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.
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. Press ENTER to disconnect the device. It ill be displayed OFF.
2. Open the taps living the hydraulic net without pressure.
3. Press simultaneously the buttons and until the display show 0.0
flashing.
4. Press to validate.
FULL SCALE
1. Start the pump until cut-out of the pressure switch.
2. Press simultaneously the buttons and
till the display flashes with
a figure.
3. Adjust the pressure with the arrows push-buttons to get the pressure de-
sired.
4. Press to validate.
Remark 5: pressure sensor decalibration should not be a normal
event. If it is frequently repeated contact the technical service.
WARNINGS AND ALARMS
COD. DESCRIPTION SYSTEM REACTION
A01
O
DRY-RUNNING
When is detected a dry-run operation the
pump is automatically stopped. By mean
of ENTER the normal operation can be
manually restored.
( ( O ) )
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-but-
ton. If the alarm persists after 24 h we find
a definitive alarm.
A11 O
DRY-RUNNING
(BY MINIMUM
PRESSURE)
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 ADVAN-
CED MENU.
If at any time the pressure exceeds the mi-
nimum pressure, the operation is restored
automatically and the alarm is cleared.
Normal operation can also be restored
manually by pressing ENTER.
A02
O
OVERLOAD
Overcurrent alarm is activated 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.
( ( O ) )
A04 (((O))) FAST CYCLING
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 cycle and
cycle).
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 operation press
ENTER.
A05 O

SURE TRANS-
MITTER

A08
O
OVERVOLTAGE
Overvoltage alarm is activated when the
power supply voltage is exceeded.
4 automatic reset attempts prior to the
final alarm are performed.
During the attempts display will show .
Normal operation can also be restored
manually by pressing ENTER.
( ( O ) )
A09
O
UNDERVOLTAGE
Undervoltage alarm is activated when
the power supply voltageis under the
minimum.
4 automatic reset attempts prior to the
final alarm are performed.
During the attempts display will show .
Normal operation can also be restored
manually by pressing ENTER.
