Display and Default
Values
Range Description
SET CURVE 0 FLT
ENABLE
ENABLE/
DISABLE
SET CURVE TO 0 message may occur seldom during starting with
special conditions of mains and load. Change start (and stop, if
used) curve to SOFT START CURVE 0 and SOFT STOP CURVE
0.
Set SET CURVE 0 FLT to DISABLE, only if SET CURVE TO 0 FLT
fault occurs during starting and if SOFT START CURVE 0 is not
good enough for the application.
When set to DISABLE verify that motor starts normally in the
selected curve.
PWR ON & NO STRT
ENABLE
ENABLE/
DISABLE
Sets POWER ON & NO STRT trip
POWER ON & NO START is operational upon mains voltage
connection. It trips the HRVS-DN when mains voltage is connected
to the HRVS-DN for more than 30 seconds without a start signal.
Set to DISABLE only in special occurrences. (Consult factory!)
INSULATION ALARM
OFF
OFF/ 0.2–
20Mohm
Sets INSULATION ALARM level.
Activates INSULATION ALARM trip.
Applicable only if optional insulation PCB and resistor unit are
installed and connected.
Insulation testing is enabled only when motor is not running and
after 60 seconds in the
Stop
state.
While motor is running the value of the insulation resistance shown
in the display is the last measured value prior to starting of the
motor. While testing, if the insulation level drops below Alarm level -
a message: MOTOR INSULATION ALARM will display and the
insulation alarm relay will be energized. The
Fault
LED on the
control keypad of the HRVS-DN will blink.
If insulation level will return to normal for more than 60 seconds the
alarm will automatically reset.
While testing, if the insulation level drops below Fault level - a
message: INSULATION TRIP will display and the fault relay of the
HRVS-DN will go to the fault position (as programmed in the I/O
PROGRAMMING PARAMETERS).
The
Fault
LED on the front of the HRVS-DN will light. In this status
motor can not be started.
If insulation level will return to normal the HRVS-DN will not
automatically reset.
INSULATION TRIP
OFF
OFF/ 0.2–
20Mohm
PHASE SEQUENCE
POSITIVE
POSITIVE/
NEGATIVE/
IGNORE
Sets PHASE SEQUENCE protection of the soft starter.
Allows to start the motor in POSITIVE sequence of the mains OR in
the NEGATIVE sequence of the mains or, when set to IGNORE, in
both sequences.
