Code Warning Cause Remedy
551 Undervoltage Power supply is too low. Check power supply.
Additional information about causes and remedy:
• The pump is running. Undervoltage reduces the performance of the pump. If the voltage falls be-
low 324 V, the reduced operation cannot be maintained.
552 There is externally generated
flow through the pump in the
direction of flow. External influences cause flow in
the pump’s direction of flow. Check power control of the
other pumps.
Additional information about causes and remedy:
Operation cannot be continued. Possible causes:
• The pump can still start.
553 Electronic module is defective. Electronic module is defective. Replace electronic module.
Additional information about causes and remedy:
• The pump is running, but cannot provide full power under the circumstances.
Contact service.
555 No plausible sensor value at
analogue input AI 1. No plausible sensor value at
analogue input AI 1. Check configuration of the input
and connected sensor.
Additional information about causes and remedy:
• Wrong sensor values may lead to substitute operation modes that ensure functioning of the pump
without the required sensor value.
556 Cable break at analogue input
AI1. The configuration and the
present signal help identify the
cable break. Check configuration of the input
and connected sens.
Additional information about causes and remedy:
• Cable break detection may lead to substitute operation modes, which ensure functioning of the
pump without the required external value.
557 No plausible sensor value at
analogue input AI2. The configuration and the
present signal lead to an unus-
able sensor value. Check configuration of the input
and connected sensor.
Additional information about causes and remedy:
• Wrong sensor values may lead to substitute operation modes that ensure functioning of the pump
without the required sensor value.
558 Cable break at analogue input
AI2. The configuration and the
present signal help identify the
cable break. Check configuration of the input
and connected sensor.
Additional information about causes and remedy:
• Cable break detection may lead to substitute operation modes, which ensure functioning of the
pump without the required external value.
560 Incomplete software update. The software update was not
completed. Software update with a new
software bundle is recommen-
ded.
Additional information about causes and remedy:
• Software update was not carried out; pump continues to operate with previous software version.
561 Voltage analogue input over-
loaded (binary). Voltage analogue input short-
circuited or too heavily loaded. Check line and consumers con-
nected to power supply of ana-
logue digital input for short-cir-
cuit.
Additional information about causes and remedy:
• Binary inputs are impaired. Functions of binary inputs are not available.
562 Voltage analogue input over-
loaded (analogue). Voltage analogue input short-
circuited or too heavily loaded. Check line and consumers con-
nected to power supply of ana-
logue input for short-circuit.
Additional information about causes and remedy:
• Functions of the analogue inputs are impaired.
