1929 ! Mezzanine-module ID inva‐
lid
FID DPM Detector PIC: The mezzanine-
module ID value is not supported by this
DPM board. More specifically, the
module value is pointing to a non-initial‐
ized EEPROM region on the DPM.
This may indicate an invalid mezzanine
module or an older revision of the DPM
that was manufactured before the mez‐
zanine module was defined.
Verify the DPM revision level and re‐
place as needed.
Replace the mezzanine module on the
DPM.
1930 ! Mezzanine-module ID re‐
served
FID DPM Detector PIC: The mezzanine-
module ID value is set to a value re‐
served for future expansion.
Verify the DPM revision level and re‐
place as needed.
Replace the mezzanine module on the
DPM.

! Balance Failure TCD [L; U]
%5 on %4
TCD DPM Detector PIC: For Rev 1
TCD DPM: A detector balance sequence
failed because of a hardware failure, an
improper configuration, or sequence of
events. Some possible causes include:
The detector beads are too unbalanced
to be 'balance-able'. The detector signal
is not stable enough and proper balance
could not be obtained before the maxi‐
mum number of iterations was reached.
The A/D or D/A do not work properly. The
detector is not configured for acquisition
or turned off. SIMULATE_TCD_x is set
to ‘1’ (the detector cannot be balanced in
detector simulation mode).The balance
is disabled (DISABLE_BAL‐
ANCE_TCD_x is set to ‘1’). The sampling
period was changed during the balance
sequence.

? Balance Out Of Limit TCD
[L; U] %5 on %4
TCD DPM Detector PIC: For Rev 1 TCD
DPM: A detector balance value is
above the normal limits. The balance
may still work as this is an early warning.
If associated with a balance failure
(alarm 1957), 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
schedule maintenance to replace the
detector beads.
If using Rev 2 TCD DPM or FID DPM,
contact Customer Support.

! 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.
