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
variable frequency drive. After a Trip locked (alarm and
warning LEDs flash at the same time), the electrical
supply is cut off and the fault is corrected. The electrical
supply is reconnected and the variable frequency drive
is reset. The variable frequency drive 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 appears
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 program 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 variable
frequency drive, but if the fault disappears only the
alarm will blink. After a reset the variable frequency
drive will be ready to start operation again.
