2.0 Programming AK-SC255 Database

One of the central tasks involved in retro-fitting the Com-Trol front end unit is the configuration of the AK-SC255 database that
allows the Danfoss controller to fully replace the Com-Trol unit(s). Review the following section for guidance in creating the
AK-SC255 database, which replaces the Com-Trol 4k2/4K2e systems.
1
Using the Com-trol EZCom software, pull back and save the existing Com-Trol 4K or 4K2e controllers to be converted to
the Danfoss AK-SC255
2
The Com-Trol files can be viewed with the Com-Trol EzSet software utility
3
Using the Danfoss AKA65 software service tool, create a blank database by using the simulate function. Ensure the correct
version of simulated database is created to avoid compatibility issues on site (i.e. use the same version for the database pro-
gramming that will be installed in the physical AK-SC255 unit)
3a
Start configuration of the AK-SC255 database by setting the Legacy I/O type to COMTL (found in the Store Info /
Preferences) Figure 4
3b
Configure the Modbus channel under the Communications / I/O Network / Rescan Channels page. If Danfoss AK I/O
boards are also to be used, ensure the channel 'LonWorks' is checked also. Figure 5
