Specifications
The Rack Monitor 8800E/8801E is a loading rack monitoring system, detects and communicates an overfill
condition to the loading rack control automation equipment by means of a normally open relay contact. In addition
this non-permissive condition as well as diagnostic information is displayed. A typical system contains loading rack
control monitor (88xxE Rack Monitor) and a API 10 wire screened coiled cable with a black 10 pins 4 J-slot plug
(Model 7400E).
Thermistor and optic signal inputs allow compatibility with the NEN-EN13922 and two other API standard signalling
conventions commonly used in the industry. Either of these signals comes from the truck/trailer mounted onboard
control monitor or sensors. The 88xxE rack monitor supersedes the 84xx and 85xx type rack monitors and are
suitable for hazardous locations with intrinsically safe outputs.
There are two versions available. The Rack Monitor 8800E is a complete version with liquid crystal display. And the
Rack Monitor 8801E version without a liquid crystal display.
The installation of both versions is the same.

Product Description.
This manual describes the operation, and troubleshooting of the Civacon 8800E/8801E Loading Rack Monitoring
System.
Read separate installation manual for wiring the rack monitor
It is intended to help operators, maintenance persons, and equipment specifiers understand the operation and
standard features of the 8800E/8801E Rack monitor
It is recommended reading this manual before installation of the equipment.
The 8800E/8801E monitor is a loading rack monitoring system designed to offer a reliable and safe assistance
when loading a tank truck.
It can detect and work with a wide variety of overfill sensors but can also be set to accept only sensors conform.
EN13922 Tanks for transport of dangerous goods
Service equipment for tanks
Overfill prevention systems for liquid fuels
The 8800E monitor is designed to interface with the user by means of a large multi languages Liquid Crystal
Display and Light Emitting Diodes indicators (LED)
A clear and short message will be shown on the Liquid Crystal Display to explain the status of the overfill sensors,
cabling and Rack monitor.
The 8801E monitor is designed to be used where environment does not meet the necessary temperature
specifications when the monitor is switched off.
Note: For simplicity the manual will refer to the standard 8800E Rack monitor with
Liquid Crystal Display. and therefore all information mentioned as shown on the
LC-Display must be ignored when a 8801E is used.
Both 8800E and 8801E are standard equipped with a high quality blue cord set and a black 10 pins plug. An
junction box (Model 7500 Series) can be ordered as an option. Passive (and active) storage plug hangers are also
available.
Please consult the factory for the current availability of all optional products. Thermistor and Optic signal inputs
allow compatibility with the European standard EN13922 as well as the two API standard signalling conventions
commonly used in the industry. Either of these signals comes from the truck/trailer mounted onboard control

Sensors Types.
Two-Wire Thermistor Sensors. (NTC)
Two-Wire sensors.
Five-Wire sensors.
Sensors and Grounding.
Before continuing describing the functionality of the rack monitor a short explanation of the sensors and ground
verification.
As mentioned above there are three industrial standard sensor principals.
There are two industrial standards for the Two-Wire sensors.
A Thermistor sensor with a negative temperature coefficient (NTC) and a Two-Wire optic or compatible sensor. The
Thermistor sensor is basically a heating element in combination with a temperature sensor.
The Thermistor sensors are heated up to approximately 75°C (167°F) (Depending type).
Time to heat the sensor depends on ambient temperature and used Thermistor type.
( how the 8800E will handle the Thermistor is explained later in this document).
The sensing circuit of a 2 (and 5) wire sensor are not necessarily done with a optic detection circuit. To avoid
misunderstanding this manual will refer to Two-Wire sensors and Five-Wire Sensors. Two-Wire sensors can be
used on vehicles with no more then eight compartments. Standard Rack monitors are monitoring all 8 channels
(see Dipswitch setting for 6 channels US version). This means remaining channel(s) on vehicles equipped with
Two-Wire sensors with less then 8 compartments must be connected to a electronic Dummy (e.g. part number
1920). All sensors are individual Wired / connected to the Rack monitor and more than one wet compartment can
be detected at the same time.
The Five-Wire sensors are connected in series and therefore capable of handling more then 8 compartments.
Because of this, only one wet compartment can be detected at the same time. A special diagnostic wire is used to
determine the wet compartment. The 8800E can handle more then 12 compartments but only 12 will can be
indicated on the LED display.
(Maximum 12 compartments according EN13922)
The 8800E will try to determine which compartment is wet if more than 12 compartments are used and if a good
connection is made between plug and socket and wiring are done carefully, the 8800E shall indicate the correct
compartment on the Liquid Crystal Display.
Note: Displaying the correct wet compartment is only possible if there are no bad connections.
Ground verification is done via pin 9 on the terminal and plug-socket connection.
For NEN-EN13922 application pin 9 is also used for detecting if a Vapour recovery hose is properly connected to
the Tank-Truck when five-Wire sensors are used.
Note: The Vapour recovery hose is checked via pin 8 on a Tank-Truck equipped with Two-Wire sensors.
Note: Consult socket drawings for detailed information.
The 8800E Rack Monitor is capable of (auto-)detecting a resistive Ground connection as well as a Ground-Bolt
(EL00001-E) connection on a Tank-Truck. Make sure connection between pin 9 and pin 10 via the Tank-Truck
chassis is less then 1kΩ.
The two wire Thermistor sensors are simple component sensors with no active elements. This means the Rack
monitor has to control the Thermistor sensor where a two-wire optic or compatible sensor has active elements and
is self oscillating when dry.
As soon as the 8800E rack monitor has detected the Thermistor sensor it will supply power to heat the Thermistor
bead from ambient temperature to a predefined high temperature this will be indicated on the LC-Display with a “H”
and also the green indicators will flash from low intensity to high intensity. As soon as the thermistor bead reach the
predefined high temperature the 8800E will switch off the power. The Thermistor will cool down until the predefined
low temperature is reached. When a the Thermistor bead becomes wet the 8800E is not able to heat the Thermistor
bead within the specified time and switch to NON-permissive.

System operation.
The purpose of the Civacon 8800E Rack Monitor liquid level sensing system is to detect a liquid point level signal
from a sensor mounted in compartments of a tank truck, or storage tanks. The system provides an automatic signal
to the rack automation equipment to shut-off the flow of liquid and warn of an impending overflow condition of a tank
truck or storage tank It can detect up to 8 Two-Wire Sensors or 12 Five-Wire Sensors
As soon as the power is supplied, the monitor will perform a extensive self test of its internal functions (see power
up test). If one of the test fails (except Led Test) a message will be shown on the Liquid Crystal Display. Also a red
Led indicator will blink. (see troubleshooting chapter for details).
Make sure no vehicle is attached at power-up.
Note: The cable and plug connections shall be tested if a active storage hanger is used.
If all tests are passed the rack monitor is ready for use.
The first task of the 8800E Rack Monitor is to ensure proper grounding is established via Pin 9 and pin 10 of the
plug socket connection to the tank-truck chassis. As soon as this has been ensured, two white Led indicators will
flash inversely. Secondly the 8800E will check for shorts between sensors and shorts to ground for every channel
and for open circuits. Then the 8800E Rack Monitor will determine sensor type and the amount of compartments. It
can detect up to eight thermistors or Two-Wire sensors, up to 12 Five-Wire sensors and is fully compatible with the
3204E Onboard Retain Overfill Monitor.
If possible, the amount of sensors will be shown on the Display and Led indicators. ( see sensor detection chapter
for details).
The 8800E Rack monitor provides an “Auto switching” capability between Two-Wire sensors, Two-Wire Thermistor
sensors and Five-Wire sensors.
If sensor type is selected, all sensors are dry and proper ground is verified the 8800E Rack monitor will
communicates a Permissive condition to the automation equipment. When Thermistor sensors are used a waiting
period has to be observed.
Of course the monitor can only be connected to one type of signal source at any one time. You cannot have Two &
Five-Wire sensors connected at the same time. Although the 8800E/8801E Rack Monitor can detect and operate
with a mix of Two-Wire sensors (Thermistor and self oscillating) it is not recommended.
The 8800E Rack Monitor systems uses self-checking principles to provide a continuous check on all system
components. It also checks short circuits between sensors and ground and open circuits when connected to a tank-
truck.
If at any time the 8800E Rack Monitor detects any kind of failure, a signal to the automation equipment will be send
to shut-off the flow
All sensor failures are indicated on the two displays.

Normal operation.
The main task of the 8800E Rack Monitor is to provide a signal to the rack automation equipment to shut-off the
flow of liquid as soon as a sensors in a compartment tank detect a liquid point level
When the rack monitor is not used for 15 minutes it goes into sleep mode.
During sleep mode the Red Led indicators will be dimmed and occasionally flash with high intensity to indicate “
system ready in sleep mode”.
As soon as the Plug is connected to the truck socket or removed from the active storage hanger the system awakes
and is ready for use. If proper ground and dry sensors are detected the rack monitor will switch to permissive. When
the loading is finished and the plug is removed from the truck it will wait 15 minutes before it goes back to sleep.

As soon as the plug is connected to the truck the following message page will appear.
(e.g. truck with Ground bolt and Two-Wire Dry sensors)
In line 4 the type of ground verification: Ground Bolt
In line 5 the type of sensors: Two Wire Sensors
In line 6 the amount of sensors:
In line 7 the state of the detected sensors: Dry
If all sensors are dry and a proper ground is verified the indication “permit to load “will appear at line 10.
If less then 8 sensors are connected and the remaining sensors are emulated with a dummy the rack monitor will
indicate the remaining channels as dry Two-Wire sensors.
Note: only when special Dummy is mounted in the socket of the Tank-Truck. Else remaining channels will be
indicated as Dry

Sensor detection.
The 8800E and 8801E rack monitor is an auto switching rack monitor and will detect automatically the 3 types
commonly used overfill sensors. Before the rack monitor switch to permissive the following steps will be performed.
1. Individual short detection between sensors and ground.
2. Resistive ground detection via pin 9
3. Ground bolt detection via pin 9
4. Sensor type detection
5. Detected sensors complies to EN13922
6. Detected sensors complies to Rest Of the World specifications (ROW)
7. Detected sensors appears to work but not complies to the above specifications.
Note: Overfill sensors commonly used in industry are not necessary compatible with commonly used Rack
Monitors in industry.
The specification of the ROW overfill sensor are based on an extensive worldwide sensor collection. All
parameters of those sensors are collected and the boundaries are stored in a table inside the 8800E/8801
Rack monitor.
Note: The European Standard EN13922 describes the following points.
- Functions
- Major components
- Characteristics
- Test methods
Note: in some cases the rack monitor is still able to use the connected sensor as an overfill detection device. The
operator will be asked to accept the detected sensor by using the Blue bypass key.
Step 1.
In this step the rack monitor is checking if all wires are connected to a sensor and there are no shorts between
channels.
E.g. If on the tank truck one sensor is connected to two pins on the socket or one dummy channel is used to
emulate two dry sensors the Rack monitor will detect this as a short and show this on the LC-Display.
Step 2. & 3
Although ground verification is continues it is mention in this document as a step.
Since many Tank-Trucks are equipped with a ground bolt the 8800E/8801E Rack Monitor will accept this
automatically as a proper ground verification.
Be aware that conform the EN13922 in combination with Five-Wire sensor(s) the earth verification is
connected in series with the vapour recovery hose interlock switch
Step 4.
The Rack monitor will apply power to the sensor and analyze the measured signal.
In case of a Two-Wire Thermistor sensor, a special algorithm will be used to heat the sensor to his operating
temperature. This will be shown on the LC-Display with a H at Line 7
Also the Green LED indicator will change intensity until operating temperate is reached.
Note: Time to heat the sensor depends on ambient temperature and used Thermistor type.
07 S E N S O R S T A T E : H H H H H H H H
If no Two-Wire sensors are detected, power will be applied at channel 8 and a pulse will transmitted at pin 4
If a return pulse is detected the rack monitor will continue with Five-Wire senor(s).
