System survey

A refrigerating plant fitted with ADAP-KOOL

refrigeration controls will mostly consist of

several controllers 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 controllers 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.

Operation

Validity

This menu operation was worked out in September 2000 and applies to AKC 114P

and AKC 115P with the following code numbers:

084B6182 (AKC 114P)

084B6183 (AKC 115P)

that are fitted with software version 1.5x.

AKC 114P-115P Version 1.5x Menu operation RC.8A.N1.02 © Danfoss 09/2000 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 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”.

Select a controller

Settings of a controller

-50 to +50 5

OFF / ON ON

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 Reading of selected temperatures, change of

temperature in the refrigeration appliance, start of

defrost

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 furthermore 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.

Supporting text

How to localise an error

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.

AKC 115P 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

Leave the F1 function by pushing “¬”.
