Description
Thermal alarms with block of the respective
pumps and remote signalling.
Indicated with: AL8PI, AL8P2, AL8PS.
3 = 4P.
4 supply pumps
Functions:
All the supply pumps work on system pressures
set in the reference SetPoint and Differentials.
Rotation of the starting order of the supply pumps
(the first pump to start is the first pump to stop).
Weekly anti-blocking test of the supply pumps
with 15 sec. forced operation each (if parameter 5
is enabled). Indicated with: P1TEST, P2TEST,
P3TEST, P4TEST.
Thermal alarms with block of the respective
pumps and remote signalling.
Indicated with: AL8P1, AL8P2, AL8P3, AL8P4.
4 = 3P. + 1P.S.),
3 supply pumps
+ 1 backup pump
Functions:
All the supply pumps work on system pressures
set in the reference SetPoint and Differentials.
Rotation of the starting order of the supply pumps
(the first pump to start is the first pump to stop).
Weekly anti-blocking test of only the backup
pump (if parameter 5 is enabled). The backup
pump starts up according to the setting in
parameter 6 (anti-blocking time) and remains
enabled to operate from a minimum of 1 min. to a
maximum of 30 min. The message PS.TEST will
appear on the display.
Thermal alarms with block of the respective
pumps and remote signalling.
Indicated with: AL8P1, AL8P2, AL8P3, AL8PS.
1 : Relative pressure transmitter
2 : Differential pressure transmitter
Choice of the number of supply pumps that make
up the system:
max two for system type 2
max three for system type 1
max four for system type 3
Choice whether to exclude or insert the pump anti-
blocking test cycle.
Setting of the pump stopped time after which the
pump anti-blocking test must be carried out.
