Controller tray for refrigeration appliance controller with signal from external controller

AK-CT 200A + AK-CT 201A

ADAP-KOOL® Refrigeration control systems

Introduction

Application

The controller is a complete auxiliary relay module with great exibility for adaptation of signals from an external controller. The controller is optimised for connection of loads on refrigeration appliances and cold rooms, as well as for controlling the light and night blind.

Advantages

• Optimised for installation by manufacturer

• Electricity-controlled and voltage controlled relay connections

• Loads requiring electricity can be connected directly

• One controller for several dierent refrigeration appliances

• Quick set-up with predened settings

• Built-in data communication

Principle

There are 8 digital inputs, all of which can be dened to connect to the 8 outlet relays. The relays are controlled by an internal measurement circuit that ensures an optimum connection time on the sine curve. The optimum time allows connections to be made with loads of up to 16 A on individual relays. The current through each relay will be measured continuously, and if it becomes higher than the set permissible value, the relay will cut out and an alarm will be issued.

Functions

- Relays controlled by an external controller, e.g.:

• Compressor and possibly compressor 2

• Defrosting with 1, 2 or 3 phases

• Rail heat

• Fans and fans in eco-operation

• Light and possibly extra lighting

• Night blind

- AK-CT 200A has an alarm relay that is activated for alarms issued as the result of the cut-out of a relay due to excess current.

Applications

The controller can connect functions to dierent refrigeration

appliances, such as:

• Standard appliances or cold rooms with one evaporator and one cooling section.

• Refrigeration appliances with two evaporators and two cooling sections.

• Refrigeration appliances with one evaporator and two cooling sections.

The external controller determines which functions are to be engaged.

A setting will congure the inputs and outputs, so that one input is destined for a specic relay output.

Installation benets

The controller is designed to provide a number of advantages when installed by the refrigeration appliance manufacturer, such as:

High relay load

Load connection/disconnection is controlled by a voltage measurement and a current measurement, so that the relay’s switch function can operate under optimal conditions. The controller can then connect loads of up to 16 A, without the use of auxiliary relays.

Spring clamps

All cable connections are made using plugs with spring switches. This allows for fast and easy installation.

Parallel power point

Several of the outlets have double or triple connections points, so the use of external loop clips is not usually necessary.

Structure of the controller

The controller consists of hardware type AK-CT 200A and a software identity code AK-CT 201A. This software identity code is delivered in a separate plug and must be placed in an RJ45 plug in the hardware. It is rst necessary to mount the plug when conguring the controller.

AK-CT 201A User Guide RS8GT502 © Danfoss 2016-10 3

Operation

Digital inputs

There are six digital inputs with contact function and two digital inputs with high voltage signal. They can be used for the following functions:

• Receive signals from an external controller and then activate the associated relay.

• Receive signals from switches for the activation of light and night blind.

Light function

The function can be used for controlling the light in a refrigeration appliance or in a cold room. The light function can be dened in two ways:

• The light is controlled by a DI input

• Two signals, both of which can be on before the light goes on. One can be a DI contact signal at the appliance (fx DI3) and the other can be a voltage signal on DI7.

Extra light (light 2) Light 2 can also be activated by one DI input, e.g. DI4. It can also be controlled with two signals. For two signals, the second signal must be sent with a voltage signal on DI8.

Night blind

Motorised night blind can be controlled automatically from the controller. The night blinds will follow the status of the light function. When the light is switched on, the night blinds opens and when the light is switched o, the night blinds close again. When the night blinds are closed, it is possible to open them using a pulse signal on the digital input. If this input is activated, the night blinds will open and the refrigeration appliance can be lled with new products. If the input is activated again, the blinds close again. If the activation is omitted, the blind will close automatically when the delay time expires. A setting is used to dene whether the light is to be on or o when the night blind is up. This pulse signal must be connected to one of the following inputs: DI5, DI7 or DI8.

DI7 DI3

Light 1 controlled by DI7 and fx DI3.

Light 2 (extra light) controlled by DI8 and fx DI4.

Override of light 1

Data communication

The controller has xed built-in MODBUS data communication. It can be connected to a Danfoss system unit, if required.

If there is a requirement for a dierent form of data communication, a Lon RS 485 module can be inserted in the controller. The connection must then be to terminal RS 485.

(To use a Lon RS 485 module and gateway type AKA 245 the module must be Version 6.20 or higher.)

Important

All connections to the data communication MODBUS and RS 485 must comply with the requirements for data communication cables. See literature: RC8AC.

Display

The controller has two plugs for a display. Here display type EKA 163B or EKA 164B (max. length 15m) can be connected. EKA 163B is a display for readings. EKA 164B is both for readings and operation.

During standard operation the display will read “ON”. If one of the relays cuts out due to overcurrent, three LEDs will ash on the display. In this situation, you can access the alarm list on the display by pressing the top button.

It is possible to connect two displays. There are identical signals on both plugs.

Applications

Here is a survey of the controller’s eld of application. The applications are all adapted for commercial refrigeration systems in the form of either refrigeration appliances or cold storage rooms.

Eight connection diagrams are shown on the following pages. We recommend using the connection diagram that comes closest to the application. This will result in the greatest degree of equalisation in the three phases. Some functions are permanently bound to certain outputs. In this case, the connection diagram must be followed. The functions are:

• Defrosting. Here is one or more of the DO outputs used, depending whether the application is a one, two or three-phase defrosting.

• Fan stop, when the night blind is down. In this case, DO7 is disconnected.

• Fan ECO function. DO8 is engaged.

Outputs There are 8 inputs and 8 outputs. Each output can be engaged by any input, which receives a signal from an external controller or other switch function.

Alarm output The alarm relay will be released when the controller registers an error, e.g. when a relay is disconnected due to excess current.

Digital input DI1 to DI6 is the on/o input that can be used, for example, for one of the following functions: activate a relay for e.g. compressor, defrosting, fan, light, cancel defrost, etc. DI7 and DI8 are 230 V inputs that can activate similar functions. See the functions in the respective settings o84, etc. There are limitations on DO1 and DO2. They can only be used for signals from the external controller.

Control of night blinds Night blinds follow the status of the light function – when the light is switched on, the night blinds are up and when the light is switched o, the night blinds are down. In addition a digital input provides the option of forced opening of the blinds so that the appliance can be lled with products.

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.

Installation considerations

Accidental damage, poor installation, or site conditions, can give rise to malfunctions of the control system, and ultimately lead to a plant breakdown. Every possible safeguard is incorporated into our products to prevent this. However, a wrong installation, for example, could still present problems. Electronic controls are no substitute for normal, good engineering practice. Danfoss will not be responsible for any goods, or plant components, damaged as a result of the above defects. It is the installer's responsibility to check the installation thoroughly, and to t the necessary safety devices. Special reference is made to the necessity of signals to the controller when the compressor is stopped and to the need of liquid receivers before the compressors. Your local Danfoss agent will be pleased to assist with further advice, etc.

Extra connection/terminal strip

There are 3 holes on the base in which a terminal strip (type Wago 862-8593) can be mounted. There are holes for 2 terminal strips.

ID-module AK-CT 201A

This module contains a code which release a regulation with a extern controller.

The installation and removal of the module must always be performed while the appliance is voltage-free.

Stripping wire The following demands for stripping, so the insulation does not enter the spring clip.

When the module is inserted in the plug, the controller can be set. The settings will be saved in both the controller and the module. A module with settings will always overwrite the settings in the controller. An overwrite will be nished 3 seconds after the controller is turned on.

The module can be removed from the controller for a short period of time in order to transfer the settings to another, corresponding controller. Remember to disconnect the voltage to ensure the system is voltage-free.

If the controller registers a missing module, an alarm will be issued. This alarm will be regularly repeated until the module is inserted in the controller again. If the controller is without a module for a longer period of time (several days), the regulation will stop and all outputs are reset.

If it becomes necessary to erase all settings from the module, it can be inserted into the controller and setting P61 can then be activated. Then remove the module without restarting the controller.

A factory-new or “empty” module can be used to retrieve settings based on a corresponding controller. Insert the module into the controller from which the settings are to be retrieved. Turn on voltage. Wait 3 seconds. Turn o again. The module now contains all settings — including the Modbus address. Remember to change the address when the module has been inserted into the receiving apparatus.

Miscellaneous Miscellaneous Delay of output signal after start-up

After start-up or 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.

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.
