These are the basic modes and controls of FXS P/D series:Proportional to external digital pulses:
Divider mode : step down (1: n), dividing factor 1999; The pump divides the external pulses received, thus dosing one injection, according the dividing factor selected.
Fixed mode 1:1: This mode of the pump is suitable for proportional controllers with pulses output for proportional control.
Multiplier mode : step up (1x n); The FXS P/D pump multiplies up to the max, the frequency for each pulse received.
Multiplier mode with memory : step up (1x nM), The dosing pump memorises the pulses receivedthuss conducting sequential injections
Parts per million: knowing the water meter pulse type, it allows to select the exact ppm dosing requirements.
Constant mode: selection of exact amount of stroke speed injections, mainly used to prime the pump.Connected to a Remote On/Off equipment, the pump starts and stops operations, according to the external contact.Flow detector Alarm Function: this function must be connected to FWT Flow Sensor (flow sensor availableon request). The pump goes in alarm, once the actual pump injections will not correspond to stroke frequency selected ( This feature is available only to PD+ DOSNIG PUMP SERIES).
Level control: level switch stops the pump when chemical level runs low allowing the pump to stay primed.Stroke length adjustment: The regulation of injection volume, combined with speed control allows top accuracy. This feature is available only to FX Dosing pump series.Note that FXS P /D series come with the Standard Accesories Kit, composed from1 - Injection valve;2 m - Discharge Hose PE semi-rigid (white);2 m - Suction Hose PVC flexible (transparent);1,5 m - Air Bleed Hose PVC flexible (transparent);1 - Foot Valve / Filter
