Shorted Field Wire Detected; Namur Sensor Failure Detected; Input Saturation Detected - GE Mark VIeS System Manual

2690-2721
Description IOPoint [ ] - Shorted field wire detected
Possible Cause A short circuit has been detected at the terminal board, based on the sensor type.
Solution Digital Input:
• Check the wiring between the terminal board and the device.
• Verify that the recommended line monitoring resistors are being used (refer to the I/O pack user documentation).
2722-2753
Description IOPoint [ ] - NAMUR Sensor Failure detected
Possible Cause Detected NAMUR sensor operation is outside its two normal current levels (between 1.0 mA and 2.2
mA)
Solution Digital Input:
• Check the wiring between the terminal board and the sensor.
• Check the sensor for proper operation.
• Replace the NAMUR device.
2754-2785
Description IOPoint [ ] - Input Saturation detected
Possible Cause An internal component's valid input range was exceeded. This could be due to the following reasons:
• Input signal equal to or exceeds the valid input range for the input type (improper sensor connected, sensor failure)
• Open-circuit field wiring
• Internal hardware failure
Solution
• Current Input: check field wiring and verify that the input source is between -11 V and 20 V (or 80 mA).
• Voltage Input:
− For ± 5 V input, check field wiring and verify that the input source is between -11 V and 20 V.
− For ± 10 V input, check field wiring and verify that the input source is between -11 V and 22 V.
• RTD Input:
− For MINCO_CA type, check for open circuits in the field wiring and then verify that the input source is between
-78.125 mV and 78.125 mV.
− For all other RTD types, check field wiring and verify that the input source is between -1.25 V and 1.25 V.
• TC Input: check field wiring and verify that the input source is between -625 mV and 625 mV.
• Digital Input:
− For externally wetted inputs, check field wiring and verify that the input source is between -11 V and 20 V.
− For internally wetted inputs, check field wiring and verify input source is between -11 V and 20 V.
• Pulse Accumulator (PA) Input: check field wiring and verify that the input source is between -11 V and 22 V.
