Rated Pressure; Reserve Pressure; Unpair - PERDIX SHEARWATER Operating Instructions Manual

Operating Instructions

Rated Pressure

Enter the rated pressure of the tank on which the transmitter
is installed�
The valid range is 1000 to 4350 PSI (69 to 300 bar)�
The only use of this setting is to scale the full-scale range of
the gas pressure bar graph
Zero
Pressure
Rated pressure is only used to scale the pressure bar
FIGURE 14

Reserve Pressure

Enter the reserve pressure
The valid range is 400 to 2000 PSI (28 to 137 bar)�
The reserve pressure setting is used for:
1) Low pressure warnings
2) Gas Time Remaining (GTR) calculations
A yellow "Reserve Pressure" warning will be generated
when the tank pressure falls below this setting�
A red "Critical Pressure" warning will be generated when
the tank pressure falls below the larger of 300 PSI (21 Bar)
or half the reserve pressure�
For example, if reserve pressure is set to 700 PSI, the critical
warning will occur at 350 PSI (700/2)� If the reserve pressure
is set to 400 PSI, the critical warning will occur at 300 PSI�
