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%
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%
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
)
Ramp DOWN Time:
1-30 Sec (1-90 sec
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
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.
