Mode of Operation

This motor controller is intended
to be used to softstart/ stop 3­phase squirrel cage induction
motors and thereby reduce the
stress or wear on gear and
belt/chain drives and to give
smooth operation of machines.
Soft starting and or stopping is
achieved by controlling the
motor voltage. During running
operation the semiconductor is
bypassed by an internal electro­mechanical relay.

The initial torque can be adjust­ed from 5 to 50% of the nominal
torque.

The soft-start time can be ad­justed from 0.5 to 10 s and 0.5
to 20 s for the soft-stop respec­tively.

A green LED indicates supply.
The yellow LED is flashing dur­ing the ramping up or down.
After the ramping when the
semiconductors are bypassed
the yellow LED lights constantly.
The red LED is flashing when
the sequency is different from
L1-L2-L3 (only in -C10). If the
softstarter is overheated the red
LED is turned on constantly.

Alarm handling:

Over temperature: The RSE will
not start if the heatsink has an
internal temperature which is
exceeding approx 100°C. When
over temperature occurs while
the softstarter is not ramping (1)
or while the bypass Relays are
activated (2) the following will
happen:

1) The softstarter will not ramp
up and alarm relay is deacti­vated (contact open) - Reset
takes place when the temper­ature drops below the critical
level and only if the supply is
interrupted and reapplied.

2) The alarm relay will deactivate
(open) to indicate fault and
when the softstarter is not
ramping the softstarter will
react as described in 1).

Sequence: By wrong sequence
at connection of the power the
RSE will start normally but the
alarm relay will not activate.
(Contacts open).
