to enable dry run alarm
with auto-learning mode. In this mode,
the SW2 will learn the real consump-

without auto-learning mode. In this
case, when the pump consumes a 40%

the dry run alarm will appear.

Remark 2:
Basic SWITCHMATIC 1/3 can only detect dry-running
operation through the minimum pressure. This means that
plumber must determine the water column of the installa-
tion, the start pressure of the pump and place the minimum
pressure below the start pressure.
It can also occur that pumping system is running out of its
curve so that the pump is unable to provide the minimum
pressure because the flow requirement is excessive. In this
case SWITCHMATIC 1/3 would activate a false dry-running
alarm.
If these concepts are not clear, it is preferable not configure
this protection or install the SWITCHMATIC 2 with accurate
and easy setting of dry-run detection.
Remark 3:
By choosing “no” (normally open) it will operate as an auxi-
liary pressure control element in the suction of the pump. It
will restart when the suction pressure reaches the configu
-
red PStart.

- PStop:

PStart:

11. SYNCHRONISATION (
ONLY FOR SWITCHMATIC 2
)
SWITCHMATIC 2 can be synchronized to another unit SWITCH-
MATIC 2 managing and protecting 2 pumps operating in cascade
with alternated starting sequence. Next steps must be followed:
1. GO TO ADVANCED MENU: + +
- In
step 2
: select E01 in a unit (this one will be the master) and
select E02 in the other unit (this one will be the slave).
- In
step 3
: select
identical
parameters of gap between pressu-
res d.XX. This is the difference beetween the starting pressure
of main and auxiliary pumps, it is also the difference beetween
stop pressures of both pumps.
2. Press repeatedly until exit the ADVANCED MENU.
3. SET
identical
cut-in and cut-out pressures in both units.
To optimize the synchronization, the minimum difference
between the start and stop pressures must be at least 1 bar.
4. Press in order to disable the units. Is displayed “OFF”.
5. Press
again in both units in order to activate the synchroni-
zation.
Remark 4: after 10 cycles the unit configured E01 will display
pressure and the unit configured E02 will display current in
Amps.
