Sample programming
 | The EL922x devices have illuminated push-buttons! The illuminated push-buttons allow the overcurrent protection terminal to be operated, e.g. switching on and off and resetting the respective output. They are also used for programming and querying 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. |
1. Press button LED 1 or button LED 2 for >3 seconds to enter the programming mode.
2. The Ready LED lights orange and indicates that they are in programming mode.
3. The green flashing code of button LED 1 indicates the nominal current still set for channel 1, button LED 2 indicates the nominal current still set for channel 2. Flashing once means 1 A, flashing twice 2 A, flashing three times 3 A, etc… Non-flashing indicates OFF.
4. The programming mode is exited automatically if no entries have been made after 45 seconds, in which case the settings made previously are not saved. In other words, the previously saved settings are retained.
5. The nominal currents are changed by entering the absolute current values.
I.e. 1 x press button LED 1 or 2 = 1 A, 2 x press = 2 A, 3 x press = 3 A, …, 10 x press = 10 A, press more than 11x press = OFF!
For variants up to 4 A, press more than 5x press = OFF!
6. Press button LED 1 or button LED 2 for >3 seconds to save the new settings, exit programming mode and the new values are active.
| 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 "online". |

| The EL9227-5500 / EL9222-5500 devices have 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. |
