Spectros SF-ExplorIR - Fault Codes

Fault Codes
FAULT CODES ARE ADDITIVE. For example: A fault code of <0003> indicates that both a Box
Temperature Fault <0001> and a Bench Temperature Fault <0002> have occurred.
<0001> Box Temperature Fault: Enclosure temperature is outside normal range (or IR detector has
failed). Check that the monitor is not being subjected to extreme temperatures. Use the DIAG function to
check the Box Temperature.
<0002> Bench Temperature Fault: Optical bench is outside normal operating range (or IR detector has
failed). Check that the monitor is not being subjected to extreme temperatures.
<0004> Manifold Pressure Fault: The manifold pressure is outside its normal operating range (or IR
detector has failed). Enter the DIAG function and record ALL data. Call the factory with this information
for further instructions.
<0040> Fill Flow Fault: The purge-air bag’s pressure drop is outside expected limits. Check for a
punctured bag or disconnected tubing.
<0080> Over Range Fault: Monitor exposed to a gas level that exceeded 100 ppm.
<0100> Zero Filter Fault: The air-purge bag is contaminated with gas. Take monitor to a clean-air area
and use the EMTYBAG and FILLBAG functions to decontaminate the air-purge bag.
<0200> Gain Set Fault: The digipot autotune sequence has failed. This fault will only occur on first boot up
or after a firmware upgrade. Call the factory for further instructions.
<0400> A/D Fault: A fault has occurred in the analog-to-digital circuitry. Contact the factory with this
information for further instructions.
<0800> Sample Flow Fault: Check for: A restriction in the gas-sample inlet or exhaust; a blocked internal
filter; or a failed pump.
<1000> Purge Flow Fault: Check for: A restriction in the gas-sample exhaust; a blocked internal filter;
or a failed pump. Once the purge air stream has been restored, the monitor will return to normal
operation after it completes a purge cycle.
<2000> Bag Fill Fault: The purge-air bag did not fill within the expected time allotment. Check for a
punctured bag or disconnected tubing.
<4000> Zero Range Fault: The IR detector’s output voltage is out of tolerance. Enter the DIAG function
and record ALL data. Call the factory with this information for further instructions.
<8000> Clipping Fault: The detector voltage may be out of tolerance. Use the DIAG function to check the IR
detector voltage. Call the factory with this information for further instructions.
