Log Break
When the Log Break option is enabled archive log-break will occur when the Orifice
plate size or other flow-related constant is changed.
Flow Control
Raise/lower Flow-rate control is achieved using a PID3TERM Module. The Flow
Controller uses a FLOW SETPOINT signal and the calculated flow rate signal as
inputs to the PID3TERM module, the output of which generates raise/lower pulses
on the discrete outputs (Raise on DO#1, Lower on DO#2).
Default settings are:
