Example:
On the bus are 3 control modules and 1 common alarm module. The first control module is in alarm 1 status,
the second control module is in alarm 2 status, and the third control module submits system failure. All LEDs
and relays on the common alarm module will be activated, the analog output will generate 16 mA, and the
display will show „COMMON ALARM 2“.
Alarm relays configuration
In this menu you can set the parameters of alarm relays A1 and A2:
1.
Latching (HOLD) or non-latching (AUTO RESET)
2.
Coil active (ACTIVE) or passive (PASSIVE) in case of an alarm.
As long as an alarm is submitted via bus, the relevant LEDs are on and the corresponding relays are switched.
If an alarm threshold is exceeded, the LEDs A1 and A2 are on, and the relays switch. Alarms can be reset,
provided the reason for the alarm has disappeared. If the alarms have been programmed to be latching, you
have to push reset button or use the external reset to delete the alarm message. For additional information
see chapter 4.5.1.
