LED Display
K-bus power ON Power supply (5 V) available on the K-bus
(green)
OFF No power supply (5 V) available on the K-bus
K-Bus Run ON Data transmission on the K-bus is active
(green)
OFF Data transmission on the K-bus is not active
Run 1 ON Channel 1 active:
(green)
• 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 ON
• Analog value of channel 1 is above the valid measuring range, specified through register R21 [} 50] of
(red)
channel 1. Bit SB1.1 [} 44] is set in the status byte of channel 1.
• Analog value of channel 1 is below the valid measuring range, specified through register R22 [} 50] of
channel 1. Bit SB1.0 [} 44] 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 ON Channel 2 active:
(green)
• 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 ON
• Analog value of channel 2 is above the valid measuring range, specified through register R21 [} 50] of
(red)
channel 2. Bit SB2.1 [} 46] is set in the status byte of channel 2.
• Analog value of channel 2 is below the valid measuring range, specified through register R22 [} 50] of
channel 2. Bit SB2.0 [} 46] 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)
• or channel 2 is switched off (if LED Run 2 is not lit)
Limiting the measuring range
The terminal indicates any violation of the measuring range to the higher-level controller via the status byte.
If the current measured value is:
• greater than specified in register R21 [} 50], bit 1 is set in the status byte,
• smaller than specified in register R22 [} 50], bit 0 is set in the status byte.
In both cases, the ERROR LED of the respective channel will be on. This display can be disabled through bit
R32.8 [} 50].
