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:

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:

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.

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.

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.
