VULCAN SINGLE LINE (VSL) TECHNOLOGY
V300 SERIES ELECTRONICS SYSTEM
Vulcan On-Board Scales can be installed on all types of vehicles including, hook lifts, logging trucks,
flatbed trailers, chip trailers, front loaders, rear loaders, side loaders, roll-offs, transfer trailers, and
many other commercial vehicles requiring scales. Axle group weights, payload weights, and gross
vehicle weights can be measured using the Vulcan On-Board Scale System. The V300 Series consists
of two models: the V320 two-channel meter and the V340 four-channel meter.
The Vulcan On-Board Scale System consists of:
• Load Cells, Pressure, or Transducer Sensors - to sense load, air, hydraulic, or deflection
pressure.
• VSL Vulcoders - to convert the signals from the sensors to weight and communicate with
the meter.
• V300 Series Meter - to display the weights and run the scale system.
The number of VSL Vulcoders and the model of V300 Series Meter needed depends on the number of
channels required. The number and type of load cells or sensors needed depends on the truck’s
configuration, such as length, type of suspension, load capacity, etc. Only one V300 Series Meter is
required per truck.
The new Vulcan Single Line (VSL) technology is a revolutionary way that the V300 Series Meter
communicates with each VSL Vulcoder. VSL technology uses a single 2-wire cable to provide the
communications between the meter and VSL Vulcoders. The single 2-wire communication cable
sends power and set-up data to each VSL Vulcoder while receiving weight data from each VSL
Vulcoder.

CHAPTER 1
LOAD CELLS AND PRESSURE SENSORS
Vulcan load cells and pressure sensors are machined from solid blocks of high strength steel. The
Strain gages are bonded inside the load cell or pressure sensor to sense extremely small dimensional
changes in the material. A strain gage is a precision electrical resistance element. When force is
applied to these sensors, the strain gages stretch or compress, causing a change in output signal
voltage. This signal voltage is measured by the VSL Vulcoder and then used to determine weight.
Example: Vulcan Super - Beam Load Cell

VSL VULCODERS
The VSL Vulcoder is specifically designed to be used with the V300 Series Meter. The functions of
the VSL Vulcoder are to supply power to the load cells or other sensors and receive the analog voltage
signal back from them. A computer inside the VSL Vulcoder then calculates the weight based on the
calibration values, the “Tare Weight”, and the “Cal” number for that particular channel, which are
stored in its memory. When the meter requests weight from a channel, the proper VSL Vulcoder will
respond and send the weight information back to the meter. All VSL Vulcoders connect to the same
single 2-wire cable. Any VSL equipped trailer can be plugged into any truck with a V300 Series
Meter and be immediately identified and read properly.

V300 SERIES METER
Application: For vehicle combinations with one to four channels of weight sensing. The V300
Series Meter provides a high visibility display and the ability to easily read different trailers. The
V300 Series Meter is available in two channel (V320) and four channel (V340) configurations.
The V300 Series Meter uses VSL technology to power and communicate with VSL Vulcoders on a
single 2-wire cable. The meter requests weight information from the different Vulcoders. It then
displays individual channel weights and total weight as requested by the operator. The weight can be
displayed in pounds or kilograms. The meter also transfers all setup and calibration information for
up to four independent channels (A, B, C, and D) into the VSL Vulcoder, where it is stored.

CHAPTER 1
EXPLANATION OF METER CHANNELS
The V300 Series Meter can display information on up to four channels: A, B, C, and D. There is a
VSL Vulcoder for each channel. The number of channels is based on the number of load cells and
their grouping. For example, a trailer could have as many as four load cells per channel. The display
code tells the meter what channels to display. For more information on how to select the meter
display code, refer to Section 2.3 “Set Display Code”.
Refuse or Logging Truck Applications:
Typically, a refuse or logging truck application usually requires only one or two channels, A or A and
B. Channel A usually represents the truck or front load cells regardless of the number of load cells
connected to the VSL Vulcoder. Channel B usually represents the trailer or rear load cells. The total
weight for both the front and rear load cells is represented on Channel A+B.

ELECTRONICS INSTALLATION
1.
Tape the VSL Vulcoder connectors prior to routing the cabling to avoid contamination. Mount
the VSL Vulcoders on the inside of the truck frame rail or next to a structural member. The
VSL Vulcoder mounting surface must be in an area protected from road and hauling debris.
2.
Route the black cable to the load cells. (Do not trim the black cable to length).
3.
Important: Check the connectors to make sure they are clean and dry. Do not get moisture,
contact cleaner, or any other substance inside of the connectors.
4.
Check the load cell connector coming from the VSL Vulcoder for an O-ring. Attach the black
cable connectors to the bulkhead connectors on the load cells. Make sure they are finger tight
plus an additional 1/8 of a turn more with channel lock pliers. The additional tightening is
necessary to compress the O-ring. This prevents scale errors, which can occur from moisture
entering into the load cell connector. Caution: Do not over tighten the connectors as this can
damage them.
5.
Route the single 2-wire orange VSL Vulcoder cable from the meter in the cab to the last VSL
Vulcoder in the system. Be sure to route the cable to the meter and do not trim any excess
wire off at the meter. Trim off the excess cable to approximately 1' - 2' of extra orange cable at
the location of the VSL Vulcoder splice to allow for the splice. Note: On a truck-to-trailer
connection, these wires may be routed using the existing truck-to-trailer wire harness if two
unused, ungrounded wires are available. Additionally, you may follow the existing wire
harness and use a separate connector of your choice between the truck and trailer. If using the
separate connector, for the best and most reliable connection, connect each color wire to two
pin connections. For example, connect the green wire to the top two pins of a 4-pin truck-totrailer connector, and the white wires to the bottom two pins.
6.
Connect the first VSL Vulcoder in the system to the 2-wire cable by splicing each color-coded
wire from the communication cable and the VSL Vulcoder cable, (refer to Figure 1-J). When
using the Vulcan supplied 3M connector, do not strip the insulation from each wire. Be sure
to insert wires completely into the connector and check their position by looking through the
translucent connector body. Crimp the connector cap down flush with the top edge of the
connector body, ensuring a good connection. Tape the connection and all of the wires with the
orange insulation stripped off to help seal and prevent wire chaffing that can cause a wire to
short. Wire tie the splice so that the connection is strain relieved.
7.
Find a suitable location for each additional VSL Vulcoder needed in the system. Connect
additional VSL Vulcoders in the system to the 2-wire cable by splicing each color-coded wire
from the communication cable and the VSL Vulcoder cable (refer to Figure 1-J). When using
the Vulcan supplied 3M connector, do not strip the insulation from each wire. Be sure to
insert wires completely into the connector and check their position by looking through the
translucent connector body. Then crimp the connector cap down flush with the top edge of the
connector body ensuring a good connection. Tape the connection and all of the wires with the
orange insulation stripped off to help seal and prevent wire chaffing that can cause a wire to
short. Wire tie the splice so that the connection is strain relieved.

CHAPTER 1
Figure 1-J: VSL Vulcoder Communication Connection
8.
Once all of the Vulcoders have been installed, the Vulcoders must have either the wire loop cut
or uncut. Cutting the loop wire will designate the Vulcoder as a Front Vulcoder (refer to
Figure 1-K) and not cutting the Vulcoder designates the Vulcoder as a Rear Vulcoder (refer to
Figure 1-L). Following this procedure will enable the meter to properly assign channels. For
example, on a 2-channel system with the truck having a Front Vulcoder, and the trailer having
a Rear Vulcoder, the meter will sequence the Front Vulcoder as channel A, and the Rear
Vulcoder as channel B.

Find a suitable location for the meter and install the mounting bracket. Secure the VSL
Vulcoder cable so it does not obstruct other in cab equipment and strain relieve. Unplug the
terminal block from the back of the meter, strip the wires, and connect the VSL Vulcoder wires
to the terminal block (refer to Figures 1-M and 1-N). Secure the power cable so it does not
obstruct other in cab equipment, strain relieve the power cable, and cut to length. Strip the
wires, and make all wire connections to the terminal block (refer to Figures 1-M and 1-N). Do
not plug the terminal block into the meter at this time.
10.
Disassemble the positive fuse holder, (red wire). Apply grease to the positive connector at the
battery post to inhibit corrosion. Connect fused power leads directly to battery posts 12 Vdc
only. Refer to Section 7.2 “System Specifications”. Do not connect the power cable to a
power source activated by the key switch; power must be supplied at all times.

V300 SERIES - PROGRAM MENU (SYSTEM SETUP)
2.1
ENTERING THE PROGRAM MENU
The V300 Series Meter program menu enables the user to:
• Program Sequence (PS) - Assigns the proper sequence to the Vulcoders in the system, (Section
2.2).
• Program Code (PC) - By selecting a program code, the user tells the meter what channels and
combination of channels to display, (Section 2.3).
• Program Units (PU) - Selects the units of measure, either pounds or kilograms, (Section 2.4).
• Program Graduation (PG) - Selects the graduation for displaying weight, (Section 2.5).
• Program Cycle Time (PCt) - Selects the channel cycle time (Section 2.6).
• Program Lock (PL) - The lock must be in the Off position to adjust the Tare or Calibration
settings for the scale. Turning the lock to the On position will prevent changes to the system’s
calibration (Section 2.7).
To Enter the Meter Program Menu:
Press the PWR / MENU button to turn on the meter.
After the meter has completed its start up routine and is running, press the PWR / MENU
button to enter the program menu.
Press the CYCLE button to go through the different program modes.
Note: If the PWR / MENU button is held too long, the meter display will display all 8’s and the meter
will turn off.
2.2
SEQUENCING CHANNELS
The V300 Series electronics makes it possible for a truck to haul various types of Vulcan VSL
equipped trailers with “plug in and go” ease. To do this, the VSL Vulcoders need to be assigned their
position (channel A, B, C, or D) in the scale system. Once the Vulcoder has been assigned its
position, it will remember it and the process of sequencing does not need to be repeated, unless the
position of the Vulcoder changes. Sequencing is the process in which the meter determines the order
of each VSL Vulcoder or groups of load cells. For example, on a long logger, the meter reads the
Front VSL Vulcoder and assigns it as channel A, and then reads the next VSL Vulcoder as a Rear and
assigns this VSL Vulcoder as channel B.

CHAPTER 2
After entering the Program Menu, the first mode displayed will be Program Sequence (PS). If a
combination of “F” and “r” appears on the display, then the meter has detected the VSL Vulcoders.
For example, “PS FrFr” would indicate that four Vulcoders were detected, where “F” indicates a
front VSL Vulcoder and “r” indicates a rear VSL Vulcoder. The associated channel indicators will
also be illuminated.
Note: On new installations, the system will attempt to automatically sequence the Vulcoders. If the
attempt is not successful, (i.e. more than one Front or Rear Vulcoder is hooked up when the meter is
turned on) an Error code will be displayed (i.e. Err 03, Err 07, Err 08, or Err 09). If this happens, the
system will have to be Manually Sequenced.
2.2.1
MANUAL SEQUENCING
Manually disconnect all trailer VSL Vulcoders as shown in figure 2-A, and confirm that if the truck
has two Vulcoders, that one is set up as a Front and one as a Rear per installation instructions, section
1.5.
Figure 2-A: Disconnected Trailer
With the meter in the Program Sequence (PS) mode, press and release the CAL button to
start the sequencing mode. The meter will find and sequence the truck Vulcoders in a few
seconds and will display their front (F) or rear (r) designators. Manually connect each
trailer, starting with the most forward trailer connection. As each connection is made, the
meter will verify each connection with either an “F” indicating a front VSL Vulcoder, or an
“r” indicating a rear VSL Vulcoder.
If the “PS - - - -” (“PS - -” on a V320 Series Meter) appears on the display, no VSL Vulcoders are
detected.
Press the CYCLE button to store the sequencing information. The meter will then advance
to the next programming function.
2.3
SETTING THE DISPLAY CODE
The number of VSL Vulcoders connected to the Vulcan system corresponds to the number of
channels. The first number in the display code is the number of channels. The next two numbers or
letters determine how the channels will be displayed. When code 000 is selected, the meter
automatically selects the display code depending on how many VSL Vulcoders are communicating
with the meter at power up. The meter display code allows the user to display a combination of one or
more of the available channels. Refer to the list of display codes on the next page.

V300 SERIES CALIBRATION
Calibration is fine-tuning a system to maximum accuracy in reference to a specific certified platform
scale. It is important to calibrate the scales for high accuracy to achieve the maximum hauling
payload. Calibration consists of setting the appropriate Tare weight and Calibration number for each
channel.
It is important that conditions remain as constant as possible throughout the calibration process.
Inaccuracies may result from differences in fuel load, ice, or mud build-up, number of people in the
vehicle, etc. It may take 2 or 3 attempts at calibration to achieve the optimum setting.
Calibration should be done anytime a system is installed, if there are continuous questionable
readings, or if meter readings repeatably do not closely match the certified platform scale weights.
4.1
WEIGHT MEASURING METHODS
The Vulcan Scale System can be used to measure weight by two different methods. These methods
are Gross Vehicle weight and Net Payload weight. In addition to these methods, Vulcan Scales can be
used to determine Axle Weight on certain on-board scale configurations.
Important Notice for Front Loader Refuse Truck Operators:
To avoid weight measurement errors, the forks must be in the down position and the body lift cylinder
pressure must be relieved at the time of measuring for all methods. The pressure relief valve should
be engaged during weight measurements. If the truck is not equipped with a pressure relief valve,
relieve the pressure manually. In addition, all packing should be done after the weight is recorded.
AXLE WEIGHT
Vulcan Scales can be used to reduce overweight fines by measuring a vehicle’s axle weight. For some
vehicle configurations, such as many logging trucks and trailers, the channel weights will be the axle
group weight.
For other configurations, the channel weight may not be the actual axle group weights because other
axles are sharing some of the load. For short log and refuse trucks, the scales can indicate a weight on
an axle group that should not be exceeded in order to keep the truck legal. Load the truck close to the
legal maximum according to a certified platform scale. The number displayed on the channel of the
meter corresponding to the axle group represents an approximate rear axle group weight and may be
used as a reference weight to avoid exceeding the legal limit. This reference weight may be different
from the weight shown on the certified platform scale display. Note: Channel “A” does not represent
the steering axle weight when fully loaded.

4.1.1
CHAPTER 4
GROSS VEHICLE WEIGHT
Gross Vehicle weight:
Entire truck weight including fuel, equipment, personnel,
and payload.
In order to use the Gross Vehicle weight method, the Tare weight for each channel must be entered.
The Tare weight is the weight of the empty truck with fuel, equipment, personnel, and no payload.
For example, if the Tare weight is 30,000 lb, the meter will display this weight before any payload has
been loaded. As the payload increases, the weight displayed on the meter will also increase. For a
V320 2-channel system (A and B) the total Gross Vehicle weight is displayed on Channel A+B. For a
V340 4-channel system, the total Gross Vehicle weight is displayed as Channel A+B+C+D.
4.1.2
NET PAYLOAD WEIGHT
Net Payload weight:
Weight of the truck’s payload only.
By using the Net Payload weight method, payload pickups are measured cumulatively. Net Payload
weight can be measured when the truck’s Tare weight is set to zero for each channel. The weight
displayed at all times is the Net Payload weight.
4.2
PROCEDURE FOR ENTERING TARE WEIGHTS
GROSS VEHICLE & NET PAYLOAD WEIGHT METHODS
To properly calibrate a V300 Series system, all channels in use need to be calibrated. Listed below is
a procedure for entering the Tare weights. The Tare weights must be entered for each channel.
IMPORTANT: The truck and trailer must not be in a twist or turn while entering the Tare weights.

Calculate the Net weight for both the Certified Scale Readings (P) and the V300 Series Meter
reading (V) by subtracting the truck empty weight from the truck fully loaded weight.
P = Weight shown on Certified Scale (truck fully loaded) - Weight shown on Certified Scale
(truck empty)
Example: (P = 56,240 lb - 35,000 lb = 21,240 lb)
V = Weight shown on V300 Series Meter (truck fully loaded) - Weight shown on V300 Series
Meter (truck empty).
Example: (V = 55,000 lb - 35,000 lb = 20,000 lb)
7.
If the average difference between the certified scale and the meter is more than several
hundred pounds, you may want to adjust the Calibration Numbers. If so, proceed to Step 8.
8.
To determine the new Calibration Number for each Channel refer to the formula shown below:
New Channel Cal Number = Old Channel Cal Number x (P / V).
Example: Old Channel Number = 2050
P= 21,240 lb (Certified scale net weight).
V = 20,000 lb (Vulcan scale net weight).
New Channel Number = 2050 x (21,240 / 20,000) = 2177
9.
The Calibration Number for Channel B is the same as the Calibration Number for Channel A.
Channel B New Cal Number = Channel A New Cal Number
(Example: Channel B New Cal Number = 2177)
10.
Record the new Cal Numbers in Section 7.4, “Keeping Records” located in the Appendix.
11.
Repeat this procedure for other channels if they do not directly represent axle group weights.
(Example: C and D)

PREVENTIVE MAINTENANCE AND VULCAN
TORQUE SPECIFICATIONS
The following simple, but important, preventive maintenance steps must be performed
periodically. For example, after the first 500 miles, then monthly, or more frequently, if needed.
1.
Look for mud, ice buildup, or other debris between the load cell and bracket. Refer to location
A, shown on Figures 5-C through 5-L.
2.
Check load cell connectors (refer to location B shown on Figures 5-D through 5-L); make
sure they are finger tight plus an additional 1/8 of a turn with channel lock pliers. The
additional tightening is necessary to prevent scale errors, which can occur from moisture
entering into the load cell connector. Do not grease or lubricate inside the Vulcan load cell
connector or VSL Vulcoder connector. These components are highly sensitive to foreign
substances and inaccurate readings will occur if these components are contaminated. Your
manufacturer’s warranty does not cover the failure of Vulcan components due to
contamination (use of grease or other conductive substance) in either the Vulcan load
cell connectors or VSL Vulcoder connectors. If a connector is opened for any reason, you
must clean the load cell connector and cable connector with cotton swabs and isopropyl
alcohol, dry with a hair dryer (DO NOT OVERHEAT), and replace the O-ring before
reconnecting.
Note: In areas where salt is used on the roads, wrap the threads of the load cell connector with
plumber tape, (Teflon tape). This will not allow salt to penetrate the threaded connection.
3.
Check the torque on load cell cap screws monthly. New trucks must be checked once a
week for 2 weeks. Vulcan On-Board Scales recommended torque values are shown on
Figures 5-C through 5-L and general torque values shown below. As a method of monitoring
changes in fastener torque, Vulcan On-Board Scales recommends applying torque stripes to all
fasteners (see Section 5.1, step 2).

4.
Vulcan load cells are plated for increased rust protection. Certain minimum maintenance will
be necessary to claim warranty of load cells. Annually, apply a high quality paint to the load
cells, bearing pads, and mounting brackets. For environments where high concentrations of
salts are used on road surfaces, undercoating is recommended (3M, Universal Rubberized
Undercoating, 3M P/N: 8883). Spray undercoating when load cells are connected to
electronics and fully assembled with bearing pads and brackets. See “Vulcan Load Cell
Maintenance” document 44-20006-001 for further details.
5.
Fill unused holes in load cells with grease, to protect against rust. Never grease the inside of
the connector.
6.
Check welds on load cell brackets. IMPORTANT: If a weld repair is required, remove the
load cell. CAUTION! Do not exceed 140 degrees Fahrenheit (60 C) on the load cell.
Arcing on the body of the load cell voids the manufacturer’s warranty and may seriously
damage the load cell’s structural integrity. The load cell must NOT be installed if this
occurs.
7.
Tipper Trucks: Keep bearing surfaces greased preferably with a Moly Disulfide type of grease.
8.
Check and grease the rear hinge pin / pillow block assembly.
9.
Check all wiring for condition, routing, and protection.
10.
Check meter for secure mounting and strain relief of wires.
11.
Check system for functionality.
12.
Review and address any driver concerns.

TROUBLESHOOTING
In general, troubleshooting is a systematic process of testing and eliminating potential problem
sources until the one that is causing the problem is found. Repairing or replacing the faulty part can
then fix the problem.
With a little knowledge and by following a step-by-step procedure, most of the problems that you may
encounter will be easy to diagnose and solve. In this section, you will find guidelines on how to
troubleshoot the system, some characteristics of a properly functioning system, and where to look
when certain problems occur.
Occasionally, someone has a problem that is not described here. Do not panic. By approaching the
problem systematically, you will be able to eliminate potential sources of trouble until you find the
one that is causing the problem.
The following section covers an explanation of V300 Series Test Procedures, Load Cell Evaluation
Test Procedures, and Vulcan V300 Series Error Codes. If a problem occurs and no Error Codes
appear, use the V300 Series Meter to isolate the problem to the appropriate channel.

VULCAN CHECK-OUT BOX
The Vulcan Check-Out Box can be used to check load cells and the electronics. It works as an
extension to bring load cell connector pins to the side of truck where readings can be conveniently
made. It can also simulate an applied load to the VSL Vulcoder. The Check-Out Box is an optional
equipment item for the Leakage and Resistance Tests (Section 6.3.1 and 6.3.3).
Before using the Check-Out Box, make sure the meter fuses are good. Use a multi-meter to ensure
there is a minimum of 10.5 Vdc at the back of the meter when the system is running. (Make sure the
green plug is plugged in and the meter is turned on.) If there are any error messages displayed, refer
to Section 6.4 “V300 Series Meter Error Codes”.
Figure 6-A: Vulcan Check-Out Box
To order a Check-Out Box (P/N: 56-10425-001), contact your Vulcan dealer.

LOAD CELL EVALUATION TESTS
The tests listed below will help identify and locate any problem you may encounter with your Vulcan
load cells.
Leakage Test
Tare Test
Resistance Test
6.3.1
LEAKAGE TEST PROCEDURE
Required Equipment:
Optional Equipment:
Digital Multi-Meter with Conductivity Scale
Isopropyl Alcohol
Cotton Swabs
Hair Dryer
Vulcan Check-Out Box
The Leakage Test Procedure detects the presence of moisture that could cause erratic meter readings.
The way to measure leakage is to use a digital multi-meter that has a conductivity scale. Electrical
isolation is measured between any pin and an unpainted clean surface on the load cell or the connector
body. Electrical isolation must not exceed 2.0 nS (nano-siemans) or be less than 500 Meg Ohms.
Refer to Figure 6-B for the Leakage Test equipment setup. If a Vulcan Check-Out Box is used, it is
important that the VSL Vulcoder leads from the load cells of the channel being tested are
disconnected.
For proper operation, the power and signal leads from the load cell must have a very high resistance to
the load cell body. An electrical path between the wires and the body would indicate moisture in the
cell or shorting to the body. This would result in erratic, fluctuating, or even out of range weight
displays.
If the load cell fails (electrical isolation is greater than 2.0 nS or is less that 500 Meg Ohms), check the
inside of the load cell connector with a dry cotton swab to make sure it is clean and dry. If not, clean
with isopropyl alcohol, dry with a hair dryer, and check the electrical isolation again.
If the load cell cannot be brought to Vulcan specifications, contact your Vulcan dealer.

Press and release the TARE button again.
Press and release the CAL button. The CAL and LOCK LED’s are illuminated.
Record the current Cal Number.
Current Cal Number: _______________
Change the Cal Number using the S and T buttons to display 2050.
Press and release the CAL button again.
Disconnect one load cell from the VSL Vulcoder of the channel to be tested.
Plug that one lead into the connector on the Check-Out box. Make sure the load switch is pointing
away from the red dot. Note: The Check-Out box is needed to properly zero the electronics. Note: If
the Check-Out box is not used then you may receive incorrect readings. Disconnect the Check-Out
box. Clean and re-connect the load cell to the VSL Vulcoder.
The meter will display the load cell preload number. The preload number should not exceed
+12,000 lb to -12,000 lb.
If the preload number is within +12,000 lb to -12,000 lb, again using the Check-Out box to re-zero the
meter, test the next load cell in the same manner. If the preload number is within specification for all
load cells, reconnect and secure all load cell leads. Reset the current Cal Number then reset the
current Tare weight. Note: If the preload number is out of specification, clean the load cell connector
and cable connector with cotton swabs and isopropyl alcohol and dry thoroughly with a hair dryer and
DO NOT OVERHEAT the connector.
Check the electrical isolation of the load cell by performing the Leakage Test, (Section 6.3.1).
Reconnect the lead to the load cell. Reset Tare to "0" and repeat test for that load cell.
Check the Preload Number again to see if it is within the +12,000 lb to -12,000 lb range. If the load
cell is still out of range, it may be faulty. Perform the Resistance Test, (Section 6.3.3).
If the load cell cannot be brought to Vulcan specifications, contact your Vulcan dealer.

CHAPTER 6
6.4.13
Err 13
Indicates too many Vulcoders on the transmit side were detected in an RF (Radio Frequency) Remote
System. For example, a V320 Meter on the transmit side may have up to one standard Vulcoder and
an RF Remote Transmit Vulcoder attached. If the receive side is a V340 Meter, it can only have three
standard Vulcoders on the transmit side. Therefore, the 2-channel V320 Meter cannot read all of the
4-channels of the V340 Meter.
Possible Causes:
1.
2.
Too many VSL Vulcoders attached to the VSL line.
Faulty VSL Vulcoder
What to Do:
1.
Verify the number of VSL Vulcoders attached to system. The V320 Meter is limited to one
standard Vulcoder and one RF Remote Receive Vulcoder. The V340 Meter is limited to three
standard Vulcoders and one RF Remote Receive Vulcoder.
2.
Verify sequencing, manually sequence if necessary, Section 2.2.1.
3.
Replace VSL Vulcoder.
6.4.14
Err 14
Indicates V320/V340 Meter did not detect the VSL Set Point Vulcoder.
Possible Causes:
1.
2.
3.
4.
New Installation – Vulcoder must be manually sequenced.
Communication problem between Meter and VSL Set Point Vulcoder.
Cables have been disconnected or damaged.
Faulty VSL Set Point Vulcoder.
What to Do:
1.
Verify the number of VSL Vulcoders attached to system. The V320 Meter is limited to one
standard Vulcoder and one RF Remote Receive Vulcoder. The V340 Meter is limited to three
standard Vulcoders and one RF Remote Receive Vulcoder., manually sequence if necessary,
section 2.2.1.
2.
Reconnect any cables that have become disconnected.
3.
Inspect VSL Vulcoder Communication line for cut or broken wires and proper connection of
the green and white wires. To check for an open VSL line, ohm the VSL Vulcoder line by
twisting the green and white wires together at the back of the meter and disconnect each
Vulcoder from the VSL Vulcoder line. There should be no resistance detected when
measuring between the green and white wires at the Vulcoder hook up point.

SYSTEM MALFUNCTIONS
6.5.1
CONDITION: No Indicator Display or Function Lights
Possible Causes:
1.
2.
3.
4.
5.
6.
7.
8.
Power switch turned off.
Power to the meter has been disconnected.
Bad meter cable connections to the battery.
Battery is low (under 10.5 Volts).
A fuse is blown in the power or ground cable.
Faulty power switch.
Reversed polarity
Faulty meter.
What to Do:
1.
Check the power to the meter. When the meter is turned on and off, the power should not
change more than 1/2 Volt at the back of the meter. Turn off the meter for a few seconds and
then turn on again. If the meter still does not work, proceed to step 2.
2.
Check the fuses for both negative and positive leads. Use only 1 amp fast blow fuses for 12
Vdc V300 Series systems only.
3.
Check that the power supply wires are attached correctly at the 12 Volt power source and to
the green connector at the back of the meter. Check the battery connections for corrosion.
4.
If a spare meter is available, the quickest and easiest next step is to exchange the meter. If the
new meter works, try the old meter again. If the old meter now works, the problem was likely
the meter’s internal circuit breaker. If both the old meter and the new meter do not work, the
problem is most likely in the power source (battery, meter power cable, or fuses). If the new
meter works, but the old one doesn’t, the old meter is faulty.
If you do not have a spare meter, disconnect, and then reconnect the green power plug on the
back of the meter. If the meter doesn’t work, then check the power source (battery, meter
power cable, or fuses). If the power sources check out, then the meter is faulty.

2.
Verify at least one load cell is connected to the VSL Vulcoder.
3.
Check the fuses for both negative and positive leads. Use only 1 amp fast blow fuses for 12
Vdc V300 Series systems only. Blown fuses could indicate a shorted VSL line. Isolate the
short by disconnecting sections of the VSL line and checking for proper meter operation.
Another way to check for a shorted line is to disconnect the green and white from the back of
the meter. Measure the resistance between the green and white wire. It should be greater than
1000 ohms. This method can be used to check different sections of the VSL line to isolate the
short circuit.
4.
Inspect and replace any connection or 2-wire VSL cable that may show signs of being pinched
or crushed as this could cause either open circuits or shorted lines.
5.
To check for an open VSL line, ohm the VSL Vulcoder line by disconnecting and twisting the
green and white wires together at the back of the meter. Disconnect each Vulcoder from the
VSL Vulcoder line. There should be no resistance detected when measuring between the green
and white wires at the Vulcoder hook up point.
6.
To check for a bad Vulcoder, disconnect each Vulcoder from the VSL line and power up the
meter. If the meter powers up, connect one Vulcoder at a time and manually resequence the
Vulcoder before restarting the meter.
