4-20 Ma Transmitter Output; Open Collector Output; Serial Communications - YOKOGAWA YPP6830-AP0-0 Instruction Manual

YPP6830 Explosion-Proof Pulse Input Rate/Totalizer
Total Overflow The total can display up to
9,999,999,999,999. Up to 9,999,999
And Rollover
can be displayed on the lower display
normally. An overflow display will
toggle between the first six digits and
last seven digits (999999 <> 9999999)
for a 13-digit total. The total will rollover
beyond thirteen digits. The T indicator
on the display will flash to indicate total
overflow, and the six most significant
digits (first six numbers of the total) are
indicated with the flashing overflow
symbol .
Grand Total The grand total can display up to
9,999,999,999,999. Up to 9,999,999
Overflow And
can be displayed on the lower display
Rollover
normally. An overflow display will
toggle between the first six digits and
last seven digits (999999 <> 9999999)
for a 13-digit total. The grand total will
rollover beyond thirteen digits. The GT
indicator on the display will flash to
indicate grand total overflow, and the
six most significant digits (first six
numbers of the grand total) are
indicated with the flashing overflow
symbol .
External Total
External total reset connections are
Reset made between RST and COM.

Open Collector Output

Output Two open collector pulse outputs Out 1
Assignment and Out 2.
Individually programmable for rate,
total, or grand total alarms; rate, total,
or grand total pulse outputs; or
retransmitting of pulse inputs; constant
timed pulse output; quadrature outputs
(requires Out 1 and Out 2); or off.
Rating Isolated open collector, sinking NPN
30 VDC @ 150 mA max.
Alarm Output Assign to rate for high or low alarm trip
point.
Assign to total or grand total for total or
grand total alarms.
Alarm Deadband 0-100% FS, user selectable
Alarm Front panel ENTER button resets
Acknowledge output and screen indication.
Pulse Output The InvK-Factor (couNT) is
(Count) programmable from 0.000001 to
9999999. Total and grand total pulses
InvK-Factor = are generated for every total or grand
Volume/Pulse total increment selected. (e.g. InvK-
Factor = 100 gal/p will generate one
pulse every time the total is
incremented by 100 gallons).
Rate pulses are generated as a scaled
output of the input frequency with one
output pulse per InvK-Factor (count).
Rate retransmission outputs one pulse
per one input pulse, up to the
maximum output speed.
Pulse Output Unless otherwise stated, pulses are
Pulse Width 50% duty cycle for required frequency.
A pulse rate retransmit output will
generate 100 to 130 μs pulses at the
falling edge of every input pulse.
Pulse Output 5 kHz, pulse width at 50% duty cycle. If
Maximum the programming of the outputs would
Frequency exceed 5 kHz, the meter will display
pUlse OVERRNG
Quadrature Output set to quadrature will lag the
Output other pulse output by 90°
(1/4 duty cycle) at output frequency.
Minimum 1 Hz
Timer Output Programmable On and Off time,
repeating cycle. Minimum On time:
0.01 second, maximum On time:
10,000 seconds. Minimum Off time
(Delay Period): 0.1 second, maximum
Off time (Delay Period): 100,000
seconds. Ýelay Period: Countdown
time delay (Off) after start is pressed.
Ðn Time: Time the open collector stays
on.
