If the pressure switch is activated in automatic mode
and not during Auto-test, the following happens:
- If the pumps are running they will not be
stopped and alarm A38 will be shown.
- If the pumps are not running they will not start
and alarm A38 will be shown. If there is a pres-
sure drop, however, they will be switched on
and alarm A38 continues to be shown.
If the minimum pressure is activated during the
Auto-test, see section 8.1.

Auto-test RUN
8.1
Using the Auto-test function, the pumps can be
switched ON when they have been OFF for a long
time.
The pumps are switched ON by the clock or by an
external digital contact (c24).
NOTICE:
The following components have to be used:
•
Solenoid valve: it is required to drain the water
during the test.
•
Membrane pressure switch or equivalent de-
vice. It is used to check the performance of the
pump to prevent its value from dropping too
low. It is connected to D IN PROGR of the Q-
SMART control panel (refer to figures
•
Q-SMART-6FVC MODULE, electronic card
relay voltage-free contacts (refer to figures
and 9)
How to start the auto-test: activation by clock
(c24=1)
If the pumps are running, the auto-test is put on
hold and this text is shown on the display in blink-
ing mode:
