Selector Guide – How to Select?

• System voltage– Motor current and connection– Starting conditions– Options and control voltage

• System voltage– 400 230 - 400 VAC, 50/60Hz, +10% -15%– 480 480 VAC, 50/60Hz, +10% -15%– 600 600 VAC, 50/60Hz, +10% -15%– 690 690 VAC, 50/60Hz, +10% -15%– 1000 1000 VAC, 50/60Hz, +10% -15%

Models: 105A, 170A, 210A, 310A, 390A, 460A.

19


• Motor current and connection– Starter current ≥ motor FLA

! ! !

20


• Motor current and connection– In line/Inside delta

• When soft starter is connected “inside delta” lower current is running through the soft starter.

Soft starte

r MUST

Be connected exactly

as shown in th

e manual

21


• 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”

22


• Starting conditions– The RVS-DN is able to start at 4xIn, 30 seconds

at 50°C

23


• Options:• Communication - RS-485 (Modbus)• Communication – Profibus• Insulation tester• Analog card – Thermistor in and Analog out• Harsh environment treatment.• Preparation for Bypass contactor• Line and load bus bars at bottom • Remote panel mounting replacing the original panel.• Russian characters LCD display• Marine approval• UL & cUL approval• Tachometer card for special drive systems

24

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.

• 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).

• 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

Note: • The O/C SHEAR PIN is not intended to

replace the fast acting fuses, required to protect the thyristors.

STATISTICAL DATA

75

Start Parameters

• 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.

3 !!SOFT START CURVE4 (TORQUE)

76

Start ParametersWhen 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

Start Curve 4 (Torque) – Torque Controlled acceleration, provides a smooth time controlled torque ramp for the motor and the load (pump).

Note - Always start with Start Curve 0. If towards end of acceleration, peak torque is too high (pressure is too high), proceed to Curve 1, 2, 3 or 4 if necessary.

79

Start Parameters

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 voltage according to the START PARAMETERS settings.

Note:There is no PULSE START function when RVS-DN is connected Inside Delta.

80

Start Parameters

INITIAL VOLTAGE - determines the Initial Torque (the Torque is reduced in the square proportion of the voltage reduction).

Note: When INITIAL VOLTAGE is set its maximum value, this displays changes to INITIAL CURRENT.

• Adjustments:– 10-50% (80%) Un, should be set so

that motor starts turning immediately after Start signal initiated

Stop Parameters

• 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.

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.

Stop Parameters

Stopping with a standard soft starter - when pumping to a higher elevation, motor torque may quickly fall below load torque (as torque decreases at the square of voltage reduction).

Dual Adjustment

• 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 fans with resonating frequency, etc).

D.ADJ.:GENERATOR PARAMETERS

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.

100


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 ACCELERATION TIME, lower CURRENT LIMIT, etc.).
