“Set-Point ORP” (PWM) mode - Digital D1
This mode is valid for “Digital D1” output.
Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey
information over a communications channel or control the amount of power sent to a load.
This mode works over a settable (0 to 100 seconds) time to switch on or off selected output.
Time resolution is 5 seconds, 5 steps. During this time if reading value will move towards a set value (on or off) the PWM
will operate the output on timered basis. Reaching the set value the PWM will permanently leave on or off the output.
Parameters to set are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)
mV range: two pH value between PWM operates.
E.g: set rst value at 700 = 00% and second value at 680=60%.
For reading values ≥ 700 output will always be OFF.
For reading values ≤ 680 output will be ON for 60 seconds and OFF for 40 seconds.
If reading value is 690 mV the ouput will be ON with a 30% of total set time. (ON for 30 seconds, OFF for 70 seconds).
