Constant mode: adjustment of injection frequency stroke per minute; stroke per hour; stroke per day. Connected to a Remote On/Off equipment, the pump will start and stop operations according to the external contact. Proportional to external digital pulses:
Divider mode : step down (1: n), dividing factor 1999; it divides external pulses received then effects one injection according the dividing factor selected.
- fixed mode 1:1: suitable for proportional controllers with pulses output for proportional control.
- multiplier mode : step up (1x n); it multiplies up to pump max frequency for each pulse received
- multiplier mode with memory : step up (1x nM), it memorised pulses then effect sequential injections
- PPM (parts per million): knowing the water meter pulse type, it allows to select the exact ppm dosing requirements
Flow detector Alarm: this function must be connected to the flow detector model Flow Sensor. The pump will go in alarm once the actual pump injections will not correspond to stroke frequency selected. Alarms via buzzer remote relay. Clock: time and date setting Timer: digital timer, weekly and daily programming; ideal for biocide dosing for cooling towers Language: language programming selection Level control: level switch stops the pump when liquid level runs low allowing pump to stay primed. Level alarm output contact: output contact N.O./N.C. to drive external equipments 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 CS/D series come with the Standard Accesories Kit, composed from 1 - 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
