SETUP
The instrument shows:
1a) ->OFF
1.00Cl
Pressing twice “RIGHT” key the display will show:
1b) ->ON
0.00Cl
“1a)” and “1b)” are working range values. Every range is set by a value that operates relay output. Using default values, the
setpoint 1 will drive a pump that will increase the chlorine value. The pump will switch on for Cl values minor than 1.00Cl
and switch off when reaches 0.00Cl: this is the ON/OFF working mode. The difference between the two Cl (1.00 and
0.00) is called HYSTERESIS.
To avoid damaging the relay do not set Hysteresis under 0.20Cl.
PROPORTIONAL mode.The output relay is modulated (ON/OFF) depending on Cl values set in 1a) and 1b). Ex.: Proportional
mode between 1.00Cl (0%) and 0.50Cl (100%). In this way the relay will be on for values between 0.00Cl and 0.50Cl, it will
be on for values higher than 1.00Cl. For values between 1.00Cl and 0.50Cl the relay will be on or off depending on calculated
percentage.
The calculation is based on a 100 seconds time. If Cl reaches 0.60Cl the relay will be on for 80 seconds and off for 20 seconds.
To set the PROPORTIONAL functioning mode substitute percentual value to “ON” and “OFF”.
It is not possible to enter mixed values (ex.: 100% for SP1 and ON for SP2). In this case it will not possible
save them.
In proportional mode the instrument doesn’t show % values for setpoints status but only if they are on or off.
It is possible modify setpoint status (on,off, %) and setpoint values with RIGHT key on the function to modify and using “UP”
and “DOWN” key to change the value. Enter the value and save by pressing “E” to save.
Repeat sequence for setpoint 2 (OUT2).
Press “E” key to exit from setpoint setting. The display will show “SetPoint Saved” and it return to the
previous menu.
Out mA
This function allows to program the current output for driving a metering pump or a chart recorder.It is possible to program in
0÷20mA mode or 4÷20mA mode in the working range between 0 and 9.99ppm.The current output and the working range may
be modified. Ex.: it is possible to set 4mA at 9.99ppm and 20mA at 0ppm. In this case, if you connect a metering pump it will
dose at the maximum flow at 0ppm.The pump will reduce the flow when Cl decrease and it will stop at 9.99ppm. If you connect
a chart recorder, a graphic curve will be printed. Set minimum current value to 0ppm and maximum current value to 9.99ppm.
Use “UP” and “DOWN” keys to change these settings. Press “RIGHT” key to scroll through the options. Press “E” to confirm.
