MENU 6.OUTPUT
(POS. 6.1-6.2-6.3-6.4) Function corresponding to on/off output 1-2-3-4 [OUT1=XXXXXX]
Choice of the function corresponding to digital Output 1. The functions are listed in the table to the
next page
The output 3-4 are optional and the output 4 it’ the only output, which can reach a 12.5
KHz frequency.
(POS. 6.5)duty cycle value for pulses/frequency output [OUT.1=XXXXXX]
The duty cycle function define the time ratio between ON and OFF state when frequency output are
used: 50% it mean that the ON phase will be the same of OFF phase, 60% it mean that the phase
ON will be 60 % and phase OFF will be 40% of the total cycle time.
When pulses outputs are used , the duty cycle define the OFF phase because the ON phase it’s
already set with the function "PULSE DURATION"( see menu “SCALE” ) . In this case if is setting for
example the duty cycle at 50% and the pulse duration to 50ms, the OFF phase will be the same of
ON phase. The formula for calculate the minimum time of the OFF phase and the time of total cycle
is the following:
T. total cycle= 100 x (pulse duration in ms)/ (duty cycle)
T. OFF phase = T. total cycle - pulse duration
N.B.: If the value of the function is set to 0 the issue of the pulses happens in synchronous mode with
the flow rate therefore when is uses the function in frequency DOESN'T set the duty cycle to 0.
