Service Information
This section describes corrective measures you can take if you encounter a problem
with a PXC Compact Series controller.
If you encounter a symptom or a problem not covered in this manual, contact your
Siemens Industry representative.
NOTE:
When removing power to a controller to perform maintenance or service, make sure
that the person in charge of the facility is aware of this and that appropriate steps are
taken to keep the building in control.
NOTE:
When troubleshooting, record the problem and what actions were performed
immediately before the problem occurred. Being able to describe the problem in detail
is important should you need assistance from your local Siemens Industry
representative.
To view the status of the PXC Compact and to call up reports for troubleshooting, you
can use an operator's terminal and the operator interface or an Insight workstation. For
more information, see the following documentation:
● APOGEE P2 ALN Field Panel User's Manual (125-3019) or the APOGEE BACnet
ALN Field Panel User's Manual (125-3020) (125-3019 or 125-3020).
● Insight
Revision 3.x Documentation . To view this documentation, see the Insight
Online Documentation window, which you can access from the Insight Main Menu
or the Insight program group.
It is good practice to back up the PXC Compact database routinely and whenever
changes are made to the database or new equipment is added.
While performing the troubleshooting procedures outlined in this manual, you may wish
to refer to the APOGEE Wiring Guidelines for Field Panels and Equipment Controllers
(125-3002).
