Modular pulses, also known as PWM “pulse width modulation”, support a proportional mode on each ON
-OFF
setpoint, activating the corresponding pulses on the output relays based on the measured value and always
relating to the previous selected settings.
The default activation point is
0.050 ppm (2 Cl ppm); 0.50 ppm (range 20 Cl ppm, 0-10ppm CLC Cell).
For more accurate settings of the
“Modular pulses”
PWM, select the
“Expert”
menu in the initial settings.

FUNCTION ONLY AVAILABLE WITH SETPOINT 1
The MIN and MAX Alarm function selects the alarm levels beyond which the alarm relay is triggered on.
ONLY WHEN USING METERING PUMPS
The priming function blocks the setpoint value to allow the metering pump to
remain primed, the outputs are not active.

The chlorine parameter has 3 ranges suitable for ion-selective membrane sensors (one of which for the Total chlorine) and a range
for open type amperometric cells .
NOTE
During calibration, the - (minus) sign might be displayed, which disappears or is removed by correct settings! The value in the lower part of
the display shows the sensor signal in mV thus indicating the sensor’s efficiency. It is advisable to perform constant checks
and periodic
recalibration of the sensor, via DPD1.
For the calibration
of ion-selective membrane
sensors always refer to the probe’s manual.
In BASIC MENU mode calibration is performed with one point only, the DPD one.
Select the value of the required sample solution and check with the DPD1 test kit for free chlorine, or with portable instrument, measure the
chlorine concentration in ppm (residual or total) in water, wait for the measurement to stabilise, p
ress and hold ▲▼ until showing the value
obtained with the DPD method then confirm with O O K / M E N U U
