Warnings/alarm messages
A warning or an alarm will appear in the LEDs on
the LCP2. A warning will be shown until the fault
has been corrected, while an alarm will continue to
flash until the [STOP/RESET] key is activated.
The table shows the various warnings and alarms
shown in the LCP2, and whether the fault locks the
frequency converter. After a
Trip locked
(alarm and
warning LEDs flash at the same time), the mains
supply is cut off and the fault is corrected. The
mains supply is reconnected and the frequency con-
verter is reset. The frequency converter is now
ready. A
Trip
can be reset manually in three ways:
1. Via the operating key [STOP/RESET].
2. Via a digital input.
3. Via serial communication.
It is also possible to choose an automatic reset in
parameter 405
Reset function
. When a cross ap-
pears in both warning and alarm, this can mean that
a warning comes before an alarm. It can also mean
that it is possible for the user to programme whether
a warning or an alarm will appear for a given fault.
For example, this is possible in parameter 128
Motor
thermal protection
. After a trip the motor will coast,
and alarm and warning will blink on the frequency
converter, but if the fault disappears only the alarm
will blink. After a reset the frequency converter will
be ready to start operation again.
No.
