Menu operation via AKA 21 ADAP-KOOL® Controller for controlling evaporators AKC 114A, 115A and 116A Software version 1.5x RC.1M.B2.02 → RC.1M.B3.02 11-1998 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. Operation 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. Use another document with literature number RC.1M.C Validity This menu operation was worked out in November 1998 and applies to AKC 114A, AKC 115A and AKC 116A with the following code numbers: 084B6171 and 084B6172 (AKC 114A) 084B6173 and 084B6174 (AKC 115A) 084B6175 and 084B6176 (AKC 116A) that are fitted with software version 1.5x. 2 Menu operation RC.1M.B3.02 © Danfoss 11/1998 AKC 114A-116A Version 1.5x Select a controller 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. 1 < 1 > 16 AEAAAAAAAAEEgg A 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. 1 < 4 > 16 AEAAAAAAAAEEgg A 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. 17 < AAA 17 > 32 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 “→”. Settings of a controller When a controller has been selected, you can make settings in it. This setting is performed, as follows: -50 to +50 5 5 OFF / ON ON ON 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”. Access to a controller 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: 1. Push F1 2. Push F2 3. 4. Code 1 and then F1 Code 1 and then F3 Code 2 Gives access to: Display of alarms Reading of selected temperatures, change of temperature in the refrigeration appliance, start of defrost Acknowledgement of alarms Setting of selected parameters 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. AKC 114A-116A Version 1.5x Menu operation RC.1M.B3.02 © Danfoss 11/1998 3 Supporting text 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. How to localise an error 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. 1 < 2 > 16 AEAAAAAAAAAAgg A AKC 116A Adr: 2 E Mon-11:27 Standby Mode 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. AKC 116A Adr: 2 E Mon-11:27 Functions of a controller 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: 1. F1 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 “←”. 4 Menu operation RC.1M.B3.02 © Danfoss 11/1998 AKC 114A-116A Version 1.5x 2. F2 When you push “F2” a number of functions will appear where it is possible to read or set values. You can move to and from the individual functions by pushing “↑” or “↓”. On page 3 you can see how a setting is changed. Man.Def.
