4. SAFETY DEVICES
Shearing prevention system: realized by means of a NO micro-switch in conformity with
the European standard. It stops the mixer motor when the tank cover is opened;
Motor reliability of service: realized by means of overload relays, which can be manually
reset. They protect the machine motors against overloads and the pushbuttons STOP and
TER contemporarily light up. An acoustic signal (beep) is issued every 10 seconds. To
reach the overload relay, press the reset pushbutton once or twice at the most to avoid
burning the motor winding.
Auxiliary circuit supply safety system (24 V): realized by means of an insulating
transformer according to the European Standards in force. In case of trouble it prevents
the primary circuit voltage from being present on the auxiliary elements (probes, logic unit,
solenoid valves, etc.).
Protection against auxiliary equipment short-circuit: realized by means of modular
magneto-thermal circuit-breakers, that trip in case of short-circuit on the logic unit or on the
auxiliary power supply.
The cut-off function is automatically restored after removing the problem making the safety
system trip.
Glycol circuit alarm: when the machine is in STOP position and the FLU led is lighted up,
the glycol circuit is in trouble (opened water valve and blocked pump).
Fluid level alarm: when the FLU led blinks the level of fluid has reached the bottom and it
is necessary to check the circuit.
Safety thermostat alarm: when the machine is in STOP position and the TER led is
lighted up, the fluid safety thermostat or one of the motor protection has tripped.
Temperature probe alarm: when the machine is in STOP position and the TEM led is
lighted up, the temperature probe circuit does not correctly work.
In any case the machine carries out a series of tests during production:
Logic unit self-reset in case of lack of power supply
• Diagnosis of control panel flashing signal lights: all leds present on the panel light up for
10 seconds at each current reset and show the operator their functions. Press any key
to exit this function.
• Automatic reset of the previously set-up function.
Logic unit self-diagnosis (watch-dog)

Followed by led FLU (fluid alarm) blinking and by a
beep from the buzzer every 10” if the glycol level is
low.
Followed by led FLU (fluid alarm) lighted up and by
a beep from the buzzer every 10” if the glycol
pressure is low. It can be caused by the opening of
glycol pressure switch.
Followed by led TER blinking and a beep from the
buzzer every 10” in case a motor overload relay has
tripped, or the thermostat has intervened due to
glycol temperature over 110°C (230°F).
At each machine start-up, the microprocessor
checks the data in EPROM memory. If they are not
correct, the display visualizes the writing EPO
followed by a beep from the buzzer every 10”.
If memory is not recognized, during operation the
display visualized the writing EPI followed by a beep
from the buzzer every 10”.
If during operation voltage is too low, the display
visualizes the writing LI followed by a beep from the
buzzer every 10”.
If during operation the output control module breaks
down or it is not recognized, the display visualizes
the writing OUT followed by a beep from the buzzer
every 10”.
Make sure that the cover
is closed and correctly
positioned.

Temperature probe alarm
Unlike the above-mentioned messages, the temperature probe alarm is a message
composed as follows:
P=PROBE 1= TANK 2=FLUID O=OPEN (open) C=CLOSED (short-circ.)
For example, if the display visualizes message P10 followed by led TEM (temperature
alarm) blinking and by a beep from the buzzer every 10”, it means that the tank probe is
broken down. In this case send for a technician.
