2.8.5 Five Flashes - Carbon Monoxide Monitor (Optional)
The compressor system may be equipped with an optional Carbon Monoxide Monitor. This consists of
an electronic module that samples the compressed air supply. The unit will provide a continuous dis-
play of the CO level in PPM, parts per million. If the CO level becomes excessively high, then the red
alarm light on the face of the monitor will illuminate. At the same time the alarm relay in the CO Mon-
itor which is connected to the PLC I4 will generate a CO ALARM condition.The compressor will shut-
down, the I4 lamp will illuminate, and the alarm code will flash.The unit should be calibrated with a
test gas monthly. Refer to the chapter titled CO Monitor for this procedure.
2.8.6 Six Flashes - Final Separator Shutdown
The high pressure-breathing compressor is equipped with a final separator. To prevent fatigue failure of
this vessel, the PLC program monitors the pressurization, de-pressurization cycles of the separator and
will issue a Warning, and then later an Alarm. The program is set up to provide a warning at 90% of the
maximum recommended number of cycles. The program is configured to reflect these values when it is
built. When the warning is illuminated, the unit will still continue to function properly, but will prompt
the operator to contact Bauer Compressors for making arrangements to replace the separator. When the
Alarm level has been achieved, the compressor will no longer function, and will require the replace-
ment of the separator. Once this is accomplished, the unit can be re-activated by making adjustments to
the PLC. Please contact Bauer Product Support for detailed instructions
2.8.7 Seven Flashes - Condensate Fault (OPT)
The optional compressor condensate level float switch is located in the condensate collection tank.
Under normal operating conditions, the switch is open and the I6 lamp on the PLC is off. On a high
condensate level the float switch will close, the compressor will shutdown, the PLC I6 lamp will illumi-
nate, and the alarm code will flash. The operator should drain the condensate from the tank and resume
operation of the equipment.
2.8.8 On Steady - Motor Starter Overload Trip
The compressor overload relay is located in the electrical enclosure, directly beneath the motor starter.
The relay is Normally Open and is not connected to the PLC, but is connected directly to the red Alarm
Light. Under normal operating conditions, the switch is open. On an Overload Trip of the motor, the
compressor will shutdown, and the Alarm Light will be illuminated steady (no flash sequence).
^ WARNING
Do not attempt to override the Final Separator Shutdown. This feature is
provided to protect operating personnel from injury or death.
NOTICE
The compressor condensate contains some oil, and accordingly, should be dis-
posed of in accordance with state and local regulations.
