Operating Controls
The Operating Controls include the Operator Control Panel (OCP), the Feed Flow Control Panel, the
Programmable Logic Controller (PLC), and several indicators and controls off of the OCP that require
occasional adjustment and monitoring for manual operation.
The OCP provides all of the push buttons, switches, alarm lights and displays needed for operator control
and monitoring of the system (see Figure 30).
Figure 30. Operator Control Panel (OCP).
The Feed Flow Control Panel (see Figure 31) controls the operation of Filtrate Flow Control Valve V-202
(see Figure 10), which controls the flow of filtrate from the MF system to the RO feed tank.
Figure 31. Feed Flow Control Panel.
The PLC provides automated control after operator startup and in response to operator switch selections.
The indicators and controls off of the OCP provide the operator with local indications of system conditions
and manual controls for certain operating functions of the TWPS. All the Operating Controls are identified
and described in detail in WP 0011, Description and Use of Operator Controls and Indicators.
