7.15.16 Earth fault protection
Programmable digital input can be used in combination
with external device/sensor to provide the possibility of
handling their own defined protection.
This protection detects if the absolute value of the sum
of the three line currents is too high, which indicates that
there is an earth fault.
Note that the currents measurements in the softstarter is
not accurate or fast enough to protect people. The only
purpose of this function is to protected equipment.
Earth fault protection is configured with the following
parameters:
Parameter
18.05 Earth fault trip time
18.06 Earth fault out
18.07 Earth fault op
7.15.17 Too long current limit protection
This protection detacts if the current limit has exceeded
the set value. The starting condition is too heavy for
the set current limit. Check starting conditions and
parameters.
Too long current limit protection is configured with the
following parameters:
Parameter
18.08 Too long curr lim trip time
18.09 Too long curr lim out
18.10 Too long curr lim op
7.15.18 HMI failure protection
This protection detacts if there is communication
disturbance between the softstarter and the HMI.
If the communication with the HMI is lost for more than
approximatlely 600 ms this protection is activated.
This protection has a special action in addition to the
common types of operation:
Switch to I/O-control.
HMI failure protection is configured with the following
parameters:
Parameter
19.01 HMI failure out
19.02 HMI failure op
