Troubleshooting

This chapter describes corrective measures you can take should you encounter a problem when using the Fume Hood Controller. For issues not covered in this section, contact your local Siemens Building Technologies, Inc. representative.

You are not required to do any controller troubleshooting. Contact your local Siemens Building Technologies, Inc. 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, Inc. representative.

Basic Service Information

Always remove power to the controller when installing or replacing it. Since the controller does not have a power switch, the recommended method of removing power to a locally powered controller is to turn OFF the power to the 24 Vac transformer. The recommended method of removing power to 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 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.

Never remove the cover from the controller. 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.

Preventive Maintenance

Most controller components are designed so that, under normal circumstances, they do not require preventive maintenance. However, devices that are exposed to dusty or dirty environments may require periodic cleaning to function properly. To ensure optimum system performance, it is recommended that you discuss the operating requirements of your application with your Siemens Building Technologies, Inc. representative to determine the best service support program for your needs.
