Values
Range Description Remarks
STARTER FLC
58 AMP.
8 – 3000A Sets RVS-
DN’s FLC
(Full Load
Current)
RVS-DN’s FLC should be as shown on its name
plate. Refer to section
6.1 on page 54.
MOTOR FLA
58 AMP.
50-100% of
STARTER
FLC
Sets motor’s
FLA (Full load
Ampere)
Should be programmed as shown on the motor’s
name plate.
Note
:
When the RVS-DN is installed Inside Delta set
MOTOR FLA = <rated motor current>/1.73.
CONNECTION TYPE
LINE
LINE,
INSIDE
DELTA
Sets RVS-
DN’s
connection
type.
Factory preset - features and functions not
active when Inside Delta mode is configured:
• Pulse Start.
• Curve selection (CURVE 0!! only)
• Slow speed
• PHASE SEQUENCE “Off” mode
Refer to section
4.22 on page 30 for further
information.
Note
:
When the RVS-DN is installed INSIDE DELTA
set MOTOR FLA = <rated motor current>/1.73.
UNDERCURR. TRIP
0% OF FLA
0%=off;
20-90% of
FLA
Sets UNDER
CURRENT
TRIP
protection.
Trips the RVS-DN when the motor current drops
below the level that was set for a time period
longer than UNDER CURRENT DELAY.
UNDERCURR. DELAY
10 SEC.
1-40sec. Sets the time
delay for
UNDER
CURRENT
TRIP
protection.
Note
:
Operational when the motor is running (the RUN
LED is lit).
O/C – SHEAR PIN
850% OF FLA
100-850% of
motor’s FLA
setting
Sets OVER
CURRENT
SHEAR PIN
protection.
Operational when RVS-DN is energized and has
three trip functions:
At all time
- If I > 850% of FLC it trips the RVS-
DN within 1 cycle (overrides the value of the
O/C – SHEAR PIN setting).
O/C DELAY
0.5 SEC.
0.0 – 5sec. Sets O/C –
SHEAR PIN
delay time.
At starting process
- If I > 850% of FLA it trips
the RVS-DN after O/C DELAY (see here after)
At run time
- If I > O/C – SHEAR PIN setting of
FLA it trips the RVS-DN after O/C DELAY
Important Note
:
The O/C SHEAR PIN is not intended to replace
the fast acting fuses, required to protect the
thyristors. Refer to section
4.18 on page 29.
