To View Real Time Displays
Choose *Dsp in the main menu, figure 113.
Strokes signaled are the number of pump strokes signaled by
the N-300 controller are shown in this display, figure 114.
To reset strokes signaled, press the *Rst key and
follow instructions, figures 115-115a.
Odorant Injected, figure 116, is the cumulative total of
odorant injected in lbs. (kg) is shown in this display.
To reset lbs. (kg) injected, figures 117, press the *Rst
key and follow instructions, figures 117-117a.
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-300 with volume data supplied
by the Verometer, figure 118.
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,
refer to the Program-
ming Sections 5 & 6, beginning on pages 25 & 33.
Pump Alarms
There are three conditions that will result in a pump alarm
indication.
• Over Pumping, figure 119, the calculated pump dis-
placement exceeds the set pump displacement by 30%.
• Under Pumping, figure 120, the calculated pump displace-
ment is less than the set pump displacement by 30%.
• Pump Failure, figure 121, the calculated pump
displacement is less than the set pump displace-
ment 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.
