AKC 25H1
The following messages can be connected to a "DI input" at your option. This is done with the
"configuration of inputs" setting.
For each individual DI input you may furthermore define the importance of the alarm:
DI( ) Dest [ 1, 2, 0 ]
Air flow switch
Compr. no( ) current cut out
Compr. no( ) disch temp cut out
Comp. no( ) disch press. cut out
Compr. no( ) motor prot. cut out
Compr. no( ) not in auto
Comp. no( ) safety cut out
Comp. no( ) oil press. cut out
Cond. no( ) safety cut out
Condensate pump fault
Current fault
Flow pump fault
High condensate level
Liquid flow switch
Low liquid level
Phase fault
Refrigerant leak
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".
