Status LEDs and status bits
Below is a table showing the meaning of the Status LEDs and Status bits for the power outputs (taking the EP9214 as an example):
The LED applies to both voltages/currents (Us and Up; OR).
LED | Status | Warning | Error | Description |
|---|---|---|---|---|
Off | 0 | 0 | 0 | The output is ready |
Green | 1 | 0 | 0 | The output is just switching on |
Green | 1 | 0 | 0 | The output is switched on. Normal operating state. |
Flashing green | 1 | 1 | 0 | The output is still operating, but will switch off if conditions remain unchanged (Warning Ux). |
Flashing red | 0 | 1 | 1 | The output has been switched off (Error Ux). Switching on again is not yet possible (waiting time of 20 seconds) |
Red | 0 | 0 | 1 | The output has been disabled and can be returned to a normal state by a reset. |
Red running light all channels | x | 1 | 1 | Undervoltage Us/Up or temperature error |
Initialization
When switching on the voltage supply to the EP9214 / EP9224, all green LEDs and then all red LEDs are switched on briefly to test the LEDs.
