Section 8: Working with the N-300 System Displays
To View Real Time Displays
Choose
*Dsp
in the main menu,
figure 117
.
Strokes signaled
are
the number of pump strokes
signaled by the N-300G controller are shown in this
display,
figure 118
.
To reset strokes signaled,
press the
*Rst
key and
follow instructions,
figures 119.
Odorant Injected,
figure 120,
is the cumulative total
of odorant injected in lbs.
(kg)
is shown in this display.
To reset lbs.
(kg)
injected,
figures 121,
press the
*Rst
key and follow instructions.
Note:
Pounds – lbs. (kg) injected will increment only
when a valid pump displacement has been calculated.
Pounds – lbs. (kg) injected will not increment during fill
valve alarm condition.
Pump Displacement
This display illustrates the last value, in cc / stroke,
calculated by the N-300G with volume data supplied
by the Verometer,
figure 122
.
Note:
an asterisk “
*
” following the value illustrated
in the display designates that a value has not been
calculated at present, and the previously set or
programmed pump displacement will be displayed,
efer to the Programming Sections 5 & 6, beginning on
Pump Alarms
There are three conditions that will result in a pump
alarm indication.
•
Over Pumping,
figure 123,
the calculated pump
displacement exceeds the set pump displacement
by 30%.
•
Under Pumping,
figure 124,
the calculated pump
displacement is less than the set pump displace-
ment by 30%.
•
Pump Failure,
figure 125,
the calculated pump dis-
placement is less than the set pump displacement
by 75%. For example, low displacement due to an
empty meter, the pump cannot inject odorant when
required if the meter which supplies the odorant to
the pump is empty.
