STANDARD

HAND-OFF-AUTO (FIELD)

I. General Description This standard control feature provides for Hand-Off-Auto control mode selection via a three-position selector switch located at the process equipment, telemetry control panel (TCP), or motor controller.

II. Control Logic When the Hand control mode is selected, the associated equipment will operate continuously until the selector switch is returned to the Off or Auto position, or is shut down upon a hardwired safety interlock. When the Auto control mode is selected, the PLC control logic will be enabled.

III. Human Machine Interface The HMI will be located at the Ray Waterman control facility. A Hand-Off-Auto selector switch object will be included on the HMI screen. The selector switch object will indicate the current mode of control and provide a means for operator selection of the control mode.


STANDARD

HAND-OFF-AUTO (HMI)

I. General Description This standard control feature provides for Hand-Off-Auto control mode selection via a three-state selector switch object defined in the process control system HMI.

II. PLC Control Logic The PLC control logic will respond to the selection of the Hand-Off-Auto control modes made through the HMI. When the Hand control mode is selected, manual control features will be available through the HMI. When the Auto control mode is selected, the automatic control logic will be enabled.

III. Human Machine Interface The HMI will be located at the Ray Waterman control facility. A Hand-Off-Auto selector switch object will be included on the control panel. The selector switch object will indicate the current mode of control and provide a means for operator selection of the control mode.


STANDARD

SPEED CONTROL

I. General Description This standard control feature provides for manual adjustment of operating speed.

II. PLC Control Logic The PLC control logic will be defined to accept an operator-entered value to directly control the operating speed of process equipment. This feature will generally be available when the process equipment is being operated in the manual control mode.

III. Human Machine Interface The HMI will provide for operator adjustment of the speed parameter. The speed parameter will be ranged 0 to 100 percent of full speed.


STANDARD

POSITION CONTROL

I. General Description This standard control feature provides for manual adjustment of operating position.

II. PLC Control Logic The PLC control logic will be defined to accept an operator-entered value to directly control the operating position of a control valve. This feature will generally be available when the valve is being operated in the manual control mode.

III. Human Machine Interface The HMI will provide for operator adjustment of the position to full open, or full closed.


STANDARD

FLOW TOTALIZATION

I. General Description This standard control feature provides for totalization of process variables that represent flow.

II. PLC Control Logic The PLC control logic will be defined to generate a totalized value for all process variables that represent flow. A program file will accept flow values from the flow transmitter communicated through Modbus protocol. The totalized value will be reported to the HMI in units to be selected by the end user. Totalizer values will be maintained in the PLC for the current day and previous day. Totalizers will be conditioned to accumulate flow only when the pump or valve controlling the flow condition is operating or open. This will prevent the accumulation of zero-drift error.

III. Human Machine Interface Each of the daily totalizer values will be available through the HMI.


STANDARD

RUNTIME ACCUMULATOR

I. General Description This standard control feature provides for accumulation of runtime hours for all process equipment that the run status is monitored by the process control system.

II. PLC Control Logic The PLC control logic will be defined to monitor process equipment run status and generate a runtime hour accumulator value. A program file triggered by a selectable time interrupt will monitor the process equipment run status. The selectable time interrupt will be set for one second. Each time the program executes and the process equipment run status is true a second will be added to a runtime seconds accumulator. When the seconds accumulator equals 3600, a hour will be added to the runtime hour accumulator. Four individual runtime accumulators will be maintained for each equipment item. These accumulators are defined as follows:

Current Day: Current day’s runtime. Previous Day: Previous day’s runtime. Total: Non-resettable accumulator indicating total runtime. Maintenance: Resettable accumulator indicating runtime between maintenance activities.

III. Human Machine Interface The process equipment runtime hour accumulator will be available through the HMI.


STANDARD

FAIL TO OPERATE

I. General Description This standard control feature monitors process equipment to insure the equipment is operating properly in response to a control command.

II. PLC Control Logic The PLC control logic will be defined to monitor the operational status of the process equipment and generate an alarm condition if the operational status does not reflect the commanded state of the equipment. For example, if a pump is commanded to run and the pump run status is not proven within 5 seconds a fail to run alarm will be generated.

III. Human Machine Interface A fail to operate alarm will be defined for process equipment controlled and monitored by the process control system.


STANDARD

TIME BASED

I. General Description This standard control feature provides for time-based control of process equipment.

II. PLC Control Logic The PLC control logic will be defined to operate the process equipment on a timed interval basis. Upon expiration of the time interval, the process equipment will be operated for a prescribed duration.

III. Human Machine Interface The HMI will provide for operator adjustment of the operating interval and duration. The HMI will also display the time expired for both the operating interval and duration.

VI-A. Well Pump - Remote Control Description A. In the Local mode of operation, the pump will operate continuously at an operator-

selected speed made through the operator interface keypad located on the VFD.

B. In the Remote mode of operation, the well pump will be operated and its speed regulated at an operator-adjustable speed setpoint through the HMI.

C. The pump shall be shut down in either mode of operation if any of the following conditions occur:

1. High discharge pressure (XXpsi, increasing) as indicated by PSH 101 or PSH 117. Indication of a high disharge pressure condition shall initiate an operator-adjustable time (timing relay located in TCP) duration.

2. VFD fault condition.

3. Pump run timer relay trip.

4. Well facility power failure.

D. The pump shall be shut down in the Auto mode of operation if the following events occur:

1. Low well level as indicated by LT 101 or LT 117.


PROCESS EQUIPMENT


E. Pump run time and number of starts shall be indicated on elapsed time meters and counters on the front of Telemetry Control Panel (TCP).

VI-B. Pressure Regulating Valves (Well Pump) - Control Description A. The pressure regulating valves operate in response to the well pump discharge pressure.

There are no hardwired controls associated with the open or close control of the pressure regulating valves. The pressure regulating valve will open when the pump pressure exceeds the pressure regulating valve setting. The pressure regulating valve Open position will be monitored by limit switch ZSH 101 or ZSH 117. Indication of a pressure regulating valve Open position will initiate the waste timing sequence.

VI-C. System Control valves (Well Pump) - Remote Control Description A. In the Hand mode of operation, the valve position will be operator-selected.

B. In the Auto mode of operation, well pump startup will cause the pressure regulating valve to Open, and the system control valve (CV 101 or CV 117) shall remain closed. The pump shall pump to waste for an operator-adjustable time (timing relay located in TCP) duration. At the expiration of the pump to waste time duration, the system control valve will be called to open, and the pressure regulating valve will close in response to the drop in pressure. If the system control valve fails to obtain the commanded position within an operator-adjustable time duration (initially set at XX seconds, through the HMI), a “Well Supply Valve Problem” alarm condition shall be annunciated through the HMI. If the pressure regulating valve fails to close after an operator-adjustable time (timing relay located in TCP) duration a “Waste Valve Open to Drain” alarm condition shall be annunciated through the HMI. All waste sequence control logic shall be implemented with hardwired relay logic.

C. The system control valves shall return to the closed position when the well pump is shut down.
