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
(only with flow
sensor)
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.
DRY RUNNING
(
WITH
flow sensor)
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
DRY RUNNING
(
WITHOUT
flow
sensor)
Occurs if the pump
fails to reach the predetermined percentage of the SET pressure,
expressed by the parameter Pd; the inverter stops the pump. the error is reset after the time TP
DRY RUNNING PF
Occurs if the electrical parameter
COSFI (power factor) falls to a value indicating the
unload operation of the engine.
the inverter stops the pump. the error is reset after the time
TP
P NC
No pressure sensor signal or signal is outside the sensor range; DGBOX stops the system and
indicates the P SENS ERR message.
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
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
The inverter internal temperature has reached the
attention
threshold.
It is automatically
limited the maximum
frequency but
the drive continues to run
, the error
is reset below 60 ° C
OVER TEMP. BOX
The inverter internal temperature has reached the
critical
threshold.
The inverter
stops the pump.
the error is reset below 60 ° C and the drive will restart automatically
HIGH TEMP. CAP
The capacitor temperature has reached the
attention
threshold.
It is automatically
limited the maximum
frequency but
the drive continues to run
, the error
is reset below 60 ° C
OVER TEMP. CAP
The capacitor temperature has reached the
critical
threshold; the inverter
stops the pump.
The error is reset below 60 ° C and the drive will restart automatically
HIGH TEMP. MOD
The
module temperature
has reached the
attention
threshold.; it is automatically
limited the
maximum
frequency but
the drive continues to run
, the error is reset below 70 ° C
OVER TEMP. MOD
The
module
temperature
has reached the
critical threshold;
the inverter stops the pump,
the error is reset 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.
