MSA S5000 - Table 17 Troubleshooting - Sensor Faults

Fault Code Latch Description Action
reference power supply to
HART modem circuity is
faulty.
problem persists.
F016 (Not used,

N/A N/A N/A
F017 Magnet User
Button Fault
Non-Latch This fault indicates that the
EZTouch user button is
constant on or faulty.
Verify there is no magnet left on the
unit front window nor magnetic field
present right next to the unit window.
Return the User Interface Module to
the factory or authorized service
center if the problem persists.
F101/F201 Sensor
Missing Fault
Non-Latch This fault occurs when the
sensor is disconnected or
wiring is faulty or damaged.
Check the wiring and sensor
connection.
F102/F202 Sensor
Supply Voltage Fault
Non-Latch This fault occurs when the
power supply to the sensor is
faulty.
Check the wiring and sensor
connection.
F103/F203 Invalid
Sensor Parameters in
Main EEPROM Fault
Latch This fault occurs when the
sensor parameters stored in
the main EEPROM is
incorrect.
Check the sensor parameters,
including calibration level, full scale,
warning and alarm set points. Correct
any mis-configured parameters.
F104/F204 Sensor
Element Fault
Non-Latch This fault occurs when the
sensor sensing element is
faulty or damaged.
Check the wiring and sensor
connection. Replace the sensor if
needed.
F105/F205 Sensor
Heater Fault
Non-Latch This fault occurs when the
sensor heater is faulty or
damaged.
Check the wiring and sensor
connection. Replace the sensor if
needed.
F106/F206 Other
Sensor Internal Fault
Non-Latch This fault occurs when the
sensor has other internal
faults.
Check the wiring and sensor
connection. Replace the sensor if
needed.
F107/F207 Sensor
Internal Data CRC Error
Fault
Non-Latch This fault occurs when the
internal data of the sensor has
CRC error.
Replace the sensor.
F108/F208 Sensor EOL
Fault
Non-Latch This fault occurs when the
sensing element of the sensor
is at the end of life state.
Replace the sensor.
F109/F209 Sensor
Blockage Fault
Non-Latch This fault occurs when the
sensor gas sensing path
and/or opening is blocked.
Clean out any debris or foreign objects
blocking the sensing path/opening.
For more details, see 6.1 IR Sensor
Cleaning Procedure or 6.3 Clearing a
Blockage, depending on sensor type.
F110/F210 Negative
Drift Fault
Latch This fault occurs when the
sensor has severe negative
Re-calibrate the sensor. Replace the
sensor if this fault persists.
