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. 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.
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 diffe-
rence 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 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.
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.

SYSTEM REACTION
When is detected a dry-run
operation the pump is auto-
matically stopped. By mean of
ENTER the normal operation
can be manually restored.
After the activation of the
dry-running alarm if the
Automatic system reset (ART)
is enabled, a first attempt at 5
minutes and then an attempt
every 30 minutes for 24 hours
is performed in order to
restore the normal operation.
This alarm can also be reset
manually with the ENTER
push-button. If the alarm
persists after 24 h we find a
definitive alarm.
Is displayed during normal
operation if the pressure is
below the minimum pressure
(Px.x) - previously set - during
a period (txx) - also previously
set - in the ADVANCED
MENU.
If at any time the pressure
exceeds the minimum pres-
sure, the operation is restored
automatically and the alarm is
cleared.
Normal operation can also be
restored manually by pressing
ENTER.
Overcurrent alarm is activa-
ted when the nominal pump
current is exceeded.
4 automatic reset attempts
prior to the final alarm are
performed.
During the attempts display
will show current.
Normal operation can also be
restored manually by pressing
ENTER.
This alarm can be unabled or
activated in the BASIC MENU.
The alarm is activated when 3
consecutive cycles occur in a
range lower than the set time
(between cycles).
If it has been activated rc1,
this alarm does not stop the
normal operation but are
added 5 seconds to the start
delay in order to protect the
electric pump.
If it has been activated rc2,
the pump is stopped.
To RESET the normal opera-
tion press ENTER.
