State LEDs¶
During the power ON procedure, the module initializes automatically. All LEDs (except the channel LEDs) are ON during this time.
| LED | State | Color | LED = OFF | LED = ON | LED flashes |
|---|---|---|---|---|---|
| Inputs 00…07 | Analog input | Yellow | Input is OFF | Input is ON (brightness depends on the value of the analog signal) | – |
| Outputs 00…07 | Analog output | Yellow | Output is OFF | Output is ON (brightness depends on the value of the analog signal) | – |
| UP | Process voltage 24 VDC via terminal | Green | Process voltage is missing | Process voltage OK | – |
| CH-ERR2 | Channel error, error messages in groups (analog inputs or outputs combined into the groups 2 and 4) | Red | No error or process voltage is missing | Severe error within the corresponding group | Error on one channel of the group |
| CH-ERR4 | Red | ||||
| CH-ERR *) | Module error | Red | – | Internal error | – |
| *) Both LEDs (CH-ERR2 and CH-ERR4) light up together | |||||
