- Page 1 ED2-Series SkidWeigh System Automatic Check Weighing for Loading Shovels, Skid Steers, Loaders, Telehandlers and Recycling Material Handling Vehicles Ver.120706-22-SD4 ED2-L Series showing the load weight in t (tones)
- Page 2 The ED2-SSL, ED2-CC and ED2-L Series SkidWeigh systems are an automatic heavy duty loader /forklift checks weighing /overload warning system used to verify load weights on the move. This is not a “Legal for Trade” scale, but an economical on-board check weighing system that will allow your loader operator to increase vehicle utilization, increase productivity, provide operator safety and display the load weights readout within +/-0.5% to +/-1% of the vehicle’s lifting capacity.
- Page 3 Mounting Location for Digital Indicator The compact design and light weight the ED2 Series digital indicator can easily be mounted within the operator’s compartment. Select a suitable location and using the mounting bracket with the anti-vibration mount install the digital indicator on the vehicle’s dashboard preferably on the right hand side. A bracket can be bolted onto a lock striker plate, window frame or turret support.

2. The pressure transducer must be installed in the hydraulic line between the lift control valve and the lift cylinder(s). If possible locate a hydraulic fitting that can be removed to allow drilling and tapping. Failing this a hydraulic adaptor can be fitted. Connect appropriate fitting and hose to allow pressure transducer to be mounted in a safe location. - Page 5 Digital Indicator Calibration / Setup Two Keys Description Upper Right Key Labeled “M” (Calibration / MODE key) Lower Right Key Labeled “⇑ ⇑ ⇑ ⇑ ” (0 – 9 numerical increments input key) MODE Five Digits Load Weight Readout Display Digit 5 Digit 4 Digit3...

(With engine at the idle speed, activate lift control valve fully, do not stop until you get weight readout).
- Page 13 If another weighing cycle is not to be initiated and the vehicle is in motion or the forks are lifted during normal operation, the hydraulic pressure “spikes” will be introduced and some random readout value on the digital display will be shown. The value displayed might be 0, 10, 20, 25, etc. This readout value does not represent the load weight, but is only a readout value due to the vehicle motion and the system automatic weight cycle.

- Page 23 ED2 Series SkidWeigh User’s Manual (Vehicle Operator Copy) The ED2 Series SkidWeigh is fully automatic lift truck / loader check weighing /overload warning system. This is not a “Legal for Trade” weighing scale, but an economical onboard check weighing system that will allow your lift truck / loader operator to determine the load weight readout within +/- 0.5% to +/- 1% of the vehicle lifting capacity.
- Page 24 Dynamic Weighing Method To obtain a load weight readout the lift truck operator is to lower the loaded bucket / forks to the ground, wait until the indicator MODE shows the number then the load is being lifted without any interruption until load weigh is shown on the indicator.
- Page 25 Right Button : Reset and print function of accumulative load weights Every time the indicator shows the load weight and the right button is pressed, the current load weight or current total weight in the counter will be reset. In the case of the system equipped with onboard printer, the weight ticket will be printed.
