7 Operation
Operating the product is limited to its regular monitoring:
• The green LED is on.
• The red LED is off.
• The audible alarm is off.
7.1 Alarm condition
In the case of a leak alarm, the red LED is permanently illuminated and the
audible alarm is activated. The relay is energised.
The alarm signal can be transmitted to additional equipment via the relay out-
put.
In the case of products with an EnOcean® wireless module, the product
sends a message to the AFRISOhome gateway. The user receives a mes-
sage from the AFRISO app that a leak has been detected.
7.2 Determining the tank with the leak if several tanks are connected
to one leak detector
1. Close all shut-off valves of the two distributors (pressure line and meas-
uring line).
2. Connect a pressure measuring instrument to the lateral connection of the
red measuring valve.
3. Open the two shut-off valves of the first tank (pressure line and measuring
line).
4. If the pressure measuring instrument does not indicate a pressure drop,
close the two shut-off valves of the first tank and open the two shut-off
valves of the next tank (pressure line and measuring line).
5. If the pressure measuring instrument does not indicate a pressure drop,
continue with the same test at all further tanks until you have located the
defective tank.
6. After the cause for the alarm has been properly removed, open all shut-
off valves of the connected tanks.
