NOTE!
This parameter is used only if P3.21.2.1 = 2 PID sleep (level).
10.22.3 PRIMING PUMP
A priming pump is a smaller pump that primes the inlet of the main pump to prevent suction
of air.
The priming pump function controls a priming pump with a digital output signal. You can set
a delay to start the priming pump before the main pump starts. The priming pump operates
continuously while the main pump operates. If the main pump goes into sleep mode, the
priming pump also stop for that time. When waking up from sleep mode, the main pump and
the priming pump start simultaneously.

P3.21.3.1 PRIMING FUNCTION (ID 1677)
Use this parameter to enable the Priming pump function.
A priming pump is a smaller pump that primes the inlet of the main pump to prevent the
suction of air. The priming pump function controls a priming pump with a relay output signal.
P3.21.3.2 PRIMING TIME (ID 1678)
Use this parameter to set the time that the priming pump operates before the main pump
starts.

ADVANCED HARMONIC FILTER
P3.22.1 CAPACITOR DISCONNECTION LIMIT (ID 15510)
Use this parameter to set the disconnection limit for the advanced harmonic filter. The value
is in percentage of the drive nominal power.
