590+ Series DC Digital Converter
Selecting Local or Remote Control
The default is for the
L/R
key to be set for Remote control, i.e. both the SEQ and REF LEDs will
be off.
If the default Remote Start/Stop and Speed Control is not suitable for your application, follow
the instructions below using the Operator Station or a suitable PC programming tool to select
Local Start/Stop and Speed Control.
Note:
You can only change between Local and Remote control when the Converter is
“stopped”.
The
L/R
key on the Operator Station toggles between
Local
and
Remote
control, changing both
Start/Stop and Speed Control modes at the same time
.
LED Indications
The mode of control is indicated by the
“LOCAL” LEDs on the Operator Station:
SEQ = Start/Stop
REF = Speed Control
If the LED is illuminated (
●
), then LOCAL
mode is in force.
Reading the Status LEDs
These LEDs are used when the blanking cover is fitted
to the drive instead of the Operator Station.
