System survey
A refrigerating plant fitted with ADAP-KOOL
®
refrigeration controls will mostly consist of several
controllers or monitoring units, where each controller will regulate its own refrigeration
appliance/cold room.
The system has been designed in such a way that contact can be made to each and every
controller via a data communication system. One specific controller is selected, and it will now
be possible to make settings and readouts for this unit.
The individual monitoring units type AKL 111A can be
operated in two ways:
1. With control panel type AKA 21.
Use this document when operation takes place in this
way.
2. With PC and system software type AKM. Use another
document with literature number RC.1H.6.
Operation
Validity
This menu operation (dated October 2000), applies to AKL 111A with the code number
084B6039 fitted with software version 2.0x.
AKL 111A Version 2.0x Menu operation RC.1H.51.02 © Danfoss 10/2000 3
All controllers that are connected to the same network can be operated with the control panel.
There may be as many as 125 controllers, and they are shown in groups of 16 on the display.
A system is shown here which consists of more than 16 controllers. The meaning of the letters
is, as follows:
A: AKC or AKL controller
E: Controller with active ERROR (on addresses 2, 11 and 12 in this example)
g: Gateway (to addresses 13 and 14 in this example)
G: Gateway with connected printer
: A blank field indicates that there is no unit with this address.
Select the unit that is to be operated by using the “+/On” or “-/Off” key, and push “Enter”. In this
example you select the controller with address 4.
If the system comprises more than 16 units or units with an address code higher than 16, you
may change to the next group by pushing "®".
When a controller has been selected, you can make settings in it. This setting is performed, as
follows:
Shown in the upper right corner of the display is the setting with which the controller is
operating. Below that value a new setting may be made. Use the three keys “+/ON”, “-/OFF”
and “Digit” for setting the new value. This new value will not govern the regulation until you
push the key “Enter”.

The functions in the controller can be protected by means of an access code. Depending on
the settings to be made, you may gain access in one of the following ways:
User input: Gives access to:
1. Push F1 Display of alarms
2. Push F2 Readout of actual values
3. Code 1 and then F1 Acknowledgement of alarms
Code 1 and then F3 Setting of selected parameters
4. Code 2 Operation of all settings of the entire menu system
(with system software type AKM there is access to
additional functions).
Pages 6 and 7 contain a description of how you gain access to the system via a code.

A supporting text is attached to the individual functions. When such a function is shown in the
control panel’s display, the supporting text can be obtained by pushing the key “Help”. The
supporting text is intended as a help to users who no longer use these operating instructions.
In the menus shown below functions with supporting texts are identified with the word “Help”
next to the function.
When an error appears in a system, it can be seen on the control panel’s display which will
show an “E”. If the control panel shows a text from a selected controller, the LED at the word
“Alarm” will flash.
When an error has occurred, first select the controller on which the error is registered. When
the controller has been found, push “F1”, and the error message will appear.
At the end of the document there is a list of all the error messages and a description of how to
acknowledge an alarm.

When one controller has been selected from the total system, the following display will
appear (the display is the first one shown when you have selected an address from the total
system):
e.g.
AKL 111A Adr: 2
E Mon-11:27
From this position you can freely choose between several forms of operating levels:
1. Display of alarms - push “F1”
2. Display and setting of a few selected functions - push “F2”
3. Display and setting of several selected functions - push “F3”
The function may be protected with a code (code 1)
4. Display and setting of all allowed functions in the controller. The function may be protected
with a code (code 2).
Operation of the individual levels is shown below:
When you push “F1” the alarm messages from the controller in question appear. Only active
alarms are shown. With a push on "¯" you can see whether there are more alarm messages,
and if so, their texts.
When an alarm has been localised and corrected, the alarm is acknowledged (removed from
the system, so that it no longer appears). In large systems where a gateway is also connected
this acknowledgement will take place automatically. In other systems it has to be done
manually, cf. end of the document.
Prior to the acknowledgement of the alarm, the keying of a code is required, see page 6.
Leave the F1 function by pushing "¬".
