ADDITIONAL FEATURES - TROUBLESHOOTING

A. 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.

B. 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).

C. 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.

D. 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. A)

E. The machine ends working cycle but the LCD displays alarm 4, i.e. Speed

fault:

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, 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.
