Run 1
(green)
| ON
| Channel 1 active:
- process data contain valid analog value
|
OFF
| Channel 1 not active:
- Calibration is performed, analog value in the process data not current (frozen or zero)
- or channel 1 is switched off (if LED error 1 not lit)
|
Error 1
(red)
| ON
| - Analog value of channel 1 is above the valid measuring range, specified through register R21 of channel 1. Bit SB1.1 is set in the status byte of channel 1.
- Analog value of channel 1 is below the valid measuring range, specified through register R22 of channel 1. Bit SB1.0 is set in the status byte of channel 1.
- Calibration is in progress. The LED goes out when the calibration is complete.
|
OFF
| - Analog value of channel 1 is within the valid measuring range (if LED Run 1 is lit)
- or channel 1 is switched off (if LED Run 1 is not lit)
|
Run 2
(green)
| ON
| Channel 2 active:
- process data contain valid analog value
|
OFF
| Channel 2 not active:
- Calibration is performed, analog value in the process data not current (frozen or zero)
- or channel 2 is switched off (if LED error 2 not lit)
|
Error 2
(red)
| ON
| - Analog value of channel 2 is above the valid measuring range, specified through register R21 of channel 2. Bit SB2.1 is set in the status byte of channel 2.
- Analog value of channel 2 is below the valid measuring range, specified through register R22 of channel 2. Bit SB2.0 is set in the status byte of channel 2.
- Calibration is in progress. The LED goes out when the calibration is complete.
|
OFF
| - Analog value of channel 2 is within the valid measuring range (if LED Run 2 is lit)
