1)
Without inserted jumper (SJ).
2)
With AC load voltage and inserted jumper (SJ). No residual current if the jumper (SJ) is not installed.
3)
The sum of all inrush currents on a ballast connected to an output must not
Note
The residual current of an RC quenching element connected to IEC Type 1 inputs may
cause unwanted signal st
ates. Remove the SJ jumper to rectify this fault.
Configuration in RUN
Special considerations must be given if you use the Configuration in RUN function.
SF LED is lit:
Status before re-configuration diagnostics on, SF LEDs lit among others (on CPU, IM or
module), although diagnostics are no longer pending and the module is operating correctly.
Solution:
● Only change the configuration when no diagnostics are pending for the module or
● Pulling and plugging the module.
