YPP6830 Explosion-Proof Pulse Input Rate/Totalizer
Output 1 and 2 Setup (OUT 1, OUT 2)
The function of open collector output 1 and 2 is
configured using the Off, Pulse, Alarm, Timer, and
Total Reset menus detailed below.
Pulse Output (PUlse)
Pulse outputs may be assigned to rate, total, grand
total, retransmit, quadrature, or test.
Rate Pulse Output (rate)
A rate based pulse output is a factor of the input
frequency and the Count (InvK-Factor). The rate
display is a factor of the input pulses, time base, and
the input
K-Factor. The rate of output pulses over one time
base (seconds, minutes, hours, days) is defined
below in terms of input pulses, the input K-Factor, and
the Count (InvK-Factor) parameters.
Example:
Input = 1000 pulses/sec
K-Factor = 10 pulses/gallon
Rate = 100 gallons/sec
Count (InvK-Factor) = 100 gallons/pulse
(Inverse K-Factor = Volume units/pulse)
Pulse Output = 1 pulse/sec
Total & Grand Total Pulse Output (Total, Grtot)
A total and grand total based pulse output is a factor
of the associated total and count (output InvK-Factor).
A pulse will be generated for every total accumulation
amount equal to the count.
If the maximum output frequency is exceeded, the
meter displays the message pUlse OVERRNG
alternating on the display.
Retransmit Output (retr)
The retransmitting pulse output will send an output
pulse for every input pulse, essentially duplicating the
input signal. The output will generate a pulse at the
falling edge of every input pulse.
No additional programming is required for a
retransmitting pulse output.
If the maximum output frequency is exceeded, the
meter displays the message pUlse OVERRNG
alternating on the display.
Quadrature Output (quad)
The pulse output set to quadrature will duplicate the
other open collector output, but lag by ¼ duty cycle
(90 degrees out of phase). For example, Out 1 will
follow Out 2, if Out 1 is set to quad. Only one output
should be set to quad. If both outputs are set to quad,
both outputs will be disabled. The other output should
be programmed as desired for the quadrature output
function, and must be a pulse (PUlse) output
selection.
