PLC Warning and Alarm Lamps
2.6.4.1.1
Warning Lamp - Amber
The Warning Lamp is a LED lamp for long trouble free life. This lamp will flash a code IAW the logic
of the PLC. See Paragraph 2.7.
2.6.4.1.2
Alarm Lamp - Red
The Alarm Lamp is a LED lamp for long trouble free life. This lamp will flash a code IAW the logic of
the PLC. See Paragraph 2.8.
2.6.5
Hourmeter
The panel is supplied with an hourmeter. The hourmeter is not resettable and used to monitor the run
hours of the compressor. It is powered with a 120 VAC signal supplied from the auxiliary contact on
the motor starter.
2.6.6
PLC Control
This panel will be controlled with a Telemecanique 16 I/O Twido Programmable Logic Controller. This
unit will provide logical operations to the overall system that includes the high pressure compressor,
purification systems, and other accessories.
2.7
Warnings
The amber Warning Lamp located on the control panel flashes warning codes with a 0.5 second on, 0.5
second off sequence with a distinct pause between sequences. In addition the light will illuminate on
initial start up for a period of 5 seconds, to serve as a lamp test function. The lamp is a LED lamp for
long trouble free life.
2.7.1
One Flash - Final Separator Warning
The compressor unit is equipped with a final separator. To prevent fatigue failure of this pressure ves-
sel, the PLC program monitors the pressurization, de-pressurization cycles of the separator and will
first issue a Warning, and then an Alarm. The program is set up to provide the 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 Final Separator.
When the Alarm level has been achieved, the compressor will no longer function, and will require the
replacement of the Final Separator. Once the Final Separator is replaced, the unit can be re-activated by
making adjustments to the PLC. Please contact Bauer Product Support for detailed instructions on this
procedure.
