automation process will operate the valves to balance levels across all tanks.
LPG Empty Threshold
When a tank level reaches this threshold, the automation process will open the valve
for that tank.
LPG Temperature
Source
Source for temperature reading.
Open all Valves on
Temperature reading threshold point that we follow to open all valves.
LPG Valve Control Settings
Id
ID number of the tank valve.
Description
User-definable description of the tank valve. Same description as in the Controls
Page.

Details
Record Freq
The frequency with which the NetGuardian will record the analog reading.
Deadband
The additional qualifying value the NetGuardian requires above/below your alarm
thresholds in order to set an alarm.
Units The unit(s) of measurement reported by a connected analog input.
Low ref and High Ref The low and high values for scaling voltage to your display units.
MjU (Major Under)
MnU (Minor Under)
MnO (Minor Over)
MjO (Major Over)
Threshold settings that, when crossed, will prompt the NetGuardian to set an alarm.
Recorded values less than an under value or greater than an over value will cause
alarms.
Post On
Select the threshold alarms to post. All thresholds, Major Only, Minor Only, Major Over
Only, Major Under Only.
Enable Checking this box enables Push-to-Talk feature for this analog.
Discrete Input Assign the alarm point associated with this analog.
Qual. Time (ms)
Length of time, in milliseconds, that an alarm point must be set before before an analog
can post.
Analog Gauge Type
Select the type of analog gauge represented in the Monitor>User Analogs>Gauge
View menu.
When the LPG Automation Process is enabled, the NetGuardian LPG blocks user control of the tank
valves. The automation process will analyze the tank level readings and compare them against the
Action Threshold to control the tank valves to maintain that all tank levels are decreasing at the same
rate. When any tank level drops below the Empty Threshold, the automation process will leave the tank
valve open. If a temperature source is configured, the automation process will open all tank valves
once the configured threshold point (MJO, MNO, MNU, or MJU) has been set.
If the automation is disabled, the user retains control of the tank valves.
Alarms 10.8
Discrete alarms are configured from the Provisioning > Alarms menu. Descriptions for the alarm points, polarity
(normal or reversed) and notification type(s) are defined from this menu. You also have the option to use Basic or
Advanced configuration methods, explained in this section.
