Motor current and connection Starter current ≥ motor FLA ! ! ! 85 41

Motor current and connection In line/Inside delta When soft starter is connected “inside delta” lower current is running through the soft starter. Soft starter MUST Be connected exactly as shown in the manual 85 41

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” 85 41

Start Parameters SOFT START CURVE 0 (STANDARD) SOFT START CURVE 1 !! SOFT START CURVE 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 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. 83 83

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. SOFT START CURVE 0 (STANDARD) SOFT START CURVE 1 !! SOFT START CURVE 2 !! SOFT START CURVE 3 !!

Start Parameters SOFT START CURVE 0 (STANDARD) 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. SOFT START CURVE 1 !! SOFT START CURVE 2 !! SOFT START CURVE 3 !! SOFT START CURVE 4 (TORQUE) Time Torque Peak over speed (Torque) acceleration IV Tn Time = t1 Time < t1 Time > t1 Slight time increase smoothes the Peak Linear Torque increase Ideal Conditions 83 83

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 voltage according to the START PARAMETERS settings. Note:There is no PULSE START function when RVS-DN is connected Inside Delta. Un time sec. 83 83

Start Parameters INITIAL VOLTAGE 30% 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 % FLA when INITIAL CURRENT is reached INITIAL CURRENT 100% 10% Initial Voltage 50% Un 83 83

Start Parameters INITIAL CURRENT - determines initial Ramp-Up starting Current. When needed, increase Initial Voltage to Max. (over the 50% or 80% respectively). The LCD displays INITIAL CURRENT and the starter will linearly Ramp Up the current following the desired acceleration time. INITIAL CURRENT 100% Current I init.(100%) Imax (400%) Time Linear Current increase Ideal Conditions Start time 83 83

Start Parameters CURRENT LIMIT 400% OF FLA CURRENT LIMIT - determines the maximum current during acceleration process and the acceleration time to full speed.

Start Parameters ACC. TIME 10 SEC. ACCELERATION TIME - Determines the Voltage Ramp-up Time, from Initial to Full Voltage. Adjustable :1-30 (90) sec. Set to the shortest acceptable time. Time Voltage Ramp-up Time Un U start 30 (90) sec 1 83 83

Start Parameters MAX. START TIME 30 SEC. MAX. START TIME - Preventing Stall condition, trips the starter if current is not reduced below Motor FLA within the adjusted time. Adjustments: 1-30 (250) sec. Max. Starting Time Starting Current 20 10 30 83 83

Start Parameters NUMBER OF STARTS 10 STARTS PERIOD 30 MIN. START INHIBIT 15 MIN. Limits the NUMBER OF STARTS during the period of time defined by STARTS PERIOD. If you try to start even one more time within that period the START INHIBIT period will take effect. During the START INHIBIT period the WAIT BEFORE RST XX MIN message will be displayed. Adjustments: NUMBER OF STARTS – 1-10, OFF STARTS PERIOD, START INHIBIT min. 83 83

Stop Parameters SOFT STOP CURVE SOFT STOP CURVE 0 (STANDARD)
1 !! SOFT STOP CURVE 2 !! SOFT STOP CURVE 3 !! SOFT STOP CURVE 4 (TORQUE) 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. 83 83

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. SOFT STOP CURVE 0 (STANDARD) SOFT STOP CURVE 1 !! SOFT STOP CURVE 2 !! SOFT STOP CURVE 3 !! SOFT STOP CURVE 4 (TORQUE) DOL opens Un Speed 83 83

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). This may cause abrupt stalling instead of smoothly decreasing speed to zero, creating the Water Hammer phenomenon SOFT STOP CURVE 0 (STANDARD) SOFT STOP CURVE 1 !! SOFT STOP CURVE 2 !!

Stop Parameters FINAL TORQUE 0 (MIN.) FINAL TORQUE - Determines torque towards the end of a soft stop. If the current still flows after speed is softly reduced to zero, you should increase the FINAL TORQUE setting.

Dual Adjustment DA: INIT. VOLT. 30% DA: INIT. CURRENT 100% DA: CUR. LIMIT 400% OF FLA DA: ACC. TIME 10 SEC. DA: DEC. TIME DA: MOTOR FLA 31 AMP. Two sets of parameters - for Variable Loads, Two Speed Motors and D.ADJ.:GENERATOR PARAMETERS 83 83

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.

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.

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.).

Adjustments: Alarm Level: Mohm Trip Level: Off, Mohm Applications Submersible pumps Harsh environments Motors not running for a long period of time. INSULATION ALARM OFF INSULATION TRIP OFF S 83 83

Fault Parameters The RVS-DN can be automatically reset for UNDER VOLTAGE and PHASE LOSS faults. To start the motor after UNDER VOLTAGE and PHASE LOSS faults have been cleared, remove the START signal and recommence the signal. Note: AUTO RESET function has a non-programmable time delay of 60 seconds. AUTO RESET NO 83 83

Protection Under/Over Frequency
Operational when the RVS-DN is energized and protects the motor when the frequency is less than 45 or greater than 65Hz. Phase Loss Operational when the RVS-DN is energized, provided this protection has not been de-activated. Phase loss protection trips the RVS-DN when 1 or 2 phases are missing for more than 1 sec. Phase Sequence Operational when the RVS-DN is energized, provided this protection has not been de-activated. Phase sequence protection trips the RVS-DN when phase sequence is wrong. 83 83

Protection Wrong Connection
Operational after start signal. Trips if motor is not properly connected to the RVS-DN’s load terminals, when internal disconnection is detected in the motor winding. This protection is not active when D. ADJ.: GENERATOR PARAMETERS is selected. C R 400V 83 83

Protection Shorted SCR
Trips the RVS-DN if one or more of the SCRs have been shorted. This protection is not active when D. ADJ.: GENERATOR PARAMETERS is selected. Heat-Sink Over Temperature Thermal sensors are mounted on the heat-sink and trip the RVS-DN when the temperature rises above 85ºC External Fault External Fault becomes operational when RVS-DN is energized. The RVS-DN will trip if contact closes for more than 2 sec. 83 83
