18
Selector Guide – How to Select?
• Motor current and connection
– Starter current ≥ motor FLA
!!!
19
Selector Guide – How to Select?
• Motor current and connection
– In line/Inside delta
• When soft starter is connected “inside delta” lower
current is running through the soft starter.
20
Selector Guide – How to Select?
• Motor current and connection
– In line/Inside delta
• Advantages:
– Smaller dimensions
– Less expensive Soft Starter
• Disadvantages:
–
–
–
–
–
–
–
Six wire to the motor – more complicated wiring.
No pulse start
No curve selection (Curve 0! Only)
No energy save
No slow speed
No phase sequence “off” mode.
Although current inside delta is reduced by 1.73 (√3), Soft starter
current is reduced by 1.5.
For example: for a 870A motor, you can choose a 580A soft starter
when connected “inside delta”

Bypass Contactor
• Models 8-820A can operate continuously
without a bypass contactor
• All models from RVS-DN 950A and up and
RVS-DN 1000V must be implemented with
a bypass contactor
• Bypass preparation is standard in models
RVS-DN 85-170A.

of the O/C – SHEAR PIN setting).
• 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

2 !!SOFT START CURVE
3 !!SOFT START CURVE
4 (TORQUE)
• START CURVE 0 – Standard curve (Default). This curve is the most
suitable curve for preventing prolonged starting and motor overheating.
Note:
When RVS-DN is connected Inside Delta, the RVS-DN will always use
CURVE 0 regardless of the curve defined.
• START CURVES 1-3 - Pump Control - Induction motors produce peak
torque of up to 3 times the rated torque towards the end of starting
process. In some pump applications, this peak may cause pressure surge
in the pipes.
• Start Curves 1, 2, 3 – During acceleration, before reaching peak torque,
the Pump Control Program automatically controls the voltage ramp-up,
thus, reducing peak torque.
75
Start Parameters
When starting with a standard soft starter Starting Torque is reduced drastically,
however Peak Torque still remains high,
causing high Acceleration Torque towards the
end of the starting process.
Peak & Acceleration Torque must be reduced
to extend the Acceleration time.

Start Parameters
PULSE TIME
0 sec.
PULSE TIME - Intended to start high friction loads that
require high starting torque for a short time.
• A pulse of 80% Un without CURRENT LIMIT is
initiated to break the load free.
• Pulse duration is adjustable, 0.1–1sec. After this
pulse the voltage is ramped down to INITIAL
VOLTAGE setting before ramping up again to full Un
voltage according to the START PARAMETERS
settings.
Note:There is no PULSE START function when RVSDN is connected Inside Delta.

•
STOP CURVE 0 – Standard Curve (Default) – voltage is linearly reduced from nominal to zero.
The most stable and suitable curve for preventing prolonged stopping and motor overheating.
• STOP CURVES 1, 2, 3 Pump Control – In some pump applications, when pumping to higher
elevation a considerable part of the torque is constant and does not decrease with speed.
It may happen that during the deceleration process when voltage decreases the motor torque
abruptly falls below load torque (instead of smoothly decreasing speed to zero), thus closing the
valve and causing water hammer.
Curves 1, 2 and 3 eliminate the water hammer phenomenon. In pump applications the load
torque decreases in square relation to the speed, thus correcting control of voltage to reduce
torque adequately and to smooth deceleration to a stop.
Note:
• It is recommended that STOP CURVE 0 be used for all standard applications (not pumps).
• To reduce water hammer, select STOP CURVE 1, then 2, then 3 in that order.
89
Stop Parameters
When stopping with a D.O.L starter speed is quickly reduced and flow
abruptly stopped. This may cause a
Water Hammer (mechanical shock
and audible noise) with severe
damage to pipes, joints, fittings,
valves, etc.

• Using two starting characteristics, the starter will accelerate to
DA-IV reaching 100% current limit. After Tx (Imm. Relay delay)
voltage to terminal 8 is switched off, using the standard
characteristic to complete acceleration. Useful to prevent initial
high acceleration. (Applications: Submersible pumps, Drum

Usage of D.ADJ.:GENERATOR PARAMETERS mode:
• The D.ADJ.:GENERATOR PARAMETERS must not
always be used when a diesel generator is supplying
the RVS-DN. Only use D.ADJ.:GENERATOR
PARAMETERS when the normal starting process fails,
i.e. SHORTED SCR or WRONG CONNECTION faults
occur, and only after you have tested and are sure
that the SCRs, motor and motor connections are not
faulty.
99
D.ADJ.:GENERATOR PARAMETERS
To operate D.ADJ.:GENERATOR PARAMETERS mode:
• Set dip switch # 3 and dip switch #1 to on
• Insert a contact (or jumper) between Control Supply and
input terminal 8 (DUAL ADJUST) and close contact to
operate the D.ADJ.:GENERATOR PARAMETERS. Dual
Adjust LED will light.
• Set the DUAL ADJUST parameters to the values
necessary for the application (e.g., shorter

* Control voltage to the electronic circuitry is derived from three phase supply
* Connect Neutral to terminal 3 to enable Phase Loss Protection (when
Neutral
is not available or not connected to Terminal 3 starter may not detect
Phase Loss
of lightly loaded motors.
* Use “dry contact” between terminals 1&2 to start/stop the soft starter.
* Do no apply start/stop signal to terminals 1&2 simultaneously with voltage
