7200 Monitor Instruction Manual
20 Error Messages
When the instrument detects an error condition, an error message will be displayed. All the error messages are
described below. Certain error/fault conditions can be used in the fault setup of the alarms and analogue output and
are identified by a *.
20.1 Sensor
No Sensor *
No sensor detected on input to monitor if sensor is connected and wiring is okay either sensor fault or monitor fault.
Sensor Low Limit *
Sensor input signal is too low possible, sensor fault.
Sensor High Limit *
Sensor input signal is too high possible, sensor fault.
20.2 Measure Mode
Display Over Range *
Calculated display value greater than selected display range maximum, either change display range or check
calibration is correct.
Display Under Range *
Calculated display value is less than selected display range minimum, check calibration.
20.3 Self Clean Sensors
Clean Fault *
During a clean cycle the sensor detected a fault. Inspect sensor for damage and/or excess fouling – if there is no
evidence of this remove and reapply power to the monitor and observe the clean operation.
Clean Time Out *
The clean cycle took too long to complete. Inspect sensor for damage and/or excess fouling – if there is no evidence
of this remove and reapply power to the monitor and observe the clean operation.
Service Sensor *
Sensor requires servicing (clean count is greater than service life). Service sensor then use reset clean count to zero
clean count and clear the service sensor fault.
Std Error *
The standardise sensor reading is outside of the allowed limits. Check sensor for excess fouling, scratched/damaged
glass tubes or other damage. If nothing is found remove and reapply power to the monitor and use manual clean to
activate a clean cycle. If the fault reoccurs, contact Partech technical support for assistance.
