period.
SOFT START: input signal to activate the soft start function. This
function must be activated (pin-7 shorted with pin-9) if the pump
remains unused for 1 month or more, and deactivated for the next
run-up. The soft Start phase is around 45 minutes long. The soft start
function is factory enabled for the first system start-up. After the first
pump start-up until the normal status, the soft start is automatically
disabled.
ANALOG OUTPUT: s output signal is a voltage (from 0 to 10 Vdc)
proportional to a reference quantity (frequency or power) set by the
user through serial line (window 111). The default setting is the
frequency (see the following example diagram).
The voltage is provided between pins 14 and 15. An high impedance
input should be connected to this output (> 100 kΩ).
