  • Page 3: System Survey

    System survey Principle 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.

  • Page 9: Manual Change-Over Of Alarm Routing

    When a battery is replaced, make sure that the supply voltage is not removed from the gateway. If the bat- tery and supply voltage are both removed at the same time, the clock setup, log setup, collected log data, master control setups and possibly EKC installation data will all be lost. AKA 245 Manual RS8DT102 © Danfoss 09/2004...

  • Page 10: Pc, Modem Or Server Connection

    In order not to destroy the output on the PC, the modem or the server the following precautions must be taken: - Establish the correct earth connection on AKA 245 - Interrupt the supply voltage to the gateway and to the PC / the Modem / the server, when the cable is mounted and dismounted.
  • Page 11 Use a standard modem cable. Supply voltage to the modem must be connected, as illustrated (via DO1). This will permit AKA 245 to reset the modem. Also, the modem will be switched on and its start controlled, when AKA 245 is switched on.

    All controller alarms will now be transmitted to the master gateway. b) If you select “Auto setup” = “No setup” (the factory setting in AKA 245), the master gateway will not change the setting in the controllers. Chan ges can only be made on each individual AKC controller.
  • Page 14 Alarms from EKC controllers will also be registered by AKA 245, but if the data connection between the EKC controllers and the gateway is interrupted, only an active alarm, if any, will be present when the connection is reestablished. In other words, all alarms occurring during the period without data com- munication will not be registered.
  • Page 15 Alarm list in AKA 245 The alarm list can be displayed from system software type AKM or from control panel type AKA 21. From AKM: via the “History" - "AKA Alarm List” menu. From AKA 21, as follows: - select the master gateway (address = 125) - push key “F1”...

    It is recommended that only one of the two options be used on the same system. (When AKA 245 is delivered ex stock, the alarm table is not active). Appendix B contains a description of repeat routines for alarm transmissions when calls are not successful.

  • Page 17: Printer Function

    Alarm printout from PC A printer connected to AKA 245 can print an alarm report from a PC connected to DANBUSS. To use this function, a datagram of a special format has to be transmitted to the gateway. This means that it is in practice the application software in the PC and the internal software in the gateway that use this facility.

  • Page 18: Data Collection In Master Gate Way

    The master gateway constantly controls all log setups via a simple check-sum calculation. If there is an error, the log in question will be deleted. An alarm will now be given with information about the log number. Manual RS8DT102 © Danfoss 09/2004 AKA 245...

  • Page 19: Modem Connection

    AKA 245 can act as connecting link between DANBUSS and a modem. (DANFOSS can provide information about other modem types that can be used with the gateway) By connecting the supply to the modem via a relay switch (DO 1) on the gateway, the gateway will be able to reset the modem.

  • Page 20: Aka Override Function

    AKA override function AKA 245 contains a function capable of reading values from a given function in a given controller on Data communication. The gateway will treat the information and then set the values in other selected controllers in the system. Each individual controller will subsequently carry out the given function. You can max.

  • Page 33: Appendix

    It is important that all units on the same network have the same network number. Example: The example shows a system consisting of two networks. 1) PC connected to AKA 245 2) AKA 245 and AKC controller 1:1 means network number 1 with address 1.
  • Page 34 An address is indicated for the next receiver of the datagram. This may either be the fi nal receiver for whom the datagram was intended, or it may be the address of another AKA 245, say, a modem gateway that has to re-transmit the datagram. If “Port No. ” = 2 (RS 232): At connection to a PC no address has to be entered, as only one PC can be connected.
  • Page 35 AKA 245 The PC wants to send a message to the AKC with system address 2:1. The datagram is fi rst sent to AKA 245 who checks its router table to see where the datagram has to be routed. As the controller is on the same network as the master gateway, it will transmit directly to the control- ler (a router line will not be required).
  • Page 36 Make sure that you have an easily legible list of addresses and network numbers on all relevant gateways and PC’s before establish ment of router lines is commenced! Don’t forget that messages are also returned in the system.! Manual RS8DT102 © Danfoss 09/2004 AKA 245...

    Appendix C Data collection takes up this much room When a log is established in an AKA 245 master gateway, room is set aside for data. Just how much room is reserved is determined by various parameters. The amount of room that will be reserved can be seen when new logs are established.
