System survey

Gateway types AKA 245 is a system component to be used in conjunction with controllers in the

ADAP-KOOL® series of controls for refrigerating systems.

When the gateway is used it is possible to build complex control systems with alarm moni toring and

data logging into decentralised refrigerating plant.

All controllers in the AKC series are linked up in a two-core data communication system that is

registered under the name DANBUSS Data Communication System.

A Gateway is the control unit used when the data communication system has to be connected to a PC,

a printer, a TCP/IP server or a modem.

Principle

Operation of gateway and the controllers in ADAP-KOOL®

refrigerating systems is performed with control panel type AKA 21

or with system software type AKM (installed on PC).

The control panel is connected to the two-core data

communication cable at any random point. After that, all settings

and adjustments pertaining to the day-to-day operation of the

system can be made.

Cold rooms and refrigeration appliances are regulated by AKC 72A

and AKC 114-116.

A gateway type AKA 245 is attached to the data communication

system and connected to a modem or printer.

If a PC is to be used in the actual system, one more gateway will

have to be connected. This gateway may also be an AKA 245, but

if the gateway is required for simple operation of the system, the

smaller type AKA 241 may be employed.

The printer can make printouts of all alarm reports registered on

the refrigeration system by the AKC controllers.

If the alarms are to be transferred to the security centre or to the

refrigeration company’s PC or printer, it must take place via the

modem connection.

Log data can be collected from all connected controllers. This data

may then be picked up by a PC and displayed.

Log data can also be stored as documentation for correct tempera-

ture behaviour (demands to temperature registration on the part

of the authorities).

It is also possible to communicate with other control lers via the LonWorks output. Primarily controllers

from the EKC 201, 300, 400, 500 or AK 2 series.
