Operating and functions
10.7.25 Configuring the relay output DO3 to control an auxiliary
valve
• Connect the auxiliary valve (installed into the pipe with low flow rate) to the relay output DO3. See
chap. 8.14.
• The time delay before opening the auxiliary valve is the same as the time delay before opening the main
valve.
• If no auxiliary valve is necessary, enter a filling rate of 100 in the settings of the relay output DO2.
If the filling rate associated to the relay output DO2 is < 100, the relay output DO3 is automatically configured to
control the auxiliary valve that completes the filling up to 100.

10.7.26 Configuring the transistor output DO4 to transmit the
device state and activating / deactivating the generation of
a 10 Hz frequency when an error message is generated by
the device
The transistor output DO4 can be configured to transmit the device state to a LED or a remote instrument (PLC
for example).
If, furthermore, the device signals an operating error (see chap. 11.3.2), the transistor output DO4 can be con-
figured to generate a 10 Hz-frequency.
The following states are transmitted:
State of the device State of the the transistor output DO4
No dosing being done OFF
Dosing being done ON
Dosing interrupted 1 Hz-frequency
