SYNCHRONISATION

ONLY FOR SWITCHMATIC 2

SWITCHMATIC 2 can be synchronized to another unit SWITCHMATIC 2
managing and protecting 2 pumps operating in cascade with alternated
starting sequence. Next steps must be followed:
1. SET identical cutin and cutout pressures in both units.
2. 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 diff erential d.XX.
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 synchronization.
Remark 3: after 10 cycles the unit confi gured E01 will display pressu
re and the unit confi gured E02 will display current in Amps.
ACCURATE DRYRUNNING DETECTION diagram C
In the SWITCHMATIC 2 model it is enough to set the rated current of the
pump in order to activate the overcurrent 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 hydropneumatic tank
is infl ated to the required pressure.
2. Go to the ADVANCED MENU:
 Press simultaneously + + during 5 seconds.
 Press 7 consecutive times to accept and go to the next step until
reaching dr0.
 Using , set dr1.
3. Press and close all the valves.
4. The pump will start, will fi ll the installation and will stop at the cutout
pressure.
5. Now, SWITCHMATIC 2 knows the current consumption 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 and until the display show
0.0 fl ashing.
3. 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 fl ashes
with a fi gure.
3. Adjust the pressure with the arrows pushbuttons to get the pressure
desired.
4. Press to validate.
Remark 4: pressure sensor decalibration should not be a normal
event. If it is frequently repeated contact the technical service.

DRYRUNNING
Only for
SWITCHMATIC 2
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 fi rst 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 fi nd
a defi nitive alarm.

OVERLOAD
Overcurrent alarm is activated when the
nominal pump current is exceeded.
4 automatic reset attempts prior to the

This alarm can be unabled or disabled in
the BASIC MENU. The alarm is activated
when 3 consecutive cycles occur in a range
lower than the set time. This alarm does
not stop the normal operation but are
added 5 seconds to the start delay in order
to protect the electric pump.
To reset the normal operation press ENTER.
