Behavior of the outputs when the settings are changed
If settings are changed during operation (outputs are switched on), the outputs remain switched on.
This has the advantage that the system can remain in operation and a change can be made "on-
line".
The EL9222-5500 has a sum current limitation of 10 A.
The 10 A can be split between the two channels. If one channel is set to 10 A, the other channel
must be set to OFF! If the sum current is exceeded, button LED 1 and button LED 2 flash red.
The flashing code shows how the channels have been set, and at least one channel must be
changed.
When the value falls below the maximum sum current again, button LED 1 and button LED 2 flash
green or are off. Only now can the programming mode be saved and exited.
