68 Fault tracing
The four-digit code number in parenthesis after the fault is for the fieldbus communication.
See chapters
Fieldbus control with embedded fieldbus
and
Fieldbus control with fieldbus
adapter
in
ACS355 User’s manual (3AUA0000066143[English])
.
How to reset
During a fault condition, you can reset the inverter by pressing the keypad key
(basic
control panel) or
(assistant control panel) through digital input or fieldbus or by
switching off the supply voltage for a while. The source for the fault reset signal is selected
by parameter 1604 FAULT RESET SEL. You can restart the motor after the fault is
removed.
Fault history
The fault history stores all the detected faults. The latest faults are stored together with the
time stamp.
Parameters 0401 LAST FAULT, 0412 PREVIOUS FAULT 1 and 0413 PREVIOUS
FAULT 2 store the most recent faults. Parameters 0401...0409 show the inverter operation
data at the time the latest fault occurred. The assistant control panel provides additional
information about the fault history.

Fault messages
The following faults messages are generated by the solar pump inverter.

What to do
210
DRY RUN
The inverter consumes less
current than the current set in
.
This condition occurs when
there is no water flowing in the
pump.
• Check the availability of water
at the pump inlet.
• Check for any blockage in the
pump.
216
PV MAX VOLT
The DC bus voltage in the
inverter is above the voltage set
in
• Check the number of PV cells
connected in series.
• Ensure that voltage is less
than the voltage set in
Maximum allowed voltage:
• 400 V unit: 800 V
• 200 V unit: 400 V
