Set-up Procedure
Soft start:
1. Press start button. Turn potentiometer "M
to turn without excessive humming.
2. Adjust potentiometer "t
" to give desired ramp time.
on
3. On correct setting the motor should accelerate up to nominal speed.
If the start takes too long fuses may blow, especially on motors with
high inertia.
Attention:
If the ramp-up time is adjusted to short, the internal
bridging contact closes before the motor is on full speed.
This may damage the bridging contactor or bridging
relay.

Set-up Procedure
Braking:
Press stop button and adjust with potentiometer "I
the desired value. Please adjust the braking current high enough so that
the brake time is shorter than 10 sec. The brake current should be limited to
1.8 ... 2 x I
of the motor. If the brake function at 1.8 ... 2 times of rated
N
current has not finshed within 10 sec the load is too high. The next larger
motor shoud be used. To avoid an overload of the device and the motor,
the brake current should be measured with a moving coil instrument in the
motor connecting line T1.
Temperature monitoring:
BI 9028 features overtemperature monitoring of its internal power
semiconductors. The unit is therefore protected against overheating during
the set up procedure. BI 9028 can be reset after the semiconductors have
cooled down by momentarily removing the auxiliary supply voltage.
Safety Notes
-
Never clear a fault when the device is switched on.
-
The user must ensure that the device and the necessary
components are mounted and connected according to the locally
applicable regulations and technical standards.
-
Adjustments may only be carried out by qualified specialist staff and
the applicable safety rules must be observed.
