Danfoss AK-PC 530 User Manual page 9

Address
If the controller is built into a network with data communication, it must have an
address, and the master gateway of the data communication must then know this
address.
These settings can only be made when a data communication module has been
mounted in the controller and the installation of the data communication cable has
been completed.
This installation is mentioned in a separate document "RC8AC".
The address is set between 1 and 240 (gateway determined)
The address is sent to the gateway when the menu is set in pos. ON
Access code
If the settings in the controller are to be protected by a numerical code, you can set a
numerical value between 0 and 100. If not, you can cancel the function with setting
OFF.
Special settings
Outputs DO9 and DO10 are normally used for the "AKD start/stop" function and for the alarm
function, but they may be redefined in special cases.
DO9 function:
0: AKD Start/stop
1: Inject-on function (see drawing below)
2: Boost ready function (see drawing below)
3: Fan relay
(If "c16" is set to 18, "o75" will automatically be set to unloader relay for compressor 3)
DO10 function:
0: Alarm relay
1: Fan relay
Status on the digital inputs
The signal on the DI inputs can be read in the following menus:
Status on DI 1
Status on DI 2
Status on DI 3
Status on DI 4
Status on DI 5
Configuration settings (compressor and fan definitions, coupling mode and refrigerant) can only take place when regulation is stopped.
Warning ! Direct start of compressors *
To prevent compressor breakdown parameter c01 and c07 should be set according to suppliers requirements or in general :
Hermetic Compressors c07 min. 5 minutes
Semihermetic Compressors c07 min. 8 minutes and c01 min. 2 to 5 minutes ( Motor from 5 to 15 KW )
* ) Direct activating of solenoid valves does not require settings different from factory (0)
DO9 function:
Inject-on function
DO9 is here used for the Inject ON function. Here all the electronic expansion valves are closed when all the compressors are stopped
and P0 > +Zone.
Wiring is carried out as shown below.
The function may however also be generated via data communication. In this way the relay output is made available for other
applications.
Boost ready function
If two controllers are to capacity regulate the high-temperature part and the low-temperature part, respectively, they must be
connected in such a way that low-temperature regulation cannot be started until the high-temperature part is operating. The signal
can be taken from DO9 of one controller and received on the ON input of the other controller.
Example:
AK-PC 530 Manual RS8EJ302 © Danfoss 05-2010
Following installation of a data com-
munication module, the controller can
be operated on a par with the other
controllers in ADAP-KOOL® refrigera-
tion controls.
