0xD506 Pump cleaning not
possible
Pump cleaning cannot be
started. The drive needs to be
in remote control and start
signal is activated.
Change control location to Auto.
0xD507 Pump cleaning
needed
Dirt detection indicates that the
pump needs cleaning but
automatic pump cleaning is not
allowed.
Perform pump cleaning manually.
Start pump cleaning by changing
parameter 83.12 Manually force
cleaning to Start cleaning now.
0xD508 High level
Programmable warning:
76.93 LC high level action
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.
Check analog level sensor.
Check that all the pumps are operating
normally.
Check parameters 76.91 LC high level
switch and 76.93 LC high level action.
0xD509 Low level
Programmable warning:
76.92 LC low level action
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.
Check analog level sensor.
Check that all the pumps are operating
normally.
Check parameters 76.90 LC low level
switch and 76.92 LC low level action.
0xD50A Running dry
Programmable warning:
82.20 Dry run protection
Dry run protection is activated. Check the pump inlet for sufficient
water level.
Check dry run protection settings in
parameters 82.20 Dry run protection
and 82.21 Dry run source.
D50C Maximum flow
protection
Programmable warning:
80.17 Maximum flow
protection
Actual flow is exceeded the
defined warning level.
Check the system for leakages.
Check flow protection settings in
parameters 80.15 Maximum flow, 80.17
Maximum flow protection and 80.19
Flow check delay.
D50D Minimum flow
protection
Programmable warning:
80.18 Minimum flow
protection
Actual flow is below the
defined warning level.
Check that the inlet and outlet valves
are open.
Check flow protection settings in
parameters 80.16 Minimum flow, 80.18
Minimum flow protection and 80.19
Flow check delay.
D50E Outlet minimum
pressure
Programmable warning:
82.30 Outlet minimum
pressure protection
Measured outlet pressure is
below the defined warning
limit.
Check the pump outlet for leakages.
Check the configuration of outlet
pressure protection.
See parameters 82.30 Outlet minimum
pressure protection and 82.31 Outlet
minimum pressure warning level.
D50F Outlet maximum
pressure
Programmable warning:
82.35 Outlet maximum
pressure protection
Measured outlet pressure is
above the defined warning
limit.
Check the pump outlet for blockages or
closed valve.
Check the configuration of outlet
pressure protection.
See parameters 82.35 Outlet maximum
pressure protection and 82.37 Outlet
maximum pressure warning level.
