SPECIAL FUNCTION
BOOSTER APPLICATION (parameter bS is se-
lected, see section 5.4.3)
8.1 Auto-test RUN
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 blinking
mode:
tSt
When the pumps are in standby, the auto-test starts
and the test in progress and the pump in use are
shown on the display in blinking mode:
tSt
P1
How to stop the auto-test
The auto-test can be stopped at any time by press-
ing the OK button.
What does the Auto-test Run do?
Auto-test activated by clock time
The Auto-test function involves the following settings
and sequences:
1.
Enabling the function (c24=1)
2.
Setting the day, hour, minutes of the test (h26,
h27, h28).
3.
Setting the programmable digital input D IN
PROGR (c38=1)
4.
Setting the relay of the 6CP Q-SMART MOD-
ULE, c40=9, Command for Auto-test.
5.
Setting the relay of the 6CP Q-SMART MOD-
ULE, c40=10, Auto-test faulty.
54
6.
At the scheduled time, switching ON Pump P1
after the solenoid valve is opened.
7.
Stopping pump P1 after the set time (h29).
8.
Waiting for a minute
9.
Switching ON pump P2.
10. Stopping pump P2 after the set time (h29).
The Auto-test is interrupted in the following condi-
tions:
The membrane pressure switch is activated
(performance of pump is too low). Alarm A24 or
A25 is triggered. The dedicated relay of the 6CP
Q-SMART MODULE will be activated. The
buzzer of the Q-SMART control panel is also ac-
tivated and the set resumes working in automat-
ic mode. Press button (4), figure 1, to silence
the buzzer.
If the pressure or level in the system changes,
the set resumes working in automatic mode.
The Auto-test is postponed.

8.2 LOAD LOSS COMPENSATION (cr14)
7
Sometimes there is a pressure drop in the system
due to losses in the pipes which increase when the
demand for water increases.
To compensate for loss of load, it is possible to ena-
ble a control that supplies pressure proportional to
the load. A direct measurement of the flow is not
taken, but it is assumed that it is proportional to the
number of pumps running.
When each duty pump after the first is started, the
UPPER and LOWER thresholds are increased by
the value indicated by parameter r14. The jockey
pump is excluded.
