Alarms and messages
22
In connection with the controller's functions there are a number of alarms and messages that
become visible in case of an error or wrong operation.
Distinction is made between important and not quite so important messages. The importance
of certain types of information has been established, while others may be changed, as
required (this change can only be performed, when a PC has been connected to the system,
and settings have to be made in all relevant controllers).
The importance is indicated with the following settings:
1. "Alarms"
This is important information from the controller.
- The controller's alarm output is activated
- The information is transmitted on the DANBUSS network together with status value 1
- If a gateway type AKA 243/244 is connected which is defined as master, its relay output
DO2 will be activated for two minutes.
- Later, when the alarm is cancelled, the same information will be repeated, but this time
with status value 0.
2. "Messages"
This is less important information from the controller.
- The information is transmitted on the DANBUSS network together with status value 2
- Later, when the alarm is cancelled, the same information will be repeated, but this time
with status value 0
3. "Alarms"
As "1", but the DO2 output on a master gateway will not be activated.
0. "Suppressed information"
This information stops at the controller. It is transmitted nowhere.

Information from the controller
Below, the information is shown together with the importance of it. The information is shown in
brackets "[ ]". (The factory setting is shown in bold type).
Sx Error( ) [ 1, 2, 3, 0 ]
The sensor is interrupted, shortcircuited or not mounted. Change-over to emergency
procedure. Depending on the sensor for which an error has been reported, the control-
ler will select a procedure (see section on "failsafe functions").
AKS 32 Error [ 1, 2, 3, 0 ]
The sensor is interrupted, shortcircuited or not mounted.
Change-over to emergency procedure (see section on "failsafe functions").
High air Temp( ) [ 1, 2, 3, 0 ]
Too high air temperature
The air temperature measured with an alarm sensor has exceded the defined upper
limit for the alarm time delay. If the air temperature fluctuates back to the normal
regulation range, the alarm output is reset.
