C-PRO NANO RACK AND C-PRO MICRO RACK APPLICATION MANUAL

1 GENERALITIES

1.1 Description

This application uses control units of C-PRO NANO and C-PRO MICRO line for management of a refrigerator compressor pack composed by one or two circuits with maximum number of 4 compressors. The function required to a refrigerator compressor pack’s control system is the management of the compressors for the maintenance of the evaporation pressure up to the wished value; in deeper words it must assure the production of cold, for example for foodstuffs’ conservation. Therefore it is required the continuous generation of cold through an action that must take place without interruptions, unless for normal maintenance operations.C-PRO NANO and C-PRO MICRO control units are extremely careful to these aspects managing all the circuit’s parts with the best possible efficiency (better efficiency output = less operation costs), handling the mechanical tools in the best way, for breakdown reduction (for example less trimming = less mechanical stress). For the control of pressure or temperature it is possible to choose between two setting types:

⋅ Sideband ⋅ Neutral zone

For each circuit the safeties are managed in order to signalize promptly the possible malfunctions. To each safety it is associated a particular alarm that will be signalized in order to identify the type of breakdown. Some alarms will consequently block the mechanical devices in order to avoid further breakdown. Other alarms, as a result, will only signalize without taking any measure over the machine’s operation. The application has a navigable user inteface whereby it is possible defining and setting all the configuration and operation parameters divided into four main levels:

⋅ User ⋅ Maintenance operative ⋅ Installer ⋅ Contructor

Each level is protected by a different password. On contructor’s level the user inteface displays a range of editable configuration templates (wizard) that allow to set easily the number of circuits, compressors, fans and the respective safeties that we want to use in order to protect the mechanical devices. There is always a TTL output for the connection to RICS supervision system (through aTTL/RS-485 user interface) or to other BMS.

4.2 Pages list

⋅ In this paragraph there will be a presentation of the main pages and of the menus contained in the

application manual. Like previously explained, the general menu is divided into four levels: user, maintenance operative, installer,constructor.

The structure of the menu is the following:

⋅ General Menu

⋅ User menu (Level 1) ⋅ Maintenance Operative Menu (Level 2)

o Maintenance operative menu operation field o Maintenance operative menu manual field o Maintenance operative menu input/output field

⋅ Installer Menu (Level 3)

o Installer menu adjustments field o Installer menu compressor field o Installer menu fans field o Installer menu safeties field o Installer menu variety field

⋅ Constructor Menu (Level 4)

o Constructor menu plant field (configuration wizard) o Constructor menu hardware field o Constructor menu parameters field

Password

To each menu it is associated a level that conditions the accessibility to the various menus. To each level it is associated a password that allows to enter the various features in that particular menu, once the correct password is typed, the protected features will be able to be entered. Typing correctly a password, we have two effects:

⋅ unblocking of the correlated level ⋅ unblocking of the sublevels

Each level password can be modified from the same level or from superior levels. For example from constructor level all the passwords of lower levels will be able to be modified using the proper page. The range of values that can be set by the password is -999 / 9999. If no key is pressed after 4 minutes, the password expires and it is necessary to set it again.

Main page

The main screen is different if the machine status is switched on or off:

- if the machine is switched off, the word OFF is displayed, or OFFd if the cause of the switching

off is due to supervision. If the cause of the switching off is the missing consent by digital input or OFFS if the cause of switching off is due to supervision

- if the machine is switched on, the value of suction pressure is displayed (or the label

probe is damaged or not-connected)

With the machine switched on, through UP/DOWN keys, it is possible to see the values of the various probes.

Installer Menu

The installer menu is of level 3, it is then necessary to insert the installer level or builder password in order to see/modify the parameters in this branch.

reG1 ( CIRCUIT 1 SETTINGS Menu) reG2 ( CIRCUIT 2 SETTINGS Menu ) CoMP (COMPRESSORS Menu) FAn (FANS Menu) SEcu (SECURITIES Menu ) Par (VARIOUS PARAMETERS Menu) MAP (PARAMETERS MAPS Menu ) PSd3 (INSTALLER Password Menu )

In installer menu there are all the parameters concerning the configuration of all the functions (alarms, adjustments, logics, rotation type, … ) of the machine.

In ADJUSTMENTS it is possible to adjust/see the parameters concerning the sideband and neutral zone thermoregulations for compressors and fans.

In COMPRESSORS and FANS menu it is possible to set the parameters concerning devices management:

⋅ rotation ⋅ logic of divisions ⋅ times…

In SECURITIES menu there are all the parameters regarding the alarms and securities management for compressors and fans

⋅ habilitations ⋅ delays in signalling ⋅ reinforcement type…

In VARIOUS PARAMETERS there are other general parameters regarding Modbus communication management, the bottom values for transducers and other habilitations that can be adjusted.

The PARAMETERS MAPS menu can be reached only from the machine in OFF status. In this menu it is possible to restore the factory parameters and to save or reload the parameters from a programming flashdrive key. After every operation it is necessary to switch off and switch on again the tool.

Constructor Menu

The constructor menu is of level 4, it is necessary then to insert the constructor level password in order to see/modify the parameters in this branch. Besides it can be reached only from the machine in OFF status.

ConF ( CONFIGURATION Menu) Hard (HARDWARE INPUTS/OUTPUTS Menu) ) PSd4 (CONSTRUCTOR Password)

This menu contains all the machine’s configuration parameters that decide its operation way and which functions habilitating or inhibiting according to the constructor’s needs.

The CONFIGURATION menu contains a plant configuration “wizard” to set the number of circuits, the presence of compressors or fans controlled through inverter, the number of compressors and respective divisions, the number of fans and the number of safeties to be used.

HARDWARE menus contain all the parameters for adjustment of positions to which connecting the various devices.

⋅ Compressors’ digital outputs position ⋅ Fans’ digital outputs position ⋅ Inverter position to be connected to analogue outputs ⋅ Alarms’ digital inputs/outputs position

Note: Adjusting the positions of alarm’s various inputs, their functionality is set as well. In fact an alarm is enabled only if the parameter that identifies its physical position on the clamp is set and is different from zero. If we do not want to use an alarm, just let the corresponding parameter in zero value. The same management is used for outputs management, for example of alarm relays: if the parameters are equal to zero, the controls of the relays are disabled.

Firmware and project versions

Press buttons UP and DOWN at the same time 2 s; later, press ENTER when the label InFo is shown. The display will show in succession the information on the project and firmware versions of the controller, as follows: Project number <-> Project version <-> Project revision <-> Firmware number <-> Firmware version <-> Firmware revision. To scroll the information, use buttons UP and DOWN. To go back to the application pages, press button ESC.

4.3 Conditioned visibility

The conditioned visibility allows to hide configuration parameters and status according to particular configurations. For example: if the kind of regulation is Neutral Zone, configuration parameters about Side Band will automatically be hidden. Another example: if you have set the controller in order to control a mono-circuit compressor pack, all configuration parameters about the second circuit will automatically be hidden. In other words, all not relevant configuration parameters will not be shown by the user interface. This function make easier the set up, the maintenance and the use of the controller. During the configuration, once chosen the kind of compressor pack, not relevant configuration parameters will not be accessible. During the maintenance, you can test the device really present.

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

Last but not least, conditioned visibility allows to avoid showing plenty of parameters; the display will only show relevant configuration parameters. In the configuration parameters table, one has signalled configuration parameters which visibility depends on this function and the condition setting the visibility.

6 ADJUSTMENTS

6.1 Configuration of the machine

Using a wizard (Constructor menu), it is possible to configure the machine with help. The first choice involves the number of circuits (1 or 2) through the parameter PG01; in the case of a bi-circuit, the choice of condensation type, either singular or separate (PG30), becomes important as does the presence or absence of expansion (PG02). These 3 parameters define the type of machine and the hardware that supports it, as is shown in the following table.

(*) Note: Temperature is transformed into pressure by selecting the type of cooling (coolant) gas that is used (parameter PH31).

Using the same wizard, the number of compressors and fans for each circuit are also set, as is the presence of the inverter for the compressors and fans, the number of throttlings and safety measures for the compressors and the activation of the fans. A check will verify whether the necessary hardware resources for the machine type are sufficient or not, generating an eventual AH01 hardware configuration alarm.

Note: Enabling the inverter for the adjustment of the compressors, the FIRST compressor will be the one controlled by the inverter, while any other subsequent compressors will be sealed (without throttlings) and will be controlled by digital relay output. Similarly, enabling the inverter for the adjustment of the fans, the FIRST fan will be the one controlled by the inverter, while any other subsequent fan with be controlled by digital relay output. For each inverter it must be configured the position of the device activation consent digital outputs.

6.2 Status of the machine and of the single circuits

There are multiple procedures for turning on/shutting off the unit or the single circuit:

1) By using the appropriate On/Off button (function enabled by parameter PH05)

Turning On – push the ESC button for about 2 seconds: if all other enabled conditions are present, the machine will go to “ON”. Shutting Off – push the ESC button for about 2 seconds: the machine will go to “OFF”.

2) By using the On/Off by digital input command (function enabled by parameter PH07 for the machine

and PH08 for the circuits) Turning On – close the remote On/Off contact; if all the other enabled conditions are present, the machine or single circuit will go to “ON”. Turning Off – if the remote On/Off contact is open, the machine or single circuit will go to “OFF by digital input”, represented with the saying “OFFd”.

3) Using the supervision protocol (function enabled by parameter PH09 for the machine and PH10 for the

circuits) Turning On – activate the “on” by protocol status: if all the other enabled conditions are present, the machine or single circuit will go to “ON”. Turning Off – if the “on” by protocol status is deactivated, the machine or the single circuit will go to “OFF by supervision protocol”, represented with the saying “OFFS”.

The On/Off by button status has the priority over the other two methods, indeed, the Off by digital input and by supervision protocol states can be reached only if the machine is on.

A machine that is turned off by digital input will be able to:

1 pass to the Off by button status (by pressing the appropriate button) 2 pass to the Off by supervisor status (if the digital input is open and if the Off by supervisor status is set) 3 turn on (if the digital input is closed and the Off by supervisor status is not set)

A machine that is turned off by supervision protocol will be able to:

4 pass to Off by button status (by pressing the appropriate button) 5 pass to the Off by digital input status (if it is set by means of the supervisor and if the digital input is

open)

6 turn on (if the digital input is closed and the Off by supervisor status is not set)

The machine’s On/Off button is the ESC button. The remote On/Off inputs (when they are present) are configured by means of the appropriate parameters:

1 Hd01 = position of remote On/Off digital input for the machine 2 Hd11 = position of remote On/Off digital input for circuit 1 3 Hd21 = position of remote On/Off digital input for circuit 2

6.3 Adjustment of the compressors

Checking the suction pressure of the compressors implies the management of the compressors to reach and maintain a certain operating pressure value: according to the type of check (sideband adjustment or neutral zone adjustment) and the use or lack thereof of the inverter for a finer adjustment, four types of adjustment are considered.

6.3.1 Sideband adjustment

The sideband check uses the characteristics of the PI regulators (proportional and integral) or of the P regulators (proportional) to establish when to plug in or unplug the compressors being used, in order to regularize, within the differential range, the turning on or off of the various devices. The parameters relative to the first circuit are the following:

1 SPC1 = Setpoint compressors (SP) 2 PC14 = Type of adjustment = 0 3 PC16 = Integral time (TI) 4 PC17 = Sideband (BP) 5 PG11 = Number of compressors 6 PG04 = Number of throttlings

The number of compressors and the number of throttlings supplies the Maximum Number of Steps with which the proportional band is divided. The purpose of the Proportional +Integral adjustment is to obtain a null error in this type of scheme.

The image above shows the behavior of the proportional band adjustment (SP, SP +BP). Based on the value of the suction pressure, the adjustment adds or subtracts the number of steps that are required of the compressors. In this adjustment, the band is entirely moved above the setpoint.

It is possible to choose whether the check will refer to the PI or only to the P adjustment, by setting the parameter for the integral action, which is the integration time (Ti). Specifically, if this parameter is set to a value of zero, the adjustment is only proportional, otherwise it also becomes integral. The Ti corresponds to the time needed by the integral action to be equal to the proportional action, given the hypothesis of a constant error: the speed of this action is proportionally linked to the value of the integration time. The default parameter is worth 600 seconds, and so the adjustment takes advantage of the proportional + integral characteristic.

Through the PC78 Sideband steps overlapping factor, it is possible to improve the behavior of this type of adjustment, which requires wide proportional bands in order to be stable, by modifying the subdivision of the adjustment band of adjustment between the steps:

Inserimento

PC78 %

SP SP + BP

Max Gradini

Aspirazione

Steps will be loaded at PC78% of the proportional band; the steps will be unloaded at 100 – PC78% of the proportional band. If for example PC78 has value 60%, the steps will be loaded between 60% of the proportional band and its maximum value (100%); steps will be unloaded between 40% of the proportional band and its minimum value (0%). It appears clear that by using such a division of the steps as indicated in the image, the interval of activity of each single step is higher than the classical geometrical division, with the clear advantage that the proportional band may be diminished, to favor a higher precision of adjustment, and/or the activations of the steps occur less frequently, that is, the breakaways of the compressors decrease, favoring the mechanical duration of the compressors themselves.

6.3.2 Neutral zone adjustment

This adjustment implies the definition of a neutral zone in which no decision of activation or deactivation will be made, which means that no breakaways will be required for any device.

The parameters relative to the first circuit are the following:

7 SPC1 = Setpoint compressors (SP) 8 PC14 = Type of adjustment = 1 9 PC18 = Neutral Zone (NZ) 10 PC19 = Differential outside the neutral zone (diff) 11 PC20 = Minimum time of Turn-on (TOnMin) 12 PC21 = Maximum time of Turn-on (TOnMax) 13 PC22 = Minimum time of shutdown (TOffMin) 14 PC23 = Maximum time of shutdown (TOffMax)

Outside the neutral zone, the turn-on or shutdown requests for the various steps supplied by the compressors will follow this logic:

1 Turn-on: when the pressure of suction exceeds the threshold value setpoint + neutral zone 2 Shutdown: when the pressure goes below the setPoint

In this type of adjustment, the neutral zone is found entirely to the right of the setPoint.

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

As we can see from the figure, the adjustment foresees the setting of certain timings within which, depending on the zone, the turn-on and shutdown requests for the various steps must be adjusted to work according to established time intervals. Based on the difference between the actual suction pressure value and the reference value, the times will vary proportionally according to the values set. The reference value mentioned represents, according to the case, the right and left limit of the neutral zone with the addition of another differential (which can be set through a parameter) within which the proportional variation of the time in question will be found. At the limits of the adjustment, the values of the turn-on and shutdown times are the maximum and minimum times that are established by the parameter. To render the request time constant during the turn-on phase, it is enough to set the NZ TOnMin and the NZ TOnMaz parameters to the same value. The same thing is true for the shutdown phase.

6.3.3 Sideband adjustment with inverter

This check adds an inverter adjustment to the normal sideband adjustment; in order to do this, it is necessary to set some parameters relative to the inverter device that is to be used, besides enabling its use.

The parameters relative to the first circuit are the following:

- SPC1 = Setpoint compressors (SP)

- PC14 = Type of adjustment = 0

- PG12 = Activation of the inverter

- PC24 = Inverter differential (DI)

- PC25 = Inverter offset with respect to the suction setPoint (OFSI)

- PC26 = Minimum value of inverter (MinI)

- PC27 = SpeedUp Time

Inverter

100.00 %

MinI

SP + OFSI SP + OFSI + DI

Pressure

Based on the measured value from the suction probe, the output of the regulator will assume different values. If the value measures with the probe is less than or equal to the SP + OFSI value, the output of the regulator assumes the value 0. If the value measured with the probe is between the SP + OFSI value and the SP + OFSI + DI, the output of the regulator will assume a value which is proportional to the value of the suction probe. If the suction probe assumes a value which is higher than or equal to the SP + OFSI + DI value, the output of the inverter will assume maximum value. If the MinI parameter has been set, at every turn-on the inverter will maintain that value as a starting value. If the parameter for the speedUp time has been set, at every breakaway point the inverter will assume maximum value for the seconds described by this parameter. The range of values that the inverter output can assume lies between 0 and 100 percentage points, with two decimal numbers.

6.3.4 Neutral zone adjustment with inverter

This check adds an inverter type adjustment to a normal neutral zone adjustment; in order to do this, it is necessary to set some parameters relative to the inverter device that will be used, besides enabling its use. The parameters relative to the first circuit are the following:

- SPC1 = Setpoint compressors (SP)

- PC14 = Type of adjustment = 1

- PG12 = Activation inverter

- PC26 = Minimum value of inverter (MinI)

- PC27 = SpeedUp Time

- PC28 = Time or ramp of inverter (TI)

The adjustment varies according to the zone (neutral, turn-on or shutdown) in which the regulator is found. In the neutral zone, the inverter is not subjected to any variation and no compressors are turned on or off. In the turn-on zone:

- as soon as it is required, the inverter is activated.

- the value of the inverter changes according to the time TI set by the parameter. This represents the time

needed by the ramp of the inverter to go from the minimum value to the maximum value.

- when the inverter reaches the required maximum value, another step is required of the compressors.

- once the request is accomplished the value of the inverter is restored to the minimum value (MinI if

different from zero)

- If the turn-on zone remains, the cycle restarts.

If the turn-on request remains, all the compressors are turned on one by one, and at the end, the value of the inverter is brought to the maximum value. In the shutdown zone:

- as soon as it is required, the output of the inverter is brought to the minimum value, according to the TI.

- when the inverter reaches the minimum value, the compressors are required to shut down another step.

- once the request for a shutdown is completed, if the shutdown zone remains, the value of the inverter is

restored to the maximum value and the cycle restarts.

out inverter

If the request for a shutdown remains, all the compressors are shut down, one by one, and at the end the value of the inverter is brought to zero.

If the MinI parameter has been set, at every turn-on the inverter will keep that value as the starting value. If the parameter for the speedUp time has been set, at every breakaway the inverter will assume the maximum value for the seconds described by this parameter.

6.4 Management of the compressors

The program is able to manage up to a maximum of 4 compressors of equal power, divided into circuits and up to 2 throttlings for each compressor. To each compressor, certain digital inputs for safety measures and digital outputs for turn-on/shutdown and for potential throttlings may be associated.

The main configuration parameters are the following:

- PG01 = Circuit number

- PG11 = Number of compressors circuit 1

- PG15 = Number of compressors circuit 2

- PG04 = Number of throttlings

- PG05 = Activation of compressor safety measures

The management of the compressors occurs through a setPoint and a differential that can be set by a parameter and the reading of a pressure on the suction probe. Turn-on/shutdown is ensured by a thermo-adjustment and by certain timings that protect the various breakaways.

6.4.1 Rotation of the compressors

The rotation of the compressors is a procedure that makes it possible to balance as much as possible the number of functioning hours and the number of breakaways for each compressor. The rotation only refers to the compressors and not to the single throttlings, it does not involve potential compressors that have been subject to

Page 52

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

an alarm or that are in manual function mode and it is able to dynamically turn on other compressors if one or more are subject to a state of alarm. Through the PC01 parameter, the program is able to manage 4 types of rotation: FIFO, LIFO, FIFO + hours, LIFO + hours.

1) FIFO

Follows the logic “First In First Out”, or in other words, the first compressor that turns on will then be the first that must shut off. This logic could initially lead to a large difference in the hours of operation among the various compressors, but after an initial phase, the hours should approximately be equal. Example. Turn-on : C1 . C2 . C3 . C4 Shutdown: C1 . C2 . C3 . C4

This type of rotation has a particular feature in the case where all the compressors configured in the system do not turn on; in fact, if, for example, the first compressor turns on and then shuts off, the next compressor to turn on will be the second. The last compressor that shut off is memorized and the next one in sequence is turned on so that the same compressor is not always used and thus all the configured parts are taken advantage of in the best possible way.

Example with 4 compressors Turn-on : C1 . C2 . Shutdown: C1 . C2 . Turn-on : C3. C4. Shutdown: C3. C4. Turn-on : C1 . C2 . C3. C4. Shutdown: C1 . C2 . C3. C4.

2) LIFO

Follows the logic “Last In First Out”, or in other words, the last compressor turned on will be the first to be turned off. Example. Turn-on : C1 . C2 . C3 . C4 Shutdown: C4 . C3 . C2 . C1 The turn-on order will always begin with the C1 compressor.

3) FIFO + hours of operation

This rotation promotes the comparison of the hours of operation of the various compressors. During turn-on, the compressor with the least number of hours of operation will be favored, while during shutdown, the compressor with the greatest number of hours will be favored. In the case where a choice must be made among compressors that have the same number of hours, a FIFO rotation takes effect, in such a way as to in any case guarantee a rotation, even when there are the same number of hours of operation. Example. 1 Turn-on : C1(3 hours) . C2(3 hours) . C3(3 hours) . C4(3 hours) Shutdown: C1(3 hours) . C2(3 hours) . C3(3 hours) . C4(3 hours) Example. 2 Turn-on : C1(1 hour) . C2(3 hours) . C3(3 hours) . C4(5 hours) Shutdown: C4(5 hours) . C2(3 hours) . C3(3 hours) . C1(1 hour)

4) LIFO + hours of operation

6.4.2 Management of throttlings

The program is capable of managing up to 4 throttled compressors. Throttling a compressor means distributing its total load over various steps, improving its function and decreasing the number of breakaways so as to ensure that the machine lasts longer.

Number of throttlings

It is possible to choose, using the parameter PG04, one or two throttlings of equal power for each compressor. Each compressor will have the same number of throttlings available. The configurations possible for the number of throttlings per compressor are clearly limited by the number of available digital outputs.

Throttling logic

If compressors subjected to throttling are being used, it is possible, through the use of the PC03 parameter, to choose the logic of operation of the outputs dedicated to throttling:

- If set to zero, the outputs will be normally excited (closed) and will be opened to request more

power: NC logic Copeland.

- If set to one, the outputs will normally not be excited (open) and will be closed to request more

power: NO logic Feeders.

Turn-on/Shutdown Mode

In the case where compressors subjected to throttling are used, the PC02 parameter makes it possible to set the turn-on/shutdown mode of the throttlings. If set to zero:

Turn-on: CppCppCpp. The program favors the complete turn-on of the single compressor before passing to the next one. Shutdown: ppCppCppC. The program favors the compete shutdown of the single compressor before passing to the next one.

If set to one:

Turn-on: CCCpppppp. The program favors first the turn-on of all compressors and only following this, will it act on the throttlings. Shutdown: ppppppCCC. The program favors first the shutdown of all the throttlings and only at the end will it shut down all the compressors.

Note. In this last case, the logic in turn-on and shutdown of the single throttlings follows this logic (example with 3 compressors): Turn-on compressors : C1 . C2 . C3 Turn-on throttlings : p1C1 . p1C2 .p1C3 / p2C1 . p2C2 . p2C3 Shutdown throttlings : p2C3 . p2C2 . p2C1 / p1C3 . p1C2 . p1C1

6.4.3 Protection timings

Below, there is a list of all the timings related to the management of the compressors.

Neutral Zone Timings

These parameters serve to adjust the time intervals of the requests for turn-on and shutdown of the various steps supplied by the compressors:

Minimum time request for turn-ons Maximum time request for turn-ons Minimum time request for shutdowns Maximum time request for shutdowns

For these parameters, refer to the description in paragraph 2.2.2.

Protection timings

These times serve to protect the mechanical instruments from the various breakaways to which they are subjected.

PC04 – Minimum time turn-on of compressors. Once activated, the compressor will stay on for this amount of time before it can be shut off.

PC05 – Minimum time shutdown of compressors. Minimum amount of time that must pass after the last shutdown before the compressor can be turned on again.

PC06 – Minimum time between turn-ons of same compressor. Establishes the minimum amount of time that must pass between two turn-ons of the same compressor.

PC07 – Minimum time between turn-ons of different compressors. Establishes the minimum amount of time that must pass between the turn-on of one compressor and the next. If enabled, this serves to avoid simultaneous breakaways.

PC08 – Minimum time between shutdowns of different compressors. Establishes the minimum amount of time that must pass between the shutdown of one compressor and the next.

PC09 – Minimum time turn-on of throttlings. Establishes the minimum amount of turn-on time between the throttlings of a compressor.

PC10 – Minimum time shutdown of throttlings. Establishes the minimum amount of shutdown time between the throttlings of a compressor.

PC27 (PC47) – speedUp time. If adjustment with inverter is set, this parameter, if different from zero, allows the inverter output to remain at maximum level (100.00%) at each request for the turn-on of a new step.

6.4.4 Safety inputs

The program foresees the management of 1 safety “thermal compressor” input for each compressor. For this input, it is possible to set the type of reset (automatic or manual) and the intervention delay, through the use of parameters. To enable the alarms related to these safety measures, besides setting the parameters mentioned above as needed, it is also necessary to set the positions in which the digital inputs will be connected relative to the various types of alarm from the menu Constructor -> Hardware. In the case where there is no wish to set the alarm, all that is needed is to set the parameter mentioned above to the value of 0.

6.4.5 Inverter configuration

For each inverter used in the plant must be selected also the related digital output position for the command/consent at the inverter start; For the configuration the same parameters of the compressor digital outputs are used, parameters HC01, HC02, HC03, HC04. The inverter is virtually the first compressor of each circuit; this means that, depending of the compressors and circuits number, the right parameter must be set, by following below logic:

⋅ Signle Circuit: The inverter (if enabled) is virtually the compressor 1; it is neccessary to configure the

parameter of the first compressor, this means that parameter HC01 must be always configured.

⋅ Two circuits: The inverter of circuit 1 (if enabled) is virtually the compressor 1 (this means that

parameter HC01 must be configured), and the circuit 2 inverter (if enabled) is virtually the first compressor after the circuit 1 compressors.

Note. The PH20 parameter modifies the logic for the inverter consent (managed by relay or by PWM).

Configuration examples.

1) N°1 Circuit (PG01=1), n°2 Compressors (PG11=2), Inverter enabled (PG12=1). A correct configuration is:

HC01 = 1 -> Digital output for the inverter consent

HC02 = 2 -> Digital output for the hermetic compressor command HC31 = 1 -> Analog output for the inverter command

2) N°2 Circuits (PG01=2), n°2 Compressors for each circuit (PG11=2, PG15=2), Inverters enabled (PG12=1, PG16=1). A correct configuration is:

HC01 = 1 -> Digital output for the circuit 1 inverter consent

HC02 = 2 -> Digital output for the circuit 1 hermetic compressor command

HC03 = 3 -> Digital output for the circuit 2 inverter consent

HC04 = 4 -> Digital output for the circuit 2 hermetic compressor command HC31 = 1 -> Analog output for the circuit 1 inverter command HC32 = 2 -> Analog output for the circuit 2 inverter command

3) N°2 Circuits (PG01=2), n°1 Circuit 1 compressor, n°2 Circuit 2 compressors (PG11=1, PG15=3), Only circuit 2 inverter enabled (PG12=0, PG16=1). A correct configuration is:

HC01 = 1 -> Digital output for the circuit 1 first hermetic compressor command

HC02 = 2 -> Digital output for the circuit 2 inverter consent

HC03 = 3 -> Digital output for the circuit 2 first hermetic compressor command HC04 = 4 -> Digital output for the circuit 2 second hermetic compressor command HC31 = 1 -> Analog output dor the circuit 1 inverter command HC32 = 2 -> Analog output dor the circuit 2 inverter command

4) N°2 Circuits (PG01=2), n°1 Circuit 1 compressor, n°3 Circuit 2 compressors (PG11=1, PG15=3), Inverters enabled (PG12=1, PG16=1). A correct configuration is:

HC01 = 1 -> Digital output for the circuit 1 inverter consent HC02 = 2 -> Digital output for the circuit 2 inverter consent

Page 56

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

Inverter consent with PWM

In some applications it can be necessary to command the consent of the inverters with a PWM output configuring 0% or 100%. To use this option is necessary to operate with the same logic used in the previous examples on the parameters HC0x, configuring the values according to this rule:

HC01 = 13 -> Defines that the PWM output on the controller is used for the consent

of the compressor with inverter of circuit 1

HC0x = 14 -> Defines that the PWM output on the controller is used for the consent

of the compressor with inverter or circuit 2

Note. Configurino the value 13 or 14, is used the related PWM, this means that the possibile parameters HC31, HC32, HF31, HF32 should not be configured as PWM.

6.4.6 Compressors with different power

The management of compressors with different power could be useful to be able to more precisely regulate the establishment of the final value compared to the configured setpoint. To use this management, the related parameter, enable compressors of different power (PG03), must be enabled and the parameters that represent the power of each compressor whose utilization is desired in the system must be set. The software calculates the maximum power able to be expressed from the single powers of the compressors; according to the requirements of the regulators it calculates the best combination of compressors to deliver the requested power. For a better regulation, the internal resolution of the step is multiplied by three; in this way, by using compressors with different power, there are more combinations that can match the exact power requested by the regulator. At each variation of the request, the combination of compressors is recalculated in such a way as to produce a power to be delivered that is equal or greater than that requested. Compressors manually disabled, in alarm and under protections will not take part to the computation.

Note. Enabling this function, compressors subjected to throttling or compressors with inverters are not able to be used.

Sideband Adjustment

Based on the parameters of adjustment (paragraph 2.3.1), the application will calculate the power necessary to return the pressure/temperature detected in the proximity of the desired setpoint. The required power will be calculated based on the proportional regulator or proportional + integral, while the power supplied will be given by the combination of powers of the compressors that more closely exceeds what is required.

Neutral Zone Adjustment

Based on the zone where the regulator is found, a new sequence of compressors to activate is calculated, and more precisely:

- In the neutral zone: the combination remains unchanged.

- In the turn-on zone: the combination of compressors is recalculated in order to guarantee a power that is

greater than that supplied by the previous combination.

- In the shutdown zone: the combination of compressors is recalculated in order to guarantee a power that

is inferior to that supplied by the previous combination.

The recalculation of the combinations occurs based on the timings of the neutral zone: refer to paragraph 2.3.2.

Example

Consider 3 compressors of different power and a sideband adjustment of a proportional type, with these parameters:

Page 57

Applying the formula of calculation for the required power, these values are obtained. Below the setpoint, the power delivered is null, above the setpoint, the power delivered is at the maximum.

6.4.7 Compensation for load losses on the suction line

In certain systems, it may be necessary to decrease the suction setpoint with the increase in the yield of coolant, to compensate for the losses of pressure along the suction line. Users, which should operate at a constant evaporation pressure, will in essence find themselves working at higher pressures when there is a higher need for cold temperatures, and vice versa. This means that, in order to guarantee the production of coldness at the desired temperature even with loads in the proximity of the nominal values, one must work with a setpoint that is appreciably lower even at partial loads, when it wouldn’t be necessary. The compensation works by introducing an offset that is able to be set, which lowers the setpoint gradually at each call of cold steps; it appears evident that this function acts with the intention of increasing the efficiency of the system, making it possible to choose a higher setpoint for lower loads. Through the PH35 parameter this function is enabled, which leads to a lowering of the setpoint by a factor of compensation for each step inserted and to an increase in the setpoint by the same value for each step released. This function is able to be activated only with adjustment in the neutral zone.

6.4.8 Throttling of the refrigerating power at high pressures

To prevent the intervention of the high condensation pressure regulator and the resultant blockage in cold production, it is possible to reduce the refrigerating power and subsequently the power of exchange at the condenser, lowering in this way the condensation pressure. This reduction is possible only with circuits that are subjected to throttling (with at least two compressors or with a compressor equipped with throttling devices). The parameters related to the first circuit for this function are the following:

- PC70 = Enables throttling at high pressures

- PC71 = Setpoint limit for pressure regulator check of condensation

- PC74 = Differential for pressure regulator check

- PC75 = Minimum maintenance time for pressure regulator throttling

- PC76 = Percentage value of throttling

6.5 Adjustment of condensation

The management of condensation foresees control through discharge pressure fans: according to the type of control (sideband control or neutral zone control) and according to the use or disuse of the inverter for a finer adjustment, four types of adjustment are considered.

6.5.1 Sideband adjustment

Sideband control uses the characteristics of the PI regulators (proportional and integral) or the P regulators (proportional) to establish when to plug in or unplug the fans used, in order to regulate the turn-on or the shutdown of the various devices inside the differential band. The parameters relative to the first circuit are the following:

- SPF1 = Setpoint fans (SP)

- PF14 = Type of adjustment = 0

- PF16 = Integral time (TI)

- PF17 = Lateral band (BP)

- PG41 = Number of fans

The number of fans supplies the Maximum Number of Steps with which the proportional band is divided. The purpose of the PI adjustment is to obtain a null error in this scheme.

The above figure shows the behavior of the band adjustment (SP, SP +BP). Based on the value of the discharge pressure, the adjustment adds or subtracts the number of fans to be requested. In this adjustment, the band is found entirely on the setPoint.

It is possible to choose if the control will refer to the PI adjustment or only to the P adjustment, by setting the parameter for the integral action, which is the integration time (Ti). Specifically, if this parameter is set to the value of zero, the adjustment is only proportional, otherwise, it also becomes integral. The Ti corresponds to the time needed by the integral action to become equal to the proportional action, in the hypothesis of a constant error: the speed of such action is proportionally linked to the value of the integration time. The default parameter is 600 seconds, so the adjustment uses the proportional + integral characteristic.

As for the compressors, even with the sideband adjustment of the fans it is possible to improve the behavior of the adjustment band, using the parameter PF78 Sideband steps overlapping factor.

6.5.2 Neutral zone adjustment

This adjustment implies the definition of a neutral zone in which no decision of activation or deactivation is made, which means that there will be no requests for breakaways of any devices.

The parameters relative to the first circuit are the following:

- SFC1 = Setpoint fans (SP)

- PF14 = Type of adjustment = 1

- PF18 = Neutral Zone (NZ)

- PF19 = Differential outside the neutral zone (diff)

- PF20 = Time of turn-on/shutdown (ToutNZ)

Outside the neutral zone, the requests for turn-on or shutdown of the configured fans will follow this logic:

- Turn-on: when the discharge pressure exceeds the threshold value setPoint + Neutral Zone

- Shutdown: when the pressure becomes less than the setPoint

In this adjustment, the neutral zone is found entirely to the right of the setPoint.

As you can see from the figure, the adjustment implies the setting of two times, within which, depending on the zone, the requests for turn-on and shutdown of the various steps must be managed to ensure the establishment of proper time intervals. If we are in the shutdown zone, every shutdown request must wait for ToutNZ seconds before it is fulfilled. Instead, in the case of the turn-on zone, every turn-on request will have to wait for ToutNZ seconds before it is fulfilled.

6.5.3 Sideband adjustment with inverter

This check adds an inverter adjustment to the normal sideband adjustment; in order to do this, it is necessary to set some parameters relative to the inverter device that will be used, besides activating its use. The parameters relative to the first circuit are the following:

- SPF1 = Setpoint fans (SP)

- PF14 = Type of adjustment = 0

- PG42 = Inverter activation

- PF24 = Differential inverter (DI)

- PF25 = Inverter offset with respect to the suction setPoint (OFSI)

- PF26 = Minimum value of inverter (MinI)

- PF27 = Time of speedUp

Inverter

100.00 %

MinI

SP + OFSI SP + OFSI + DI

Pressure

Based on the value measured by the discharge probe, the output of the regulator will assume different values. If the value measured by the probe is less than or equal to the value SP + OFSI, the output of the regulator will assume the value of 0. If the value measured by the probe is between the value SP + OFSI and the value SP + OFSI + DI, the output of the regulator will assume a value that is proportional to the value of the discharge probe. If the discharge probe assumes a value that is higher than or equal to the value SP + OFSI + DI, the output of the inverter will assume maximum value. If the MinI parameter has been set, at every turn-on, the inverter will keep that value as the starting value. If the parameter for the speedUp time has been set, at every breakaway, the inverter will assume the maximum value for the seconds described by this parameter. The range of the values that the inverter output may assume lies between 0 and 100 percentage points, with two decimal numbers. The use of this adjustment on the main fan is not linked to the adjustment of the other fans, since the two functions are independent.

6.5.4 Neutral zone adjustment with inverter

This check adds an inverter adjustment to the normal neutral zone adjustment; in order to do this, it is necessary to set some parameters relative to the inverter device that will be used, besides activating its use. The parameters relative to the first circuit are the following:

31 SPF1 = Setpoint fans (SP) 32 PF14 = Type of adjustment = 1 33 PG42 = Inverter activation 34 PF26 = Minimum value of inverter (MinI) 35 PF27 = Time of speedUp 36 PF28 = Time or ramp of inverter (TI)

The adjustment varies according to the zone (neutral, turn-on or shutdown) in which the regulator is found. In the neutral zone, the inverter does not go through any change and no fans are turned on or off. In the turn-on zone:

9 as soon as it is requested, the inverter is activated. 10 the value of the inverter changes according to the time TI set by the parameter. This represents the time

needed by the ramp of the inverter to go from the minimum value to the maximum value.

11 when the inverter reaches the maximum value, the other fans are requested one by one.

If the turn-on zone remains, all the fans are turned on, one by one, and the value of the inverter stays at the maximum. In the shutdown zone:

12 as soon as it is requested, the output of the inverter is brought to the minimum value, depending on the

TI.

13 when the inverter reaches the minimum value, the fans are required to turn off, one by one.

If the request for shutdown remains, all the fans are turned off, one by one, and the value of the inverter stays at zero. If the MinI parameter has been set, at every turn-on, the inverter will keep that value as the starting value.

Page 62

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

If the parameter for the speedUp time has been set, at every breakaway, the inverter will assume the maximum value for the seconds described by this parameter.

6.5.5 Single condensation (only bi-circuit)

Single condensation makes it possible to perform the ventilation process through only one circuit. For this input, it is possible to set the type of resetting (automatic or manual) through the parameters. By setting the parameter PG30 single condensation activation, the number of circuits for the fans is forced to one, while the number of circuits chosen for the compressors remains unchanged. The single condensation will deactivate all the characteristics (alarms, fans, inverter,…) that are relative to the second circuit for the management of the fans.

6.6 Management of the fans

The program is able to manage up to a maximum of 4 fans. To each fan, a digital safety input and a digital turnon/shutdown output may be associated.

The main configuration parameters are the following:

- PG01 = Number of circuits

- PG41 = Number of fans circuit 1

- PG45 = Number of fans circuit 2

- PG32 = Activation fan safety

The number of fans that are directly controlled by the digital output is further limited by the number of compressors (throttled or not), which means by the number of digital outputs remaining after the configuration of the compressors. It is possible to use a single condensation, which is a condensation only on one circuit, by setting the relative PG30 parameter. The management of the fans occurs through a setPoint and a differential that can be set by a parameter and the reading of a pressure on the discharge probe. Turn-on/shutdown is ensured by a thermo-adjustment and by several timings that protect the various breakaways.

6.6.1 Rotation of the fans

The rotation of the fans is a procedure that makes it possible to balance as much as possible the number of hours of operation and of breakaways for every device. The rotation does not involve any fans in a state of alarm or in manual mode and it makes it possible to dynamically turn on others if one or more of them go into a state of alarm. Using the PF01 parameter, the program is able to manage 4 types of rotation: FIFO, LIFO, FIFO + hours, LIFO + hours.

1) FIFO

It follows the “First In First Out” logic, which means the first fan turned on will be the first one that will have to shut down. This logic could initially lead to a large difference in the hours of operation among the various fans, but after an initial phase, these will almost be the same. Example. Turn-on : F1 . F2 . F3 . F4 Shutdown: F1 . F2 . F3 . F4

This type of rotation has a peculiarity in the case where all the fans configured in the system do not turn-on; in fact, if, for instance, the first fan is turned on and then it shuts down, the next fan to be turned on will be the second. The last fan turned off is memorized in order to turn on the next fan in the sequence, so that the same fan is not used, taking advantage in this way of all the configured condenser items.

Page 63

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

Example with 4 fans. Turn-on : F1 . F2 . Shutdown: F1 . F2 . Turn-on : F3. F4. Shutdown: F3. F4. Turn-on : F1 . F2 . F3. F4. Shutdown: F1 . F2 . F3. F4.

2) LIFO

It follows the “Last In First Out” logic, which means that the last fan turned on will be the first one to be shut down. Example. Turn-on : F1 . F2 . F3 . F4 Shutdown: F4 . F3 . F2 . F1 The turn-on order will always start from the C1 compressor.

3) FIFO + hours of operation

This rotation favors the confrontation of the hours of operation of the various fans. During turn-on, the one with the fewest number of hours of operation will be favored, while during shutdown, the one with the highest number of hours will be favored. If it is necessary to choose among fans with the same number of hours, a FIFO rotation is activated so that a rotation is ensured even in the case of similar hours of operation. Example. 1 Turn-on : F1(3 hours) . F2(3 hours) . F3(3 hours) . F4(3 hours) Shutdown: F1(3 hours) . F2(3 hours) . F3(3 hours) . F4(3 hours)

Example. 2 Turn-on : F1(1 hours) . F2(3 hours) . F3(3 hours) . F4(5 hours) Shutdown: F4(5 hours) . F2(3 hours) . F3(3 hours) . F1(1 hour)

4) LIFO + working hours

This rotation favors the confrontation of the hours of operation of the various fans. During the turn-on phase, the one with the fewer number of hours of operation will be favored, while during shutdown, the one with the highest number of hours will be favored. If it is necessary to choose among fans with the same number of hours, a LIFO rotation is activated, to ensure a rotation even in the case of the same number of hours of operation. Example. 1 Turn-on : F1(3 hours) . F2(3 hours) . F3(3 hours) . F4(3 hours) Shutdown: F4(3 hours) . F3(3 hours) . F2(3 hours) . F1(3 hours)

Example. 2 Turn-on : F1(1 hour) . F2(3 hours) . F3(3 hours) . F4(5 hours) Shutdown: F4(5 hours) . F3(3 hours) . F2(3 hours) . F1(1 hours)

6.6.2 Fan timings

A list of all the timings relative to the management of the compressors is indicated below

Neutral Zone Timings

These parameters are useful to the organize the turn-on and shutdown request for the several condensation devices so as to establish certain time intervals.

Minimum turn-on request time. Minimum shutdown request time.

For these parameters, refer to the description made in paragraph 2.4.2.

Page 64

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL

Protection timings

These times serve to protect the fans from the various breakaways to which they are subjected.

PF07 – Minimum time between turn-ons of different fans. Establishes the minimum amount of time that must pass between the turn-on of one fan and the next. If it is set, it makes it possible to avoid simultaneous breakaways.

PF08 – Minimum time between shutdowns of different fans. Establishes the minimum amount of time that must pass between the shutdown of one fan and the next. If it is set, it makes it possible to avoid simultaneous breakaways. PF27, PF47 – speedUp time. If inverter adjustment is set, this parameter, if different from zero, makes it possible for the inverter output to remain at the maximum value (100.00 %), each time that the turn-on of a new fan is required.

6.6.3 Safety inputs

The program foresees the management of a single “thermal fan” safety measure for each of the fans configured in the application. The activation of this characteristic is managed by the parameter PG32 enable fan safety. To enable the “thermal fan” alarms, besides setting the appropriate parameter, the positions in which the digital inputs related to the various fans selected will be connected must also be set using the menu Constructor -> Hardware. If there is no wish to set the alarm, it is sufficient to set the parameter mentioned above to the value of 0.

6.6.4 Inverter configuration

For each inverter used in the plant must be selected also the related digital output position for the command/consent at the inverter start; For the configuration the same parameters of the fans digital outputs are used, parameters HF01, HF02, HF03, HF04. The inverter is virtually the first fan of each circuit; this means that, depending of the fans and circuits number, the right parameter must be set, by following below logic:

⋅ Signle Circuit: The inverter (if enabled) is virtually the fan 1; it is neccessary to configure the parameter

of the first fan, this means that parameter HF01 must be always configured.

⋅ Two circuits: The inverter of circuit 1 (if enabled) is virtually the fan 1 (this means that parameter HF01

must be configured), and the circuit 2 inverter (if enabled) is virtually the first fan after the circuit 1 fans.

Inverter consent with PWM

HC01 = 13 -> Defines that the PWM output on the controller is used for the consent

of the fan with inverter circuit 1

HC0x = 14 -> Defines that the PWM output on the controller is used for the consent

of the fan with inverter circuit 2

Note. Configuring the value 13 or 14, the related PWM is used, this means that the possibile parameters HC31, HC32, HF31, HF32 should not be configured as PWM.

The choice and the configuration of the fan inverters parameters is the same for the compressors, but the parameters PH21, HF01, HF02, HF03 and HF04 are used (look at paragraph 6.4.5)

6.7 Various management issues

6.7.1 Digital input or supervisor setpoint variation

It is sometimes important to reduce the energy consumption of the compressors or the noise level of the fans (for example at night). The program foresees, both for compressors and fans, the possibility of managing a parameter, PUC1 (PUC2) offset secondary setPoint compressors and PUF1 (PUF2) offset secondary setPoint fans, which, based on the state of a digital input (different for compressors and fans), sums an offset to the main setpoint in order to allow it to vary. It is possible to set the logic for the digital input by acting on the parameter PH19 Logic Other DI (the same parameter for the logic of the digital input on/off). To set this function, the parameter PH25 enable secondary digital input setpoint must be activated and the position in which the digital input related to the compressors and the one related to the fans will be connected must be set. If this value is not set, the function will remain disabled. Similarly, activating the parameter PH26 enable secondary supervisor setpoint, it is possible to use the relative offsets both for the compressors and for the fans.

6.7.2 Manual function

The program makes it possible to set a manual function for compressors and fans. In this state, the devices do not participate either in the rotations or in the calculation of thermo-adjustment, though they are still sensitive to possible alarms. The manual functioning of the devices is useful when functional tests must be run on the machine to test integrity and proper functioning.

Compressors

The manual functioning or lack thereof of the compressors is guaranteed by the parameter PM1x enable compressor:

- If it is set to the Auto value, it defines the normal functioning of the device

- If it is set to the Manu value, it disables the compressor and leads to manual functioning.

A compressor that is functioning manually does not participate in the adjustments and may be forced into the number of steps that it is able to supply by acting on the property PM2x compressor forcing (present in the menu Maintenance -> Forcing of Compressors). The number of steps that a compressor functioning manually can supply is limited to the number of throttlings that have been set in the configuration of the machine. As was stated previously, the compressor is in any case still sensitive to alarms and related consequences. To restore the compressor to normal use, the parameter PM1x enable compressor must be reset to the Auto value, otherwise the compressor in question will continue to function manually and will not heed the turn-on and/or shutdown requests calculated by the adjustment set.

Fans

The manual functioning or lack thereof of the fans is guaranteed by the parameter PM5x enable fan:

- If it is set to the Auto value, it defines the normal functioning of the device

- If it is set to the Manu value, it disables the fan and leads to manual functioning.

A fan that is functioning manually does not participate in the adjustments and may be forced to turn on/shut down by acting on the property PM6x fan forcing (present in the menu Maintenance -> Forcing of Fans). As was stated previously, the fan is in any case still sensitive to alarms and related consequences. To restore the fan to normal use, the parameter PM5x enable fan must be reset to the Auto value, otherwise the fan in question will continue to function manually and will not heed the turn-on and/or shutdown requests calculated by the adjustment set.

Inverters

When it is an inverter that must be manually forced, the procedure is slightly different. Recall that the inverter is virtually the first compressor of each circuit, therefore before being able to correctly perform the procedure, the correct compressor must be changed to manual, in other words:

- 1 Circuit: The inverter (if enabled) is compressor 1; in order to switch the inverter to manual

functioning, it is necessary to switch the first compressor to manual functioning.

- 2 Circuits: The inverter of circuit 1 (if enabled) is compressor 1 and the inverter of circuit 2 (if

enabled) is the first compressor following the compressors of circuit 1; to switch the inverters to manual functioning, it is necessary to switch these compressors to manual functioning.

Once the manual functions have been correctly set, it is possible to force the inverters using the specific parameter: PM37 (PM38) compressor inverter forcing.

In order to correctly configure this characteristic, it is sufficient to enable at least one compressor/fan inverter; depending on the type enabled, the other type will be automatically excluded by the analogue outputs.

The management and the forcing procedure of the fan inverters is the same as that for the compressor inverters.

6.7.3 Floating condensation management

Makes it possible to modify the working setpoint of the fans depending on the external temperature. To enable this function, the following parameters must be set in the menu Installer -> Various:

- enable external temperature probe (PH24)

- enable floating condensation (PF71)

- delta Condensation temperature (PF72): offset of condensation temperature (linked to the type of

condenser module used)

- inferior limit Condensation temperature (PF73): minimum value of the condensation temperature

(owing to the need to guarantee a minimum temperature of the lubricating oil)

- upper limit Condensation temperature (PF74): maximum value of the condensation value, beyond

which the fans no longer modulate and therefore reach the maximum.

The new setpoint will be given by the external temperature summed to the parameter delta temperature. The values of this new set, converted to pressure, are in any case limited by the variation range of the condensation setpoint.

Note. By enabling this function, the condensation setpoint parameters of the single circuits no longer have any effect on the adjustment of the condensation; in fact, the setpoint used will be a function of delta T and of the external temperature.

6.7.4 Temperature probes

The application is capable of managing a maximum of two auxiliary temperature probes: environment probe and external probe. To make use of these two temperature transducers, their activation parameters, enable environment temperature probe and enable external temperature probe, must be set. Each of the two probes is associated with a probe alarm, which is set off when the probe is disconnected or broken; the activation of this alarm is associated with the parameter of probe activation. By activating the probes, the related alarm is also activated. In the case of no activation, the screens will display the value of 0.

6.7.5 Restoration of default parameters

Through the “Parameter restoration” procedure, it is possible to restore all the parameters of the system to the default values. This function is simple to activate by acting on the value of the appropriate parameter PH15 present in the Map menu, accessible only when the machine is turned off; setting it to “1”, the system will automatically see to the restoration of all parameters. Following this operation, it is necessary to unplug the machine and then plug it back in to avoid malfunctions.

6.7.6 Programming key

It is possible to save the value of all system parameters in the programming key and to then to copy this information to one or more compatible instruments. The saving or restoration process may be performed while the machine is on, connecting the key to the programming connector.

To save a particular parameter map in the key:

- access the Map menu and select “Stor” using the UP or DOWN buttons

- Push the SET (ENTER) button: the transfer of the parameters to the

key is highlighted by the blinking of the appropriate led

- Wait for the blinking to end; if the led is green, the operation

terminated correctly, otherwise the led is red

To copy a parameter map from the key to an instrument:

- access the Map menu and select “rESt” using the UP or DOWN

buttons

- Push the SET (ENTER) button: the transfer of the parameters from the

key to the instrument is highlighted by the blinking of the appropriate led

- Wait for the blinking to end: if the led is green, the operation terminated correctly, otherwise the led is red

Note: the key is able to save information relating to the product and its related version, in such a way as to allow for the transfer of parameter maps only between instruments that are compatible with each other.

7 DIAGNOSTICS

The application is able to manage a series of alarms related to system compressors, fans, circuits and functions. Depending on the various types of alarm, it is possible to configure their resetting (if manual or automatic), a possible delay in signal and certain actions to perform in specific circumstances. When one or more alarms are active, the alarm icon on the screens blinks. To visualize the various alarms, the menu “Alar” must be visualized from the main page using the ESC key and then ENTER must be pressed. To scroll through the various active alarms, it is necessary to again hit the ENTER key: the alarms will be shown in the order of importance, as they are listed in the table of alarms in paragraph 3.2. All the digital inputs related to the alarms are managed by the parameter Alarm Logic that takes on the following meaning:

- If set to “NO”, the inputs will be normally un-excited (open): N.O. logic

- If set to “NC”, the inputs will be normally excited (closed): N.C. logic

7.1 Manual and automatic alarms

As mentioned previously, there are two types of alarms, those that are reset manually and those that are reset automatically. With some alarms there is the possibility of setting the type of reset that most suits the needs of the user through a certain parameter (Alarm reset).

Manual alarms

In the case that a manual alarm presents itself:

- The alarm icon begins to blink

By hitting the ENTER key in the “Alar” menu, the code of the alarm that was first activated is displayed. Once the conditions that triggered the alarm are reversed, it is possible to manually reset the alarm. To do this:

- go to the page of the alarm to be reset

- hold down the ENTER key for about 2 seconds.

At this point, if there are no other alarms, the page indicating “none” will appear, the alarm icon will shut off and the machine will return to its normal functioning, or the code of the next alarm that has been activated will be displayed. The consequences deriving from an active manual alarm will remain valid until the user proceeds to cancel the alarm message.

Automatic alarms

In the case that an automatic alarm presents itself:

- The alarm icon begins to blink

Hitting the ENTER key in the “Alar” menu, the code of the alarm that was first activated is displayed. Once the conditions that triggered the alarm are reversed, the resetting and the cancellation of the alarm message are restored automatically without the user having to intervene. The consequences that derive from an active automatic alarm will remain valid until the causes that triggered the alarm are not reversed.

7.3 Alarm relays

The program has the possibility of managing up to three alarm relays. The activation of each of these devices is linked to the setting or lack thereof of the relative DO alarm position parameter. For activation, it is sufficient to set this value to a value that is different than zero; if the zero value is maintained, the alarm relay is not used. A list of the three relays, with their relative parameter, is presented below:

- A general alarm relay – Global DO alarm position

- An alarm relay for circuit 1 - DO alarm position circuit 1

- An alarm relay for circuit 2 - DO alarm position circuit 2

Through the relative parameter, it is possible to establish the polarity (NO or NC) of the various alarm outputs.

8 List of the MODBUS variables

It is possible to check the application through a supervisor, using the Modbus protocol. The communication occurs through a serial TTL interface, which is already integrated in the controller; we suggest using the external TTL/RS-485 interface (the interface is not supplied with the instrument). The various parameters that are exported by the application in the three versions of the application are reported below.
