Triggering an emergency shut-off

On the screen below, digital input 1 on valve V1L triggers an alarm.

As a result, the gas supply system has been shut down according to the set logic.

When an alarm is triggered, the date and time as well as the name of the alarm are recorded.

The entries of the resolved alarms must be cancelled to be able to resume operation. They can only be cancelled if access is enabled with a level 1 or 2 password.

After the error has been rectified and the alarm has been cleared, the gas supply system can be re-commissioned. See "Putting the valve in standby mode".

All alarms are stored in the alarm history and can be retrieved via the configuration menu. Each alarm is automatically cleared from the history after 3 months.
