6.2.5 PERIODIC AUTO TEST-RUN
In systems subject to long periods of inactivity it is recommended to perform a periodic automatic test
(auto test-run) with the aim of checking the performances of the group.
In any case the autotest cannot replace programmed maintenance, which must be carried out
periodically. A weekly interval is recommended.
To start the test request the board's internal clock may be used, or an external command. When autotest
is enabled, the alarm relay is automatically configured to control the solenoid valve.
It is also necessary to ensure that the parameter CONFIG. IN. AUX3 in the DIGITAL IN/OUT MENU is set as
CONV.L.SWITCH (Minimun Pressure Switch).
