Error Message
Code
51 Zero gas calibration failed - zero
signal too low
52 Zero gas calibration failed - zero
signal too high
53 Span gas calibration failed - span
signal too low
54 Span gas calibration failed - span
signal too high
55 Gas calibration failed - sensor
lifetime exceeded. The sensor
sensitivity has fallen to below 50%
of its original value; please replace
the sensor.
56 Entered span gas concentration is
out of range - please edit and try
again
57 Operation failed; invalid object type
9. Problem Solving
Possible Cause
The level at which the
channel is trying to
calibrate zero is outside
the configured limits
The level at which the
channel is trying to
calibrate zero is outside
the configured limits
The level at which the
channel is trying to
calibrate span is outside
the configured limits
The level at which the
channel is trying to
calibrate span is outside
the configured limits
Touchpoint Pro monitors
the performance of mV
sensors relative to their
first span calibration.
If the gas response
falls below 50% of the
original value this error
occurs.
The span gas selected is
not within the configured
limits
There has been a
communication error
between the CCB and
COB

Remedial Action
1. For a mA channel, calibration should always be
done by forcing the output from the sensor where the
facility exists. Check the configured limits on zero and
span gas calibration and ensure that the forced mA
value is within the limits.
2. For a mA channel where the sensor has no facility
to force the output, consult the manufacturer's
instructions and carry out a calibration at the sensor.
3. For a mV channel, there may be a problem
with the sensor or the calibration gas. Consult the
manufacturer's instructions.

1. Contact your local service representative to
schedule a sensor replacement.
2. When the replacement sensor has been fitted,
repeat calibration in accordance with the instructions
in chapter 6, using the "First Span" function
1. Check the configured limits for span gas
concentration.
2. Obtain an alternative span gas that is within the
limits.
3. Retry the operation.
1. Please retry the operation.
2. If still unsuccessful, on the front panel, press the
Accept and Reset buttons together for 10 s, which
will restart the COB.
3. If the error has not cleared, if possible cycle the
power to the system.
4. If the problem persists, please contact your local
service representative.
