Communication Module Ak-Cm 102 - Danfoss AK-PC 772A User Manual

Communication module AK-CM 102

Function
The module is a new communication module, meaning the row of
extension modules can be interrupted.
The module communicates with the regulator via data communi-
cation and forwards information between the controller and the
connected extension modules.
Connection
Communication module and controller fitted with RJ 45 plug con-
nectors.
Nothing else should be connected to this data communication; a
maximum of 5 communication modules can be connected to one
controller.
Communication cable
One metre of the following is enclosed:
ANSI/TIA 568 B/C CAT5 UTP cable w/ RJ45 connectors.
Positioning
Max. 30 m from the controller
(The total length of the communication cables is 30 m)
Supply voltage
24 volt AC or DC should be connected to the communication
module.
The 24 V can be sourced from the same supply that supplies the
controller. (The supply for the communication module is galvani-
cally separated from the connected extension modules).
The terminals must not be earthed.
The power consumption is determined by the power consump-
tion of the total number of modules.
The controller strand load must not exceed 32 VA.
Each AK-CM 102 strand load must not exceed 20 VA.
Point
Connection points on the I/O modules should be defined as if the
modules were an extension of each other.
Address
The address for the first communication module should be set to
1. Any second module should be set to 2. A maximum of 5 mod-
ules can be addressed.
Termination
The termination switch on the final communication module
should be set to ON.
The controller should permanently be set to = ON.
Warning
Additional modules may only be installed following the installa-
tion of the final module. (Here following module no. 11; see the
sketch.)
After configuration, the address must not be changed.
