GARNET Instruments 808-P2 Tank Level Gauge for Trucks Installation Guide

TANK LEVEL GAUGE FOR TRUCKS
Installation & Operation Guide

INTRODUCTION

1.1 Overview
The SeeLeveL 808-P2 Display is a gauge mounted on trucks, providing real-time liquid level readings from the sender bar. When utilized with the 810-TX sender bar, it additionally monitors the temperature inside the tank. It facilitates safe loading with controls for a customizable warning alarm, and emergency overfill shutdown protection. It can be used alone, or in conjunction with Garnet’s SpillStop or MultiRack systems. 1.2 Features and Benefits

• Works with the 810-X or 810-TX sender bar (installed within the tank).
• Fiber optic signals enhance safety and make it suitable for flammable liquids in hazardous locations.
• Mounts externally on the truck/trailer for easy viewing.
• Fluid level is continuously displayed.
• Liquid temperature viewable with a press of a button (810-TX only).
• Programmable alarm thresholds that can be configured for Normally Open or Normally Closed (24 VDC at 1A) and used for a warning horn or other suitable devices when the liquid level reaches a programmable threshold.
• Emergency shutdown control when liquid level reaches programmable maximum threshold.
• Can be used to control SpillStop or MultiRack for increased overfill protection.
• New features of the 808-P2 (Rev M) include compatibility with both the 810-X and 810-TX (coming soon), automatic configuration for each bar, displays temperature readings from the 810-TX Sender Bar, and an updated alarm circuit with resettable fuses to prevent damage from wiring shorts or connection to devices that exceed the available 24VDC at 1A current limit.
• The upcoming release of the 810-TX sender bar includes an increased resolution from 1/3” to 1/4”, along with temperature sensors providing fluid level temperature to +/- 0.5°C (±0.1°F), a field-replaceable battery module, and will require the 250-STAT-FLOAT. The SeeLeveL 808-P2 Rev M or newer is required to take full advantage of all the new features of the 810-TX.

QUICK GUIDE

2.1 Operation
The sender bar is installed vertically inside the tank. As the liquid level changes, the float will move up and down the sender bar. Magnets within the float allow the sender to accurately measure the position of the float, and translate that into the liquid level. Embedded temperature sensors also measure the liquid temperature. The liquid level and temperature are continuously transmitted to the SeeLeveL gauge through the fiber optic cable. The gauge displays the volume of liquid within the tank based on this reading. The temperature of the liquid can be viewed by pressing the button on the side of the display (810-TX only). If the button is held down for 2 seconds, the battery status of the sender bar is displayed.
Every tank shape is different, and the display can be set to common volumetric units such as gallons, cubic meters, or barrels. To calibrate the SeeLeveL for your tank, please see the 817-USB SeeLeveL Truck Gauge Programmer documentation.

2.1.1 Alarms
The SeeLeveL contains internal alarm points that can be set to custom levels to warn the user when the liquid level is approaching its maximum level, and to shut off a pump if the tank is full.
As the liquid in the tank rises during loading, it will reach the warning threshold (alarm 2). When this happens, the SeeLeveL triggers the alarm 2 output. This output can be used to turn on a warning light, or horn, etc. This alarm can be bypassed by pressing the button on the gauge. If it is bypassed, it remains in bypass until the tank is emptied below the “reset” threshold (alarm 3).
If the liquid level increases to the “full” threshold, the emergency output (alarm 4) is triggered, which can be used as an emergency shutoff for a pump, to prevent overfill. This alarm cannot be bypassed.
The alarm will deactivate once the liquid level goes below the alarm 4 threshold.

ALARM FUNCTIONS

Enhanced overfill protection.
Programmable set point. (Green wire).
Alarm 2| Warning Horn| Programmable alarm. Will toggle on/off at the set point. Can be bypassed. While triggered if the bypass button is pressed the alarm condition will be latched until the tank level is brought below the set point for Alarm 3 (reset). (Purple wire)
Alarm 3| Auto Reset| Programmable reset. Will clear Alarm 2 once below the set point.
Alarm 4| Pump Shutdown| Programmable shut off. Will toggle on/off at the set point. Provides basic overfill protection and only used if the 808-P2 is being used in a standalone configuration. (i.e. without a SeeLeveL SpillStop). Cannot be bypassed. This alarm is used to lock out the pump. (Yellow wire).

2.2 View Firmware Revision, Mode and Temperature (Rev M)
To view the mode settings, ensure that the display is reading “ ”, then place a magnet over the “v” in “SeeLeveL” on the front label. Continue to hold the magnet and the display will begin to scroll through the menu. The magnet can also be placed on the backside of the lid where it indicates “place magnet here to change mode”.
View Firmware revision 8.19 or higher.
Once the magnet is in the correct position, the LCD screen will then display the Firmware revision. ‘r8.19’ or higher.
View Classic or Enhanced mode
If you continue to hold the magnet in place the LCD will then display the current mode for the calibration.
The 808-P2 will be in either classic “ “ mode or enhanced “ ” mode. Both modes allow for offsets and alarm points to be used, but enhanced mode offers some more advanced functionality. This setting can only be changed with the 817-USB programmer, and further details can be found in the 817-USB programmer manual.
View or set Temperature to Fahrenheit or Celsius
Finally, the menu will display the temperature setting. The LCD will display “ ” (Current Temperature Fahrenheit) or “ ” (Current Temperature Celsius). To change the temperature setting continue to hold the magnet in place. The LCD will display “ ” (Program Celsius) then “ ” (Program Fahrenheit).
Remove the magnet when the desired setting is display. The LCD will flash “ ”, storing the setting.

INSTALLATION GUIDE

3.1 Sender Bar Assembly

3.2 Tank Preparation
3.2.1 Determine sender bar mounting position

1. Select a central location in the tank for mounting the sender bar,  ensuring proximity to the tank’s midpoint and allowing space for the head at the top. (See Figure 3.2.1a)
2. Ensure the float won’t encounter any tank baffles or obstructions.
3. Preferably, position the float for hatch accessibility to facilitate service work; avoid mounting it behind baffles that restrict hatch access. (See Figure 3.2.1b)

3.2.2 Install NPT Collar and Float Support

1. Drill a hole and weld NPT collar into place at top of the tank.(See Figure 3.2.2a)
2. Mount float support at the bottom of the tank. Ensure NPT collar and anchor are aligned. For float support fabrication (See Figure 3.2.2b).

3.2.3 Cutting the Bar

NOTE: The sender bar needs to be cut to length for specific trailers.
Contact a sales or service rep for cut options.

3.2.4 Sender Bar Installation

1. Guide the sender bar through the NPT collar. Ensure the compression fitting is on the bar, then through the float anchor support until it hits the bottom of the tank.
2. Raise the bar 2” up from the bottom of the tank to accommodate tank flex that could mechanically interfere with the bottom of the bar. (See Figure 3.2.4a)

CAUTION: Installing the bar less than 2” from the bottom of the tank WILL result in premature sender bar failure that is not covered under warranty.

3.3 Mount the Display

1. Select a location for the display. It should be easy to see and out of direct road spray and protected from driving rain.
2. The display enclosure should be mounted using the mounting flange holes. If the holes are not pre-drilled in the display enclosure, drill holes into the enclosure close enough to the base to avoid contacting the lid flange (See Figure 3.3.4b).
3. Make sure that the lid is not on the box when drilling to avoid damaging the display electronics.

3.3.5 Connect the Airline Hose

1. At the lowest point in the airline, insert a T-fitting with approximately two feet of 1/4” airline hanging down to create a drain/vent for any moisture that may enter or build-up in the system.
2. If a T-fitting is not practical, install a fitting into the bottom of the display enclosure and route the 2 feet of 1/4” airline hose from there. (See Figure 3.3.5a)

3.4 Install Fiber Optic Cable
3.4.1 Preparation of Fiber Optic Cable

1. Use a piece of 1/4” airline hose to protect the black fiber. With the airline hose straight, insert and feed the fiber optic cable through the hose, leaving 12“ extra at each end (See Figure 3.4.1a).
   CAUTION: Maintain the largest possible radius within the enclosure. Bends should never exceed 90°; sharp bends or kinks will reduce the amount of signal passed.

3.4.2 Connect the Fiber to Display Enclosure

1. Insert the fiber through the brass fitting and into the enclosure, leaving an extra 6 – 8 inches of fiber coiled inside.
2. Position the airline hose so it abuts the brass fitting. (See Figure 3.4.2a)

3.4.3 Plug Fiber to the Receiver Connector

1. Flip the lid over to expose the back side.
2. Loosen the compression nut on the black optic receiver.
3. Ensure the end of the fiber is clean. Carefully insert the fiber into the black optic receiver until it sits flush against the optic lens.
4. Tighten the compression nut securely. (See Figure 3.4.4a)

3.4.4 Connect Fiber Optic Cable to Sender Bar Head

1. Use the supplied 45°, ¼” brass fitting.
2. Remove the lid from the sender bar head enclosure
3. Insert the fiber leaving 6 – 8” extra fiber inside the head of the bar. (Coil around inside the head once)
4. Loosen the compression nut (lefty-loosy, righty- tighty) on the white optic transmitter.
5. Ensure the end of the fiber is clean.
6. Gently, plug the fiber into white optic transmitter until seated flush against the optic lens.
7. Tighten the compression fitting. (See Figure 3.4.4a)

3.4.5 Install Airline on the Truck

1. Route the 1/4” airline from the sender bar head to the display. Avoid bends tighter than 90° and do not kink. (See Figure 3.4.5a) Airline can be routed either to the side of the tank to the display (Option 1), or to the back of the tank, down and then to the display (Option 2).
2. Ziptie the airline to the tank truck.

3.5 Program the Display

1. Refer to the 817-USB Truck Gauge Programmer Manual for programming instructions.

3.5.6 Verification of Bar Operation

1.  With the Opto pointing upward, place a magnet against both the head plate and the tube. (See Figure 3.5.6a)
2. Move the float on the bar up and down to ensure proper functioning. (See Figure 3.5.6b)
3. Correct operation is confirmed when there is engagement every 1/3 of an inch for 810-X, or 1/4 of an inch for 810-TX, on the 817-USB Truck Gauge Programmer. (See Figure 3.5.6c)

MAINTENANCE AND SERVICE INFORMATION

4.1 O-Ring
The 808-P2 relies on an O-ring to keep water out of the enclosure. To ensure long term reliability of the display, this O-ring must be kept lubricated with a silicone based grease. Check the display regularly and apply grease as needed. 4.2 Brass Fitting
The brass fitting should only be screwed into the display housing until it is flush with the interior surface. This ensures that any water that enters the display housing can drain effectively. 4.3 Cleaning Display
Never spray directly at the display with a pressure washer.
Cover the display if the tank is being cleaned with water pressure.
4.4 1/4” Airline
Refer to (See Figure 3.4.1a) to learn about installing a vent to help keep water out of the display.

TROUBLESHOOTING GUIDE

5.1 Diagnostic Flowchart
Refer to a separate document called “808-P2 troubleshooting flow chart”. The flowchart can be used to perform basic troubleshooting on the SeeLeveL gauge system. Some steps may require the use of an 817-USB truck gauge programmer. More advanced testing is also covered in the 817-USB documentation.

5.2 FAQs
5.2.1 Why does my display read “No L”?
= no Light condition. The display is working, but either the fiber is unable to send the signal from the bar or the bar is no longer sending the signal through the fiber. 5.2.2 Why does my display read “bL” and then a number?
= bad Light condition. It means the display is not working properly or that it is not getting a good signal from the bar. Remove the fiber from the display. If the display continues reading BL and a number, then the display needs to be replaced. If it goes to or , then start from one end and cut a ¼” from each end of the fiber to eliminate dirty or damaged fiber ends. Try blowing out the opto with some super duster or filtered shop air to see if it solves the problem. 5.2.3 Why does my display read “Sun”?
= Sun. This message could mean the display is not working properly or that the fiber optic receiver is getting too much light.
Cut a ¼” from the end of the fiber that is plugged into the display.
If the display starts working, then the problem is solved. If not, then the display could be the issue and needs to be replaced. Can also be caused by constant light from bar=bad bar or fiber is cut allowing actual Sun Light into the fiber line.

5.2.4 Why is my display blank?
This could simply be a blank spot in the programming and the offset needs to be adjusted. An easy way to find out is by unplugging the fiber from the display. If the display shows or when the fiber is unplugged, then it means the display is working correctly and the offset needs to be adjusted. If it stays blank, then the display is bad and needs to be replaced. 5.2.5 Why does the reading jump around when the tank is being filled?
This could be an issue with the calibration chart that was programmed into the display. If the display was reading correctly and this is a new issue, then it is possibly a bar issue. Contact service for information.
5.2.6 Why does my display seem to be stuck on a number?
Water damage can cause the display to get stuck and not show a correct reading. Could also be a corrupt bar sending bad data. Water damage inside the head or endcap leaking fluid into the circuit
