YPP6830 Pulse Input Rate/Totalizer Instruction Manual
61
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 K-factor). A pulse will be generated for every total accumulation amount
equal to the count.
If the maximum output frequency would be exceeded, the meter will display 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 would be exceeded, the meter will display 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 selec-
tion.
Test Output (
test
)
The test output setting programs the output to generate pulses at a programmed
constant frequency. Set the frequency decimal point location in the
DECPT
menu, and
then enter the desired output frequency in Hz in the
PULSE
menu.
