7.17.15 User defined protection
You can use a Programmable digital input in combination
with an external device/sensor to use your own specified
protection. An example is the CEM11-FBP ground fault
sensor.
User defined protection has these parameters:
Parameter Description Setting range Default value
18.01 User defined DI status Sets if the signal is active high or
active low.
0 ... 1 1
18.02 User defined trip time Sets the time to trip. 0.0 ... 60.0 s 1.0 s
18.03 User defined out Identifies the Event groups this
protection is part of.
Eventgroup 0 ... 6 0000010
18.04 User defined op Sets the operation of this
protection.
Off, Stop manual,
Stop auto, Indication.
Off
7.17.16 Ground fault protection
This protection senses if the absolute value of the sum of
the 3 line currents is too high, which indicates that there
is a ground fault.
Note that the currents measurement in the Softstarter is
not accurate or fast enough to protect people. The only
purpose of this function is to protect equipment.
Ground fault protection has these parameters:
Parameter Description Setting range Default value
18.05 Ground fault trip time Sets the trip time for the ground
fault protection.
0.1 ... 10.0 s 0.5 s
18.06 Ground fault out Identifies the Event groups this
protection is part of.
Eventgroup 0 ... 6 0000010
18.07 Ground fault op Sets the operation of this
protection.
Off, Stop manual,
Stop auto, Indication.
Off
7.17.17 Too long current limit protection
This protection sense if the current limit is longer in
operation than the set trip time. The starting condition is
too heavy for the set current limit.
Too long current limit protection has these
parameters:
Parameter Description Setting range Default value
18.08 Too long curr lim trip time Sets the trip time for the too long
time at current limit protection.
1 ... 600 s 10 s
18.09 Too long curr lim out Identifies the Event groups this
protection is part of.
Eventgroup 0 ... 6 0000010
18.10 Too long curr lim op Sets the operation of this
protection.
Off, Stop manual,
Stop auto, Indication.
Off
