Introduction

Application

The AK-CC 210B is dedicated for “plug-in cabinets” in supermarkets.

Principle

The AK-CC 210B controls the temperature in the cabinet based on the measurement from a single sensor – Sair. This sensor can be placed in the cold airﬂow after the evaporator or in the warm airﬂow before the evaporator, depending on the construction and usage of the cabinet.

Danfoss

Sair

A measurement of the defrost temperature can be obtained directly through the use of an S5 sensor or indirectly through the use of the Sair measurement.

Relays: the ﬁrst 3 relays are dedicated for Refrigeration, Defrost and Light, respectively. The usage of relay 4 is selected by the application setting, and can be Alarm, Fan, Rail heat, Condenser fan or Compressor 2.

The diﬀerent applications are described on page 6.

Advantages

• Many applications in the same unit

• The controller has integrated refrigeration-technical functions, so that it can replace a whole collection of thermostats and timers

• Buttons and seal imbedded in the front

• Alarm monitoring of condenser temperature with compressor stop protection.

• Sealed relays for use with R290 refrigerants

• Can control two compressors

• Easy to remount data communication

• Quick set-up

• Two temperature references

• Digital inputs for various functions

• Clock function with super cap back-up

Operation

Operation - Sensors

One thermostat sensor – Sair – can be connected to the controller, and the relevant application deﬁnes the placement. It can be placed in the air before the evaporator or in the airﬂow after the evaporator. The latter is mainly used where there is a risk of too low temperature at the products.

Sair

Defrost sensor

The best signal concerning the evaporator’s temperature is obtained from a defrost sensor mounted directly on the evaporator. Here the signal may be used by the defrost function, so that the shortest and most energy-saving defrost can take place.

If a defrost sensor is not required, defrost can be stopped based on time, or Sair can be selected.

Condenser temperature sensor

A condenser temperature sensor – Sc – can be used for monitoring the temperature on the condenser. Depending on settings, alarms can be generated and other actions, including safety stop of compressor, can be initiated based on this temperature.

Condenser temperature alarms and actions

An alarm warning can be activated when the temperature gets above a set Condenser Alarm limit and a critical alarm can be activated at a higher Condenser Block Alarm limit. At this critical level, diﬀerent actions can be initiated e.g. turning oﬀ the light in the cabinet, turning oﬀ the compressor, or both. The wanted action is deﬁned by parameter "P92".

Compressors can be permanently stopped if a deﬁned number of critical alarms occur within a deﬁned time period. If the number of events exceeds the setting in parameter "P94" within a period deﬁned in "P93", the last event will always include a compressor stop, together with other actions deﬁned in "P92". This state requires a manual reset before the compressor can start again.

Control of two compressors

This control is used for controlling two compressors of the same size. The principle for control is that one of the compressors connects at ½ the diﬀerential of the thermostat, and the other at the full diﬀerential. When the thermostat cuts in, the compressor with the fewest operating hours is started. The other compressor will only start after a set time delay, so that the load will be divided between them. The time delay has a higher priority than the temperature. When the air temperature has dropped by half the diﬀerential, one of the compressors will stop, while the other will continue working and not stop until the required temperature is achieved. The compressors used must be of a type that is capable of starting up against a high pressure.

Change of temperature reference

In an impulse appliance, for example, used for various product groups the temperature reference is changed easily with a contact signal on a digital input. The signal changes the normal thermostat setpoint by a predeﬁned value. At the same time the high and low alarm limits will be displaced with the same value.

Night setback

The thermostat reference can be displayed with an oﬀset at night. The alarm limit value will be changed with the same value as the night oﬀset. The change will only be applied for positive night oﬀset.

Digital inputs

There are two digital inputs, both of which can be used for the following functions:

- Case cleaning

- Door contact function with alarm

- Starting a defrost

- Coordinated defrost (DO2 only)

- Night setback

- Change-over between two temperature reference

- Report state of digital input via data communication

Case cleaning function

This function makes it easy to steer the refrigeration appliance through a cleaning phase. Via three pushes on a switch you change from one phase to the next phase. The ﬁrst push stops the refrigeration – the fans keep working. ”Later”: The next push stops the fans ”Still later”: The next push restarts refrigeration The diﬀerent situations can be followed on the display.

On the network, a cleaning alarm is transmitted to the system unit. This alarm can be ”logged” so that proof of the sequence of events is provided.

- + + °C

1 ÷ + Fan

2 ÷ ÷ Oﬀ

3 + + °C

Door contact function

In cold rooms and frost rooms the door switch can switch the light on and oﬀ, start and stop the refrigeration and give alarm if the door has remained open for too long.

Defrost

Depending on the application, you may choose between the following defrost methods: Natural: Here the fans are kept operating during defrost Electric: The heating element is activated Hot gas: The defrost output is used to control a solenoid that lets

the hot gas ﬂow through the evaporator. The compressor is kept running to generate hot gas.

Start of defrost

A defrost can be started in diﬀerent ways: Interval: Defrost is started at ﬁxed time intervals, e.g. every eighth hour Refrigeration time: Defrost is started at ﬁxed refrigeration time intervals. In other words, a low need for refrigeration will ”postpone” the coming defrost. Schedule: Here defrost can be started at ﬁxed times of the day and night. However, max. 6 times. Contact: Defrost is started with a contact signal on a digital input. Network: The signal for defrost is received from a system unit via the data communication. S5 temp In 1:1 systems the eﬃciency of the evaporator can be followed. Icing-up will start a defrost. Manual: An extra defrost can be activated from the controller’s lower-most button. (Though not for application 4).

All the mentioned methods can be used at random – if just one of them is activated a defrost will be started.

Coordinated defrost

There are two ways in which coordinated defrost can be arranged. Either with wire connections between the controllers or via data communication.

Max. 15

Wire connections

One of the controllers is deﬁned to be the controlling unit and a battery module may be ﬁtted in it so that the clock is ensured back-up. When a defrost is started, all the other controllers will follow suit and likewise start a defrost. After the defrost, the individual controllers will move into waiting position. When all are in waiting position there will be a change-over to refrigeration. (If just one in the group demands defrost, the others will follow suit).

Defrost via data communication

All controllers are ﬁtted with a data communication module, and via the override function from a gateway the defrost can be coordinated.

Defrost on demand

1. Based on refrigeration time

When the aggregate refrigeration time has passed a set time, a defrost will be started.

2. Based on temperature

The controller will constantly follow the temperature at S5. Between two defrosts, the S5 temperature will become lower the more the evaporator ices up (the compressor operates for a longer time and pulls the S5 temperature further down). When the temperature passes a set allowed variation, the defrost will be started. This function can only work in 1:1 systems.

Service request alarm

The controller will register the accumulated on-time in days, and a limit can be set to activate a “service request alarm” to indicate that inspection and cleaning of the fan and condenser is imminent. After doing so, the Runtime counter can be reset and a new period initiated.

User Guide | Controller for temperature control AK-CC 210B, SW 1.0x

Extra module

• The controller can afterwards be ﬁtted with an insertion module if the application requires it.

The controller has been prepared with plug, so the module

simply has to be pushed in.

- Battery module The module guarantees voltage to the controller if the supply

voltage should drop out for more than four hours. The clock function can thus be protected during a power failure.

- Data communication If you require operation from a PC, a data communication

module has to be placed in the controller.

• External display

If it is necessary to indicate the temperature on the front of

the refrigeration appliance, a display type EKA 163A can be mounted. The extra display will show the same information as the controller's display, but does not incorporate buttons for operation. If operation from the external display is needed a display type EKA 164A must be mounted.

Applications

AK-CC 210B is developed for refrigerated plug-in cabinets with one or 2 compressors. 3 sensors can be connected; Sair, S5 (Defrost termination), and Sc (Condenser temperature). The ﬁrst 3 relays are used for compressor on-oﬀ, defrost, and light while relay 4 is conﬁgurable via “o61” application setting. The relay can be conﬁgured for 5 diﬀerent applications:

1. Alarm relay

2. Evaporator fan control

3. Rail Heat Control

4. Condenser fan control

5. Second compressor control

DI1, and DI2 are ﬂexible Dry Contact inputs that can be conﬁgured for multiple functions via “o02” or “o37” (see settings page 12-13).

Survey of functions

Function Para-

Normal display

Normally the temperature value from the thermostat sensor Sair is displayed. Display air (u56)

Thermostat Thermostat control Setpoint

Regulation is based on the set value plus a displacement, if applicable. The value is set via a push on the centre button. The set value can be locked or limited to a range with the settings in r02 and r 03. The reference at any time can be seen in ”u28 Temp. ref”.

Diﬀerential

When the temperature is higher than the reference + the set diﬀerential, the compressor relay will be cut in. It will cut out again when the temperature comes down to the set reference.

Setpoint limitation

The controller’s setting range for the setpoint may be narrowed down, so that much too high or much too low values are not set accidentally - with resulting damages.

To avoid a too high setting of the setpoint, the max. allowable reference value must be lowered.

To avoid a too low setting of the setpoint, the min. allowable reference value must be increased.

Correction of the display’s temperature showing

If the temperature at the products and the temperature received by the controller are not identical, an oﬀset adjustment of the shown display temperature can be carried out.

Temperature unit

Here you set whether the controller display is to show temperature values in °C or in °F.

Correction of signal from Sair

Compensation possibility through long sensor cable

Start / stop of refrigeration

With this setting refrigeration can be started, stopped or a manual override of the outputs can be allowed. Start / stop of refrigeration can also be accomplished with the external switch function connected to a DI input. Stopped refrigeration will give a ”Standby alarm”.

Night setback value

The thermostat’s reference will be the setpoint plus this value when the controller changes over to night operation. (Select a negative value if there is to be cold accumulation.)

Activation of reference displacement

When the function is changed to ON, the thermostat reference will be displaced by the value in r40. Activation can also take place via input DI1 or DI2 (deﬁned in o02 or o37).

Alarm Alarm settings

The controller can give alarm in diﬀerent situations. When there is an alarm, all the light-emitting diodes (LED) will ﬂash on the controller front panel, and the alarm relay will cut in.

Alarm delay (short alarm delay) If one of the two limit values is exceeded, a timer function will commence. The alarm will not become active until the set time delay has been passed. The time delay is set in minutes.

Time delay for door alarm

The time delay is set in minutes. The function is deﬁned in o02 or in o37.

Time delay for cooling (long alarm delay) This time delay is used during start-up, during defrost and immediately after a defrost. There will be change-over to the normal time delay (A03) when the temperature has dropped below the set upper alarm limit. The time delay is set in minutes.

Upper alarm limit

Here you set the alarm limit for the high temperature alarm. The limit is set in °C (absolute value). During night condition, the limit value will be changed with the same value as the night oﬀset. The change will only be applied for positive night oﬀset. The limit value will also be changed in connection with reference displacement r39. Regardless, whether this is positive or negative.

Lower alarm limit

Here you set the alarm limit for low temperature alarms. The limit value is set in °C (absolute value). During night condition, the limit will remain unchanged, while a reference displacement r39, will increase or lower the limit with the value given by r40.

Delay of a DI1 alarm

A cut-out/cut-in input will result in alarm when the time delay has been passed. The function is deﬁned in o02.

Delay of a DI2 alarm A cut-out/cut-in input will result in alarm when the time delay has been passed. The function is deﬁned in o37

Condenser alarm limit

Setpoint for the condenser temperature alarm, the warning level without compressor stop. The alarm will clear when the condenser temperature is decreased with the value deﬁned in parameter A78.

Condenser block alarm limit

Setpoint for the condenser block alarm. Activation of this alarm can trigger an action – light oﬀ, compressor stop or both (see parameter P92) The alarm will clear when the condenser temperature is decreased with 2 times the value deﬁned in parameter A78.

Condenser alarm delay

Delay for the condenser block alarm and potential action. The delay starts when the condenser temperature exceeds the limit in parameter A54.

Condenser alarm diﬀerence

Diﬀerence band below the condenser alarm temperature settings (A37 and A54) for clearing the alarms.

Compressor Compressor control

The compressor relay works in conjunction with the thermostat. When the thermostat calls for refrigeration the compressor relay will be operated.

Running times

To prevent irregular operation, values can be set for the time the compressor is to run once it has been started, and for how long it at least has to be stopped.

The running times are not observed when defrosts start. Min. ON time (in minutes) c01 Min. On time Min. OFF time (in minutes) c02 Min. Oﬀ time

Time delay for couplings of two compressors

Settings indicate the time that has to elapse from the ﬁrst relay cuts in and until the next relay has to cut in.

With data communication the importance of the individual alarms can be deﬁned. Setting is carried out in the “Alarm destinations” menu.

Defrost Defrost control

The controller contains a timer function that is zeroset after each defrost start. The timer function will start a defrost if/when the interval time is passed. The timer function starts when voltage is connected to the controller, but it is displaced the ﬁrst time by the setting in d05. If there is power failure, the timer value will be saved and continue from here when the power returns. This timer function can be used as a simple way of starting defrosts, but it will always act as safety defrost if one of the subsequent defrost starts is not received. The controller also contains a real-time clock. By means of settings of this clock and times for the required defrost times, defrost can be started at ﬁxed times of the day. If there is a risk of power failure for periods longer than four hours, a battery module should be mounted in the controller. Defrost start can also be accomplished via data communication, via contact signals or manual start-up. All starting methods will function in the controller. The diﬀerent functions have to be set, so that defrosts do not ”come tumbling” one after the other. Defrost can be accomplished with electricity or hot gas. The actual defrost will be stopped based on time or temperature with a signal from a temperature sensor.

Defrost method

Here you set whether defrost is to be accomplished with electricity, gas or "non". During defrost the defrost relay will be cut in.

Defrost stop temperature

The defrost is stopped at a given temperature which is measured with a sensor (the sensor is deﬁned in d10).

The temperature value is set.

Interval between defrost starts

The function is zeroset and will start the timer function at each defrost start. When the time has expired the function will start a defrost. The function is used as a simple defrost start, or it may be used as a safeguard if the normal signal fails to appear. If master/slave defrost without clock function or without data communication is used, the interval time will be used as max. time between defrosts. If a defrost start via data communication does not take place, the interval time will be used as max. time between defrosts. When there is defrost with clock function or data communication, the interval time must be set for a somewhat longer period of time than the planned one, as the interval time will otherwise start a defrost which a little later will be followed by the planned one. In connection with power failure the interval time will be maintained, and when the power returns, the interval time will continue from the maintained value. The interval time is not active when set to 0.

Max. defrost duration

This setting is a safety time so that the defrost will be stopped if there has not already been a stop based on temperature or via coordinated defrost.

Time staggering for defrost cut-ins during start-up

The function is only relevant if you have several refrigeration appliances or groups where you want the defrost to be staggered in relation to one another. The function is furthermore only relevant if you have chosen defrost with interval start (d03). The function delays the interval time d03 by the set number of minutes, but it only does it once, and this at the very ﬁrst defrost taking place when voltage is connected to the controller. The function will be active after each and every power failure.

Drip-oﬀ time

Here you set the time that is to elapse from a defrost and until the compressor is to start again. (The time when water drips oﬀ the evaporator).

Delay of fan start after defrost

Here you set the time that is to elapse from compressor start after a defrost and until the fan may start again. (The time when water is “tied” to the evaporator).

Fan start temperature

The fan may also be started a little earlier than mentioned under “Delay of fan start after defrost”, if the defrost sensor S5 registers a lower value than the one set here.

Fan cut-in during defrost

Here you can set whether fan is to operate during defrost. 0: Stopped (Runs during pump down) 1: Running (stopped during "fan delay") 2: Running during pump down and defrost. After that it is stopped.

Defrost sensor Here you deﬁne the defrost sensor. 0: None, defrost is based on time 1: S5 2: Sair

Pumpdown delay

Set the time where the evaporator is emptied of refrigerant prior to the defrost.

Defrost on demand – aggregate refrigeration time

Here the refrigeration time allowed without defrosts is set. If the time is passed, a defrost will be started. With setting = 0 the function is cut out.

Defrost on demand – S5 temperature

The controller will follow the eﬀectivity of the evaporator, and via internal calculations and measurements of the S5 temperature it will be able to start a defrost when the variation of the S5 temperature becomes larger than required. Here you set how large a slide of the S5 temperature can be allowed. When the value is passed, a defrost will start.

The function can only be used in 1:1 systems when the evaporating temperature will become lower to ensure that the air temperature will be maintained. In central systems the function must be cut out.

With setting = 20 the function is cut out

Max. duration of -d- in the display

Controls the readout of "-d-" after defrost, so that "-d-" is shown until the temperature is ok, the set delay has expired, or a temperature alarm becomes active.

If you wish to see the temperature at the defrost sensor, push the controller’s lowermost button.

If you wish to start an extra defrost, push the controller’s lowermost button for four seconds. You can stop an ongoing defrost in the same way.

Miscellaneous Miscellaneous Delay of output signal after start-up

Start-up after a power failure the controller’s functions can be delayed so that overloading of the electricity supply network is avoided. Here you can set the time delay.

Digital input signal - DI1

The controller has a digital input 1 which can be used for one of the following functions: Oﬀ: The input is not used

1. Status display of a contact function

2. Door function: When the input is open it signals that the door is open. The refrigeration and the fans are stopped. When the time setting in “A4” is passed, an alarm will be given and refrigeration will be resumed.

3. Door alarm: When the input is open it signals that the door is open. When the time setting in “A4” is passed, there will be an alarm.

4. Defrost: The function is started with a pulse signal. The controller will register when the DI input is activated. The controller will then start a defrost cycle. If the signal is to be received by several controllers it is important that ALL connections are mounted the same way (DI to DI and GND to GND).

5. Main switch: Regulation is carried out when the input is short-circuited, and regulation is stopped when the input is put in pos. OFF.

6. Night operation: When the input is short-circuited, there will be regulation for night operation.

7. Reference displacement when DI1 is short-circuited. Displacement with “r40”.

8. Separate alarm function: Alarm will be given when the input is short-circuited.

9. Separate alarm function: Alarm will be given when the input is opened. (For 8 and 9 the time delay is set in A27)

10. Case cleaning: The function is started with a pulse signal. Cf. also description on page 4.

If the controller is built into a network with data communication, it must have an address, and the master gateway of the data communication must then know this address. These settings can only be made when a data communication module has been mounted in the controller and the installation of the data communication cable has been ﬁnished. This installation is mentioned in a separate document “RC8AC”.

The address is set between 1 and 60 (119), gateway determined. o03 The address is sent to the gateway when the menu is set in pos. ON

IMPORTANT: Before you set o04, you MUST set o61. Otherwise you will be transmitting incorrect data.

Access code 1 (Access to all settings)

If the settings in the controller are to be protected with an access code you can set a numerical value between 0 and 100. If not, you can cancel the function with setting 0. (99 will always give you access).

Max. standby time after coordinated defrost

When a controller has completed a defrost it will wait for a signal which tells that the refrigeration may be resumed. If this signal fails to appear for one reason or another, the controller will itself start the refrigeration when this standby time has elapsed.

Digital input signal - D2

The controller has a digital input 2 which can be used for one of the following functions: Oﬀ: The input is not used.

1. Status display of a contact function

3. Door alarm: When the input is open it signals that the door is open. When the time setting in “A4” is passed an alarm will be given.

5. Main switch: Regulation is carried out when the input is short-circuited, and regulation is stopped when the input is put in pos. OFF.

6. Night operation: When the input is short-circuited, there will be regulation for night operation.

7. Reference displacement when DI2 is short-circuited. Displacement with “r40”.

8. Separate alarm function: Alarm will be given when the input is short-circuited.

9. Separate alarm function: Alarm will be given when the input is opened.

10. Case cleaning: The function is started with a pulse signal. Cf. also description on page 4.

11. Not used

12. The input is used for coordinated defrost in conjunction with other controllers of the same type.

Conﬁguration of light function (relay 4 in applications 2 and 6)

1) The relay cuts in during day operation

2) The relay to be controlled via data communication

3) The relay to be controlled by the door switch deﬁned in either o02 or o37 where

the setting is selected to either 2 or 3. When the door is opened the relay will cut in. When the door is closed again there will be a time delay of two minutes before the light is switched oﬀ.

Activation of light relay

The light relay can be activated here, but only if deﬁned in o38 with setting 2.

Rail heat during day operation

The ON period is set as a percentage of the time.

Rail heat during night operation

The ON period is set as a percentage of the time.

Rail heat cycle

The period of time for the aggregate ON time + OFF time is set in minutes.

Case cleaning

The status of the function can be followed here or the function can be started manually. 0 = Normal operation (no cleaning) 1 = Cleaning with fans operating. All other outputs are Oﬀ. 2 = Cleaning with stopped fans. All outputs are Oﬀ. If the function is controlled by a signal at the DI1 or DI2 input, the relevant status can be seen here in the menu.

Selection of application

The controller can be deﬁned in various ways. Here you set which of the 5 applications is required. On page 6 you can see a survey of applications.

This menu can only be set when regulation is stopped, i.e. “r12” is set to 0.

Transfer a set of presettings to the controller

It is possible to select a quick setting of a number of parameters. It depends on whether an application or a room is to be controlled and whether defrost is to be stopped based on time or based on temperature. The survey can be seen on page 22.

This menu can only be set when regulation is stopped, i.e. “r12” is set to 0.

After the setting, the value will return to 0. Any subsequent adjustment/setting of parameters can be made, as required.

Access code 2 (Access to adjustments)

There is access to adjustments of values, but not to conﬁguration settings. If the settings in the controller are to be protected with an access code you can set a numerical value between 0 and 100. If not, you can cancel the function with setting 0. If the function is used, access code 1 (o05) must also be used.

Save as factory setting

With this setting you save the controller’s actual settings as a new basic setting (the earlier factory settings are overwritten).

Runtime readout

Readout of the accumulated controller runtime in days (powered up and main switch on). Can be cleared or adjusted when r12 Main switch is oﬀ.

Fault message Alarms

In an error situation the LEDs on the front will ﬂash and the alarm relay will be activated. If you push the top button in this situation you can see the alarm report in the display. If there are more keep on pushing to see them. There are two kinds of error reports - it can either be an alarm occurring during the daily operation, or there may be a defect in the installation. A-alarms will not become visible until the set time delay has expired. E-alarms, on the other hand, will become visible the moment the error occurs. (An A alarm will not be visible as long as there is an active E alarm). Here are the messages that may appear: 1 = alarm

A1: High temperature alarm High t. alarm

Operating status (Measurement)

The controller goes through some regulating situations where it is just waiting for the next point of the regulation. To make these “why is nothing happening” situations

EKC State:

(Shown in all menu displays) visible, you can see an operating status on the display. Push brieﬂy (1s) the upper button. If there is a status code, it will be shown on the display. The individual status codes have the following meanings:

S0: Regulating 0

S1: Waiting for end of the coordinated defrost 1

S2: When the compressor is operating it must run for at least x minutes. 2

S3: When the compressor is stopped, it must remain stopped for at least x minutes. 3

S4: The evaporator drips oﬀ and waits for the time to run out 4

S10: Refrigeration stopped by main switch. Either with r12 or a DI-input 10

S11: Refrigeration stopped by thermostat 11

S14: Defrost sequence. Defrost in progress 14

S15: Defrost sequence. Fan delay — water attaches to the evaporator 15

S17: Door is open. DI input is open 17

Operation

Display

The values will be shown with three digits, and with a setting you can determine whether the temperature is to be shown in °C or in °F.

Light-emitting diodes (LED) on front panel

The other LEDs on the front panel will light up when the belonging relay is activated.

= Refrigeration = Defrost = Fan running

The light-emitting diodes will ﬂash when there is an alarm. In this situation you can download the error code to the display and cancel/sign for the alarm by giving the top knob a brief push.

Defrost

During defrost a –d- is shown in the display. After defrost is ﬁnished, the readout of –d- will be continued until one of the following conditions are met:

- The temperature is OK (below the cut-in limit)

- A high temperature alarm becomes active

- The delay set with the d40 parameter expires

- The regulation is stopped with “Main switch”

The buttons

When you want to change a setting, the upper and the lower buttons will give you a higher or lower value depending on the button you are pushing. But before you change the value, you must have access to the menu. You obtain this by pushing the upper button for a couple of seconds - you will then enter the column with parameter codes. Find the parameter code you want to change and push the middle buttons until value for the parameter is shown. When you have changed the value, save the new value by once more pushing the middle button.

Examples:

Set menu

1. Push the upper button until a parameter r01 is shown.

2. Push the upper or the lower button and ﬁnd the parameter you want to change.

3. Push the middle button until the parameter value is shown.

4. Push the upper or the lower button and select the new value.

5. Push the middle button again to freeze the value.

Set temperature

1. Push the middle button until the temperature value is shown

2. Push the upper or the lower button and select the new value

3. Push the middle button again to conclude the setting.

Reading the temperature at defrost sensor

• Push the lower button shortly

Manual start or stop of a defrost

• Push the lower button for four seconds. (Though not for application 4).

Get a good start

With the following procedure you can start regulation very quickly:

1 Open parameter r12 and stop the regulation (in a new and not

previously set unit, r12 will already be set to 0 which means stopped regulation.)

2 Select application dependent connections based on the

drawings on page 7.

3 Open parameter o61 and set the electric connection number in

it.

4 Now select one of the preset settings from the table on page 20.

5 Open parameter o62 and set the number for the array of

presettings. The few selected settings will now be transferred to the menu.

6 Open parameter r12 and start the regulation

7 Go through the survey of factory settings. The values in the grey

cells are changed according to your choice of settings. Make any necessary changes in the respective parameters.

8 For network. Set the address in o03 and then install on the

system unit by scanning, or for Lon via setting o04.

Cut-out alarm relay / receipt alarm/see alarm code

• Push the upper button shortly. If there are several alarm codes they are found in a rolling stack. Push the uppermost or lowermost button to scan the rolling stack.

Coordinated defrost via cable connections

Data communication

The controller is available in several versions where data communication can be carried out with one of the following systems: MODBUS or LON-RS485. If data communication is used, it is important that the installation of the data communication cable is performed correctly. See separate literature No. RC8AC…

Electric noise

Cables for sensors, DI inputs and data communication must be kept separate from other electric cables:

- Use separate cable trays

- Keep a distance between cables of at least 10 cm

- Long cables at the DI input should be avoided

The following controllers can be connected up in this way: AK-CC 210, AK-CC 250, AK-CC 450, AK-CC 550 and AK-CC55. Max. 10. Refrigeration is resumed when all controllers have “released” the signal for defrost.
