9.2.2 - Drive alarms
Drive alarms or alerts for VLT drive failure are displayed
based on the following formula: 16000+X*1000+YYY for
alarms and 34000+X*1000+YYY for alerts. X stands for
the number of the circuit and YYY is the alarm/alert code.
For example, alarm codes for “VLT Fan Drive Failure” are
as follows: 17YYY (circuit A) and 18YYY (circuit B).
Drive alarms for pump drive failure are displayed based on
the following formula: 19000+YYY. YYY is the alarm
code.
The tables below present the most common alarms
associated with the variator malfunction. Please refer to
the applicable Schneider documentation for more
information on other alarms.
