Chap. 7 - VARIATION OF OPERATIONAL PARAMETERS
- units without pilot pump
Every time that voltage is cut from the switchboard, the order of original starting is restored. Pump n.1 shall be
operated upon first on first automatic starting, then pump n. 2 etc.. After each cycle (stopping of all pumps) the pump
following the last is operated upon. Every time that a pressure switch is opened the microprocessor selects the pump
which is set and every time that a pressure switch opens, the first initialized pump stops.
- units with pilot pump
The pilot pump starts first; it is stopped after the starting of the first service pump and is started again after the last
service pump.
If the cyclical reversal has been disabled (see chap.7 -variation of operational parameters) the pumps are started and
stopped in sequence.
A) CONFIGURATION AND INSERTION OF OPERATIONAL PARAMETERS
Check that the control level is inserted in the tank of first gathering filled with water or that this is jumped.
WARNING
The calibration values of the pressure switch must be between the
minimum and maximum working pressure levels foreseen for the
pump used in the unit and reported in the plate applied to the
pumps themselves.
Bring the general switch of the switchboard to position I (ON)

With keys (16) or (17) it is possible to set YES or NO.
YES
it means that at the end of every working cycle it will change the pump which initializes first
NO
it means that the function of pump reversal will stay locked
