Description
Choice of the full-scale value of the installed
sensor.
Rated pump pressure with the circuit at flow-rate
zero.
Mean pressure to be maintained in the system.
The increase or decrease of the SetPoint pressure
modifies all the start and stop values of each pump
making them higher or lower (see graph ref.18).
Pressure difference allowed between the start and
stop of the PILOT pump or P1 SUPPLY pump.
Lower pressure differential for starting between the
first pump and the second pump, between the
second and the third, between the third and the
fourth (whether they are pilot, supply or backup).
Upper pressure differential for stopping between the
first pump and the second pump, between the second
and the third, between the third and the fourth
(whether they are pilot, supply or backup).
Delay time at start of the PILOT pump or P1
SUPPLY pump, when the pressure is lower than the
parameter set in Dif.Start/Stop P1
Delay time at start of the SUPPLY pumps P2, P3,
P4 when the pressure is lower than the parameter
set in Dif.Start P2P3P4.
Choice of the minimum running time of the PILOT
pump or SUPPLY pump P1.
Choice of the minimum running time of the
SUPPLY pumps P2, P3, P4 or of the BACKUP
pump.
Choice of the minimum time within which the second
start, after the first, is NOT allowed for the PILOT
pump or the SUPPLY pump P1. Any intervention
keeps the pump blocked until the end of the set time.
In this interval of time the pump start delay is
indicated with the message WAIT.
Choice of the minimum time within which the second
start, after the first, is NOT allowed for the SUPPLY
pump P2, P3, P4 or the BACKUP pump. Any
intervention keeps the pump blocked until the end of
the set time. In this interval of time the pump start
delay is indicated with the message WAIT.
Pressure value for which the control unit goes into
alarm status for overpressure. The control unit blocks
the system if the pressure remains above the set value
for more than 5 seconds. As soon as the pressure
returns to normal, the system is enabled (only after 5
seconds).
The protection is indicated in remote mode.
