7 MultiFlex PAK E2 In-
terface
The MultiFlex PAK is capable of communi-
cating with an E2 RX refrigeration controller
version 2.10 and above, or an Einstein RX
refrigeration controller with software version
1.83 or above.
In order to take advantage of new E2 and
PAK features such as Danfoss EKC514 integra-
tion, the E2 must be version 2.60 or above. The
Einstein RX and E2 versions before 2.60 do not
support Danfoss EKC514 or some of the
advanced features of suction float.
Using MultiFlex PAK boards with a central
Einstein controller offers several benefits over
simple stand-alone PAK control, including:
• Reporting of PAK-related alarms in the
Alarm Advisory Log
• The ability to log PAK inputs in an E2 log-
ging group
• Remote access to PAK status and program-
ming from the E2 front panel or remote com-
munication tools (InSite or UltraSite32).
Communication between E2 and a PAK
takes place over the RS485 I/O Network. Follow
the instructions in
Section 3, The I/O Network ,
to connect the PAKs to the E2 I/O network.
Then, follow the instructions in this chapter to
set up the PAKs.

7.1.1. Adding a PAK
Before an E2 will communicate with a PAK,
it must be added as an I/O board. This task is per-
formed in the Controller Setup screen. To access
this screen:
NOTE: Unlike other MultiFlex board types,
the PAK will NOT automatically show as
"Online" in the Online Status screen. You must
first set the "Connected" parameter in the PAK
application to "Yes." See
Section 7.2., Setting
the "Connected" and "Read Setpoints" Attri-
butes
