3. The earth leakage currents are higher than 3.5
mA (approx. 7 mA). This means that the FC motor
requires a fixed, permanent installation as well as
reinforced protective earthing.
Warning against unintended start
1. The motor can be brought to a stop by means
of digital commands, bus commands, or
references, while the FC motor is connected to
mains. If personal safety considerations make it
necessary to ensure that no unintended start
occurs, these stop functions are not sufficient.
2. While parameters are being changed, the motor
may start.
3. A motor that has been stopped may start if
faults occur in the electronics of the FC motor, or if
a temporary overload or a fault in the supply
mains or the motor connection ceases.
What if the motor does not start?
- Make sure no parameters have been changed from
initial delivery status (factory setting). Use the Local
Control Panel or serial port to reset to factory setting.
- Make sure no STOP command have been issued by
the optional control panel keyboard (local stop)
Control Panel STOP can only be restarted by the
Control Panel START button.
- Remove lid to check the Light Emitting Diodes visible
through a hole in the inside isolation cover (See the
drawing), follow table below.
Warning:
Extreme care must be taken when
operating the unit with open lid.
