Sterling 060, 100 Advance PID Options mass flow setup, Sample Time once in Steady Window for FIFO

Advance PID Options (mass flow setup)

Sample Time once in Steady Window for FIFO

This is how often the control takes snap shots of the mass flow hopper and enters the number in the FIFO table. For quicker FIFO updates you would decrease this number. For a more stable process you would increase this number.

Steady System Limit

This is the allowable percent deviation around the median. The median will be half way between the re-fill set point and the hopper size set point. For material that varies in bulk density or does not flow consistently you may have to increase the limit.

Steady System Time Test

This timer is used to determine whether or not to show the Steady System flag on the main control screen. Rather than going in and out of stable, the process must remain stable for the set time and then the Steady System will be shown.

PID Timer

This is the amount of time that the blender will run without making a change to the auger speeds to adjust the blender though put i.e. pounds per hour.

PID Gain

The gain increase or decreases the size and speed of the adjustments made to the PID. A smaller number makes slower adjustments. A bigger number makes faster adjustments.
