6.4.10 Power Supply
The Power Supply is a 24 Volt 1.3 Amp Power Supply used to provide power to the optional Communi-
cations Modules and Operator Interface, MNR-0049. It is not standard in all models.
6.5
Alarms
The following paragraphs describe the warning and alarm conditions that are monitored and controlled
by the Electrical Panel.
6.5.1
Final Separator Warning
The high pressure-breathing compressor is equipped with a final separator. This is a stainless steel ves-
sel, approximately 3¾ inch diameter, located on the purification panel. To prevent fatigue failure of this
vessel, the PLC program monitors the pressurization and depressurization cycles of this separator and
will first issue a Warning, and then later an Alarm function.
The program is set up for a 90% warning and a 100% shutdown alarm for this counter feature. The pro-
gram would be configured to reflect the following values when it is built.
When the warning is displayed, the unit will still continue to function properly, but will prompt the
operator to contact Bauer Compressors to make arrangements to replace the separator. When the Alarm
level has been achieved, the compressor will no longer function, and will require the replacement of the
separator. When this is accomplished, the unit can be reactivated by making adjustments to the PLC
software. Please contact Bauer Product Support for detailed instructions.
