DI1 Digital input signal. The defined function is active when the input is short-circuited/ opened. The function is defined in o02.
EKA Display If there is be external reading/operation of the controller, display type EKA 163B or EKA 164B can be connected.
DI2 Digital input signal. The defined function is active when the input is short-circuited/ opened. The function is defined in o37.
Pressure transmitter AKS 32R
Connect to terminal 30, 31 and 32. (Used cable 060G1034: Black=30, Blue=31, Brown=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.
S2, S6 Pt 1000 ohm sensor
S6 / S5B / S3B, product sensor or defrost sensor B or air sensor B. The application determines which.

(the need for either S3 or S4 can be deselected in the configuration) S5, defrost sensor, placed on the evaporator
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)
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.)

Coordinated defrost via cable connections
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 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.

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 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 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.
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 freeze 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

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 enabled for alarm
16 – Defrosting alarms 32 – Miscellaneous 64 – Injection alarms
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 error and 0 will cancel the relay function).

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
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:

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 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:
Normal regulation
S0
Waiting for end of the coordinated defrost
S1
When the compressor is operating it must run for at least S2 x minutes. When the compressor is stopped, it must remain stopped S3 for at least x minutes. The evaporator drips off and waits for the time to run out S4
Refrigeration stopped by main switch. Either with r12 or S10
a DI-input
Refrigeration stopped by thermostat
S11
Defrost sequence. Defrost in progress
S14
Defrost sequence. Fan delay — water attaches to the
S15

Refrigeration stopped due to open ON input or stopped S16 regulation

*) Emergency cooling will take effect when there is lack of signal from a defined S3 or S4 sensor or signal from the pressure transmitter is outside signal range. The regulation will continue with a registered average cutin frequency. There are two registered values one for day operation and one for night operation.
Data communication The importance of individual alarms can be defined with a setting. The setting must be carried out in the group “Alarm destinations”
