Monitoring Features
- If standstill is not detected, the braking cycle is interrupted after 20 s.
- The brake current switches off after 0.5 sec standstill detection.
- After activation of the start input mains frequency, phase sequence and
presence of all 3 phases is checked.
- Internal temperature monitoring protects the thyristors. By switching on
or off of the power supply this fault can be reset after the temperature
has dropped.
- To protect the power circuit the current is monitored in L1-T1. If the fixed
settings are exceeded, the device switches off and a failure indication is
displayed by a red LED.
- Monitoring of phases and phase shift protects the motor or the
system. After removing the fault this error can be reset by switching
the power supply on and off.
- External bimetallic switches or PTC-thermo sensors are used to
monitor motors on thermal overload. (variant /_1_). Overload results in
disconnection of the motor and failure indication via the red error LED.
After a cooling down period for the motor, the failure can be reset reset
switching the power supply OFF and ON again.
Notes
Variation of speed is not possible with this device. Without load a softstart
cannot be achieved. It is recommended that the softstart is protected by
superfast semiconductor fuses rated as per the current rating of the softstart
or motor. However, standard line and motor protection is acceptable, but
for high starting frequencies motor winding temperature monitoring is
recommended. The softstarter must not be operated with capacitive load
e.g. power factor compensation on the output.
In respect to safety of persons and plant only qualified staff is allowed to
work on this device.
