8.3. Operating levels of the device
The device has two operating levels: the Process level and the Configuration level.
The Process level makes it possible:
• to read the flow rate measured by the device and the value of the
totalizers, the main and the daily one.
• to reset the daily totalizer.
• to access the Configuration level.
The Configuration level makes it possible to set the device
parameters.

8.6.2. Choosing the flow rate units, the number of decimals and the units of the totalizers
The max. flow rate that can be displayed depends on the
number of decimals chosen:
• 9999 if the number of decimals = 0,
• 999,9 if the number of decimals = 1,
• 99,99 if the number of decimals = 2,
• 9,999 if the number of decimals = 3.
The maximal volume that can be displayed by the totalizers
depends on the unit of the chosen volume:
• 9 999 999 if the chosen volume unit is "litre",
3
• 999 999 if the chosen volume unit is "m
The "UNIT" parameter makes it possible to choose:
• the flow rate units.
• a fixed number of decimals (choose 0, 1, 2 or 3) to display the
flow rate in the Process level.
• the volume units of the totalizers if the unit previously chosen is in

9. MAINTENANCE AND TROUBLESHOOTING
9.1. Safety instructions
danger
Risk of injury due to high pressure in the installation.
• Stop the circulation of fluid, cut off the pressure and drain the
pipe before loosening the process connections.
Risk of injury due to electrical voltage.
• Shut down and isolate the electrical power source before carrying out work on the system.
• Put the power switch to OFF before carrying out work on the
device.
• Observe all applicable accident protection and safety regulations for electrical equipment.
Risk of injury due to high fluid temperatures.
• Use safety gloves to handle the device.
• Stop the circulation of fluid and drain the pipe before loosening
the process connections.
Risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention and
safety relating to the use of aggressive fluids.
