Form designation:

Form 1

This product was tested for compliance with IEC 60947-4-2 for class A equipment.
Start-Stop Parameters:
Starter Current:

ASTAT-XT’s rated current according to its nameplate.

Motor Current:

Motor Full Load Ampere (Im) 50-125%

8

of Starter Current.

Start/Stop 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.

Kick Start Duration:

A pulse of 80% Un, for an adj. time 0.1-1 Sec, for starting high friction loads

Starting Voltage:

10-50% Un (5-80%

9

)

Initial Current:

100-400% In. A single current control starting curve. It appears when Starting
Voltage

is displayed, the up arrow is pressed and Starting Voltage has

reached its max.

Current Limit:

100-700% of Motor Current

Ramp UP Time:

1-30 Sec (1-90 sec

9

)

Ramp DOWN Time:

1-30 Sec (1-90 sec

9

)

DUAL Settings Parameters: Secondary start stop characteristic for: Starting Voltage, Starting Current, Current

Limit, Ramp UP, Ramp DOWN and Motor Current.

Energy Saving:

Energy save for lightly loaded motors

Slow Speed Torque:

Torque while motor is at 1/6 nominal speed

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

9

)

Over Current (JAM Fault):

Three trip functions:
At all time - If I > 850% of Starter Current it trips the ASTAT-XT within 1 cycle
(overrides the value of the O/C – JAM Delay setting).
At starting process - If I > 850% of Motor Current it trips the ASTAT-XT after O/C
JAM Delay (see here after)
At run time - If I > O/C – JAM Fault setting of Im it trips the ASTAT-XT after O/C
JAM Delay

Electronic Overload:

Can be set as IEC Class 10, 20 or NEMA Class 10, 20 or 30.
Can be set to operate at all times, disabled or operate during Run only.

Under Current:

Trips when current drops below 20-90% of Motor Current, time delay 1-40 sec.
Optional auto reset after time delay.

Under Voltage:

Trips when main voltage drops below 120-600V, time delay 1-10 Sec. Optional Auto
Reset.

Over Voltage:

Trips when main voltage increase above 250-750V, time delay 1-10 sec.
