8.1. Fault List
[Table 10. Fault List]
FAULT MESSAGE DESCRIPTION & CONDITION 발생원인
[FAULT-02]
"SENSOR HIGH"
Sensor output is above ADC max. value.
Defective sensor module or transmitter
board ADC
[FAULT-03]
"SENSOR LOW"
Sensor output is below ADC min. value.
Defective sensor module or transmitter
board ADC
[FAULT-04]
"EEPROM ERROR"
Defective Transmitter EEPROM Checksum Defective Transmitter Board EEPROM
[FAULT-05]
"+24V LOW"
It occurs when 24 V main input power is inputed
with voltage below 10 V. Input power below 10V or defective Transmitter
ADC
[FAULT-06]
"ADC FAIL"
Defective Transmitter ADC Defective Transmitter ADC
[FAULT-07]
"H/W REVISION"
H/W Version Error Defective MPU inside Transmitter
[FAULT-08]
"SENSOR HUNTING"
When there is repeated hunting error in gas
measurement sensor output status may be poor or check
for input power noise.
8.2. Recovery List
[Table 11. Recovery List]
No CAUSE SOLUTION
1 Defective Sensor Module Change Sensor
2 Defective Transmitter Board ADC Change Transmitter Board
3 Defective Transmitter Board EEPROM
1) Perform Factory Initialization then correct parameter and re-calibrate
2) Change sensor unit when the same problem occurs again
4 Defective MPU inside Transmitter Change Transmitter Main Board
5 Poor Sensor Output Status Change Sensor
6 Check Input Power Noise Check External Input Voltage Noise Status
