Control Supply ....................................110-230V (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 wires, squirrel cage induction motor.
Connection type................................... Standard 3 wire U, V, W connection, or 6 wire “Inside Delta” (Programmable)
Start-Stop Parameters:
Starter FLC..........................................Starter’s Full Load Current, according to Selector Guide
Motor FLA...........................................Motor Full Load Ampere 50-100% of Starter FLC
Starting Curve 0 (Standard).................2 Standard Starting and stopping curves.
Pump Control Curves (1!, 2!, 3!) ........6 field selectable curves preventing Over-pressure during start and Water
Hammer during stop.
Torque Control Curve (4)....................2 Selectable curves preventing Over-pressure during start and Water Hammer
during stop. In addition, these curves may be used for Torque control starting of
constant torque applications.
Pulse Start Duration .....A pulse of 80% Un, for an adj. time 0.1-1 Sec, for starting high friction loads
Initial Voltage......................................10-50% Un (*10-80%), 5% - by special order
Initial Current .....................................100-400% In (1 Current Control starting Curve, appears when Initial Voltage is
............................................................. displayed , “Up” arrow is pressed, and IV% has reached its Max.)
Current Limit.......................................100-400% of Motor FLA (*100-500%)
Acceleration Time ............................... 1-30 Sec (*1-90 sec)
Deceleration Time ...............................1-30 Sec (*1-90 sec, not in Dual Adjust)
Dual Adjustments ................................Secondary start stop characteristic for: Motor FLA, Initial Voltage, Current Limit,
Acceleration Time and Deceleration Time.
Energy Saving .....................................Energy save for lightly loaded motors
Slow Speed Torque .............................Torque while motor is at 1/6 nominal speed
Tacho and Linear Acceleration .......... 12 field selectable curves – defining gain control, improving Tacho Feedback.

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, when 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 200-850% In, both within 1 Cycle.
Electronic overload (I
2
t) ...................... Adjustable 75-150% of motor FLA, adjustable Trip time at 500% In of 1-10 sec.
Under current.......................................Trips when current drops below 20-90% In, time delay 1-40 sec.
Under voltage** ..................................Trips when main voltage drops below 120-600V, time delay 1-10 Sec
Over voltage ........................................Trips when main voltage increase above 150-750V, time delay 1-10 sec.
Phase loss, Under/over Frequency** ..Trips when one or two phases are missing or frequency is < 40Hz or > 65Hz.
Phase sequence....................................Trips when phase sequence is wrong
Long slow speed time..........................Trips if operating at slow speed for more than 1-30 sec (*1-250 sec)
Wrong connection ...............................Prevents starting, trips if motor is notconnected / incorrectly connected to the
starter.
Shorted SCR ........................................Trips in case one or more SCRs have been shorted
Heat Sink over temperature.................Trips when heat-sink temperature rises above 85˚C.
External fault .......................................Trips when an External Contact closes for 2 sec.
Motor Insulation (optional................Alarm level setting 0.2 – 5M, trips when insulation decreases below 0.2-5M
Motor Thermistor (optional) ..............Trip level setting 1-10K, trips when resistance decreases below the set level.
* Special settings – Consult Factory
** With optional Auto Reset.
