Mounting and wiring
The EL9227-xxxx has illuminated push-buttons!
The illuminated push-buttons allow the overcurrent protection terminal to be operated, e.g. switch-
ing on and off and resetting the respective output. They are also used for programming and query-
ing the nominal current. There are 3 modes: operation mode, programming mode and query mode.
There is a common programming mode in which the two outputs can be set simultaneously, as they
are interdependent for the terminal with sum current limitation.
Overview of the 3 operation modes:
Operation mode
The operation mode is active as soon as the overcurrent protection terminal is supplied with supply voltage,
the initialization has been successfully completed and no other mode is active. This is effectively the normal
mode of operation.
Programming mode
The programming mode is available for the adjustable overcurrent protection terminals. To enter this mode,
press and hold one of the two buttons in operation mode for > 3 seconds. In programming mode, both
outputs can be set simultaneously.
Query mode
The query mode exists for the fixed overcurrent protection terminals, which are not adjustable. If
programming is disabled for the adjustable overcurrent protection terminals, only the query mode is
available. No changes can be made in query mode, i.e. it is only intended for querying the nominal current
value. To enter this mode, press and hold one of the two buttons in operation mode for > 3 seconds.
For operation in the respective modes, please refer to the table LED buttons Operation / Programming.
