ALARMS
OVER
CURRENT %
The current
exceeded the allowable tolerance
on the current set.
The inverter stops the pump, the rearm is only manual.
CURRENT
LIMIT
The current
exceeded the module current capacity.
The inverter stops the pump, the rearm is only manual.
i DRY
Occurs if, in the absence of flow,
the pump cannot reach the SET pressure
, but
can
reach at least a pre-determined percentage
of the SET pressure, defined through
the parameter Pd. The inverter does not stop the pump, which continues to work with
the message “i-DRY” on the display.
DRY RUNNING
Occurs if, in the absence of flow,
the pump fails to reach the pressure
of the set but
does not even reach a predetermined percentage of the SET pressure
, expressed
by the parameter Pd; the inverter stops the pump.
The error is reset after the time TP and the inverter re-starts in automatic mode.
LOW PRESS
Occurs if the pump is running at maximum frequency (50/60 Hz), in the presence of
flow, and
the pressure doesn’t reach 0.3 bar
; the inverter stops the pump.
The error is reset after the time TP and the inverter re-starts in automatic mode.
LOW VOLTAGE
a
voltage drop
has occurred beyond minimum operating threshold. The inverter stops
the pump. The error is reset after one minute, and the inverter re-starts in automatic
mode.
HIGH VOLTAGE
a
voltage peak
has occurred beyond maximum operating threshold. The inverter stops
the pump. The error is reset after one minute, and the inverter re-starts in automatic
mode.
HIGH TEMP.
BOX
(only T/T mod.)
The
temperature inside the inverter
has reached 65 ° C; is automatically
limited the
maximum
frequency of 5 Hz but
the drive continues to run
, the error is reset below
60 ° C
OVER TEMP.
BOX
(only T/T mod.)
The
temperature inside the inverter
has reached 80 ° C,
the inverter stops the
pump,
the error is reset below 60 ° C and the drive will restart automatically
HIGH
TEMPERATURE
MOD
The
module temperature
has reached the first alarm threshold;
the maximum
working frequency
is automatically limited, but
the drive continues to run
, the error
is reset when the module temperature returns below 70 °C
OVER TEMP
MOD
The
module
temperature
has reached
the second alarm threshold
,
the inverter stops
the pump,
the error is reset
when the module temperature returns below 70 °C
and the
drive will restart automatically
INPUT ERROR
There has been a
reversal of the power connections
/ output to the motor. the
inverter is locked, the error is reset by connecting the cables correctly in the terminal
COM ERROR
communication has been interrupted
between the control board and the power
board; the causes could be the integrity of the cable and of the connection ports or an
electronic board fault.
PHASE ERROR
(only for models with three-phase output)
lack of a phase towards the motor
during
operation. The inverter stops the pump ; reset is manual only.
LOW LEVEL
this occurs when the digital input EI is
configured as “WATER LEVEL” (level signal)
and there is no signal.
When the signal returns, the message disappears and the
inverter operates normally again.
EXT OFF
this occurs when the digital input EI is
configured as “EXT ENABLE” (control
enabled from outside) and there is no signal
. When the signal returns (external
enabling) the message disappears and the inverter operates normally again.
OFF
It occurs when the supply voltage is disconnected; the capacitors are discharged, for
security reasons, from the discharge resistors. The process takes about 10 sec
