Motor Protection:
Too Many Starts Maximum number of starts, range: Off or 1-10, during a time period 1-60 min.
Starts inhibit Period of 1-60 min, during which starting is prevented, after Too Many Start
fault.
Long Start Time (Stall protection) Maximum allowable starting time 1-30 sec. (1-250sec. in WIDER SETTINGS)
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 (after internal delay).
Electronic Overload (I
2
t) Adjustable IEC and MEMA curves.
Under Current Trips when current drops below 20-90% In, time delay 1-40 sec.
Under Voltage* Trips when main voltage drops below 50-90%, time delay 1-10 Sec
Over Voltage Trips when main voltage increase above 110-125%, time delay 1-10 sec.
Phase Loss, Under/Over Frequency* Trips when one or two phases are missing and frequency is 45Hz. or 65Hz.
Phase Sequence Trips when phase sequence is wrong
Shorted SCR or Wrong connection 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.
External fault Trips when an External Contact closes for 2 sec.
* With optional Auto Reset.
