2.3 PROTECTION FEATURES
- Battery polarity inversion:
It is necessary to fit a MAIN CONTACTOR to protect the inverter against reverse
battery polarity and for safety reasons.
- Connection Errors:
All inputs are protected against connection errors.
- Thermal protection
If the chopper temperature exceeds 75°C, the maximum current is reduced in
proportion to the thermal increase. The temperature can never exceeds 100°C.
- External agents:
The inverter is protected against dust and the spray of liquid to a degree of
protection meeting IP54.
- Protection against uncontrolled movements:
The main contactor will not close if:
- The Power unit is not functioning.
- The Logic is not functioning perfectly.
- the output voltage of the accelerator does not fall below the minimum voltage value
stored, with 1V added.
- Running microswitch in closed position.
- Low battery charge:
when the battery charge is low, the maximum current is reduced to the half of the
maximum current programmed.
- Protection against accidental Start up
A precise sequence of operations are necessary before the machine will start.
Operation cannot begin if these operations are not carried out correctly.
Requests for drive, must be made after closing the key switch
