Faults
E041 CH1 Partial Depletion
E091 CH2 Large difference between the detectors, i.e. one very dirty. This alarm will come up
if there is a difference of 3:1 between the detectors. Remove sensor and clean
sensor fingers. The probe sensor units (PSU) will be set to 16000 or 32000 if
turbidity. If this message persists, please consult with your supplier.
E141 CH3
E042 CH1 Full Depletion
E092 CH2 Attenuation too high or the real probe signal goes above 14000. The probe sensor
units (PSU) will be set to 16000. If this message persists, please consult with your
supplier.
E142 CH3
E043 CH1 Sensor User Offset At Limit
E093 CH2 The last Sensor Offset Calibration was out of limits, check sensor condition and
connections and repeat calibration. If the message persists please consult with
your supplier.
E143 CH3
E044 CH1 Sensor User Slope At Limit
E094 CH2 The last Sensor Slope Calibration was out of limits, check sensor condition and
connections and repeat calibration. If the message persists please consult with
your supplier.
E144 CH3
E045 CH1 Sensor User Slope < Spec
E095 CH2
The last Sensor Slope Calibration was less than the recommended specification,
check sensor condition and connections and repeat calibration. If the message
persists please consult with your supplier.
E145 CH3
E046 CH1 Sensor User Slope > Spec
E096 CH2 The last Sensor Slope Calibration was greater than the recommended specification,
check sensor condition and connections and repeat calibration. If the message
persists please consult with your supplier.
E146 CH3
E047 CH1 Sensor Open Circuit
E097 CH2 The sensor input is at open circuit, check sensor condition and connections. If the
message persists please consult with your supplier.
E147 CH3
E048 CH1 Sensor Short Circuit
E098 CH2 The sensor input is at short circuit, check sensor condition and connections. If the
message persists please consult with your supplier.
E148 CH3
E049 CH1 Sensor Positive Saturation
E099 CH2 The sensor input is greater than the maximum measurable input level, Check
Sensor condition and connections. If the message persists please consult with your
supplier.
E149 CH3
E050 CH1 Sensor Negative Saturation
E100 CH2 The sensor input is less than the minimum measurable input level, Check Sensor
condition and connections. If the message persists please consult with your
supplier.
E150 CH3
E051 CH1 Sensor Input Over Range
E101 CH2
The sensor reading is greater than the specified upper limit, check channel settings,
Sensor condition and connections. If the message persists please consult with your
supplier.
E151 CH3
E052 CH1 Sensor Input Under Range
E102 CH2 The sensor reading is less than the specified limit, check channel settings, Sensor
condition and connections. If the message persists please consult with your
supplier.
E152 CH3
