Energy save for lightly loaded motors
Torque while motor is at 1/6 nominal speed
Maximum number of starts, range: Off or 1-10, during a time period 1-60 min.
Time period 1-60 min, when starting is prevented, after too many starts fault
Maximum allowable starting time 1-30 sec. (1-250 Sec
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
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.
Trips when current drops below 20-90% of Motor Current, time delay 1-40 sec.
Optional auto reset after time delay.
Trips when main voltage drops below 120-600V, time delay 1-10 Sec. Optional Auto
Reset.
Trips when main voltage increase above 250-750V, time delay 1-10 sec.
