13,800V, 15,000V (consult the factory for other voltages) + 10%-15%
P.I.V ratings ...............................Not less than 3 times rated voltage
Frequency .................................45 – 65 Hz (with frequency automatically change)
Control Supply ...........................110-230V 50/60Hz(to be specified) +10% - 15%
110VDC, 125VDC, 220VDC (to be specified) +10% - 15%
Control inputs & Outputs ...........Either same as Control Supply or by special order 24-230V AC/DC (to be
specified)
Load ..........................................Three phases, three wire, squirrel cage induction motor.
Synchronous motor with asynchronous starting characteristics.
Start-Stop Parameters:
Starter FLC ................................Starter Full Load Current according to Selector Guide
Motor FLA ..................................Motor Full Load Ampere 33-100% of starter FLC
Pump Control Curves ................6 field selectable curves including torque control curve preventing over-
pressure during start and water hammer during stop.
Pulse Start Level and Duration ..Adjustable level of pulse, for an adjustable time 0-10 Sec, for starting high
friction loads or holding constant current level.
Initial Voltage .............................10-50% Un (*5-85%)
Initial Current .............................for current ramp
Current Limit ..............................100-400% of Motor FLA (*100-700%)
Acceleration Time ......................1-30 Sec (*1-90 sec)
Deceleration Time .....................0-30 Sec (*0-90 sec)
Dual Adjustments ......................Secondary start stop characteristic for: Motor FLA, Initial Voltage, Current
Limit, Acceleration Time and Deceleration Time.
Tacho and Linear Acceleration ..12 field selectable curves – defining Tacho Feedback gain improving linearity.
Motor Protection:
Too many starts .........................Maximum number of starts range Off or 1-10, during a time period 1-60 min.
Starts inhibit ...............................Time period 1-60 min, where starting is prevented, after too many starts fault.
Long start time (Stall protection) Maximum allowable starting time 1-30 sec. (*1-250 Sec).
Over current (Shear-pin)............Two operation functions: during starting trips the starter at 850% and during
running at 100-850% In, both within 1 Cycle.
Electronic overload……………..According to IEC class 5, 10, 15, 20, 25 or 30 OR according to NEMA class 5,
10, 15, 20, 25 or 30.
Under current ............................Trips when current drops below 20-90% In with time delay of 1-40 sec.
Under voltage** .........................Trips when main voltage drops below 50-90% of Un. Time delay 1-10 Sec
Over voltage ..............................Trips when main voltage increases above 110-125% of Un.
Time delay of 1-10 sec.
Phase loss .................................Trips when one or two phases are missing.
Phase sequence****. .................Trips when phase sequence is wrong.
Wrong connection & Shorted SCR…
Prevents starting, trips if motor is not connected / incorrectly connected to the
starter or in case one or more SCRs have been shorted.
Heat-sink over temp. .................Trips when heat-sink temperature rises above 85˚C.
