Loop Break is an additional safety feature intended to monitor the rate of
change of the process value, while approaching the SP1, if on the Sensor Menu
DRRh is selected, or SP2 if °F.°C is selected. It is strictly intended as an
additional warning system, therefore its use is entirely optional. An active Loop
Break will cause the Process Value digits to blink in a rotating pattern. If the
process value reaches the set point the blinking will stop and B.TIM is
completed successfully, otherwise BR.AL Break Alarm warning will flash, and
Output 1 will be turned off.

than the stated rate, flashing B.TIM will be displayed, the output will be de-
energized, and Alarm energized. Loop break time will be disabled when the
Process Value (PV) enters the control band.
Loop Break Alarm can work on the RH or Temperature function of the
