1 Overview
The Weighlog Ex is a CAN-based system that measures, displays and records the net weight lifted, based on
sensing the lift system hydraulic pressure.
Main components
Two pressure sensors [1], [2] are installed into the hydraulic lift system, with possibly two more [3], [4] installed on
machines fitted with accumulator-assistor cylinders. The pressure signals are captured, filtered and corrected by measuring
the angle of the main boom using an inclinometer [5]. Slope corrections are made from another inclinometer [6] on the
chassis. Dipper arm position is measured from a mechanical angle sensor [7] mounted on the boom to dipper arm pivot.
As an added option, oil temperature compensation is provided by a clamp-on sensor [8]. An ultrasonic sensor [9] is
used to provide reliable and precise bucket compensation.
All signals are processed in a separate Weighing Module [10], and the resultant weight calculation is sent via
CANBus to the head unit [11]. Load and store information is saved in the head unit where it can be distributed to an
in-cab printer, modem or internal SD card.
SQL database capability with up to 8 reference fields, provides virtually unlimited inputs of products, customers,
trucks, hauliers, locations, destinations, mix blends and notes.
Video input for switching the head unit into reversing camera mode, removes the need for an additional display
monitor.

Weighing modes
When used dynamically, the pressures are captured through a set weighing zone.
The system may also be used in static weighing mode. The boom can either be lifted to a set weighing position
where the pressure is captured, or measured constantly in a “live” mode at any required boom height.
Both dynamic and static weighing positions are adjustable by the operator to suit any job required, which will
enable the machine to be used at its most efficient output.

Chassis Angle Display
The instrument can be configured via the ‘Home Screen Functions Setup’ screen in
the ‘Calibration’ menu, to display the Chassis angle (Uphill / Downhill) in place of an
Information Store.
The Status Bar
Touchscreen
The instrument has a 5-wire resistive touch screen. 5-wire technology offers superior life and reliability without
requiring re-calibration. However, it consists of a polyester film outer layer that must be treated with respect,
compared to a non-touch display with toughened instrument glass. Therefore, pleas observe the following,
DO NOT use a sharp-pointed object - the screen will be damaged beyond repair!
Do NOT wipe or otherwise attempt to clean using any kind of solvent cleaner!.
Do NOT wipe using a dirty cloth or gloves. Use only computer screen wipes designed for the purpose!.
You may use a blunt, smooth-ended plastic object (e.g. a pen body / cap) as a stylus, if found necessary!

3 The Loading Cycle
3.1 Machine Requirements
The accuracy of the system depends to some extent on the following :
1. Operating Temperature : Always allow the machine and the hydraulics to warm up to the normal operating
temperature before commencing weighing.
2. Weighing on level ground : The chassis angle sensor provides automatic correction if weighing on a slope.
3. Boom lift and vehicle movement : Anti-bounce compensation and filtering help to maximise weighing accuracy.
Best results are obtained when weighing while the vehicle is stationary.
4. Maintenance : Keep your machine maintained in good condition. Things like excessively worn bushings, pivot pins
etc, as well as lack of lubrication to these areas can have an adverse effect on weighing accuracy. After any major
servicing particularly if you have replaced worn components or carried out welding repairs, you should re-calibrate
the weighing system. If the hydraulic system has been drained and re-filled, you should also check for any air that
may have become trapped at the pressure sensor(s).
3.2 Lifting Procedure
The correct lifting procedure is especially important for dynamic weighing. The best procedure is as follows,
1. Having picked up the load, angle the attachment to the position for weighing. The options are either,
(i) Keep attachment angle fixed relative with ground (e.g. a bucket or
winging attachment).
(ii) Keep attachment angle fixed relative with boom (e.g. a bucket
attachment).
(iii) Keep attachment angle fixed relative with dipper (e.g. a fixed grab
attachment).
The attachment position is set as part of the bucket calibration procedure when the system was first calibrated. It is
important to weigh with the attachment at the correct angle, since it is a very important factor in achieving consistent
and accurate weighing.
Attachment weighing position options
“With ground” “With boom” “With dipper”
Weighing will be inhibited unless the attachment is at the correct position.
2. Lift smoothly without bouncing or jerking, at the correct lift speed.
In Dynamic Weighing mode, the system has lift speed compensation and will alert the operator in the event the lift
speed is too fast or too slow.

3.4 “Last Bucket” Weighing
When in either Dynamic or Static weighing mode, if the weight exceeds the target required, the weight display turns
RED. Regardless if “Auto Entry” ( ) is enabled, the system does not automatically enter the “last bucket”
weight. You have to manually enter the weight using the Remote Enter button (if fitted), or the key.
There are several methods for "Last Bucket" weighing.
3.4.1 "Undo last Lift" (Dynamic / Static Weighing Mode)
If the last added lift is too much, the operator may wish to simply cancel the last lift, tip off some material back onto
the pile, and weigh again.
1. Press the key, and select “Undo Last Lift”. This will subtract the last lift from the weighing screen and the
Store totals.
2. Tip out some material and then lift again through the weighing zone, until the required amount has been weighed
and added again to the total.
NOTE: If setup via the ‘Home Screen Functions Setup’ page in the calibration menu, a ‘Clear Last Entry’ function
( ) replaces the ‘Pause’ function ( ) on the weighing screen.
This then allows you to immediately remove the last lift from the total with a single key touch.
3.4.2 "Reweigh the Remainder" (Dynamic / Static Weighing Mode)
In some cases where the truck also has an on-board weighing system, the operator may tip a partial amount off the
“last bucket” load to “top-off” the truckload, as directed by the truck driver.
The “re-weigh” function enables the weight of the material remaining in the bucket to be re-weighed and subtracted
from the truck total, ensuring the recorded total matches the actual weight loaded into the truck.
1. Press the key, and select “Reweigh the Remainder”.
2. Lift again through the weighing zone. The weight of material remaining in the bucket is subtracted from the truck
total.
3.4.3 Live Static "Tip-off" Mode
"Undo last Lift" and "Reweigh the Remainder" “last bucket” weighing are trial and error methods. To assist in
measuring the amount required for the last dynamic weighing, the "Live Static Tip Off" feature may be used.
1. Lift up to any suitable height, and then press the button. The “live” calculated weight, and button icon are
then shown in GREEN. The weight shown is now live.
2. Allow the live display to settle down before checking the true weight. "Live Static Tip Off" can be configured to
operate in either of two ways,
3(a) Tip off material back onto the pile ("Pile Tip Off - Manual Add On" configuration). The instrument displays the weight
remaining in the bucket as you tip the surplus material back onto the pile.
3(b) Tip off material into the truck ("Truck Tip off" configuration). The instrument displays the weight tipped off the bucket
into the truck (to match the 'weight left to load' display).
4. To enter the 'Live Tip-off' weight, press the Remote Enter button (if fitted), or the key.
NOTE 1: "Live Static Tip-off Mode" must be configured to “Pile Tip Off (Manual Add On”), otherwise weight entry is not
possible whilst remaining in Live static mode. "Live Static Tip-off Mode" is configured from the 'Sensor Sampling and
Setup' screen ('Factory' calibration menu).
