Section 8: Working with the N-300 System Displays
To View Real-Time Displays,
Continued
Expansion Tank
This display illustrates the expansion tank pressure,
figure 129
.
Odorant Inlet
Displays the pressure of the bulk odorant storage
tank via the pressure transmitter located at the fill rate
control valve,
figure 130
.
Battery Voltage
The battery voltage is shown in this display,
figures
131
.
•
Battery Alarm,
a low battery is when the voltage is
less then 11.5 VDC.
Flow Input
This display,
figure 132,
illustrates the flow rate as a
percentage of the maximum gas flow. The following
represent the alarms that are associated with this area
of the N-300G controller.
Flow Input Alarms
•
Loss of Signal,
figure 133,
the flow signal is less
than .5 VDC, for the analog input only.
•
Over Flow,
figure 134,
the flow input has exceeded
125% of the maximum gas flow.
Flow Input Indicators, non-alarm
•
Low Flow,
figure 135,
the flow input has fallen be-
low the low flow shut off set point
Programming for Proportional-to-Flow page 26
•
Over Flow
,
figure 136,
the flow input has exceeded
110% of the maximum gas flow, but is still less than
125% of maximum gas flow.
•
No Flow,
figure 137,
is presently indicated by the
flow signal.
•
Low Flo Shtoff,
figure 138,
the flow signal indicates
a flow rate less than programmed for odorization.
