Safety
Excessive "slow down" limit
In the engine's acceleration phase, the red led flashing;
the motor slows down in an excessive way and stops after
80s at fault (led red fixed).
Current protection of the Thyristor
The FANSTART will display a fault (red LED) if the current
exceeds the thyristor current limits:
125A during 0.4s
87.4A during 2s
75A during 6s.
62.5A during 20s.
Start up sequence too long
If at the end of 80s the fanstart did not commutate the
motor on the electrical network, the motor stops: fixed red
led.
Nota :
In the case of a resistant air sock, one can reduce
the phase of pre-inflation to 5 seconds (thanks to the
switch, fig. 16)
