PROBLEM AND ERROR CODES (TB82)
N - 17
Table N-1. Problem Codes of TB82 Transmitter
Code
Description
Corrective Action
BA.CHKS Incorrect or missing 3-k
Ω
Balco temperature sensor
checksum
Cycle transmitter power.
Remove transmitter from installed location and relocate to
noise-free environment. If problem does not appear, transmitter
needs new final location or additional shielding on transmitter
and/or wiring.
Contact ABB.
BA.F.CAL Out of range or missing
factory calibration for 3-k
Ω
Balco temperature sensor
Contact ABB for factory calibration procedure. Calibrate temper-
ature sensor for short-term usage until factory calibration can be
performed.
BAD.SEE Bad SEEPROM or
pH/ORP/pION input PCB
assembly
Input PCB assembly factory calibration constants can not be
loaded. Calibrate sensor and order replacement pH/ORP/pION
input PCB assembly. Existing assembly should properly function
until new assembly is received.
BLNK.UP Blank microprocessor
EEPROM
Cycle transmitter power.
Contact ABB.
GND LP
Ground loop present or
shorted sensor cable
Verify sensor wiring connections.
Verify sensor does not have any exposed wire from nicks, etc. If
it does, repair (if possible) or replace.
Remove any liquids, oils, scales or corrosion from transmitter ter-
minal block or extension cable junction box terminals.
Verify sensor responds to pH buffers. Replace sensor and/or
sensor extension cable (if present) if sensor does not respond.
Electronically test sensor (refer to the product instruction).
Replace if it does not meet requirements.
HI.C.CKT Cable diagnostic circuit
failure - high range error
Verify sensor wiring connections.
Remove any liquids, oils, scales or corrosion from transmitter ter-
minal block or extension cable junction box terminals.
Electronically test sensor. Replace if it does not meet
requirements.
Input PCB assembly diagnostic circuit failure exists. Disable
diagnostics and order replacement input PCB assembly. Existing
input PCB assembly should properly function until new assembly
is received.
HI.CA.AD Cable diagnostic signal
above transmitter A/D range
Input PCB assembly diagnostic circuit failure exists. Disable
diagnostics and order replacement input PCB assembly. Existing
input PCB assembly should properly function until new assembly
is received.
HI.EFF
High sensor efficiency
(>110%)
Verify proper buffer values were used for calibration and repeat
buffer calibration.
Clean sensor and repeat buffer calibration.
