DI1
Digital input signal.
The defined function is active when the input is short-circuited/
opened. The function is defined in o02.
MODBUS
For data communication.
Terminal 56 = screen
Terminal 57 = A+
Terminal 58 = B(Alternatively the terminals can be connected to an external
display type EKA 163A or 164A, but then they cannot be used
for data communication. Any data communication must then be
carried out by one of the other methods.)
DI2
Digital input signal.
The defined function is active when the input is short-circuited/
opened. The function is defined in o37.
S7, S3, S4, S5, S6
Pt 1000 ohm
S7, brine sensor, placed in the cold inlet before the heat exchanger
S3, air sensor, placed in the warm air before the evaporator
S4, air sensor, placed in the cold air after the evaporator
(the need for either S3 or S4 can be deselected in the
configuration)
S5, defrost sensor, placed on the evaporator
S6, product sensor
Supply voltage
230 V a.c., 50/60 Hz
DO1
Compressor 1
Connection of relay. The coil must be a 230 V a.c. coil.
EKA Display
If there is be external reading/operation of the controller, display
type EKA 163B or EKA 164B can be connected.
RS485 (terminal 51, 52, 53)
For data communication, but only if a data communication
module is inserted in the controller. The module can be a LON
RS485, DANBUSS or a MODBUS.
Terminal 51 = screen
Terminal 52 = A (A+)
Terminal 53 = B (B-)
(For LON RS485 and gateway type AKA 245 the gateway must be
version 6.20 or higher.)
RJ45
For data communication, but only if a TCP/IP module is inserted in
the controller. (OEM)

DO2
Alarm
There is a connection between terminal 7 and 8 in alarm
situations and when the controller is without power.
DO3
Compressor 2
There is connection between terminal 10 and 11 when the
compressor is on.
DO4
Defrost
There is connection between terminal 12 and 14 when
defrosting takes place.
DO5
Fan
There is connection between terminal 15 and 16 when the fan
is on.
Danfoss

AK-CC 460
DO6
Light relay
There is connection between terminal 17 and 18 when the
light must be on.
Data communication
If data communication is used, it is important that the installation
of the data communication cable is performed correctly.
See separate literature No. RC8AC…
DO7
Rail heat
There is connection between terminal 20 and 21 when the rail
heat is on.
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
DI3
Digital input signal
Safety circuits compressor 1 and 2
The signal must have a voltage of 0 / 230 V a.c.
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 wil 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 fit 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.
Coordinated defrost via
cable connections
max. 10
The following controllers can be connected
up in this way:
EKC 204A, AK-CC 210, AK-CC 250,
AK-CC 450, AK-CC 460, AK-CC 550,
Refrigeration is resumed when all
controllers have “released” the signal for
defrost.
Coordinated defrost via
data communication
The setting of controllers to coordinate
their defrosting takes place in the
gateway/system manager.
Refrigeration is resumed when all
controllers have “released” the signal for
defrost.

Operation
Controller/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.
Get a good start
With the following procedure you can start regulation very quickly:
1 Open parameter r12 and start the regulation
2 Go through the survey of factory settings. Make any necessary
changes in the respective parameters.
Light-emitting diodes (LED) on front panel
The LED’s on the front panel will light up when the relevant relay
is activated.
= Refrigeration
= Defrost
= Fan running
3 For network. Set the address in o03
4 Send address to system unit:
• MODBUS: Activate scan function in system unit
• If another data communication card is used in the controller:
- LON RS485: Activate the function o04
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/accept for the alarm by giving the top button a brief
push.
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 button 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 that 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 set the value.
Cutout alarm relay / receipt alarm/see alarm code
• A short press of the upper button
If there are several alarm codes they are found in a rolling stack.
Push the uppermost or lowermost button to scan the rolling
stack.
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 (Or product sensor, if
selected in o92.)
• A short press of the lower button
Manual start or stop of a defrost
• Push the lower button for four seconds.

Configuration of alarm relay
The alarm relay will be activated upon an alarm signal from the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a numerical
value which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor errors).

Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you reconnect the supply voltage
Factory settings are indicated for standard units. Other code numbers
have customized settings.

Fault message
Operating status
In an error situation the LED’s 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.
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:
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 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:
