FS10 Series14 Fluid Components International LLCFS10 Field Quick Setup ProcedureQuick Setup Mode *This feature permits field setting the critical zero and span parameters of the FS10A with a single push of the button and throttling the process flowover the desired range to capture the low and high ends. All defaults applicable to a low flow indication/alarm application apply along with atrip-point default setting at 30% of span.To activate the Quick Setup Mode (QSM), simply press and hold for at least 10 seconds:“ – “ button, for process fluids that are gases or very low flow liquid hydrocarbons“ + “ button, for process fluids that are liquids or high velocity gases (+50% sensor excitation).The first three and last three LEDs will alternately flash to acknowledge entry into the Quick Setup Mode. The FS10A is now cued to remember thelowest and highest flow signal it sees while in this mode. Pressing either button momentarily exits into the normal operating mode and saves thedetected limits as the zero and span. LED’s 1 and 10 and corresponding trip point LED will alternately flash (3 sec), indicating zero and span havebeen properly set.A minimum span setting of 0.05% is required to save new parameters. If minimum span is not reached during QSM, the first two, middle two andlast two LEDs will flash; indicating an error (3 sec) and resume last operation without saving new parameters.Note: Apply any desired hysteresis, time delay, failsafe, etc. changes to the standard default settings after the zero max flow usingthe Quick Setup Mode. Entering the QSM resets these parameters to the standard low flow alrm default settings as definedfor bank 1(-button) or bank 3(+button).Tip: To use the QSM in the field after changing the factory low flow alarm default settings (i.e. failsafe, hysteresis, time delays,etc.); setup as desired and save change sto bank 7 (under Calibration Bank Setup window in the PC interface program). thengo to the Quick Setup Mode window and change the default “Bank Selection” for either the - button or + button to bank 7.Now when the newly assigned button is used to learn the zero, span and set the trip point, it will use the saved parametersstored in bank 7.RecommendationsGas applicationsThe high flow limit or span setting is normally the most difficult to stabilize in a gas application, therefore simulating the desired high flow rate atnormal process conditions and allowing it to stabilize before entering into the QSM is recommended. Using in-line valves or other throttling means,establish the desired full scale flow rate and allow system to stabilize. Now enter into the QSM (FS10 immediately captures this high flow signal)and then slowly throttle the flow down until the zero flow setting is reached (i.e. valve closed, no flow). Allow to stabilize, then momentarily presseither button to save parameters and return to normal operating mode with the new scaled operating range established.Liquid applicationsTo optimize the performance of the FS10A in liquids, it is critical to establish a stable zero setting under a packed line (full) condition. It isrecommended the FS10A be operating and allowed to come to equilibrium with a downstream valve closed and the line completely filled with theprocess fluid and no flow. At this point, enter into the QSM (FS10 immediately captures this low flow signal), and then slowly open the downstreamvalve to allow flow up to the maximum span desired. Momentarily press either button to save parameters and return to normal operating mode withthe new scaled operating range established.In some cases the high liquid flow signal will saturate before reaching the high flow that is simulated, but the FS10A will save the highest value it iscapable of sensing in that application and use it as the high end limit.Trip pointBy factory default, the trip-point is set to 30% of the established span when using the Quick Setup Mode. This may be changed in the field usingthe standard button commands (refer to Functions 1 and 2 under Normal set-up and operation using the button interface in the operating manual).Alternatively, the QSM factory trip-point default of 30% of span may be changed in the field using the PC interface program before entering into theQSM. Selecting the factory setup option at order will also permit designating an alternative customer desired default value at the factory. Note, thisvalue is always a % of the established span and alters any previous trip point that may have been attained on a previous setup.Note: The 4-20mA output and relay trip will continue to operate at the previously set range while in the Quick Setup Mode |
