252.0 CONSTANT RATE Mode: Constant Rate/Pressure Filtration.SUMMARY: In this mode the selected pump rate (filtration feed rate) is maintained throughoutthe filtration process. The FilterTec Plus can then switch to a user selected constant filtrationpressure. The Pmaintain setting is chosen in the Alarm Enable: Hi-Pressure submenu tocause this to occur. First select the pump tube size (#13, 14, 16, 25, 17, 15, 24, or 35) (Note:the use of #18 is not recommended), and then select the pump rate in terms of ml/min, then setthe Hi-pressure Limit to the desired constant pressure. The FilterTec Plus feed rate can be re-calibrated by the utilizing the front panel star () key. (If you have changed the motor sub-assembly from the factory installed one, select the correct RPM of your new motor in SETUP:PUMP: Motor RPM submenu. (The choices are 8, 160 or 600-RPM.)Use “Up” and “Down” keys to make a selection, then press, “Select” to implement thatselection.Pump Tubing: Select sizes #13, 14, 16, 25, 17, 15, 24, or #35, using “Up” and “Down” keysfor choice of pump tubing size, then press “Select”. Based upon selection, the FilterTec Plusaccesses factory installed calibration curves, which relate the pump output in ml/min. to pumpmotor speed.Response F: Response Factor setting. The Pump Response Factor = 100 is the default value.Decreasing this Pump Response Factor will decrease the pumps responsiveness to pressurechanges.Clear Cumul: Resets (Clears) the following counters in the system: CV = Cumulative Volume;RT = Run Time; Q1 = Filtrate Weight.Pressure Zero: Allows you to zero the filter backpressure reading for all 3 SciPres Disposablepressure sensors, P1, P2 and P3. The FilterTec Plus must not be running when resettingpressure sensor output, and the sensor must be plugged in. Do not use the SPAN keyunless instructed to do so by Parker Customer Service. This is used to calibrate the pressuresensor output, and requires additional hardware.Alarm Enable: Allows you to select alarm options for several alarm conditions. Four options areavailable: 1. Off (Disable the Alarm); 2. Alarm Only (Enable an auditory alarm); 3. Pump Stop(Stop the pump and provide an auditory alarm); or 4. PMAINTAIN which switches the FilterTecPlus from Rate Control to Pressure Control at a user-defined limit and maintains that pressureby adjusting the system’s motor speed.NOTE: PMAINTAIN only exists as an option for the Hi-Pressure Alarm.Alarm Limits: Used to assign alarm limits for several alarm conditions:Cumulative Volume in milliliters;Low-Flow in ml/min;Hi-Temp in degrees Celsius;Run Time in Hours: Minutes;Lo-Pressure (monitor system leakage)in psi;Hi-Pressure (filter backpressure) in psi;Filtrate Weight in grams. (This alarm mustbe enabled in order to obtain and displaythe Filtrate Weight (Q1), and several valuescalculated from it.)
