2258 ! Balance Failure TCD %5
on %4
FID DPM Detector PIC: A detector bal‐
ance sequence failed because of a hard‐
ware failure or because of an improper
configuration or sequence of events.
Some possible causes are:
The detector beads are too mismatched
to be balance corrected.
The detector signal is not stable enough
and proper balance could not be ob‐
tained before the maximum number of
iterations was reached.
The A/D or D/A do not work properly.
The detector is not configured for acquis‐
ition or turned off.
SIMULATE_TCD is set to ‘1’ (the bal‐
ance cannot be done in detector simula‐
tion mode).
The balance is disabled (DISABLE_BAL‐
ANCE_TCD is set to ‘1’).
The sampling period was changed dur‐
ing the balance sequence.
Contact Customer Support.
2259 ? Balance Out Of Limit FID
on %4
FID DPM Detector PIC: A detector bal‐
ance value is above the normal limits.
The balance may still work as this is an
early warning.
If associated with a balance failure
(alarm 2257), then the source of the
balance failure must be corrected.
If not associated with a balance failure
and the balance limits are normal
(greater than 9 Volts or 90%), schedule
maintenance to clean or replace the
FID detector.
2260 ? Balance Out Of Limit TCD
%5 on %4
TCD DPM Detector PIC: A detector bal‐
ance value is above the normal limits.
The balance may still work as this is an
early warning.
If associated with a balance failure
(alarm 2258), then the source of the
balance failure must be corrected. If not
associated with a balance failure and
the balance limits are normal (greater
than 9 Volts or 90%) then maintenance
should be scheduled to replace the de‐
tector beads.
2261,
2622
! The ADC missed a sample
on channel [1 - 2] on %4
A transient error was detected by the An‐
alog-to-Digital Converter of the DPM,
channel #n. The missing or invalid data
point was replaced by a point with a value
of zero.
Reset the DPM. If the error repeats, re‐
place the DPM.
2265 ? Flame Ignition Failure on
%4
FID DPM Detector PIC: The FID flame
could not be ignited within the predefined
delay (25 or 60 sec). No other attempt
will be made to automatically ignite the
flame until the MANUAL IGNITION DO
is activated.
If associated with an alarm 2225 (Glow
plug failure), then diagnose and fix that
alarm first. If a BASIC program is used
to control the electronic pressure con‐
troller (EPC) to adjust the gas mixture
for proper ignition, confirm that the poll
rate of the 'IGNITE' DI is set to 2 sec.
Verify adequate gas-supply pressure.
Verify the proper operation of the EPC.
