7.8.2 Equipment Totalizer Faceplate
Pressing any totalizer field provides access to change the reset the totalized value and start/stop the totalizing function. (Figure 7-18). The
mass flow controllers, base, feed, and media pumps have totalizers for tracking gas and liquid delivery.
NOTE:
Displayed totalizers for the media, base and feed pumps, and the MFCs are reset and restarted during the Initialize Phase. If the
user stops a totalizer after this reset, it must be manually restarted to operate.

7.8.3 Proportional, Integral, Derivative (PID) Loop Faceplate
Figure 7-19 is the PID (Extended PID) control loop faceplate used to change control loop modes, change loop setpoints (when in Operator
mode) and to configure and tune the control loop. Each of the main control loops (pH, DOs, temperatures) has one of these faceplates.
NOTE:
All PID loops can be run in Operator Auto and Manual modes from the PID faceplate. The temperature loops are configured from
the faceplates while the two DO loops and the pH loop are configured from the Configuration Buttons (Section 7.9).
