Cause
Pump cleaning cannot be
started. The drive needs to be
in remote control and start
signal is activated.
Dirt detection indicates that the
pump needs cleaning but
automatic pump cleaning is not
allowed.
Water level is reached the high
level limit. Level control is
unable to control the level for
the following reasons:
• running out of pumping
capacity.
• analog feedback sensor
failure.
Water level is reached the low
level limit. Level control is
unable to control the level for
the following reasons:
• running out of pumping
capacity.
• analog feedback sensor
failure.
Dry run protection is activated.
Actual flow is exceeded the
defined warning level.
Actual flow is below the
defined warning level.
Measured outlet pressure is
below the defined warning
limit.
Measured outlet pressure is
above the defined warning
limit.
