1.3 TD80 System Introduction and Description
1.3.1 About the TD80 System
The TD80 Level Transmitter is the heart of the TD80 level measurement
system. The TD80 transmitter uses Guided Wave RADAR (GWR) to
measure liquid level in a tank. It does not use any moving parts for level
measurement.
Guided Wave RADAR is a contacting level measurement method that uses a
probe as a wave guide to channel the radio frequency energy to the liquid
being measured. The probe provides an efficient path for the transmitted
energy and pulse reflections from the surface of the liquid.
The TD80 transmitter measures the time delay between transmitted and
reflected pulses to calculate distance to the material’s surface. This distance
is then used to determine level of the liquid in the tank.
The calculated level is converted into common volume units and is sent to a
Display such as the Finch 5332 Display. The display is also part of an
optional secondary overfill prevention system. TD80 generated alarms
provide the approaching overfill information to halt loading at industry
standard optic controlled loading racks, on-board loading pumps or valves.
The TD80 system consists of a TD80 transmitter, dual rod or coaxial probe
and a Finch Display. Optional components such as the Finch Relay Module,
horns and lights are installed as required.
1.3.2 TD80 System Components
TD80 Transmitter
The TD80 transmitter generates and processes the GWR signals to
determine liquid level in a tank. The TD80 is mounted on the tank top and
connected to the probe, is weatherproof and rated for use in hazardous
locations where explosive fumes may be present. TD80s are available in two
versions, dual rod or coaxial probe for compatibility with a wide range of
liquids.
Probe
The probe guides the transmitted pulse and reflection from the surface of the
liquid. Probes are available in dual rod or coaxial versions and require a
matching transmitter type. The probe is mounted on the tank top and is
connected to the bottom of the transmitter. Dual rod probes are designed for
viscous liquids. Coaxial probes are used mostly for tanks containing products
like aviation fuel.
Finch 5332 Display
Finch Displays are available in weather-proof external versions, the Finch
5332E and a smaller internal version, the Finch 5332. Both provide bright
LED numeric display of volume information, alarms and system error codes
from the TD80 transmitter. Various alarm and error conditions are detected
by the transmitter and display. These alarm states control three internal
relays for alarm annunciation, overfill and low level prevention.

1.3.3 Optional Components
P2000
The P2000 is an accessory that enables secondary overfill prevention when
used with industry standard optic loading rack controllers.
MIC 10
The MIC 10 is an interface device for connecting multiple TD80s to a third
party modem.
Finch Relay Module
The Finch Relay Module is an accessory that enables overfill prevention by
control of an onboard pump or loading valve.
Horns and Lights
Alarm reporting is through optional vehicle mounted horns and lights.
1.3.4 Theory of Operation
Overview
The TD80 system consists of a TD80 transmitter, dual rod or coaxial probe
and an internal or external Finch Display. Optional components such as
horns and lights are installed as required.
The TD80 continuously measures liquid level in the tank and transmits
volume information with alarm states to the Finch Display. This information is
presented on a large 4 digit display and to alarm controlled relays. Alarms
and errors control three separate relays to signal or control external devices.
These relays indicate Spill, High-High (HH) and system Fail alarms to
external devices such as overfill prevention valves, lights, horns and
stationary loading controls.
The HH, Spill and system Fail alarms provide information to the P2000 or
Finch Relay Module and only permits loading while all conditions are safe.
HH is normally the first shutdown level; Spill is a backup level slightly higher
than HH, while Fail indicates failure of the TD80 system. Activation of any
alarm halts loading to prevent a dangerous overfill condition or spill at the
loading rack.
TD80 Transmitter and Probe
The TD80 transmits a continuous stream of radio frequency pulses into the
probe. These pulses travel along the probe and part of the pulse energy is
reflected back to the transmitter when encountering the surface of the liquid
in a tank.
Time delay between the transmit pulse and reflected pulse is used to
calculate the distance from the tank top mounted transmitter to the liquid
level.

TD80™Level Gauging and Overfill Prevention System Product Manual
Page 8 TD80 Introduction/ Rev. 2, August 4, 2015
TPM 001
The TD80 contains a table describing the tank depth and volumetric
characteristics. This table is programmed before installation and operation on
the tank. Liquid level is calculated from the table using maximum depth of the
tank and distance from the top to the liquid surface. The TD80 “sees” the
depth of air space in the tank and calculates the loaded volume.
Physical limitations of GWR create a dead band at the bottom of the probe
where the transmitted pulse interferes with the reflected echo. This region of
dead band is considered to be the bottom 5.5” of the tank. Any liquid level
measured at 5.5” or less is indicated by the Finch as “2 LO”, meaning “too
low”. An upper dead band exists at 7.5” from the top on the dual rod and 2.5”
on the coaxial probe. Level measurements within the dead bands are
inaccurate and unreliable.
Calculated volume is transmitted to a Finch Display by SV Bus while a
linearly scaled level is sent by the optional 4-20mA interface. The Finch is
able to display up to 4 numeric digits, including a decimal point. This numeric
display correctly indicates volume of loaded product in the tank. The 4-20mA
output is scaled linearly for a volume of 0% at an output of 4mA and 100%
volume at 20mA.
SV Bus
SV Bus is a single wire serial digital communication interface with an error
checking protocol that eliminates false communication between the TD80
transmitter and Finch Display. SV Bus is one of the three wires required for
TD80 operation with the Finch. The other two wires are power and ground.
This bus is designed for reliable communications in stationary and transport
environments.
Finch Display
The Finch Display receives a continuous stream of volume information and
alarm states from the TD80 on the SV Bus. Volume, alarm states and errors
are shown on the 4 digit numeric display. An additional alarm is controlled
directly by the Finch. Alarms and errors control three separate relays to
signal or operate external devices.
TD80 controlled relays indicate Spill, High-High and system Fail alarms to
external devices such as overfill prevention valves, lights, horns and
stationary loading controls. The Finch controlled alarm and relay indicates a
preset, increasing Fill or decreasing Fall level to warn of an approaching
operator action while loading or unloading product.
The Fill/Fall and High-High Alarms remain active until acknowledged by the
operator. The Spill alarm remains active until the spill condition is cleared by
unloading product below the spill alarm level while the system is powered
and monitoring the changing level.
Alarms are acknowledged by button presses on the Finch or a push button
connected to the Alarm Acknowledge input.
TD80 reported errors or malfunctions are indicated by the Finch showing
“E xx”, where xx is an error code and activating the Fail alarm.
Finch reported loss of communication with the TD80 is indicated by showing
“----”and activating the Fail alarm.

Rev. 2, August 4, 2015/ TD80 Introduction Page 9
TPM 001
Relay Module
A Finch Relay Module is available to combine the Finch Spill/Fail and High-
High alarm relays with a signal from the vehicle mounted Power Take-Off
(PTO) to safely control an onboard overfill prevention system. The Relay
Module contains high current relays to energize a bottom loading valve or
hydraulic motor bypass valve for loading control. It also contains a terminal
strip for power and alarm accessory interconnections.
P2000
The P2000 is an accessory that enables secondary overfill prevention when
used with industry standard optic loading rack controllers. The Finch
controlled alarms provide an intrinsically safe signal to the P2000 that
permits or denies loading at the rack. The loading rack connections are
made through a standard 7-pin or 10-pin optic socket.
MIC 10
The MIC 10 is an interface device for connecting multiple TD80s to a third
party modem. Level, alarm and error information from the TD80s is collected
by the MIC 10 and forwarded to the modem. The modem is then able to
wirelessly transmit data to the back office for asset management and
tracking purposes.
It can be set to automatically transmit TD80 data at intervals based on a user
preferred configuration, or else can send data on command from the modem.
The MIC 10 features a PTO signal input to enable data transmission only
when the PTO is engaged. This limits the data bandwidth required by a
wireless modem.
1.3.5 The TD80 Alarm System
This description refers to TD80 transmitters and Finch 5332E/PS Display
(Red Terminal Board version). See notes in parentheses for the Finch 5332E
Display (Green Terminal Board version). Internal Finch 5332 description is
the same as the 5332E version. Internal Displays are connected by a pigtail
with labeled wires instead of a terminal board as in the external Finch
versions.
The TD80 alarms are listed below. A vehicle mounted Power Take Off (PTO)
unit may signal a loading or unloading event when alarms are required to be
activated. A Display Enable (PTO) (or Gauge Enable (PTO) on 5332E
Displays) signal to the Finch Display enables these alarms. An inactive PTO
signal holds all alarms in the non-alarming state to prevent false triggering
due to sloshing while driving. This PTO signal is usually a dry contact switch
closed by the mechanical engagement of the PTO.

Fill/Fall Alarm
Fill and Fall alarms share one relay output. The alarm is configured as a Fill
or a Fall alarm with Finch Display jumper J9. The alarm point is settable by
the operator. The Fill alarm is typically used to warn the operator when the
loading process is nearing maximum capacity. The Fall alarm is usually used
when unloading and a minimum volume of product must be retained in the
tank to prevent pump damage. Fill or Fall operation is determined when the
system is installed and is configured inside the Finch Display.
The Finch Display is the source of this alarm. Fill/Fall alarms are indicated by
the flashing the current level on the display and activating the Fill/Fall alarm
relay.
High-High (HH) Alarm
The High-High alarm is set during transmitter programming and is normally
the maximum safe volume of the tank. Dual Rod TD80 transmitters and
probes are settable to a volume from 8” below the tank top and lower while
the Coaxial TD80 transmitters and probes are able to be set from 3” and
lower.
The TD80 transmitter is the source of this alarm. The HH alarm is activated
by a measured volume equal to or exceeding the alarm level set during
programming. High-High alarms are indicated by alternately flashing “HH”
along with the current level on the Display and activating the HH alarm relay.
Spill Alarm
Spill is an approaching overfill condition. Dual Rod TD80 transmitters and
probes are factory set at 7.5” below the tank top while Coaxial TD80
transmitters and probes are selectable in the range of 2.5” down to 15.5”
from the top.
The TD80 transmitter is the source of this alarm. Spill alarms are indicated
by showing “SPill” on the display and activating the spill alarm through the
Spill/Fail (or Fail on the 5332E Displays) relay.
Fail Alarm
System failures such as internal transmitter errors, probe faults or loss of
communications are reported by the Spill/Fail (or Fail on the 5332E Displays)
relay.
The Finch Display reports communication failure. The TD80 transmitter is the
source for all other system errors. Errors are displayed as “E xx”, where xx is
an error code. Loss of communication between the TD80 and Finch is
displayed as “----“.
Alarm Relays
1. Fill/Fall relay
2. High-High relay
3. Spill/Fail (or Fail on 5332E Displays) relay.

Devices such as horns and lights are connected to these alarm relays for
operator action. The Fall, High-High and Spill/Fail relays typically operate
shutdown controls including external relays, and solenoid operated valves.
1.4 Overfill Prevention System Description
The description below incorporates the recommended Finch Relay Module.
See the Overfill Prevention System Installation Section 2.7 for detail.
1. Power On
The TD80 and Finch proceed through the normal start-up sequence as
described below. Once completed; “OFF” will be displayed on the Finch.
Level is displayed for 30 seconds by a momentary press of the Up or Down
buttons.
2. PTO Engaged
The operator engages the truck mounted PTO to begin loading. The PTO
signal to the Finch is controlled by an air/electric switch that causes the
following to occur:
1. Finch Display to an active mode with all alarms enabled and continuous
level display.
2. A Solenoid is energized to allow loading by controlling a Normally
Closed bottom loading valve or a Normally Open hydraulic motor
bypass valve.
3. The Green Light is on to indicate loading is permitted.
4. The Red Light and Horn are off at the start of the loading process.
Bottom Loading Valves:
The unpowered condition of a bottom loading valve is normally closed. The
solenoid must be powered to allow loading. Any alarm condition for system
errors, failures or overfill will cause the solenoid to be de-energized and halt
the loading process. A disengaged PTO will also close the valve.
Hydraulic Bypass Valves.
The unpowered condition for a hydraulic motor bypass valve is normally
open. The solenoid must be powered to allow loading by closing the bypass
circuit. Any alarm condition for system errors, failures or overfill will cause the
solenoid to de-energize and halt the loading process. A disengaged PTO will
also open the valve.
3. Operator fills the tank
The liquid is loaded into the tank using either the on-board or a stationary
pump. When the liquid reaches the Fill alarm level, the following occurs:
a. The Red light and Horn turn on to alert the operator that he is getting
close to the loading limit and has to prepare to turn off the pump and
close the valve.
b. The Green Light stays on to indicate continued loading is permitted.

TD80™Level Gauging and Overfill Prevention System Product Manual
Page 12 TD80 Introduction/ Rev. 2, August 4, 2015
TPM 001
c. The Solenoid continues to be energized to allow loading.
d. The Finch Display flashes the level indication to indicate the active Fill
alarm.
The operator then presses either the Up or Down button on the Finch to
silence the horn, turn off the Red light and return to a normal level display.
The operator continues to load. He will likely manually shut off the pump and
close the valve before the liquid level reaches the HH alarm level. If he does
not and the liquid level reaches the HH alarm level, then the following occurs:
a. Green light turns off
b. The solenoid de-energizes, closing the bottom loading valve or opening
the on-board pump bypass valve. This halts the loading process.
If the tank has been loaded to the required amount, then the operator turns
off the pump, closes the valve, disconnects the hoses and drives away.
If the tank has not been loaded to the required amount, then the operator
clears the HH alarm on the Finch with the UP/UP/DOWN/UP button
sequence. This resets the alarm response and allows further loading with the
following:
a. The Green Light turns back on
b. The Solenoid is re-energized
c. The Solenoid either opens the bottom loading valve or closes the on-
board pump bypass valve to allow loading to continue.
The operator is likely to stop loading before the level reaches the Spill alarm
level.
If the operator continues to load and reaches the Spill alarm level, the
following occurs:
a. Green Light turns off
b. The Solenoid is de-energized
c. The de-energized solenoid either closes the bottom loading valve or
opens the on-board pump bypass valve to halt the loading process.
The operator cannot reset or acknowledge the Spill alarm. The liquid must be
pumped out of the tank until it drops several inches below the HH alarm
level. The Spill alarm then clears and enables loading through a bottom
4. PTO Disengaged
When the operator has completed the loading procedure, he turns off the
PTO. This deactivates the Finch alarms, displays “OFF” and prevents the
solenoid from energizing to disable loading through a bottom loading valve or
a bypass valve on a hydraulic motor.
He now drives to a new location to load or unload.
