Fault Logic and Reset Circuits
Upon operation of any protection, the starter locks in a fault mode, disabling thyristors firing. The proper fault
indication LED lights and the Fault contact closes.
To reset the starter, after the fault has been removed, press Reset button on starter's front panel or disconnect
Mains voltage.
WARNING!
When starter is operated by a maintained contact, resetting the fault will start
the motor immediately!
Do not use the Fault contact to trip an upstream contactor. When the Fault
Contact closes on fault and trips the upstream contactor, Mains voltage will be
disconnected, thus resetting the RVS-AX and the motor will restart
instantaneously (see Fault Resetting).

Starter selection tables for various voltage ratings.
1
The starter selection table below concern standard, 1500r.p.m. 50Hz,
three-phase motors.
2
These values are given for guidance and may vary according to motor
manufacturer and depending on the number of poles.
3
It is the user’s responsibility to make sure that motor’s FLA will never
exceed Starter’s FLC.
