6.6.16 Setup of outputs OUT1, OUT2
This section illustrates the functions and possible configurations of the outputs OUT1 and OUT2 via parameters O1
and O2.
For electrical connections, see par. 2.3.4.
The default settings are those in Table 28.
6.6.16.1 O1: Output 1 function setting
Output 1 notifies of an active alarm (i.e. that there is a system block). The output enables use of a normally closed or
normally open voltage-free contact.
Parameter O1 is associated with the values and functions specified in Table 29.
6.6.16.2 O2: Output 2 function setting
Output 2 notifies of electric pump running status (pump on/off). The output enables use of a normally closed or
normally open voltage-free contact.
Parameter O2 is associated with the values and functions specified in Table 29.

6.6.17 SF: Starting frequency
Available only for type M/M inverters.
SF is the frequency set for the pump's turn on, in a set time ST (see section 6.6.18. The default value corresponds to
the pump's rated frequency, but it can be changed pressing "+" and "-"; it can be changed in a range between FN and
FN-50%. When FL value is higher than FN-50%, SF will be limited to the FL minimum frequency. For example when
FN = 50Hz, SF can be set between 50 and 25Hz. When FN = 50Hz and FL = 30 Hz, SF can be set between 50 and
30Hz.
6.6.18 ST: Starting time
Available only for type M/M inverters.
ST is the period of time in which SF frequency is supplied (see section 6.6.17), before the frequency is automatically
managed by PI parameter. The ST default value is 1 sec. and it its normally the best for most of the pumps. In any
case, ST can be changed between 0 and 3 secs. When Ft = 0 secs, frequency will be immediately managed by PI and
the pump will turn on at the rated frequency.
6.6.19 RF: Fault and warning log reset
To clear the fault and warning log, press and hold the buttons + and – simultaneously for at least 2 seconds. The
number of faults present in the log (max. 64) are summarised below the RF symbol.
The log can be viewed from the MONITOR menu on the FF page.
