A. The machine does not start when I push START and the monitor displays
machine status: wait speed zero for 30" then press +.
1. The limit switch is tripped (should be reset). Manually enter hose meters (ft).
2. Press + key.
3. Press again START.
B. The machine does not start if I press START and alarm 5 is displayed,
i.e. no pressure.
1. The machine is not under pressure, the equipment will start automatically as soon as
it is under pressure.
2. Pressure switch is not connected or it is wrongly connected: check that pressure switch is
connected to pos. 1 and 4.
3. Pressure switch is faulty (change it); in this case it is possible to start the equipment by
connecting the two pressure switch wires.
C. The machine starts very slowly if I press START. After 11 minutes the monitor
displays alarm 4. Set potentiality value is too high, correct it:
1. Press - key to delete alarm from LCD.
2. Hold down Prog key to enter the parameter page.
3. Press Prog up to Potentiality (flashing) value Pt.
4. Press - key and decrease the value, such as 150.
5. Press again Prog key and go back to machine winding status page.
D. While working, the machine sets to security mode and the LCD displays
alarm 4, i.e. Speed fault:
1. A wrong speed is engaged for the type of programme set;
change speed and reprogram.
2. The sensor reading speed does not output the correct value (check for proper
operation).
E. While working, the machine sets to safety mode and the LCD displays
alarm 3, i.e. Litre counter fault.
1. Rain priority programme was enabled and machine is not fitted with litre
counter (change programme).
2. Litre counter is jammed, clear and clean it. Press - key to delete alarm from display and
then press Start to restart the machine.
F. While working, the LCD displays alarm 1, i.e. Battery fault
(battery voltage is below 8 V), it is necessary to charge the battery.
NOTE: The battery shall be charged with correctly set battery charger and for 24 hours.
Battery will IRREPARABLY damage if charged with battery charger set at maximum value.
G. While working, the machine does not settle working speed, i.e., speed continuously increases and
decreases:
1. A program requiring high speed was set (100-200 m/h) and the equipment is set to a low
potentiality value: increase potentiality value. (see pos. C)
H. The machine ends working cycle but the LCD displays alarm 4, i.e. Speed
fault:
1. At work end, the cycle end electric contact was not activated. Press - key to delete the fault
and set the limit switch activation plate.
2. Too high a speed is engaged with respect to the programme set.
At work end, the equipment completely opens the turbine by-pass but speed is higher
than programme set. Press - key to delete the fault and change speed.
3. If measured winding speed is 0 and No pressure alarm is not displayed,
the equipment automatically closes turbine by-pass to reach the programmed speed.
If the problem persists for more than eleven minutes the machine alarm trips and machine sets to Stop.
Check the causes, that might be:
1.
Turbine jammed
2.
Trolley jammed
3.
Insufficient pressure
4.
Sensor faulty
5.
Sensor cable torn off
6.
Battery flat
Fix the problem, press - key to delete alarm from LCD and press Start to restart the machine.
