loss
Safe torque off function
is active, ie. STO circuit 2
is broken.
D401 Max cleaning fault
Programmable fault:
83.35 Cleaning count
fault
The maximum number of
cleanings are reached in
the defined time. The
pump cleaning is unable
to clean the pump and
hence, manual cleaning is
required.
Check the pump for blockages.
Clean the pump manually if
needed.
Check parameters

83.37 Maximum
cleaning count

D406 Maximum flow
protection
Programmable fault:
80.17 Maximum flow
protection
Actual flow is exceeded
the defined fault 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
.
D407 Minimum flow
protection
Programmable fault:
80.18 Minimum flow
protection
Actual flow is below the
defined fault level. Check that the inlet and outlet
valves are open.
Check flow protection settings in
parameters
80.16 Maximum flow
,
80.18 Minimum flow protection
, and
80.19 Flow check delay
.
D408 Outlet minimum
pressure
Programmable fault:
82.30 Outlet minimum
pressure protection
The measured outlet
pressure is below the
defined fault limit. Check the pump outlet for
leakages. Check the
configuration of outlet pressure
protection.
See parameters
82.30 Outlet
minimum pressure protection
and
82.32 Outlet minimum pressure
fault level
.
D409 Outlet maximum
pressure
Programmable fault:
82.35 Outlet maximum
pressure protection
The measured outlet
pressure is above the
defined fault limit.
Check the pump outlet for
blockages or closed valve.
Check the configuration of outlet
pressure protection.
