1.2 Product Overview
The LineGuard Electronic Linebreak Detection System is a self-contained
pipeline monitoring and line break detection device. The device is
intended to be installed at a pipeline valve site and is designated to provide
data acquisition and supervisory control (both locally and remotely) of a
single valve actuator.
The LineGuard product consists of standard FloBoss 107 Flow Manager
hardware and firmware while a user program provides the LineGuard
functionality. The program is responsible for pressure monitoring, data
logging and valve control. Custom user-defined displays are available for
configuring and monitoring the operation of the program.
LineGuard 2300 Program User Manual
2 Revised March-21
1.2.1 Basic Program Operation
This section briefly describes the operation of the LineGuard user program,
which monitors pipeline pressure, calculates the Rate of Pressure Drop
(RoD), maintains minor and major logs, and performs valve control.
Pipeline Pressure
Monitoring
The static pipeline pressure is sampled every 5 seconds and stored as Live
Pressure. This value is averaged over a configurable period called the
Average Sample Period and is stored as Average Pressure. The Average
Sample Period is user-configurable from 5 seconds to 60 seconds in 5
second intervals. The default Average Sample Period is 60 seconds (or 12
samples). The average pressure is averaged over a moving time window
and the time window is defined by the average sample period. The average
pressure is updated every 5 seconds. The average pressure is used to detect
major and minor line-break conditions. The average pressure is archived in
both major and minor data logs.
Rate of Drop (RoD)
Pressure Calculation
The LineGuard device reacts to a drop in pipeline pressure. The current
Rate of Pressure Drop (RoD) is calculated as the change in average
pressure over the last minute and is available every sample cycle (5
seconds) in units of pressure/minutes. The current RoD is rolled over to an
average RoD based on the average sample period. The average sample
period for RoD calculations is equal to the sample period used in
calculating average pressure. The average RoD is used to detect major and
minor line-break conditions. The average RoD is archived in both major
and minor data logs.
Data Logging
The LineGuard program maintains four data logs, major data logs, event
logs, and alarm logs.
Minor Data Logs
A Minor Log is initiated when a minor alarm is enabled and becomes
active. Alarm conditions include when the average pressure is less than the
minor low pressure setpoint, average pressure greater than the minor high
setpoint, and average RoD greater than the minor RoD setpoint. Each
minor log setpoint and alarm is user configurable.
A complete minor log consists of a beginning time stamp (MM/DD/YY
HH:MM:SS), 60 average pressure values and 60 average RoD values.
Values are stored in the log at a user configurable Minor Log Period. Valid
log periods for a minor log include 30 seconds, 1 minute, 2 minutes, 3
minutes, 4 minutes, and 5 minutes. At each log period the current average
pressure and average RoD is written to the minor log.
A minor log archives 60 (complete log) values for average pressure and
average RoD values regardless of whether the initiating alarm condition
persists. A log is archived to memory once the log is complete. Another
minor log is initiated if the minor log alarm condition remains active.
A total of 100 minor logs can be stored in the unit. Minor logs are circular
logs with the earliest log overwritten with the newest log once all 100 logs
are full. Minor log data archival will also stop 50 logs (60 values each)
after a major log alarm condition becomes active and will not resume until
LineGuard 2300 Program User Manual
Revised March-21 3
after the user has manually cleared the major log alarm state.
Major Data Logs
A Major Log is initiated when a major alarm becomes active, the alarm is
enabled, and the event duration period has been satisfied. Alarm conditions
include Average Pressure less than the Major Low SetPoint, Average
Pressure greater than Major High SetPoint, and Average RoD greater than
Major RoD SetPoint. Major Log SetPoints, alarms, and event durations are
user configurable.
A complete Major Log consists of a time stamp (MM/DD/YY
HH:MM:SS), 30 average pressure values, and 30 average RoD values prior
to the major alarm becoming active and 30 average pressure values and 30
average RoD values after the major alarm became active. The time stamp
indicates the actual time of the line break.
Only one major log is saved in the LineGuard unit. A major log will be
retained and not overwritten until you manually clear the major alarm state
by pressing Clear Logs on the LineGuard Status screen. Values are stored
in the log at a user configurable major log period. Valid log periods for a
major log include 5 seconds, 10 seconds, 15 seconds, and 30 seconds. The
current average pressure and average RoD is written to the major log at
each log period.
Event Logs
The program adds an entry to the Event log when changes in setpoints or
parameters occur that affect program operation. Changes can include
remote and local commands to change valve position, change setpoints,
and change in parameters that affect any aspect of the LineGuard
operation. The standard FloBoss firmware performs event logging. Event
data may be used to establish a history of LineGuard status and pipeline
valve activity. The circular event log maintains a maximum of 240 records
and overwrites old data as new events occur.
Alarm Logs
Alarm Logs are triggered by exceeding operating limits and setpoints. The
alarm log function is performed by the standard FloBoss firmware. The
alarm log collects, and stores data not directly related to operator change
requests. Alarm entries include battery low voltage condition and any other
input point high and low condition. The alarm log can store up to 240
alarms and overwrites old entries as new alarms are encountered.
An alarm entry is also created when a minor or major alarm becomes
active, a Minor or Major Alarm becomes inactive, and when automatic
valve closure is initiated, and a transmitter fail condition becomes active or
clears. The following user text type alarm is created by the calculation
program.

Trans OK
Indicates the value and time at which the pressure value
reported from the transmitter are within alarm limits.
Shutdown Control
The LineGuard program automatically closes the valve when a major line
break is detected.
Line Break Detection
The Average Pressure and Average RoD are used to detect line-break
conditions every sample cycle (5 seconds). Valve closure is activated when
the four following conditions are met: a major log alarm becomes active, it
remains active for the configured Event Duration, auto-closure is enabled
for the event, and the Close Output field is defined. The major log will
continue to record data until it becomes full. The event duration can be
configured from 0 seconds to 1800 seconds (30 minutes).
If the average pressure or average RoD returns to an allowable level during
the event duration period, then valve closure is not initiated and normal
pressure monitoring resumes.
Once a line-break situation has been detected, valve closure is completed, a
major log is filled, and then all log recording and valve control stops. The
user must select Clear Logs on the LineGuard Status screen before normal
pressure monitoring, logging, and control is resumed. If the Open Output
field is defined, the user can open the valve by selecting Force Open on
the LineGuard Valve Control screen or remotely. If the Open Output field
on the LineGuard Valve Control screen is not defined, the user must
manually open the valve on site.
LineGuard 2300 Program User Manual
Revised March-21 5
Valve Control
The control valve can be opened and closed both remotely and on-site by
setting the “Manual Close Flag” or “Manual Open Flag.” When the
“Manual Open Flag” is set the configured “Open Output” is energized for
the “Open Duration.” When the “Manual Close Flag” is set the configured
“Close Output” is energized for the “Close Duration.” “Open Duration”
and “Close Duration” values can be configured from 5 seconds to 1800
seconds (30 minutes).
Automatic valve closure can be initiated by a high-pressure condition, low
pressure condition or a high rate of drop of pressure condition. After autoclosure has been initiated, even a favorable pressure change will not de-
energize the “Close Output” and the valve will stroke to completion. Any
or all of these closure controls may be individually disabled if desired by
setting the “Auto-closure” for the alarm type to disabled. If auto-closure is
disabled, the program will still perform all other functions unless “Close
Output” is activated.
Limit switch inputs may be configured for both the open and close
operations. During valve closure the program will monitor the “Close Limit
Switch” status (if configured) and de-activate the “Close Output” when the
limit switch status becomes active. If the close limit switch input is not
defined, the close output will remain energized for the full close duration
period. During valve opening the program will monitor the “Open Limit
Switch” status (if configured) and de-activate the “Open Output” when the
limit switch status becomes active. If the open limit switch input is not
defined, the open output will remain energized for the full open duration
period.
Data Log Collection
Minor and major data logs are collected from the LineGuard unit using the
LineGuard Log Utility (refer to LineGuard Logs Utility User Manual
D301577X012). This software and associated documentation may be
purchased from Remote Automation Solutions. The interface software
allows the user to log-on into the LineGuard unit remotely or on-site and
retrieve logs. The utility is intended only for collection of minor and major
data logs from the LineGuard device. All other operations, including
program monitoring, program configuration, and event and alarm log
collection, are accomplished with the ROCLINK 800 configuration
software.
Input Error Detection
The program provides error detection for failed transmitters and input
power limits.
The user may enable a check for pressure transmitter fail detection (see tab
on the LineGuard Valve Control screen). The user enters low and high
pressure set points. When the transmitter fail check is enabled and the input
pressure is outside of one of the set points for more than a user defined
delay period, the program begins a transmitter reset sequence.
The program first cycles power to the pressure transmitter. If the pressure
value returns to within the set points, normal LineGuard operations are
continued. If the input pressure remains out of limits, the program initiates
LineGuard 2300 Program User Manual
6 Revised March-21
a restart (warm-start) of the FloBoss 107. If the pressure value returns to
within the set points, normal LineGuard operations are continued. If the
input pressure remains out of limits, line break detection software and
value closure algorithm are disabled until the pressure input value returns
to within the expected range.
The user may enable a check for input voltage error (see tab on the
LineGuard Valve Control screen). The user enters low and high input
voltage alarm limits. When the voltage check is enabled and the input
voltage to the FloBoss 107 is outside of one of the alarm limits, the
program first checks to see if a valve closure is already in progress. If a
closure is in progress, the program will wait for the closure to complete
before taking action. When the input voltage is out of limits and no closure
in is progress, line break detection software and value closure algorithm are
disabled until the input voltage returns to within limits.
