3.0 Appendix
Site Survey considerations
Location of Com-Trol 4k2 or 4k2e - Note whether box mount or panel-mount.
Modem location (6k)
Danfoss Logger requirements?
Location of CWeb or 5K (if applicable)
Leak detector location and type
Note any HGM 300 units and number of zones
Document Com-Trol hardware copyright dates. Dates prior to 1998 will cause compatibility issues (see figure 7)
Determine optimum Ethernet switch location and Cat5 cable length
Danfoss highly recommends that all power, communications, grounding connections and termination resistors
pertaining to the Com-Trol I/O boards are reviewed before conversion to the Danfoss AK 255.
Note any global bus devices that exist and considerations for each (Energy meters, lighting panels, etc.)
Figure 7 - example of Com-Trol I/O board with copyright date of 1994 - this is
not
compliant or suitable for a Danfoss retro-fit
operation. Seek to have older boards (pre 1998) to be either replaced with Danfoss I/O or newer Com-Trol I/O
