Section 2 - Theory of Operation and Description

The Anderson - Negele L3 Pressure / Level transmitter may be used in applications where an analog
output proportional to process pressure, hydrostatic head, or the volume or mass of a vessel’s contents
is needed for process or inventory control . This unit utilizes an internal piezoelectric transducer and an
RTD temperature element to measure the pressure and temperature of the internal actuating uid. The
mV signal of the transducer and resistance of the RTD are measured and converted to a compensated
pressure value by way of the signal acquisition board in the stem. This signal is digitally communicated
to the head where the signal is converted to industry standard 4...20mA and Hart 7.0 signals. For relative
sensors the back of the diaphragm is vented and the output is relative to the atmospheric conditions. In
the case of the absolute sensors the measurement is relative to a theoretical perfect vacuum therefore
the signal will vary with atmospheric conditions.

The integral display and four button interface shows the process variable, a graphical representation of
the output and allows reconguration of the unit including the conguration of tank geometry and product
density. All parameters may also be accessed through Hart communication.

The L3 Pressure / Level transmitter was designed specically for liquid measurement applications in the
food and beverage industry where accuracy in dynamic temperature environments is critical to process
control. The measurement cell is integral to a welded sanitary diaphragm seal that is available in a
variety of industry standard tting styles and sizes. The process pressure deects the metal diaphragm,
transmitting the pressure to a transducer cell.

Section 3 - Installation

The physical installation is of the upmost importance with regard to sensor reliability. Transmitters must
be installed in such a way that the device and cable are not subject to physical abuse. Additionally,
moisture and or moist air must not be allowed to enter the sensor housing or cable.

NOTE: The installer assumes responsibility for preventing water or water-vapor from entering the sensor
housing by proper installation of the cap and appropriate cable preparation. Units equipped with M12
Quick Disconnects are rated to NEMA 4X and IP69X. Cable gland equipped units are rated to NEMA 4X

and IP67.

To facilitate electrical connections, your new L3 transmitter may be supplied with a 5pin M12 quick
disconnect receptacle, an M16 cable gland, or a ½” NPTF threaded adaptor. If mounted horizontally,
the cable connection should point downward. Also, to prevent entry of excessive moisture, it is highly
recommended that conduits not be connected directly to the sensor. If conduit is to be run to the sensor,
it is preferable that the watertight connector provided with each sensor not be removed from the sensor.
Instead, run the exible conduit as near to the sensor as possible and utilize a seal-tight connector at the
end of the conduit. Allow a short amount of cable to run between the sensor and the exible conduit. This
isolates the sensor housing from the conduit system and any moisture it may contain. If the conduit is
connected directly to the sensor, the chances are high that the sensor will eventually fail due to excessive
water or water vapor entry into the housing.

NOTE: It is recommended that a sensor “Re-ZERO” be performed at time of installation. Refer to section

7.10, page XX for information on this procedure.
NOTE: It is recommended that a mA calibration be performed after installing a transmitter in a loop for

the rst time. Refer to section 7.9

Section 4 - Sensor Wiring

WIRING TERMINAL CONNECTIONS

WARNING! This unit accepts DC voltage only, connection to AC voltage can cause failure of the sensor

and/or risk of electrocution

For wet environments requiring IP67 or greater environmental protection Anderson – Negele strongly
recommends using the available shielded molded cord-sets utilizing the 5 pin M12 eurofast quick

disconnect.

Anderson - Negele supplied cable meets all requirements for shielding and compatibility with the L3 quick
disconnect receptacle. Anderson - Negele recommends a cable of 24 gauge, 4 conductor, shielded (Belden
#9534) or equivalent. Four conductor cable is utilized because of its roundness as well as providing
connections for the normally closed relay. A round cable provides a suitable seal when used with seal-tight
connectors, strain reliefs and rubber grommets. Irregular shaped cable does not allow for a watertight seal.

If utilizing customer supplied cable, select a round cable with 22-24 AWG wire and a shield. In order for the
Anderson provided seal-tight connector to seal on the cable, the O.D. of the cable must be between 3/16” and
1/4”. If smaller cable is utilized, a di󰀨erent neoprene bushing must be used (must be customer supplied).

If an alternate seal-tight type connector is going to be used, be absolutely certain that the rubber bushing will
adequately seal on the cable. Do not use a connector intended for power cable (large inside diameter) if the
sensor cable is only 1/4”. Be sure to use Teon thread tape when attaching the new seal-tight connector.

4.2 Direct Wiring

Direct wiring to the L3 transmitter is accomplished as follows:

1. Remove the housing cap and lift the hinged display lid by the pull tab to expose the terminals.

2. Insert the cable through the seal-tight connector, stripping back approximately 2 inches of sheathing

to expose the wires.

3. Two wires will be utilized for the loop connection and two will be used to connect the normally closed
contact. Normal color codes being RED (Loop +) and BLACK (Loop -); Green (switch side 1) and
White (switch side 2). Trim o󰀨 all unused wires, including the bare shield ground wire.

To prevent a GROUND LOOP condition, be sure the shield material and the shield ground wire
do not touch the sensor housing. Use an insulator such as electrical tape or heat shrink tubing if

necessary.

4. Strip the tips of the remaining wires back approximately 3/8 of an inch and twist strands (tinning is

highly recommended).

5. Using Figure 2, make the proper connections to the wiring connector (located inside the housing)

The general navigation scheme of the device is shown below:

Pressing the up and down arrows moves the highlighted item.
Pressing “E” while an item is highlighted selects that menu item
Pressing the “M” button moves back one level

PAGE 15

7.2 - Units

There are three units which may be chosen for the transmitter.

• PV – represents the units of the primary variable to be transmitted. This may be pressure, volume,
mass, or height

• Dimension – represents linear measurement units to be used when describing tank dimensions and
may be chosen in Inches or meters

• Density – represents the density or specic gravity units products will be described with.

7.2.1 Units Configuration for Pressure Output

If the transmitter is to be used as a pressure measurement device or as a hydrostatic level measurement
device with the following units of output this menu should be used: PSI, Bar, in of H2O, mm of H2O, mm

of HG, mBar, or kPA

If Pressure units will be used, dimension and density units do not need to be chosen as tank and product
congurations are not required.

T

Once the desired units are highlighted pressing the “M” button will store the selection and move up one
level in the menu. Once units are changed all unit dependent menus will change to those units. For

example: range, alarms, etc

PAGE 16

7.2.2 Units Configuration for Volume, Mass, and Height Outputs.

Units of height, (inches and mm) will scale relative to uid level compensated for density. Units of
volume and mass (KG, LB, Gallon, Liter, HectoLiter, PCT vol) will output linearly with respect to those
variables compensating for nonlinear portions of a vessel. The display will show the volume or mass
located below the bottom of the sensor when no product is present and will respond after product covers
the sensor diaphragm. Hectoliter option is available only on rmware revision L3H.01.06.0 and later.

To congure a unit for volume, mass or height outputs the following actions must be taken.

1. Choose the dimension units as shown:

2. Select the density units as shown:

*note SG refers to specic gravity

3. Complete the tank conguration as shown in section 7.4

4. Complete the product conguration as shown in Section 7.5

5. Return to the Units menu to congure the primary variable (PV) units as shown:

*Once a tank is selected and density is entered the full list of units is available

Once the desired units are highlighted pressing the “M” button will store the selection and move up
one level in the menu. Once units are changed all unit dependent menus will change to those units.
For example: range, alarms, etc Units of height, (inches and mm) will scale relative to uid level
compensated for density. Units of volume and mass (KG, LB, Gallon, Liter, PCT vol) will output linearly
with respect to those variables compensating for nonlinear portions of a vessel. The display will show
the volume or mass located below the bottom of the sensor when no product is present and will respond
after product covers the sensor diaphragm.

7.3 - Range

The Lower Range Value (LRV) and Upper Range Value (URV) may be chosen when the sensor is used
with pressure units. When height, volume, or mass units are used the LRV and URV are calculated
automatically but may be viewed to aid in PLC programming. The L3 is also capable of setting the span
based on the pressure applied to it (autospan).

7.3.1 Configuring Range for Pressure Ouput

The menu below shows adjustment of the LRV and URV for pressure output ranges. It should be noted
that the PV units should be set to the desired units before performing this action.

When the LRV or URV is displayed the Up and Down arrows may be used to adjust the value as desired.
The LRV may be set from vacuum to 0 for gauge sensors, except 5 PSI sensors which are adjustable
from -5 PSI to 0 (the LRV is not adjustable for absolute sensors).

The URV may be set from 10% of the sensor limit up to the sensor limit.

PAGE 17

7.3.2 Viewing Range for Volume, Mass, and Height Outputs

When in volumetric, mass, or height units the LRV and URV are calculated automatically based on the
tank dimensions and product density. The calculated values may be viewed as follows:

7.3.3 Using the Autospan Feature

The autospan feature may be used to set the URV based on the pressure on the sensor. This can only
be done when pressure is present or a vessel is lled to the desired upper limit. Autospan can only be
used with pressure units.

7.4.5 – Custom Tanks

If the desired tank geometry is not available or tank drawings or dimensions are not available a wet
calibration may be done to congure a custom tank. Please note this procedure requires a reference
ow meter and must be done sequentially while lling the vessel*. The user must decide the number of
points required and then pump the amount of process uid into the vessel and assign that value. The
process is a guided as shown below:

* Ensure product cong is set to

product being used for calibration.
i.e. Water, Skim Milk, etc.

The up and down buttons may be used to select the number of points and the volume or mass present in
the vessel.

7.5 – Product Configuration

Use of height, volume or mass units requires the selection of a product density. For the convenience of
the user 10 common products are pre-loaded on the device and an additional 5 custom products may be
stored at a time. When a new product is put in a tank it is important to change the product conguration
to avoid errors in output due to changes in density.

7.5.1 Selection of Pre-loaded Products

Pre-loaded products may be chosen from the product conguration menu as shown:

PAGE 21

10 products come pre-loaded with densities in the units chosen. Adjustments can be made with the up
and down buttons when the value is shown.

7.5.2 Configuration of Custom Products

If the customers product is not preloaded it may be programmed as one of the available 5 custom
products. Once congured with a name and density value the custom product may be highlighted to

select for use.

Up and down arrows increment characters and value. E moves to the next character and Long Hold E
moves to the Value. Alpha numeric values and symbols may be used in the name.

PAGE 22

7.6 – Alarm Configuration

The L3 has two available alarm congurations. Each alarm may be set up as follows. Alarms 1 and 2
have identical conguration menus. When enabled, if the alarm is activated the backlight of the display
will blink to notify the operator. The blinking feature can be disabled through the menu option. Also, alarm

activation can be delayed until process pressure/level is above/below setpoint for set period of time.

Alarm Flash and Alarm Delay options are available only on rmware revision L3H.01.06.0 and later.

7.7 – Switch Output Configuration

The L3 transmitter is equipped with a normally open 50mA fused contact which can be used to switch
a small load or provide a digital output when one side is provided with DC voltage. The switch may be
assigned to alarm 1, alarm 2, or may actuate when a warning or error message is displayed.

7.8 – Dampening

The analog output can be digitally dampened to decrease the magnitude of large process uctuations
with a high frequency. The dampening value should be raised when the output is showing high
frequency high magnitude uctuations. The dampening factor can be adjusted from 0-10.

7.9 – mA Configuration

The mA conguration menu contains options to adjust the loop output to match the control system
reading the signal, adjust the failure mode, and change the loop direction.

7.9.1 – mA Calibration

When a transmitter is added to a system for the rst time a mA calibration should be performed to ensure
the sensor’s 4mA and 20mA points align with the control system in which it is installed. Because input
cards are variable this will provide the best results and avoid programming an o󰀨set in the PLC.

The mA calibration requires the device to be installed in a control loop where the mA value may be read
by observed by the operator and the display may also be accessed.

PAGE 23

7.9.2 – Failure Mode Selection

The L3 may be set to fail low (3.8mA output) or fail high (20.2mA output) when a valid process variable

cannot be output.

PAGE 24

7.9.3 – Loop Direction

The loop direction may be reversed (20mA -4mA). This is accomplished as follows:

7.10 – Re-zero

The L3 transmitter is sensitive to both orientation and clamping forces during installation. It is important
to re-zero the sensor after it has been installed. Additionally, if the diaphragm is dented or goes through
a period of stress such as being steamed for the rst time, it is important to zero the sensor.

7.11 – Factory Reset

If at any time the owner decides to go back to factory default settings there is an option to return the
sensor and transmitter to their defaults separately.

7.11.1 – Sensor Reset (Stem)

When the sensor is reset it restores all factory default calibration information including any user o󰀨sets

7.11.2 – Transmitter Reset (Puck)

The transmitter may be restored to factory defaults as well. This will reset all ranges, alarms, tank, and

product data.

7.12 – Device Information

Through the device information screen the owner may access the following information:
Serial number, upper range limit (URL), lower range limit (LRL), device type, puck rmware revision, and

sensor rmware revision

Section 8 - HART Communicator Connection & DD (Device Descriptor)
Menu Structure

L3 transmitters can be equipped with an optional HART output protocol and may be addressed via an
external HART modem or alternatively via a portable HART communicator (HHT) compatible with HART

7.0.

8.1 Attaching HART Communicator

1. Power the L3 Transmitter. The signal loop must have at least 250ohms resistance for HHT function

2. Connect the HHT across the transmitter terminals or the resister loop

3. Turn on the HHT, wait until communications are established and the Home Menu is displayed

8.2 HART DD Menu Structure

All L3 functions as well as standard HART setup detail may be addressed via the HART DD menu. See
following Menu DD for specic required paths.

Section 9 - Maintenance/Diagnostics

Warning! Do not remove this sensor from the process while it is operating. Removal while the process
is operating can contaminate the process and could cause human injury.

Warning: Before removing for service or calibration, ensure that residual product has been ushed from
the line and that internal pressure has returned to atmospheric pressure.

Anderson electronic sensors require very little maintenance, if any. We suggest that the sensor be
inspected at 6 month intervals to ensure that they are not being subjected to physically abuse, moisture
entering the housing, and that the wiring is sound.

Caution: Do not open the sensor enclosure in wet or spray-down environments. Moisture ingression can

cause premature electronics failure.

External cleaning instructions: The external surfaces of this sensor can be cleaned along with the
equipment or piping system that it is installed on, using cleaning and disinfecting solutions designed for
use on hygienic equipment.

PAGE 29

The L3 is equipped with diagnostic routines that monitor the sensor’s function. Should an error occur
the diagnostic display will ash an error code and the output will go to the failure state specied by the

user. Errors may be caused by a number of reasons ranging from failed electronic components to user

conguration errors. The code appendix below indicates possible codes with actions that should be taken
to correct the problem. Error codes may be cleared to facilitate subsequent menu changes, however the
output will remain at the specied failure state until error is addressed and the unit repowered. Always
record the error code before attempting to clear it.

The display code may be erased as follows:

• From home screen press down and hold for several seconds. Some error codes will not erase until
problem is resolved – Sensor displays current process value.

• Power cycle by removing power for 10 seconds then reattach power.

Caution: Improper replacement of components during service can result in process leakage, reduced
pressure rating, system cleanability issues, incorrect output signal, or error code(s).
