SETPOINT 1 PH AND SETPOINT 1 RX > BASIC MENU
SETPOINT1 PH
SETPOINT1 RX
The two programming stages are set out below: when Measurement Type
pH is selected, refer to the left column; when selecting RX refer to the right
column.
The setpoint activates the output relays for the metering pumps or for other
devices until the setpoint is reached.
Setpoint 1 is set (default) in ACID
mode, the output is active when the
measured value is higher than the
selected setpoint, the connected
pump meters out an acid product.
Setpoint 1 is set (default) for
operations in DIRECT mode: if the
measured value is lower than the
setpoint, the connected pump
meters out chlorine (Oxidising
product).
The unit has an ON-OFF mode which switches on or off (if the reverse mode
is ON) the output relays of metering pumps or other equipment.
BY SELECTING “
ON-OFF”
THE NEXT STEP IS
“MIN ALARM” (SET POINT1 ONLY)
Modular pulses, also known as PWM “pulse width modulation”, support a
proportional mode on each ON-OFF setpoint, activating the corresponding
pulses on the relays based on the measured value.
Default activation point 1.50 pH
Default activation point 150 mV
For more accurate settings of the “Modular pulses” PWM, select the “Expert” menu in the initial settings.
