stage. When none of the stages are active, the user can configure the default stage to command the
LED in various ways as long as none of the stages remain inactive.
The control sources that can be used to command each of the four stages are listed in section 1.10
Table 7. The control sources available for the dual LED output consist of the same control source
options as Table 8 with the addition of controller fault options to drive the LED. Hence, the dual LED
can be configured to be driven when a (selected) fault occurs.
The output types available for the dual LED for each stage are listed in Table1 below

Table 2: LED Response Options
In ‘
Normal On/Off’
response type, the output command state will follow the control input command:
when the control input command is ON, the output will be turned ON and vice-versa.
In
‘Blinking Logic’
response type, the output will toggle at a period of ‘
Digital Blink Rate
’ for as long
as the input command is ON.
The
Control Source
setpoint together with
Control Number
setpoint determine which signal is used
to drive the LED of that stage. For example setting
Control Source
to ‘
CAN Receive’
and
Control
Number
to ‘
1
’, connects signal measured from CAN Receive 1 to the stage in question. The input
signal is scaled per input type range between 0 and 1 to form control signal.
