Direct
mode: the output is active when the measured value is
lower
than
the one selected in the setpoint, the metering pump injects Chlorine.
Reverse
mode: the output is active also the measured value is
higher
than
the one selected in the setpoint, the metering pump injects a Chlorine
reducing agent.
The unit has an
ON-OFF
mode which switches on or off (if the reverse mode
is ON) The output relays of Constant / ON-OFF metering pumps or other
ON-OFF equipment.

�
“MIN ALARM” (ONLY SET POINT1)
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, 20 Cl ppm (Total), 0-10ppm
CLC Cell).
For more accurate settings of the
“Modular pulses”
PWM, select the
“Expert”
menu in the initial settings.

GOING BACK TO THE SETPOINT PROGRAMMING STEPS FROM THE
“ON-OFF”
MODE OR
“PROPORTIONAL”
MODE
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.
