Chapter 5—Troubleshooting

Basics of Troubleshooting
Chapter 5 describes corrective measures you should take if you encounter a problem when using
an ATEC.
You are not required to do any controller troubleshooting. You may wish to contact your local
Siemens Building Technologies, Inc., Siemens representative if a problem occurs or you have
any questions about the controller.
NOTE: When troubleshooting, record what the problem is 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 Building
Technologies representative.
Datamate Software
Datamate is a customer software tool for all controller communications. There are two versions:
Datamate Base, and Datamate Advanced. Datamate Base works on an IBM-compatible Personal
Computer or a Handheld PC or Pocket PC™ running Windows CE. Datamate Advanced works
only on an IBM-compatible Personal Computer. With Datamate, you can back up, restore, and
edit any APOGEE database (but only Datamate Advanced allows you to edit points offline).
Backing up and restoring a database can be accomplished while connected to any APOGEE field
panel, or to the Building Level Network (BLN) or Floor Level Network (FLN) device in question. A
modem and telephone lines can also be used. Databases can be saved to a hard or floppy disk
and kept for permanent storage or used as backup.
For more information regarding Datamate software, see the appropriate user guide based on
which version of Datamate you are using (Base or Advanced), or contact your local Siemens
Building Technologies representative.
Basic Service Information
Always remove power from the controller when installing or replacing it. Since the controller does
not have a power switch, the recommended method of removing power from a locally powered
controller is to turn OFF the power to the 24 Vac transformer. The recommended method of
removing power from a controller on a power cable (even to service a single controller) is to turn
OFF the power at the transformer.
NOTE: When removing power from 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.
Never remove the cover from the ATEC. There are no serviceable parts inside. If a problem is
found with a controller, contact your local Siemens Building Technologies representative for
replacement. An anti-static wrist strap is recommended when installing or replacing controllers.
