5.1 Fault prompts

5.1.1. «ALARM» prompt
The «ALARM « prompt will be displayed during a dosing operation (irrespective of the dosing
option) if one or both valves are open and if the controller detects a no flow condition. The
delay before triggering the alarm is set within the Calibration menu. (see § 4.3.6)
The «ALARM» prompt will be displayed at the end of a dosing operation (irrespective of the
dosing option), if one or both valves are closed and if the controller detects a flow (after
the delay before alarm triggering has elapsed).
Note: The alarm delay must take account of any selected overflow correction. (the volume
which continues to flow after the closure of the valve).
5.1.2.«[T] ERROR» prompt
This error prompt only occurs in the «EXT.[T]» option. It is displayed during a dosing
operation if the duration of the pulse is greater than 300 seconds, or if it is greater than the
duration necessary to deliver the relevant volume.
It will also appear if the volume to deliver is greater than 100000 (l, m 3 , etc.) or if the volume
3
delivered has reached 100000 (l, m , etc.) and when the pulse has not been switched off.
5.1.3. «ERROR» prompt
The «ERROR» prompt flashes then the calibration parameter values have been lost. Press
the ENTER key, the Main Menu is displayed, but the unit is set in the basic default
configuration (see § 5.3). It is necessary to re-program the driver unit. If the display of this
