Product description:
e So starter is 3 phase controlled and designed for
starting and running compressor motors. e so
starter has current controlled ramping up and by-pass
function.
e voltage control compensate for missing start
torque at starting up ramping. e current measure-
ment is also for I2t calculation for protection of the
motor. e motor protection has to be adjusted before
starting up.
e so starter has internal by-pass relays for bypass-
ing the semiconductors when the motor is in full
speed.
Any kind of failure cause stop and the so starter will
go into service mode until the failure is reset. e so
starter has also pause mode for protecting the
semiconductors against overheating.
Alarm indication is provided through a red LED which
signals the type of fault via a user-friendly ashing
sequence.
