internal temperature

and this might shorten the life cycle of electronic components. It is strongly recommended to install cooling fans or other air-conditioning devices inside the control cabinet.

• Always check the terminal names and polarity and be sure to wire properly. Do not wire the

terminals that are not used.

• To avoid inductive noise, keep the controller wiring away from p ower cables that carry high voltages

or large currents. Also, do not wire power lines together with or parallel to Digital Controller wiring. Using shielded cables and using separate conduits or ducts is recommended. Attach a surge suppressor or noise ﬁlter to peripheral devices that generate noise (in particular motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). When a noise ﬁlter is used at the power supply, ﬁrst check the voltage or current, and attach the noise ﬁlter as close as possible to the Digital Controller. Allow as much space as possible between the Digital Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

• A switch or circuit breaker must be provided close to device. The switch or circuit breaker must be

within easy reach of the operator, and must be marked as a disconnecting means for the controller.

• The device must be protected by a fuse 1A (cl. 9.6.2).

• Wipe oﬀ any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine,

alcohol, or any cleaners that contain these or other organic solvents. Deformation or discoloration may occur.

• The number of non-volatile memory write operations is limited. Therefore, use EEprom write mode

when frequently overwriting data, e.g.: through communications.

2.4 Environmental policy / WEEE

Do not dispose electric tools together with household waste material. According to European Directive 2002/96EC on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

To avoid an overshoot, the treshold where the controller calculates new PID parameters is determined by this operation: Tune threshold = Setpoint Ex.: if the sepoint is 100.0∞C and the Par.32 is (100.0 - 20.0) = 80.0∞C. For a greater precision on PID parameters calculation it is suggested to start the manual tuning procedure when the process deviates from the setpoint.

User manual - CN40x- 15

9.5 Synchronized tuning

Set sYNch. on parameter 73 t u n .1 or on parameter 98 tun .2. This procedure has been conceived to calculate correct PID values on multi-zone systems, where each temperature is inﬂuenced by the adjacent zones. Writing on word modbus 1216 (for regulation loop 1) or 1217 (for regulation loop 2) the controller works as follows:

Word value Action

0 Tune oﬀ 1 Command output OFF 2 Command output ON 3 Tune active 4 Tune completed: command output OFF (read only) 5 Tune not available: softstart function enabled (only reading)

Here below the functioning for regulation loop 1: the master switches-oﬀ or turns-on all zones (value 1 or 2 on word 1216) for a time long enough to create inertia on the system. At this point the autotuning is launched (value 3 on word 1216). The controller executes the procedure for the calculation of the new PID values. When the procedure ends, the controller switches oﬀ the command output and selects the value 4 on word 1216. The master, who will always read the word 1216, will control the various zones and when all will have ﬁnished, will bring to 0 the value of word 1216: the various devices will regulate the temperature independently, with the new calculated values. N.B. The maste r must read the Index 0x400E at leas t every 10 seconds or the controller will automatically exit the autotuning procedure.

CN40x is suitable also for systems requiring a combined heating-cooling action. The command output has to be conﬁgured as PID for Heating (Par. 38

P. b . 1 or P. b . 2 greater than 0), and one of the alarms (A L .1 . F. , AL.2. f., AL.3 . f. , AL.4 . f . , A L.5. f . or A L. 5.F. ) has to be

conﬁgured as

co o L.

The command output must be connected to the actuator responsible for heating, while the alarm will control cooling action. Parameters to be conﬁgured for the heating PID are:

a c . t .1 or a c. t.2 = Heat Command output action type (Heating); P.b . 1 or p. b . 2: Heating proportional band; i .t . 1 or i. t. 2: Integral time of heating and cooling; d .t . 1 or d.t. 2: Derivative time of heating and cooling; c. t. 1 or c.t. 2: Heating time cycle.

Parameters to be conﬁgured for the cooling PID related to regulation loop 1 and alarm 1 are:

A L .1 . F. = co oL. Alarm 1 selection (Cooling); p.b.m.1: Proportional band multiplier; o.d.b.1: Overlapping / Dead band; c. c.t .1: Cooling time cycle.

Par.

p.b.m.1 (that renges from 1.00 to 5.00) determines the proportional band of

cooling action basing on the formula: Proportional band for cooling action =

p. b. 1 x p.b.m.1.

This gives a proportional band for cooling which will be the same as heating band if p.b.m.1 = 1.00, or 5 times greater if

p.b.m.1 = 5.00.

Integral and derivative time are the same for both actions. Par.

o.d.b.1 determines the percentage overlapping between the two actions. For systems in which

the heating output and cooling output must never be simultaneously active a Dead Band ( must be conﬁgured, vice versa you can conﬁgure an overlapping ( The following ﬁgure shows an example of dual action PID (heating-cooling) with

Address 255 can be used by the Master to communicate with all the connected equipment (broadcast mode), while with 0 all the devices receive the command, but no response is expected. The baud rate is selected on parameter 319 CN40x can introduce a delay (in milliseconds) of the response to the master request. This delay must be set on parameter 321 Each parameter modiﬁcation is saved by the controller in the EEPROM memory (100000 writing cycles), while the setpoints are saved with a delay of 10 seconds after the last modiﬁcation. Changes made to words that are diﬀerent from those reported in the following table can lead to malfunction.

11 Reading and conﬁ guration through NFC

Scan the Qr-Code

to download the App

on Google Play Store®

The controller CN40x is supported by the App Direct link | 400S Devices: using an ANDROID smartphone with NFC connection it is possible to program the device without using a dedicated equipment. The App allows to read, set and backup all parameters which are stored into the internal memory of Omega devices.

Procedure:

• Identify the position of the NFC antenna on the smartphone (usually central, behind the back cover) or to one of the sides in case of metal chassis. The CN40x’s antenna is placed on the frontal panel, under the function keys.

• Make sure that the NFC sensor of the phone is enabled or that there are no metal materials between the phone and the device (ex. aluminium cover or with magnetic stand)

• It is useful to enable the system sounds on the smartphone, as the notiﬁ cation sound conﬁ rms that the device has correctly been detected.

The App interface is provided with four tabs: SCAN, DATA, WRITE, EXTRA.

Select the ﬁ rst tab smartphone in contact with the controller frontal panel, making sure that the phone’s antenna matched with that of the controller. Once detected the device, the App emits a notiﬁ cation sounds and proceeds with the model identiﬁ cation and the reading of the parameters.

The graphic interface shows the advancement and switches to the second tab to move the smartphone away from the controller to make the required modiﬁ cations more easily. The device parameters are divided into collapsible groups and are displayed with name, current value and reference index to the manual. Click on a row to open the setting screen of the related parameter with the detailed view of available options (in case of multiple choice parameters) or of the minimum/maximum/decimals limits (for numeric parameters), included the text description (as per section n. 11 of the user manual). Once selected the chosen value, the related row will be updated and underlined into the tab down the line to cancel modiﬁ cations).

To download the new conﬁ guration on your device, select the third tab smartphone in contact with the controller and wait for the notiﬁ cation.

12.2 Parameters list functioning

The controller CN40x integrates many features that make the conﬁguration parameters list very long. To make it more functional, the parameters list is dynamics and it changes as the user enables / disables the functions. Practically, using a speciﬁc function that occupies a given input (or output), the parameters referred to other functions of that resource are hidden to the user making the parameters list more concise. To simplify the reading/interpretation of the parameters, pressing SET it is possible to visualize a brief description of the selected parameter. Finally, keeping pressed FNC, it is possible to move from the mnemonic visualization of the parameter to the numeric one, and vice versa. Ex. The ﬁrst parameter can be displayed as visualization) or as Set the product parameters so that they are suitable for the system to be controlled. If they are not suitable, unexpected operations may occasionally cause materials damage or accidents.

Notes / Updates

1 Display of decimal point depends on setting of parameter sen. and parameter d . p. 2 On activation, the output is inhibited if the controller is in alarm mode. Activates only if alarm condition reappers, after that

it was restored.

3 Changing the control setpoint, the alarm will be disabled. It will stay disabled as long as the parameters that created it are

active. It only wo rks with deviation alarms, band a larms and absolute alarms (referring to the control setpoint).
