This Is How The Various Messages Are Tramsmitted; Who Are The Alarm Receivers - Danfoss ADAP-KOOL AKC 114 G Mode D'emploi

24
This is how the various messages are transmitted:
Information is in principle sent twice.
1) An alarm message when the error is discovered.
2) A message about cancellation of the alarm situation, when the error disappears again.
(In connection with a sensor alarm, there may be 10 minutes between the two messages).
This procedure has a different influence on the below-mentioned systems:
Single systems (systems with control panel type AKA 21)
Information can be shown on the screen, when an "E" (error) is observed.
The error message cannot be removed from AKA 21, as long as the cause of the error
has not been removed. When the cause of the error message has been removed, the
error message will remain visible in AKA 21 until it is acknowledged by pushing "Enter".
Network (Systems with PC or gateway with printer and control panel type AKA 21)
Here the information can be transmitted to the PC or the printer. Accompanying this
message is indication whether it is a new error or an earlier error that has been
transmitted. On control panel type AKA 21 only "new" alarms can be seen in this
situation. Old errors that are transmitted cannot be seen.
To use this function, you have to make a setting in the controller. This setting can only
be made from a PC.
The "Auto reset" setting is put in position "ON".
The individual messages will now be sent to the printer or the PC along with a status
which is either 1, 2, 3 or 0.
1 means that it is new and important information (information defined with setting = 1)
2 means that it is new, but not quite so important information (information defined with
setting = 2)
3 means that it is new and important information (information defined with setting = 3)
0 means that the error has been deleted.

Who are the alarm receivers

Single systems
Control panel type AKA 21 will here be the receiver of alarms from the connected units.
- Each controller is given an address, so that the unit is defined in the system. Setting of
the address is performed directly in each controller via a number of switches (cf.
instructions).
Network systems
A defined PC or gateway with printer will here be the receiver of alarms for the con-
nected units.
- Each controller is given an address, so that the unit is defined in the system. Setting of
the address is performed via a number of switches (cf. instructions).
- Each controller is given a system address. A system address consists of a network
number and an address (the address is the same as the one set in in the controller).
The network number will be set of the gateway.
- The addresses of the receivers of all alarms must be set on each controller. There are
two kinds of settings which can only be carried out via the PC.
• The system address of the nearest master gateway which has to retransmit alarms
and messages.
• The system address of the final receiver of alarms and messages.
Alarm output on AKC controllers
The output will only be activated when the setting is [1] and [3] (see above). Activation
will take place for as long as the defect remains active.
The output is a "cut-out function" where the following applies:
No alarm: The relay contact between terminals 20 and 21 is connected.
Alarm: The relay contact between terminals 20 and 21 is interrupted.
