In all other cases the operation will be according to standard parameter value.
The pressure threshold is adjustable by acting directly on the pressure switch regulation)
Don’t set the reduced high speed value, too low: always respect P1007 >30Hz

stalled valve.
11 ACTIVE FAULTS & ALERT
SIEMENS inverters emit warnings type A (ALERT) or F (FAULT).
Errors are identified by the letter of the type (A/F), followed by a digit code that allows you to trace the
causes that have generated and their possible solutions.
The errors are displayed: on the BOP operator panel.
A description of the error, the possible causes and solutions, is available in the following chapter.
The list of all possible errors and their solutions can be found in the standard manual SIEMENS V20, to
which you could refer.
To
reset an error
, select the error and follow the following procedure through the BOP (see below).
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 A, 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 valve.
The error F remains active even after the disappearance of the cause that determines it and has to be
reset manually.
Note:
If there are multiple active faults and alarms, the BOP first displays all faults one after another. Once
all faults are displayed, it displays all alarms in succession.
Immediately when a fault occurs the fault icon
shows and the display transitions to the faults screen. The
faults screen displays the fault number proceeded by "F" (FAULT).
Acknowledging / clearing faults
To navigate through the current list of faults, press
▲ or ▼.
To clear / acknowledge the fault, press OK.
To ignore the fault, press M.
After you acknowledge or ignore the fault, the screen returns to the previous display. The fault icon remains
active until the fault is cleared / acknowledged.
Note:
Under the following circumstances, the faults screen displays again:
