ACiC Operator’s Manual Revision 4 Page 30 of 95 PROPORTIONAL ADJ: Proportional Adjustments is a specific application that allows larger time adjustments as the arrival time deviates farther outside the Good Window. When a plunger arrival is in the Fast Window, more significant time adjustments may need to be made to decrease the Off Time and increase the Afterflow Time. Conversely, when a plunger arrival is in the Slow Window, more significant time adjustments may be needed to increase the Off Time and decrease the Afterflow Time. Figure 4.3: Depiction of Proportional Adjustments This is accomplished using a ‘ramp’ from the Fast Time to 50% of the Fast Window and a ‘ramp’ from the Slow Time to 50% of the Slow Window. The minimum adjustment in either window is 25% of the adjustment setting. This is graphically shown in Figure 4.3. AUTO RESTART: This option allows the RTU to restart in the automatic mode after a power failure if the mode was automatic before the power failure. CP OFF AF ONLY: This option directs the RTU to honor Casing Pressure Off Overrides only during Afterflow if on (YES). TP OFF AF ONLY: This option directs the RTU to honor Tubing Pressure Off Overrides only during Afterflow if on (YES). DP OFF AF ONLY: This option directs the RTU to honor Differential Pressure Off Overrides only during Afterflow if on (YES). HL OFF AF ONLY: This option directs the RTU to honor High-Line Pressure Off Overrides only during Afterflow if on (YES). LO BATT CLS TB: This option directs the RTU to close the tubing valve when it detects a low battery before shutting down. Enabling this option will disable LO BATT OPN TBG. LO BATT OPN TBG: This option directs the RTU to open the tubing valve when it detects a low battery before shutting down. Enabling this option will disable LO BATT CLS TBG. 2913 Specialty Drive • P.O. Box 130158 • Tyler, TX 75713-0158 • Phone: 903-561-4851 • Fax: 903-561-6567
ACiC Operator’s Manual Revision 4 Page 31 of 95 LO BATT CLS TANK: This option directs the RTU to close the tank valve when it detects a low battery before shutting down. This item is only applicable in Tank Control Mode. Enabling this option will disable LO BATT OPN TANK. LO BATT OPN TANK: This option directs the RTU to open the tank valve when it detects a low battery before shutting down. This item is only applicable in Tank Control Mode. Enabling this option will disable LO BATT CLS TANK. 63 SET PASSWORD: The password is a 4-digit number that can be set for data protection. Setting the password will prevent the ability to modify settings in the controller until the correct password is entered. Once a password is entered, it will remain in effect until the controller returns to the scroll list, either automatically or by pressing F6. MODEM STATUS: Modem status will display the integrated Modem Type, Mobile Data Number (MDN), Modem Status, and Received Signal Strength Indicator (RSSI). This does not apply to modems connected to the serial ports. SD CARD: The SD Card option allows the user to save and load controller information to a Micro Secure Digital memory card for later use. SAVE/LOAD CONFIGURATION: These options allow the user to save controller’s configuration for backup purposes, or to copy to another ACiC. SAVE TREND/EVENT DATA: These options allow the user to save the controller’s events and trend data for viewing using iCConnect. This option is pending future support. SAVE/LOAD FIRMWARE: These options allow the user to update the ACiC’s operating system using the SD card. This option is pending future support. ANALOG CHANNELS: This option allows the user to view the source of pressure and tank level values (Analog, FCU, or Disabled), as well as the settings for using the physical analog inputs as a digital alarm indicators. These settings can only be modified using the iCConnect utility. MODBUS SLAVE ID: This option sets the slave address of the ACiC when using the RS-232 or TTL port for Modbus communications to a host device or software. MODBUS ASCII: This option instructs the ACiC to use the Modbus ASCII protocol when set to YES. Set to NO for Modbus RTU. SYSTEM RESET: System Reset will return the controller to the default settings. 2913 Specialty Drive • P.O. Box 130158 • Tyler, TX 75713-0158 • Phone: 903-561-4851 • Fax: 903-561-6567
