When SmartWire-DT supply voltage U
SWD
is applied, all LEDs will light up
once as part of an LED test. The green
Ready
LED is used to indicate the
device's general status, while external faults (process faults: overcurrent,
imbalance, phase failure) are indicated with the red
ERR
LED.
Whenever the red
ERR
LED indicates an external fault, the device will be in a
safe, switched-off state, and it will be necessary to carry out an error
acknowledgement in order to leave this state (
acknowledgment”, Page 62). If there are any internal electronic motor starter
faults, the
ERR
LED will light up with a continuous light, in which case it will
not be possible to reset the fault. Finally, the green
L
and
R/ON
LEDs are
used to indicate whether the motor is running in a counterclockwise or
clockwise direction. Since EMS-D... DOL starters only run in one direction,
the
L
LED is not used in them.
1.5.4 Motor current setting
The “Motor current 5” setting dial can be used to set the motor current. In
addition, sealable cover 2 can be used to prevent tampering with this setting.
The “Motor current” setting dial can be used to select any one of 16 discrete
motor current values. The dial‘s positions, as well as the currents that
correspond to them, are shown below:

combinations and what they stand for, please refer to
Section 3.2, “Device status”, Page 60.
