8.5 Power and Alarm Status LED Colors
• When the top LED is green, the controller is powered up. See Figure 8-2 on the previous page.
• When the top LED is out, there is no input voltage to controller.
• If the bottom LED is red:
• There are devices still in the controller database but no longer at the site.
Manually remove devices.
• Devices are not being accessed. See Sections 6.1 and 6.2.

• Verify suffi cient voltage level. On the controller menu bar, go to Help→About. Voltage level should
be close to 24 Vdc.
• Test the actuator in isolation. See Section 5.
