Switching on the instrument
•
Place the agitator on a stable surface and connect the power cable.
•
Switch on the instrument.
•
The instrument starts a short self-diagnosis process.
•
When the initialisation is finished, the "set" icon is displayed and at the same time the value setting area flashes
to indicate the possibility of setting the speed value.
•
Turn the SPEED knob to set the stirring speed.
•
Pressing the SPEED knob the LCD display stops flashing and the instrument starts to shake.
•
Press the speed knob again, the LCD display flashes and the parameters can be changed again.
Overload protection
The rod agitator operates continuously, therefore in the event that the liquid to be stirred becomes too viscous, i.e. an
overload occurs, the motor power is automatically regulated electronically. When the "torque limit" value is reached,
the overload protection function is started and at the same time the red LED starts flashing to indicate a small
overload.La protezione contro il sovraccarico interviene nei seguenti casi:
•
When the value of the set speed is not suitable for the current average viscosity;
•
When the crankshaft is braked / blocked.
Malfunctions
•
The instrument does not start when the stirring function is started.
o
Check that the power cable is connected.
•
The speed does not reach the set value
o
The set speed value is not sufficient for the viscosity level of the stirred liquid
•
The agitation suddenly stops
o
The overload protection light turns red, the display shows "Er 03", indicating that the current fault is
"overload protection".
o
The overload protection light turns red, the display area shows "Er 04", indicating that the current
fault is "motor protection".
