To disable Extraction control slowly raise the LP valve limiter until the Extr/Adm PID loses control of its respective process, then continue to increase the LP valve limiter to its maximum (open) position. Automatic Enable / Disable After receiving an enable command, the 505E will automatically lower the LP valve limiter at the “LP valve limiter rate” setting. Once the Extr/Adm PID takes control of its process, the LP valve limiter will continue lowering to its minimum (closed) position at five times the “LP Valve Limiter Rate” setting.
The LP valve limiter may be stopped at any time during the automatic enabling routine by momentarily issuing a LP limiter raise or lower command (or by entering a valid setpoint). Stopping the automatic enabling routine halts the LP valve limiter. The Extr/Adm PID’s output will still continue to be enabled. This allows an operator to manually adjust the LP valve limiter as desired. By reissuing an enable command, the enable routine will continue lowering the LP valve limiter. If a contact is programmed for this function, it will have to be opened and re-closed to re-issue an enable command. The 505E only accepts an Extraction enable command if all related permissives are met (see above list). An enable/disable command may be given from the 505E keypad, a contact input, or through Modbus. The last command given from any of these three sources dictates the state of the Extraction control. When a contact input is programmed to function as an enable/disable command, a closed state represents an enable command and an open state represents a disable command. This contact can either be open or closed when a 505E trip condition is cleared. If the contact is open it must be closed to issue an enable command. If the contact is closed, it must be opened and re-closed to issue an enable command. To enable and disable Extraction control from the 505E’s keypad, press the Ext/Adm key to view the Extr/Adm control screen, then press the Scroll Down key once to display the Extraction Status Screen.
At this point press the “Yes” key to enable the function, or press the “No” key to disable the function. Upon receiving a disable command the 505E will instantly step the LP valve limiter to the LP valve’s present position, then raise the LP limiter to its maximum (open) position at the “LP valve limiter rate” setting. At some point, depending on system conditions the Extr/Adm PID will lose control of its process. The LP valve limiter may be stopped at any time during the automatic disabling routine by momentarily issuing a LP limiter raise or lower command. Upon stopping the automatic disabling routine an operator can continue the disabling routine manually as desired or re- issue a disable command. By re-issuing a disable command the disable routine will continue raising the LP valve limiter to its maximum (open) position. With automatic Extraction enabling programmed, an operator can also enable and disable Extraction control manually if desired.
