The Current N/A Counter reduces each time the plunger does not arrive during the On Time. Once the present counter reaches 0 the well will be shut-in. Any Fast or Good Arrival will automatically reset this counter to the Initial No Arrival value. 23 SYNC MODE: This is a special mode used when synchronized timing is required to reduce interference with other wells in the same gathering system. Sync Mode enables constant cycles to be programmed, even with Auto-Cycle adjustments. To enable Sync Mode, select YES from the display. This will allow the Flow Time to be entered on the next line (#24). 24 FLOW TIME: This is the total time that the sales valve can be on or open. It is generally equal to the On Time + Afterflow Time, but when used with the Auto-Cycle program, you can increase this time to allow for additional Afterflow. The Sync Mode must be set to YES for this function to be available. The following is an example of time settings when using Sync Mode and Flow Time. On Time: 30 minutes Afterflow Time: 15 minutes Flow Time: 1 hour (set by the operator for additional Afterflow) Off Time: 1 hour The total cycle time is Off Time + Flow Time = 2 hours. When the Controller begins operating, Afterflow Time is allowed to increase from the initial setting for fast arrivals up to the point that the sales valve is open for 1 hour (max. Flow Time). This can be variable due to the plunger arrival time. 25 PLUNGER CATCH MODE: This is a special mode used with a plunger catcher. When this mode is enabled and the plunger arrives, the RTU closes the valves and enters the Plunger Catch mode. This mode can be cleared by turning this mode off. 119 SHARED FLOW MODE: This is a special mode used to synchronize production for multiple wells into one production facility, one well at a time. When this mode is on, the HI DP DELAY and HI DP WAIT >= menu options are enabled. 120 HI DP DELAY: When Shared Flow Mode is enabled and the Differential Pressure is less than HI DP WAIT >=, this is the time the RTU will wait before opening the sales valve. 2913 Specialty Drive • P.O.

ACiC Operator’s Manual Revision 4 Page 25 of 95 ENABLE EARLY ARR: This enables a special arrival window that occurs prior to the Fast Arrival Window. When an Early Arrival occurs, both Current Early and Current Fast counters are reduced and Fast Adjustments are made. 27 EARLY TIME: This time setting creates the Early Window. From the start of the On Time to the Early Time value is the Early Window. A plunger arrival time less than the Early Time would be in the Early Window. 28 INITIAL EARLY: This counter is the initial setting for the Early Window. It determines how many consecutive Early Arrivals the well can make before shut-in occurs. The value will not change unless you modify the default setting. 29 CURRENT EARLY: This counter is the Current or Present count of plunger arrivals in the Early Window. The Current Early Counter is reduced each time the plunger arrives in the Early Window. Once the present counter reaches 0 the well will be shut-in. Any Fast or Good Arrival will automatically reset this counter to the Initial No Arrival value. 30 TANK DELAY: This is the delay time before the second motor valve is allowed to open. Tank Delay Time always starts timing at the beginning of the Tubing On Time. It is generally used to sell higher-pressure gas down the gas sales line before having to open to a lower pressure in order to surface the plunger. If the plunger arrives before the delay time expires the Tank On Time is bypassed. This option is only available if the Tank Control Mode is selected. 31 TANK ON: This is the total time the tank valve will be open (provided that the plunger has not arrived). The Tank On Time starts at the end of the Tank Delay Time. If the tank valve opens and the plunger arrives during the Tank On Time, the tank valve will close and the Tubing valve will either start the Afterflow cycle or shut-in (depending on the program status). This option is only available if the Tank Control Mode is selected. 102 RECVRY OFFT: This is a special Off Time used during LL3 recovery mode. The Recovery Off Time will run instead of the Off Time after the initial counts have been satisfied. 121 INIT RECVRY CNT: This counter is the initial setting for the LL3 Recovery Mode. It determines how many consecutive no arrivals the well can make before using the Recovery Off Time. The value will not change unless you modify the default setting. 2913 Specialty Drive • P.O.
