Remark 3:
By choosing "no" (normally open) it will operate as an auxiliary
pressure control element in the suction of the pump. It will restart
when the suction pressure reaches the configured PStart.
Example:
- PStop: 0,9 bar
- PStart: 1,2 bar
11. SYNCHRONISATION
SWITCHMATIC 2T can be synchronized to another unit SWITCHMATIC 2T
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 pressures d.XX.
This is the difference beetween the starting pressure of main and au-
xiliary 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 synchronization.
Remark 4: after 10 cycles the unit configured E01 will display pressu-
re and the unit configured E02 will display current in Amps.

12. PRESSURE SENSOR CALIBRATION
In case of wrong lecture of the pressure sensor it can be adjusted again.
For the pressure sensor calibration is necessary to have a pressure gauge
in the installation. Proceed following next steps:
