MOTOR PUMP IDENTIFICATION PLATE
WARNING
• Should the identication plate deteriorate during use, contact the Manufacturer or a
Skilled Technician
to
have it restored.
e identication plate(12) shows the motor pump model, the serial number, the year of manufacture and the
main electrical and mechanical specications (max rotation speed, max pressure, weight, power supply voltage,
input, etc.). It is located on the electric motor casing or on the power box.
SAFETY DEVICES
WARNING
If the machine in which the motor pump is integrated features a safety valve, i.e., a max. pressure valve, suitably
calibrated, which discharges excess pressure in case of a fault in the high-pressure circuit, in the event of the
safety valve tripping frequently, immediately stop using the machine in which the motor pump is integrated
and have it checked by a
Skilled Technician
.
a) Pressure unloader/regulation valve.
is valve is suitably set by the Manufacturer and allows regulating the operating pressure and permits the
pumped uid to ow back towards the bypass duct, thus preventing the accumulation of dangerous pressures
when the delivery line is closed or when attempts are made to set pressure values above the maximum ones
allowed.
WARNING
e pressure unloader/regulation valve is set either by the motor pump Manufacturer or by that of the machine
in which the motor pump is integrated.
Never try and adjust the pressure unloader/regulation valve to
alter the setting: only operate on this by means of the knob(2).
b)
ermal or ampere cut-out protection device (only motor pumps with Total Stop).
is device stops motor pump operation in the event of overheating of the electric motor or excessive power
absorption respectively.
In case of tripping, proceed as follows,
keeping to the indications shown in the manual of the machine in
which the motor pump is integrated:
stop the machine and remove the plug from the power socket;
release any residual pressure in the high-pressure circuit;
wait 10÷15 minutes for the motor pump to cool down;
make sure the instructions have been followed in the paragraph
ChECkING AND CONNECTING UP TO ThE POWER
SUPPLY
, with special reference to any extension used;
t the plug back in the socket and repeat the start procedure.
WARNING
In case these safety devices trip frequently, do not use the motor pump (and therefore the machine in which it
is integrated) without rst having it checked by a
Skilled Technician
.
INTENDED USE
WARNING
e motor pump must not be run by itself. It is only meant to be integrated in a machine.
e motor pump must be integrated in machines used for the following purposes:
