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 |
|---|---|---|---|---|---|
| Outputs 0…7 | Digital output | yellow | Output = OFF | Output = ON 2) | – |
| UP | Process supply voltage 24 VDC via terminal | green | Process supply voltage is missing | Process supply voltage OK | – |
| UP3 | Process supply voltage outputs 0 … 3 24 VDC via terminal | green | Process supply voltage is missing | Process supply voltage OK | – |
| UP4 | Process supply voltage outputs 4 … 7 24 VDC via terminal | green | Process supply voltage is missing | Process supply voltage OK | – |
| CH-ERR3 | Channel Error, error messages in groups (digital outputs combined into the groups 3, 4) | red | No error or process supply voltage is missing | Severe error within the corresponding group | Error on in the corresponding group |
| CH-ERR4 | red | ||||
| CH-ERR 1) | Module Error | red | – | Internal error | – |
1) All of the LEDs CH-ERR3 to CH-ERR4 light up together 2) The state of the LEDs corresponds to the logic state of the output. In case of missing or low process supply voltage UP3 or UP4, the signal on the output terminal is off even though the LED is on. |
