PC17 LO.EFF 1) Verify the proper buffer values were used for
calibration and repeat buffer calibration.
2) Clean sensor and repeat buffer calibration.
3) Look for shorts in the sensor and extension cable,
if present. Remove all potential shorts.
4) Remove any liquids, oils, scales or corrosion from
TB84PH terminal block or extension cable junction
box terminals. Replace extension cable if
corrosion is present.
5) If sensor is functioning properly, order a new
sensor to replace existing sensor once the analyzer
does not accept calibration values.
PC18 HI.AO2 1) See PC6 corrective actions.
PC19 LO.AO2 2) See PC6 corrective actions.
PC20 BAD.SEE 1) Input PCB Factory calibration constants can not be
loaded. Calibrate sensor and order replacement
pH/ORP/pION Input PCB Assembly. Existing PCB
should properly function until new assembly is
received.
PC21 NO.F.CAL 1) Contact Factory for calibration procedure.
Calibrate sensor for short-term usage until factory
calibration can be performed.
PC22 BLNK.uP 1) Cycle analyzer power.
2) Contact Factory.
PC23 SEE.EMI 1) See PC22 corrective action.
PC24 ROM.EMI 1) See PC22 corrective action.
PC25 ROM.SUM 1) See PC22 corrective action.
PC30 PV.F.CAL 1) Contact Factory for calibration procedure.
Calibrate sensor for short-term usage until factory
calibration can be performed.
PC31 BA.F.CAL 1) Contact Factory for calibration procedure.
Calibrate temperature sensor for short-term usage
until factory calibration can be performed.
PC32 PT.F.CAL 1) See PC31 corrective action.
PC33 RZ.F.CAL 1) Contact Factory for calibration procedure.
Reference impedance diagnostic will not be
operational until factory calibration is performed.
Disable Di
agnostics until factory calibration can be performed.
PC34 PV.CHKS 1) Cycle analyzer power.
2) Remove analyzer from installed location and
relocate to a noise-free environment. If problem
does not appear, the analyzer will need a different
final location or additional shielding of the
analyzer and/or wiring is necessary for proper
function.
3) Contact Factory.
