The analyser is complete with:
4 programmable relay outputs: maximum value one, maximum value two (or minimum value and maximum value), command for a cooler, for a washing valve, pump, error, missing indicator, remote signal.
1 output 0 (4) -20mA: analysis result (linear hardness) and operation
2 programmable digital inputs: water meter, turbine water meter (Hall), flow meter, external start or stop commands.
MODBUS RTU connection.
CANBUS connection (optional).
SD card connection: data/results/error saving and transfer with date and time, software update.
A bad analysis can be repeated (just exceeded the maximum value, without giving an alarm signal).
Extensive function control program, relay drive, Leeds drive, accessory control.
Steps of an analysis cycle: opening an inlet solenoid valve – washing the measuring chamber for a settable time – checking the transparency of the water (zero point) – dosing the indicator by a peristaltic pump – result of the measured iron (by display) – final washing of the measuring chamber – the equipment stops waiting for the next analysis (timed, volumetric, manual or external signal start).
