DI1
Digital input signal. The defined function is active when the input is short-circuited/
opened. The function is defined in o02.
DI2
Digital input signal. The defined function is active when the input is short-circuited/
opened. The function is defined in o37.
Pressure transmitter or temperature sensor S1
Pe / AKS 32R (pressure measurement recommended)
Connect to terminal 30, 31 and 32.
The signal from one pressure transmitter can be received by up
to 10 controllers. But only if there are no significant pressure
decreases between the evaporators to be controlled.
S1 (correct location is important to ensure correct measurements)
Pt 1000 ohm sensor
Connect to terminal 31 and 32.
S2
Pt 1000 ohm sensor
S3, S4, S5, S6
Pt 1000 ohm sensor or PTC 1000 ohm sensor. All have to be of
the same type.
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 or defrost sensor B or air sensor B.
The configuration determines which.

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 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.
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.)
Supply voltage
230 V a.c.
Instructions RI8LN352 © Danfoss 10/2007 AK-CC 550
DO1
Connection of expansion valve type AKV or AKVA. The coil must
be a 230 V a.c. coil.
DO2
Alarm
There is a connection between terminal 7 and 8 in alarm
situations and when the controller is without power.
Rail heat and heating element in drip tray
There is connection between terminal 7 and 9 when heating
takes place.
Night blind
There is connection between terminal 7 and 9 when the night
blind is up.
Suction line valve
There is connection between terminal 7 and 9 when the
suction line must be open.
DO3
Refrigeration, Rail heat, Heat function, Defrost 2
There is connection between terminal 10 and 11 when the
function must be active.
Heating element in drip tray
There is connection between terminal 10 and 11 when heating
takes place.
DO4
Defrost
There is connection between terminal 12 and 14 when
defrosting takes place.
Hot gas / drain valve
There is connection between terminal 13 and 14 during normal
operation. There is connection between terminal 12 and 14 when the hot
gas valves must open.
DO5
Fan
There is connection between terminal 15 and 16 when the fan
is on.
DO6
Light relay
There is connection between terminal 17 and 18 when the
light must be on.
Rail heat, Compressor 2
There is connection between terminal 17 and 19 when the
function must be active.
DI3
Digital indput signal. The signal must have a voltage of 0 / 230 V AC.
The function is defined in o84.
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…
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 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
The following controllers can be connected
up in this way:
EKC 204A, AK-CC 210, AK-CC 250,
AK-CC 450, 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
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 stop the regulation (in a new and not
previously set unit, r12 will already be set to 0 which means
stopped regulation.)
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 runing
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 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 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.
3 Open parameter o61 and set the electric connection number in
it

8 Open parameter r12 and start the regulation
9 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.
10 For network. Set the address in o03
11 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
