Application - Danfoss AK-CC 550B User Manual

Applications
Here is a survey of the controller's field of application.
A setting will define the relay outputs so that the
controller's interface will be targeted to the chosen

application.

On page 28 you can see the relevant settings for the
respective wiring diagrams.
General:
The ten uses are all adapted for commercial
refrigeration systems in the form of either
refrigeration appliances or cold storage rooms.
In general all have outputs for:
• AKV valve
• Fan
• Defrost
In addition they have different uses and thereby
input and outputs.
Application 1-4
Standard applications.
This is for standard use where the vital difference
is only different combinations of the following
functions/outputs:
• Alarm
• Rail heat
• Compressor
• Light

S3 and S4 are temperature sensors. The application will determine whether
either one or the other or both sensors are to be used. S3 is placed in the air
flow before the evaporator. S4 after the evaporator.
A percentage setting will determine how the control is to be based. S5 is a
defrost sensor and is placed on/in the fins of the evaporator.
S6 is a product sensor, but in application 9 it has a different use.
DI1, DI2 and DI3 are contact functions that can be used for one of the fol-
lowing functions: door function, alarm function, defrost start, external main
switch, night operation, change of thermostat reference, appliance cleaning,
forced refrigeration or coordinated defrost. DI3 has a 230 V input. See the
functions in settings o02, o37and o84.
