5.11 E-BAM Error Displays, Error Logs, and Error Codes
This section provides information about routine maintenance of the E-BAM, and for performing
more detailed diagnostic tests if a problem is encountered. The E-BAM often generates error
messages on the display or in the data log if a failure or other problem is detected. Many times,
there is a simple solution, but persistent errors often signify a failure which will require investigation.
The E-BAM error codes are described in this section.
In the event a measured parameter or sequence is not within design specifications, the E-BAM will
generate an alarm. These alarms can be monitored via the alarm log, output files or the alarm relay.
A list of alarms is detailed in Table 5-4.
Code Description Cause
1 Tape Break No tape movement was detected during the tape move process.
2 Beta Detector
The event occurs when the Beta detector count rate is less than
500 Hz during the sampling cycle.
4 Sensor Range
The event occurs when an analog sensor reading (AT, RH, BP,
UPPER, LOWER, FT, FRH) is outside the designated limits.
8 Tape Advance
The event occurs when the pressure drops across the tape
exceeded the Tape Advance Pressure setting.
16 Flow Failure
The event occurs when the sample flow is less than 1.0 LPM for
greater than 1 minute.
The event occurs when the sample flow is +/-10% out of
regulation for 1 minute.
The event occurs when the sample flow is +/-5% out of regulation
for 5 minutes.
32 Nozzle Failure
The event occurs when the nozzle failed to move and stop at the
up or down position.
The event will also occur when the foil device is still inserted at
start of operation.
64 Digital Link Failure
The event occurs when communication with the 597A sensor has
ceased for greater than 10-seconds.
128 Power Failure The event occurs for a power cycle or a micro-processor reset.
256 Short Sample The event occurs when the first sample cycle is less than 1-hour.
512 Maintenance The event occurs when the user stops normal operation.
Table 5-4 The E-BAM Alarm Conditions
An alarm is indicated and logged at the time it occurs. The resolution time is not recorded. See
section 0 for an explanation of viewing alarms through the E-BAM panel display.
Note : If multiple errors or alarms occur in the same data period, then the logged alarm code will be
the sum of the two individual code numbers. This is a rare occurrence.
