SYNCHRONISATION ( ONLY FOR SWITCHMATIC 2 )
T-Kit Switchmatic 2 can be synchronized to another unit T-
Kit Switchmatic 2 managing and protecting 2 pumps ope-
rating in cascade with alternated starting sequence. Next
steps must be followed:
1. SET identical cut-in and cut-out pressures in both units.
To optimize the synchronization, the minimum diffe-
rence between the start and stop pressures must be at
least 1 bar.
2. GO TO ADVANCED MENU:
- In step 2: select E01 in a unit (this one will be the mas-
ter) and select E02 in the other unit (this one will be the
slave).
- In step 3: select identical parameters of gap 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.
3. Press repeatedly until exit the ADVANCED MENU.
4. Press in order to disable the units. Is displayed "OFF".
5. Press again in both units in order to activate the syn-
chronization.
Remark 3: after 10 cycles the unit configured E01 will
display pressure and the unit configured E02 will dis-
play current in Amps.
ACCURATE DRY-RUNNING DETECTION
In the T-Kit Switchmatic 2 model it is enough to set the
rated current of the pump in order to activate the overcu-
rrent and dry-running protection. However, the accuracy of
dry-running detection can be improved by the activation
of dr1 parameter in the ADVANCED MENU. The following
steps must be followed:
1. Drain the hydraulic installation and verify that the hy-
dropneumatic tank is inflated to the required pressure.
2. Go to the ADVANCED MENU:
- Press simultaneously
- Press 7 consecutive times to accept and go to
the next step until reaching dr0.
- Using , set dr1.
3. Press in order to start the self-learning function.
4. Open a valve/tap of the hydraullic net and keep water
circulation for 15 seconds. Then close all the valves/taps.
The pump will start, will fill the installation and will
stop at the cut-out pressure.
5. Now, T-Kit Switchmatic 2 knows the current consump-
tion curve of the pump.
If you install a new pump this process should be repeated.
If you enter the CURRENT INTENSITY MENU by pressing
for 3 seconds all this process is invalidated because is
predominant the rated current manually introduced.

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:
ZERO REGULATION
1. Open the taps living the hydraulic net without pressure.
2. Press simultaneously the buttons
display show 0.0 flashing.
3. Press to validate.
FULL SCALE
1. Start the pump until cut-out of the pressure switch.
2. Press simultaneously the buttons
play flashes with a figure.
3. Adjust the pressure with the arrows push-buttons to get
the pressure desired.
4. Press to validate.
Remark 5: pressure sensor decalibration should not be
a normal event. If it is frequently repeated contact the
technical service.
