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.
