mA The pump doses in proportional way to the power signal
Operating range:
0 – 20 mA pulses per minute
0-120 pump pulses per minute
Minimum and maximum cutoff points are adjustable: Stop/Continue dosing
PPM The pump can dose directly in PPM. User can set the following parameters:
Water meter liter/contacts 0.1, 0.25, 0.5, 1, 2.5, 5, 10, 25, 50, 100, 250, 500, 1000. cc/injec-
tion 0.00 - 20.00 Concentration of solution (%) - PPM 0.1 – 20.000
ACCESSORY FUNCTIONS:
FLOW ALARM A flow sensor (optional) checks the pump flow and activates an alarm should the flow stop
Reference injections 0 - 100 - Max injection difference 0 - 100
RELAY SERVICE Enabled through a flow alarm
Characteristic: 1 pole - 250V a.c. 5A (resistive load)
BUZZER Audible alarm for missed pump pulses can be Enabled / Disabled
CLOCK Date and time
day/month/year
hour/minutes
Clock holds its settings in the case of power failure of up to 24 hours. Prior to initial use,
pump should be powered for 4-5 Hrs to precharge internal battery
