LoadRunner connectors have keyways and are gendered and thumb tightened for ease of use. System kits are supplied with fully molded connectors. Rewirable plugs are available for replacements or repairs. The RS-232 connector is industry standard. This manual also shows interchangeable rewirable plugs.

Figure 3-4. Connectors

RLWS cables and connectors are specially designed to provide maximum signal strength and reliability. Substitution of cabling other than RL WS supplied cabling may cause inconsistent and erratic readings. Care should be taken when routing cables to provide protection from sharp edges, drive-line rotation, exha ust pipe, or any o ther potential damage. Secure in place with cable ties to a snug fit. Locate the junction box mid-chassis at a suitable accessible position and fix firmly with screws supplied.

4.1 Printing & Print Tickets

Ensure the RS-232 option is set to PRINTER and a printer is connected with the cable supplied. The printer is powered through the RS-232 connector and uses a default baud rate of 9600. There are three print tickets available:

4.1.1 Truck Weights

Net, gross, time and date is printed

4.1.2 Load Mode

Press print in load mode.

Time & date together with individual and total bin collections from a site and truck information is printed. This mode can also be used with the additional keyboard to enter an account number for the site.

4.2.1 Operator Instructions

Load/Deliver Function

With the load/deliver function turned on, the driver has acce ss to the load/deliver and total screen. This function allows tracking of the print and accumulate transactions for a load (increase in weight) or delivery (decrease in weight).

The OB-350 is designed to only accumulate a positive value, either load or delivery.

1. To activate, while in the load/deliver screen, select the ON Site key. The function keys perform the following:

• Off – turns off load/deliver accumulation mode

• Print – accumulates displayed weight in total value, prints t

• Zero – allows the display to be zeroed.

Total Driver Display

With the load/deliver function on, the total display will continue to accumulate the weight value. To clear the total weight value, press the zero key.

Zeroing the total display will not affect the load/delivery accumulation window.

and clears the totals accumulation.

6.8 Inclinometer

On dump trucks and roll off applications, the LoadRunner system uses load pins and a hydraulic pressure transducer to determine a weight value. To achieve the best accuracy, calibrate the system at the same incline that will be used for determining the weight value, within ±1-2 degrees.

The inclinometer setup screen shows both and absolute angle (abs 0.0). For this application, use the level indicators that light up for every degree the body is raised.

The numeric value will indicate a negative value as the body is raise normal. The level to the right will light up one circle at a time.

The inclinometer function allows visual determinatio achieves to accurately weigh consistently.

8.1 Terms

The following abbreviations, phrases and terms used in this manual are widely used in the truck weighing industry. ALARM An alarm sounder or flashing beacon (where fitted) will activate when

alarm set point is reached.

BOGY Refers to a group of axles fixed close to each other, also known as dual or tri-axles. CHANNEL Is the Input Channel. DUAL Input channels 1 & 2 added together, the total weight of channel 1 & 2 will be

displayed. Most RLWS load cells can be connected together in parallel as the milli- volts signals are compatible. Load cells, oil & air pressure transducers and fifth wheel load cells have different millivolt outputs and cannot be connected into one junction box (with the exception of CANbus enabled sensors).

GROSS GVW or GMW (gross vehicle weight or gross mass weight) is the total truck

weight (NET + TARE).

HYS Hysteresis - gives the option to activate the alarm in a window range above 

and below the alarm set point (an alarm reset tolerance).

INPUT The input channel load cell groups are connected to the INPUT. LOAD Part load collected or delivered – press PRINT to print and zero the load,

weight collected is stored as an accumulation to NET & GROSS.

NET The payload weight in the truck body. ON SITE When Load is turned ON in options, on site allows logging onto site and

off site for weighing loads collected from a site with multiple bins (waste only).

OUTPUT No rmal = +12 VDC to power and alarm, Output invert = -12 vdc to deactivate 

(a packer plate).

PIN Personal Identification Number – password. PPCO Packer-plate cut-off, refuse trucks only. PUK Pin Unlock Code. SPAN The NET weight used to calibrate the scale. It is the difference between

the tare (curb or empty weight) and the gross weight.

SPLIT DUAL Separate input channels, i.e. front and rear transducer sets are connected. SPLIT SINGLE One input channel, all transducers connected into one junction box (in parallel). TARE Means the weight of the empty (no load) vehicle. TRIGGER This is a selectable time delay prior to alarm activation. TRANSDUCER Load cells, oil & air pressure sensors, fifth wheel load cells etc. TWIN Input channels 1 & 2 are displayed separately (e.g. the front and rear of a vehicle). 

Separate calibrations are required which require weighing the front and rear axle/s separately and entering the data.

ZERO Zero Functionality:

• No load zero, any minor discrepancies (+/-1100 lb) because the truck body has ‘normalized’, e.g. stresses and strains incumbent in the mechanical construction of the truck has weakened and dissipated.

• Driver zero allows the driver to zero the weight taken from a site to allow the next site’s printed ticket to show as a separate set of weighting transactions.

8.2 Troubleshooting

Note

8.2.1 Fusing

The OB-350 is fitted with a self-resetting thermal fuse. In the event of a fault or an electrical surge, the thermal fuse will activate and cut power. The fuse will reactivate after a few seconds, once the fault has been removed. Trip current is 300 mV or greater than 30 VDC.

Perform the following simple checks to

1. If the readings are incorrect, but consistency is high or low

2. If the weight values are erratic, check the power supply replace the indicator.

3. If the indicator is found to be defective, remove problem has not been isolated, continue with the troubleshoot procedures.

Recalibration at this stage could complicate the problem. However, once the problem has been identified and corrected, it would be advisable to refer again to Section 7.0 for calibration details.

8.2.2 Diagnostics

The diagnostic tool displays the electronic signals coming in from load cells, sensors or CANbus enabled devices. Values shown will vary according to tare weights, any load in the body of the vehicle and mechanical installation integrity. Look for consistency, positive values, and pairs of cells showing similar or dissimilar readings. Typical millivolts readings may range from 1 to 8 mV, (no load to full load).

8.2.3 Visual Checks

If no indicator defects can be found, the fault may be in the cables or lo ad cells. A v is ua l in sp ec ti on o f ca bl es f or damage or chafing, crushing. Make sure the cables connections are secure and thumb tightened. Make sure exposed connections are clean and dry.

and contact RLWS service for a replacement. If the

8.2.4 Load Cell checks

If the display still shows an erratic reading or unusual high reading, disconnect one load cell from the junction box and note its effect on the display. If the display shows a significant impediment, the load cell is probably at fault and will need replacing. If no significant improvement is noticed, reconnect the load cell and repeat the procedure for the remaining load cells.
