Maintenance, Service, and Troubleshooting 6-27
Problem
Cause
Suggested Action
Sheath Flow Warning
Sheath flow has been changed
in the last 30 seconds, and is
stabilizing
Allow sheath flow to stabilize, do not take
measurements during this time.
Sheath Pressure Error
Absolute pressure sensor is
measuring outside of allowable
range (17 to 128 kPa).
The allowable operating pressure range of the
instrument is 70 to 125 kPa. Operation outside of this
range may result in inaccurate measurements and
damage to internal components.
Absolute pressure sensor is not
functional.
Return instrument to TSI for service.
DMA Not Detected warning
DMA is not attached.
Attach DMA with auto recognition capabilities (3081A,
3085A, or 3086). Manually select 3086 DMA from the
Hardware menu if the Model 3086 is mounted in the
alternate configuration.
DMA is attached but has not
been upgraded.
3081 DMAs must be upgraded to 3081A, and 3085
DMAs must be upgraded to 3085A. Upgrade kits can be
purchased from TSI.
DMA is attached and connected
but is not reporting valid
information.
Reseat the DMA to re-establish connectivity.
Memory chip has worn out and needs to be replaced.
Purchase a DMA upgrade kit which includes a new
base plate.
3086 DMA is attached and
classifier firmware has not been
upgraded
Update classifier firmware to latest version. See
Upgrading Firmware.
DMA Voltage Error
DMA Voltage Self-Check
Error
DMA Voltage Error: Voltage
output of internal HV supply is
not within 25V of HV setpoint
due to a short in DMA.
DMA Voltage Self-Check Error:
The high voltage self-check test,
automatically conducted at start-
up, has failed. The HV reading is
more than 25V off at 50V and/or
9750V.
There is a short in the DMA because it is dirty. Clean
the DMA. See Cleaning the DMA Electrodes.
The instrument has been operated outside of the
specified operational temperature range, resulting in
damage to the HV supply. Return instrument to TSI for
service.
The HV has not been calibrated for >1 year and is in
need of calibration. Return instrument to TSI for service.
Case Temp Error
The classifier internal case
temperature is > 50°C or < 5°C.
Operate the classifier within the specified operating
temperature range of 10°C to 40°C. Operation outside
of this range may result in inaccurate measurements
and damage to internal components.
Neutralizer Detection Error
Both 3077(A) and 3088 neutralizer
detected at the same time due to a
momentary switch fault.
Contact TSI.
Neutralizer Not Active
No neutralizer installed.
Install a neutralizer or bypass error.
3088 Neutralizer is detected but
not powered on and or enabled.
Power on and enable 3088 neutralizer.
3088 Maximum Hours
Exceeded warning
The Model 3088 Neutralizer is
installed and is reporting more
than 8760 operating hours.
The x-ray source is near the end of its useful life. Return
the 3088 to TSI for service.
3088 Neutralization Error
The Model 3088 neutralizer is
reporting an error and is not
neutralizing.
A hardware failure has occurred on the 3088
neutralizer. Contact TSI.
