Controller Specific Instructions & Troubleshooting
Alarms: Steadypres
OVER
CURRENT %
The current
exceeded the allowable tolerance on
the current set. The inverter
stops the pump, the rearm is only manual.
CURRENT
LIMIT
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 inventer does not stop the pump.
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 inventer does not stop the pump.
DRY
RUNNING
(applications WITH
flow Sensor)
Occurs if, in the absence of flow,
the pump falls to reach the pressure of the set but
does not even reach a predeterminded 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 inventer re-starts in automatic mode.
DRY
RUNNING PF
(only T/T models)
Occurs if the electrical parameter COSFI (power factor) falls to value indicating the
unload operation of engine. the inverter stops the pump. the error is reset after the
time TP.
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.
VOLTLAGE
ERROR L
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 TEMP.
BOX
(Only T/T models)
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 models)
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 TEMP.
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 in-
verter 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 cause could be integrity of the cable and the connection ports or an
electronic board fault.
PHASE
ERROR
(Only for models with three-phase output)
lack of phase towards the motor
during
operation. The inverter stops the pump; reset is manual only.
LOW LEVEL
This occurs when the digital input EL is
configured as “WATER LEVEL” (level signal)
and there is no signal
. When the signal returns, the message disappereas and the
inverter operates normally again.
EXT OFF
This occurs when the digital input EL
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.
