Burn-out is a fail-safe setting, normally associated with
control equipment, but also used on monitoring devices like
recorders to indicate the loss of a valid input signal. For
controllers, burn-out drives the calculated output to a

condition that is considered safe for the process, typically
to a state where energy is not put into the process.

Burn-out is configured to go up scale (full scale), or down
scale (full scale).

For control purposes, when a signal that is a process
variable in a control loop goes full upscale, the
controller's output will drop to zero in a reverse action
controller.

Similarly, when a signal goes full scale down scale, a
controller's output will drop to zero in a direct action
controller.
