Principles
The great advantage of this series of controllers is that it can
be extended as the size of the plant is increased. It has been
developed for refrigeration control systems, but not for any
specic application – variation is created through the read-in
software and the way you choose to dene the connections.
It is the same modules that are used for each regulation and the
composition can be changed, as required. With these modules
(building blocks) it is possible to create a multitude of various
kinds of regulations. But it is you who must help adjusting the
regulation to the actual needs – these instructions will assist you
to nd your way through all the questions so that the regulation
can be dened and the connections made.
Controller
Top part
Advantages
• The controller’s size can “grow” as systems grow
• The software can be set for one or more regulations
• Several regulations with the same components
• Extension-friendly when systems requirements are changed
• Flexible concept:
- Controller series with common construction
- One principle – many regulation uses
- modules are selected for the actual connection requirements
- The same modules are used from regulation to regulation
Extension modules
Bottom part
The controller is the cornerstone of the regulation. The module has inputs and
outputs capable of handling small systems.
• The bottom part – and hence the terminals – are the same for all controller types.
• The top part contains the intelligence with software. This unit will vary according
to controller type. But it will always be supplied together with the bottom part.
• In addition to the software the top part is provided with connections for data
communication and address setting.
Examples
A regulation with few connections can
be performed with the controller module
alone
If the system grows and more functions have to be controlled, the regulation can be
extended.
With extra modules more signals can be received and more relays cut in and out
– how many of them – and which – is determined by the relevant application.
If there are many connections one or more
extension modules have to be mounted

Direct connection
Setup and operation of an AK controller must be accomplished via
the “AK-Service Tool” software program.
The programme is installed on a PC, and setup and operation of
the various functions are carried out via the controller’s menu
displays.
Displays
The menu displays are dynamic, so that dierent settings in one
menu will result in dierent setting possibilities in other menus.
A simple application with few connections will give a setup with
few settings.
A corresponding application with many connections will give a
setup with many settings.
From the overview display there is access to further displays for
the compressor regulation and the condenser regulation.
At the bottom of the display there is access to a number of general
functions, such as “overview”, “manual operation”, “log function”,
“alarms”, and “service” (conguration).
Network linking
The controller can be linked up into a network together with other
controllers in an ADAP-KOOL® refrigeration control system.
After the setup operation can be performed at a distance with,
say, our software program type AKM.
Users
The controller comes supplied with several languages, one of
which can be selected and employed by the user. If there are
several users, they may each have their choice of language. All
users must be assigned a user prole which either gives access to
full operation or gradually limits the operation to the lowest level
that only allows you “to see”.
AK-LM 340 RS8GV202 © Danfoss 2016-06 5
Light-emitting diodes
A number of light-emitting diodes makes it possible to follow the
signals that are received and transmitted by the controller.
Log
From the log function you can dene the measurements you wish
to be shown.
The collected values can be printed, or you may export them to a
le. You can open the le in Excel or import in AKM.
(The log function is only available via AK-ST 500.)
A log should usually be created on the system unit. The system
unit has a larger memory and can contain more data.
If you are in a service situation you can show measurements in a
trend function. The measurements are then made real-time and
displayed instantly.

2. Design of a controller
This section describes how the monitoring unit is designed.
The controller in the system is based on a uniform connection
platform where any deviations from regulation to regulation is
determined by the used top part with a specic software and
by which input and output signals the relevant application will
require. If it is an application with few connections, the controller
module (top part with belonging bottom part) may be sucient.
If it is an application with many connections it will be necessary to
use the controller module plus one or more extension modules.
This section will give you a survey of possible connections plus
assistance in selecting the modules required by your actual
application.
AK-LM 340 RS8GV202 © Danfoss 2016-06 7
Module survey
• Controller module – capable of handling minor plant requirements.
• Extension modules. When the complexity becomes greater
and additional inputs or outputs are required, modules can be
attached to the controller. A plug on the side of the module will
transmit the supply voltage and data communication between
the modules.
• Top part
The upper part of the controller module contains the
intelligence. This is the unit where the regulation is dened and
where data communication is connected to other controllers in a
bigger network.
• Connection types
There are various types of inputs and outputs. One type may, for
example, receive signals from sensors and switches, another may
receive a voltage signal, and a third type may be outputs with
relays etc. The individual types are shown in the table below.
Extension module with
additional analog inputs
• Optional connection
When a regulation is planned (set up) it will generate a need for
a number of connections distributed on the mentioned types.
This connection must then be made on either the controller
module or an extension module. The only thing to be observed
is that the types must not be mixed (an analog input signal must
for instance not be connected to a digital input).
• Programming of connections
The controller must know where you connect the individual
input and output signals. This takes place in a later conguration
where each individual connection is dened based on the
following principle:
- to which module
- at which point (”terminals”)
- what is connected (e.g. pressure transmitter/type/
pressure range)
Extension module with additional
relay outputs and additional
analog inputs.
Bottem part
Controller with analog inputs and
relay outputs.
Top part
The module with additional relay outputs is
also available in a version where the top part
is provided with change-over switches so
that the relays can be overridden.

Controller
Function
There are several controllers in the series. The function is
determined by the programmed software, but outwardly the
controllers are identical – they all have the same connection
possibilities:
11 analog inputs for sensors, pressure transmitters, voltage signals
and contact signals.
8 digital outputs, with 4 Solid state outputs and 4 relay outputs
Supply voltage
24 V a.c. or d.c. to be connected to the controller.
The 24 V must not be retransmitted and used by other controllers
as it is not galvanically separated from inputs and outputs. In
other words, you must use a transformer for each controller. Class
II is required. The terminals must not be earthed.
The supply voltage to any extension modules is transmitted via
the plug on the right-hand side.
The size of the transformer is determined by the power
requirement of the total number of modules.
The supply voltage to a pressure transmitter can be taken either
from the 5 V output or from the 12 V output depending on
transmitter type.
PIN
Data communication
If the controller is to be included in a system, communication
must take place via the LON connection.
The installation has to be made as mentioned in the separate
instructions for LON communication.
Address setting
When the controller is connected to a gateway type AKA 245,
the controller’s address must be set between 1 and 119. (If it is a
system manager AK-SM .., then 1-200).
Service PIN
When the controller is connected to the data communication
cable the gateway must have knowledge of the new controller.
This is obtained by pushing the key PIN. The LED “Status” will ash
when the gateway sends an acceptance message.
Operation
The conguration operation of the controller must take place from
the software programme “Service Tool”. The program must be
installed on a PC, and the PC must be connected to the controller
via the network plug on the front of the unit.
Light-emitting diodes
There are two rows with LED’s. They mean:
Left row:
• Voltage supply to the controller
• Communication active with the bottom PC board (red = error)
• Status of outputs DO1 to DO8
Right row:
• Software status (slow ash = OK)
• Communication with Service Tool
• Communication on LON
• Communication with AK-CM 102
• Alarm when LED ashes
