The Damper Trouble Detection module determines the trouble status of the damper control within VAV applications. This module provides position detection for VAV dampers and also provides an indication of failure due to the damper not opening or closing properly. This module is used for UL 864 UUKL Smoke Control support to validate the VAV damper is in the commanded position. This module monitors the Damper Percent Cmd and outputs a Trouble warning after the specified Delay under the following circumstances:

  • The flow is not near zero if the damper is commanded closed.

  • The flow is not near maximum if the damper is commanded to 100%.
