1.0 INTRODUCTION

The X76CTM Continuous Electronic Tank Moni­toring System is designed to tighten inventory con­trol of fuels and other liquids stored in underground
and aboveground tanks. The probe, controller and
sensors form a system that measures fuel height,
fuel temperature, water height, and leakage.It will
also provide information on gross and net fuel vol­ume, leak alarms, and time and date of the leak.
Information acquired automatically provides faster
shift changes by eliminating the need to manually
stick the tanks and generate manual reports.This
reduces human error and makes it possible to spot
losses by theft, leaks, or meter miscalibration.The
system provides a highly reliable tool for a sound
inventory management practice.

2.0 GENERAL DESCRIPTION

The X76CTM features a 2 line by 24 character
alphanumeric LCD that provides instant information
for each tank including: product volume and level,
product temperature, water level, and time and
date.The X76CTM also provides reports, alarm
warnings (utilizing the LCD display), an alarm LED,
a printer, and output relays.

The X76CTM performs in-tank leak detection test­ing through a continuous statistical leak detection
algorithm, which eliminates the need for unnec­essary and costly station shutdown for in-tank tests.

Once the power-up and configuration of the
X76CTM System are complete, the operation of the
controller is automatic. Check to make sure that the
paper is locked into the printer feeder.The system
is ready for user login and monitoring.

IMPORTANT: Information provided by the X76CTM
should be used as part of a conscientious inventory
control program. If loss of product is identified by
the Leak Detect Test, call for a precision tank test.
Do not excavate tanks or take other remedial action
based solely on X76CTM inventory or leak detec­tion reports. While the X76CTM is capable of
detecting leaks as small as 0.1 gallons per hour,
the system is testing only that portion of the tank
containing product at the time of the test. Call for a
precision tank test to confirm a suspected leak.

NOTE: If an ‘overfill tank tightness test’ is to be
performed to confirm a suspected tank leak, the
95040XB Gauge Probe must be removed from the
tank.The system warranty will not cover damage to
the probe resulting from an overfill condition.

3.0 SAFETY RULES

3.1 Intrinsic Safety

Hazardous atmospheric mixtures include all
explosive or ignitable air mixtures involving
gases or vapor at an atmospheric pressure
and with ambient temperatures between zero
and 120°F. The order of ignitable materials
generally corresponds to the National Electri­cal Code groupings.The wor kable categories
and test materials used typically for each are:

Group A: Acetylene (8.7% by volume)
Group B: Hydrogen (21.0% by volume)
Group C: Ethylene (7.8% by volume)
Group D: Methane (8.2% by volume)

The ignition capability of an electrical circuit is
determined by the electrical energy available
and the manner in which such energy is
released. Energy may be released in the form
of a spark, by resistive heating effects or a
combination of the two.There are three basic
mechanisms by which electrical energy may
be released in the form of spark discharge:
discharge of a capacitive circuit, interruption of
current in an inductive circuit, and make-break
of a resistive circuit.The minimum ignition
energy for any flammable mixture is the small­est amount of energy released as a spark and
sufficient to ignite the mixture at 0 psig.

The most easily ignited air mixture is that
mixture of flammable material in air which
requires the minimum amount of energy for
ignition.The flammable material is usually
designated in percentage by volume in air.

Normal operating conditions include maximum
supply voltage and the extreme environmental
conditions that fall within the ratings given for
the specific equipment under investigation.

Abnormal operating conditions usually refer to
any two mechanical or electrical faults occur­ring in combination.The faults are independent
and include accidental damage to, and failure
of, components or wiring.

Intrinsically safe electrical equipment and
associated wiring are incapable of releasing
sufficient electrical or thermal energy under
normal or abnormal operating conditions to
cause ignition of a specific hazardous mixture
in its most easily ignited concentration in air.
The flammable material may be a gas or
vapor.

Underwriter’s Laboratories, Inc.approvals are
based on examination and test of samples of

to do so could create danger to life and prop­erty and result in voiding all warranties con­nected with this product.

WARNING:

1. Conduits or wiring troughs from probes and
sensors to the controller must not contain
other foreign wires.No other wiring is per­mitted with the probe wires and leak sen­sors in the intrinsically safe area of the
system.

2. The conduit run from the probe to the con­troller must not exceed 2,500 feet. See
Installation diagram X76D518.

3. All conduits must enter the controller
through the threaded hubs provided.

4. Do not install the controller in a volatile,
combustible, or explosive atmosphere.

5. The X76CTM System must be installed
in an environment that is within the operat­ing specifications of the system.

NOTE: The controller must be located in a
general purpose environment with a mini­mum temperature of 32°F. Check the sys­tem specifications for further information or
call Ronan Engineering for assistance.

6. All external equipment used with the sys­tem must comply with the National
Electrical Code for the area where the
equipment is being installed.This is particu­larly important when selecting external
horns, push buttons and relays to be used

Failure to comply with these warnings
could result in serious injury, property loss
and equipment damage.

3.3 Intrinsic Safety Check for Warranty
Registration & Checkout

Refer to the installation drawings in the back of
this manual for details.

1. Check to be sure that probe wires are con-

tained in a separate, dedicated rigid con­duit.The conduit and wiring troughs from
the probe or liquid sensors to the controller
must not contain any other wires.

2. Make sure the probe to controller wiring

does not exceed 2,500 feet.See the instal­ation drawing for proper wiring require­ments. All conduits must enter the controller
through the threaded hubs provided.

production quality equipment and inspection of
manufacturing and quality control facilities. Of
particular consideration are the adequacy of
design and workmanship, uniformity and
dependability of production, effectiveness of
quality control, functional suitability, assurance
of availability of service, and replacement of
parts.

Installation of intrinsically safe monitors makes
it mandatory to maintain complete isolation
between the field contact wiring and any other
potential source of voltage.

To be completely assured of an intrinsically
safe installation of the X76CTM, all equipment
used must be installed by a Ronan Authorized
Service Contractor.The installation, including

8.0 SETTING T ANK DAT A

The configuration of the X76CTM is designed to be
performed in sequential steps. Because every step
uses the data from the previous step (particularly
for tank parameter settings), it is important to follow
the steps below:

1.Configure tank geometry.

2.Configure the probes.

3.Configure the product.

4.Configure initial product levels.

5.Configure tank-based alarms: low, low-low,
high, high-high and maximum water level alarm.

Configuration of the station’s name and address, the
contacts, relays, the annunciator, and the product
information is order independent and can be done at
any time.

9.0 BROWSING & PRINTING

EVENT HISTORY

The X76CTM uses flash memory to store all of the
events. The event storage capacity is approximately
3000 events. In the event of overflow, the oldest
events are discarded.For typical station use, this is
about 2 years usage.Each event is time-stamped
and identified including users logged in at the time.
The X76CTM stores the following types of events:

Power Up. Each time the X76CTM is powered up, it
stores the date and time of power up.

User Login or Logout. User name and the date
and time of the event is logged in.

Contact Event. Contact number and state (alarm or
normal).

Tank Volume and Level Events.Low, low-low, high,
high-high, and high water stored, as well as the
state (alarm or normal).

Leak Test Results. When a leak test is completed,
records the test duration, leak rate measured, and
date and time of the test. Leak tests are star ted
automatically during quiescent conditions.The
X76CTM stores all of the results, and uses them for
Continuous Statistical Leak Detection (CSLD).

To browse the event history, use Function 100.It
always starts with the last event.Scroll through the
events using [HI, LO] keys. Press the [PRINT] key
and the X76CTM will print the event displayed on
the screen. If [PRINT] is pressed again, the
X76CTM prints the next 20 events. After pr inting the
events, the X76CTM will wait for [PRINT] to be
pressed again for the next 20 events, or [HI, LO] to
continue scrolling.

Events can be filtered by type, date and time. This
feature enables the user to make customized
reports. To select the type of events to be seen, use
Function 101. Select the type of event by using [HI,
LO] keys.Press [ENT.]. Select the start and end
times.The start time is by default the current time
minus 24 hours, and the end time is the current
time. Once changed to different values, the settings
will remain in effect. If C/CE is pressed while editing

the times, the time is cleared and assumed not to
be used for filtering. If the event is tank specific, a
prompt for selecting the tank will be displayed
(some events like contact, login, and logout are not
tank related). After selecting the filter, the filtered
events will be browsed the same as F100.

43, Delivery Threshold

When a product is delivered to a tank, the X76CTM
senses it and writes the date, time, amount, and
temperature of the delivered product.Sometimes, a
small amount of product pouring back in the tank

during transfer is not considered as delivery.To min­imize confusion, the user can set up a value that
will eliminate the small levels. The default threshold
is 200 gallons. Use Function 43 to change the
delivery threshold and press [ENT.] to save.

Delivery threshold

100.0 gl

..

75, Leak Detect Threshold

X76CTM has 4 leak-related alarms: Quick Test,
Precise Test, High Leak, and CSLD (Continuous
Statistical Leak Detection).The function for each of
these alarms may be programmed independently
using F82.

The Quick Test is star ted automatically after a pre­defined, probe-dependent interval following a deliv­ery (1 hour for X76MP, 7100, MTS-UST and
Veeder-Root MAG2).The result is compared to a
probe-specific threshold and, if a failure has
occurred, an alarm is generated.Testing immedi­ately after a delivery is not precise, although still
within the EPA requirements. Ronan recommends
this result only as a leak indication, not as a basis
for programming station shutdown.

The Precise Test is run after a longer waiting period
following the deliver y.It guarantees more accurate
results and a lower number of false alar ms. Two
thresholds are possible for this test corresponding
to the 0.1 and 0.2 gallons/hour EPA requirements.
The thresholds are set automatically, and are probe
dependent. Normally, a station shutdown procedure
is specified for this alarm.

The High Leak alarm is activated whenever a gross
leak is detected.The leak must be higher than
9 gph, and lower than the minimal pump through­put. High Leaks occur when a pipe is broken, or the
tank is physically damaged.The High Leak detec­tion alarm time is shor ter than a leak test, typically
less than 30 minutes.

The CSLD alarm is activated when long-term data
shows possible tank leakage.It is useful for busy
stations that do not have time to run a full test.
Since the result of the CSLD test is based on the
database compiled by short tests, it cannot be used
to confirm a leak. If a CSLD alar m occurs, the tank
must be shutdown and a full test, preferably a
Precise Test, has to be run.

To set up the leak test parameters, select F75.
Pressing [ENT.] at ever y parameter confir ms the
current value.

Leak scatter is a very important parameter, since it
defines when the tank is quiescent, and a test can

68, Manifolds to t# 12345678

The X76CTM allows for the combining of two or
more tanks to generate the combined product vol­ume of physically manifolded tanks. If tank 2 is
manifolded to tank 1, the reports for tank 1 will
contain the manifolded volumes, while those for
tank 2 will not.The same applies to the leak test.
The leak test for tank 1 will use the combined
product volume, while tank 2 will be independent.

Manifolding tanks is performed with Function 68.
The display has 8 characters for every tank where
the current tank is marked with a black block.

Manifolds to t# 12345678
1-8 to set/clr: ...* ...

Press the key, corresponding to the tank number to
be manifolded, to toggle the status of the tank (i.e.,
if tank is not manifolded, it will manifold and vice
versa). Pressing the digit that corresponds to the
current tank does not cause a change.To end
manifolding, press [DISPLAY].

..

76, High-Water Level Alarm

The high water alarm is set using Function 76.

High water level alarm

3.5 in

The high water alarm warns when the water level
has exceeded a preset level. When this set point is
exceeded, an audible/visual alarm is generated fol­lowed by a printout of the alarm.The high water
alarm can be programmed to an external output
relay (Function 81). Information on the last water
alarm warning for each tank is stored in memory.

..

79,Theft Detect Threshold

Use Function 79 to set up the theft detect thresh­old. A message will be displayed:

theft gallon alarm active and press [ENT.].

NOTE: This function is only active when in THEFT
DETECT MODE (Function 292).

..

82, Set Up Tank Alarm

The X76CTM can be configured to perform differ­ent actions when an alarm occurs. For each event,
a relay can be assigned.The events supported
are:

be conducted.The higher it is, the easier it is to
enter a leak test, but the data could be noisier and
the results incorrect

.

Leak scatter

0.2 gl

The activity threshold is used to distinguish tank
leakage from real activity - delivery of sale. It can
be increased to the minimal throughput of the dis­penser pump.By default this is 9 gl/h.

Activity threshold

9.0 gl

Temperature scatter controls what temperature
slope is acceptable to start a test.

Temp scatter

0.2 deg/h

Minimum test duration sets the minimum accept­able test time to be used by the CSLD database.

Min test duration
15 min

A maximum test duration of 120 minutes is suffi­cient for tanks up to 20,000 gallons.Increasing this
duration usually will not improve the result and
degrade the response time.

Max test duration
120 min

Precise wait after delivery can be entered to in­crease the test precision, although it is not needed
in most cases.

Precise wait after delivery
360 min

This parameter allows the X76CTM to use a lower
threshold for the Precise Test. Generally, this
increases the probability of false alarms, but allows
for early warning of possible tank leak.

0.1 gph test? No

The minimum CSLD duration sets a minimum com­bined test time for the CSLD algorithm to make its
conclusions. Generally, the longer it is, the better.

Min CSLD duration
8 hours

The minimum history parameter sets the maximum
number of days to be used by CSLD to acquire the
minimal test duration. If there is not enough tests
for this period, increasing the number of days is
recommended. If it is not possible to acquire the
data for one month, the tank should be shutdown
and a normal test conducted.

100, Browse Events

This function is used for uncondition­al and unfiltered display of the events
from the event log, always beginning
with the most recent event.

To browse the event history, use
Function 100.This display defaults to
the last event.To scroll through the
list of events use the [HI] and [LO]
keys.Pressing the [PRINT] key
prompts the X76CTM to print the
event that is on the screen.If
[PRINT] is pressed again, the next
20 events will be printed.After print­ing those events, if [PRINT] is
pressed again an additional 20
events will print, or [HI] and [LO] can
be used to continue scrolling through
the event history.

..

101, Event Filter Query

Use this function to selectively dis­play events from the event log, fil­tered by type, start/end times, and
tank. Browse the list of available
event types. Select the event type
with [HI] and [LO]. Use 255 for all
event types.

Event query 255 filter
All

Enter start and end times to select a
specific range of events. The end
time (the most recent event) is dis­played first.If an end time is not
entered, the system defaults to 24
hours from the start time:

Query event: start
9/18/99 13:00:00
Query event: til
9/19/99 13:00:00

If a query by start/end time is not
required, press the clear key [C/CE]
to bypass this filter.

The system will prompt for tank filter
if the event type is per tank based.

Filter by tank

103, Print Report [HI, LO]

Function 103 prints a hard copy of the following report selections:

1. Active Alarms Report. Prints all alar ms that are currently
active (all active contacts and tank level limit set points).

2. Inventory Report. Prints the current level, volume, and tem-
peratures for all active tanks.

3. Shift Report. Similar to the inventory report, but also includes
the net change of the volumes and the temperature since the
last time this report was printed. Normally it is printed every
time the shift changes.The date and time of the last report are
also printed.

4. Daily Sales Report. Prints the average daily sales for each
day of the week for the last month, as well as the number of
days remaining until the tank reaches low level, based on the
average sales.

292, Enable Theft
Monitor

The theft alarm is defined as
the activity of the tank (sale or
withdrawal) when the tank is
declared as inactive.To star t
theft monitoring, use Function

292.The current net volume is
recorded and the system moni­tors the net volume for changes.
If the net volume decreases
more than the threshold value
(default 10 gal), a theft alarm is
generated.The net volume
change will be recorded. For
every occurrence, the amount is
recorded, until the function is
disabled.The theft monitoring
can be disabled using Function

291.

Modbus™ Register Allocations

trator can access and alter the user codes.
Function 62 is used to change the PIN codes.
During new code entry, the numbers are sub­stituted with asterisks (*) on the display for
additional security. The administrator should
first log in, then enter the new user number.
This starts the login procedure for the new
user.When Function 62 is pressed, a prompt
for entering the user’s PIN will appear.

For example:To change the PIN for user 4,
log in as administrator, pressing 0.Enter the
PIN code for administrator.The default dis­play will appear. Press 4.The X76CTM will
prompt to enter the user 4 PIN number.Dis­regard prompt and press Function 62.The

system will prompt again for the new user 4
PIN number. Enter the new code.

10.2 Modbus™ Support

The X76CTM supports Modbus™ protocol in
both ASCII and RTU modes.The mode is
selectable via the front panel or the text ter­minal interface.For constant reading of the
tank information, the RTU mode is recom­mended because of the small data overhead.

10.2.1 Register Allocation. The system data
accessible through Modbus™, is on a per
tank basis.The variables are sent in IEEE
4 bit floating point format or as 4 bit scaled
integer long numbers, for devices that do not

21

support the floating point format. Although
the Modbus™ register in the Read Multiple
Registers Command (03) is 16 bit wide,
each floating point or unsigned long number
will occupy 2 registers.The register alloca­tions for the tanks are shown in the table
on page 20.

The last registers are reserved for future
use.The data for the next tanks occupy the
next 350 registers at 50 registers per tank,
with the same register allocations

INSTALLATION INSTRUCTIONS

Install the JT-2P Positive Pressure Leak Sensor or
JT-2V Positive Vacuum Leak Sensor on the tank
interstice riser.All other tank ports must be sealed
with #150 class pipe fittings.Teflon paste type
sealer is suggested for all threaded joints.

Provide electrical conduit, two each #18 AWG
wires to sensor input terminals of the Models
X76S, X76VS, X76LVC, X76LVCS, X76ETM, or
X76CTM tank monitors. Contact the brown and
blue sensor wires (N.O. position). Intrinsically safe
wiring must be in a dedicated conduit only. No 115
Vac or other wiring is allowed in the same conduit.
Pressurize the tank interstice with compressed air

or nitrogen, (DO NOT USE OXYGEN), or evacuate
the tank interstice through the JT-2P or V fill and
relief valve manifold (provided with the sensor) to

2.9 psig or 10 inches Hg.When the pressure or
vacuum has been applied, the system alarm will
return to normal.

NOTE: When filling the tank annulus with com­pressed air or nitrogen, the sensor fill and relief
manifold MUST be used. Never exceed 3 psig or
the tank warranty may be void.

WARNING: The red wire, (N.C. position) MUST be
capped off to prevent a short circuit to ground.
