Active Faults - Siemens S120 Instructions Manual

11 ACTIVE FAULTS

SIEMENS inverters emit warnings FAULT type A or F.
Errors are identified by the letter of the type (A/F), followed by a 5-digit code that allows you to trace the
causes that have generated and their possible solutions.
The errors are displayed on both: on the BOP operator panel, and in a special STARTER screen, clicking the
bookmark Alarms in the lower left (see illustration)
Bookmark Alarms and messages are only available ONLINE
A description of the error, the possible causes and solutions, you can get by clicking 2 times on the alarm
code; this will automatically open the help guide (where available)
The list of all possible errors and their solutions can be found in the standard manual SIEMENS S120, "LH1
List Manual", which we refer.
To reset an error, select the error and press the Confirm button, or act through the BOP (see).
Some type of errors could be reset automatically by the main control board, by using the input port X131.2
(see the application diagram to the paragraph 7.4 SIEMENS S120 ELECTRICAL WIRING).

In general, facing to a non-compliance detected, the inverter behaves as follows:

errors Type A (Alarm) are minor errors that, in principle, have no influence on the behavior of
the inverter / LIFT.
The error in the cause still remains active until it has determined, then is reset.

Errors TYPE F (Fault) are serious flaws that lead to the immediate arrest of the inverter and the
lift that is placed safely via simultaneous closing of the solenoid downward (EVD).
The error F remains active even after the disappearance of the cause that determines it and has to be
reset manually (via PC or PO) or via the microphone input from the framework (X131.2).
