Range Description
RATED LINE VOLT.
6600 VOLT
2300-15000 Sets HRVS-DN’s rated voltage.
HRVS-DN’s rate voltage should be as shown on its label. Refer
to section
13.2 on page 112.
Note
:
Setting RATED LINE VOLTAGE to other than the value on the
label will cause a wrong operation and wrong readings of the
soft starter.
STARTER FLC
150 AMP.
20 – 1800A
Sets HRVS-DN’s FLC (Full Load Current)
HRVS-DN’s FLC should be as shown on its label. Refer to
section
13.2 on page 112.
Note
:
Setting FLC to other than the value on the label will cause a
wrong operation and wrong readings of the soft starter.
MOTOR FLA
150 AMP.
30-100% of
STARTER
FLC
Sets motor’s FLA (Full load Ampere)
Should be programmed as shown on the motor’s name plate.
RATED MOTOR PWR
1000 KW
50-40000KW Sets motor rated power as indicated on its name plate.
SERVICE FACTOR
100%
100-130% Sets motor rated service factor as indicated on its name plate.
UNDERCURR. TRIP
0% OF FLA
0%(=OFF)/
20-90% of FLA
Sets UNDER CURRENT TRIP protection.
Sets the time delay for UNDER CURRENT TRIP protection.
Trips the HRVS-DN when the motor current drops below the
level that was set for a time period longer than UNDER
CURRENT DELAY.
Note
:
Operational when the motor is running (the RUN LED is lit).
Can be set to AUTO RESET. Refer to section
7.8.6 page
71.
UNDERCURR. DELAY
10 SEC.
1-40SEC.
O/C – SHEAR PIN
850% OF FLA
100-850% of
motor’s FLA
setting
Sets OVER CURRENT SHEAR PIN protection.
Sets O/C – SHEAR PIN DELAY time.
Operational when HRVS-DN is energized and has three trip
functions:
At all time
- If I > 850% of FLC it trips the HRVS-DN within 1
cycle (overrides the value of the O/C – SHEAR PIN setting).
At starting process
- If I > 850% of FLA it trips the HRVS-DN
after O/C DELAY (see here after)
At run time
- If I > O/C – SHEAR PIN setting of FLA it trips the
HRVS-DN after O/C DELAY.
Note:
The OVER CURRENT SHEAR PIN protection is not intended
to replace fast acting fuses to protect from short current!
O/C DELAY
0.5 SEC.
0.0 – 5sec.
Note:
When set to
0.0 it is
practically up
to 200msec.
