Operating and functions
10.7.17 Activating / deactivating the generation of alarms for
problems occurring at the end of a dosing
When the following 3 criteria are fulfilled the dosing is finished:
• no flow rate measured in the pipe,
• the valves are closed,
• and the quantity has entirely been dosed.
If a flow rate is measured in the pipe whereas the valves should be closed (once the dosing is finished or when a
dosing has been interrupted), an alarm can be generated.
When an alarm is generated, the device stops the process:
• the valves connected to the relay outputs DO2 and DO3 are closed,
• the device state LED becomes orange and flashes fast,
• a 3,5 Hz-frequency is generated on the transistor output DO4 if it is configured to transmit the state of the
device (see chap. 10.7.26),
• the outputs configured with the function "ALARM" are switched (see chap. 10.7.19),
• the message "ALARM" is displayed.
→ Activate or deactivate the generation of an alarm when a flow rate is
measured in the pipe whereas the valves are closed.
→ Confirm.

→ If the generation of alarms has been activated, enter the duration the
problem must be present (value between 1 and 200 s) before gener-
