What to do if there is an option valve error in SAB Water Filtration System?
- J
  Jeffrey PaceAug 27, 2025
  If you're experiencing an option valve error with your SAB Water Filtration System, here are a few things to check: * Flushing valve does not open or close: Check the function of the flushing valve and the compressed air supply. * Proximity switch defective or wrongly wired: Check the function of the end position switch. * Compressed air hoses exchanged: Check the compressed air hoses for the right connection. * Solenoid valve defective: Check the function of magnetic valves SV1, SV2 and replace if necessary. * Sound absorber in the solenoid valve is blocked: Dismount the sound absorber and clean it; if necessary, replace it.

Why is there continuous flushing in my SAB Water Filtration System?
- B
  Brittany GonzalesNov 4, 2025
  Continuous flushing in your SAB Water Filtration System can occur due to several reasons: * Air in the differential pressure switch: Vent the differential pressure switch using the vent screws. * A defective differential pressure switch: Check the function of the differential pressure switch. * A defective optional differential pressure transmitter: Check the function of the differential pressure transmitter. Read the active actual value in the parameter menu system/pressure threshold and compensate with the pressure threshold. * Wrongly connected contacts: Check the wiring. * Disconnected contacts in the control system/DDS: Check the wiring for a correct fit. * A soiled DDS line: Disassemble and clean the DDS lines. * A mislaid back flushing line: Ensure the back flushing l...

What to do if my SAB Water Filtration System has a stroke error?
- C
  Cathy HaasNov 11, 2025
  A stroke error in your SAB Water Filtration System could stem from several factors: * Throttle valves at the cylinder are closed: Open the throttle valves until the running time aligns with the manual's specifications. * The stroke time isn't correctly set in the control system (control time): Set time T3 in the control system according to the manual. * The stroke time isn't correctly set in the control system (running time too long): Open the throttle valves until the running time aligns with the manual's specifications. * The system pressure of compressed air is too low, or the flow rate is too high: Ensure the internal compressed air pressure is at 87 psi (6 kg/cm2g) / special 50.7-116 psi (3.5-8 kg/cm2g). Low air pressure can affect the cylinder's running time. * The orifice...

Why is my SAB Water Filtration System not cleaning well?
- T
  Tommy WilsonNov 19, 2025
  If your SAB Water Filtration System isn't cleaning effectively, consider these potential causes: * The cylinder-piston current time is not set correctly (current time undervalued): Check the current time length and set correctly if necessary. * Back flushing line mislaid: The back flushing line should be laid pressure-free. * Failure of control system: Possibly the current supply failed, whereby the cleaning did not take place in the regular interval. Remove filter insert and clean it with high pressure cleaner. * Differential pressure switch defective: See "continuous flushing" in this table. * Actual operating parameters (characteristic line of pump, flow rate, pressure etc.) have changed: Let check the geometry of flushing disc/orifice by the manufacturer, let change if neces...
