1. Overview
The Weighlog 200 is intended for se on ind strial and agric lt ral loading
shovels, fore-end loaders, back-hoe loaders, (loader side only), tipping
trailers and tipping tr cks.
It meas res, displays and records the net weight lifted, normally based on
sensing the lift system hydra lic press re. Press re sensing is problematic
on certain types of eq ipment d e to the design of the hydra lic system. In
these instances strain sensing technology may be sed instead. The
Weighlog 200 also has lift speed compensation to improve acc racy when
weighing dynamically.
The instr ment has an ill minated 4-digit LCD display, 5 front panel switches,
an external Load Enter B tton, and an internal a dible alarm. An external
a dible alarm is optional. The instr ment is normally powered on via the
ignition circ it and recalls the f nction selected when last sed.
There are 5 individ al display channels available. These can be calibrated for
p to 5 different loader attachments, different trailers or different
commodities. Each channel will display the net b cket weight lifted at any
time. If req ired the b cket weight can be added to the total for the channel
in se and will also be added to the TOTAL channel, which acc m lates
weight from all of the five channels.
The instr ment has a Load Alarm f nction. If the load exceeds a preset
fig re, an a dible alarm is triggered and the weight display will flash.
The instr ment can be config red to a tomatically print each b cket weight
entered, or individ al load total when the instr ment is zeroed for the next
load. Also, yo can at any time print o t the acc m lated total for channel 1
to 5, and the Grand Total (channel 6).
For each channel yo can :
• Adj st the Weight Calibration Factor
• Set either Static or Dynamic Weighing Mode.
• Set the Zero Weight.
• Display and add the b cket weight to the s b-total.
• Receive a dible alarm confirmation of the zero and load entering.
• Print the last b cket weight a tomatically
• Print an acc m lated total
• Reset the acc m lated total (and a tomatically print a s mmary)
• Compensation for variable lift speed (dynamic weighing only)

Programming Modes
There are 3 programming modes with vario s calibration factors and defa lt
settings. Many of these settings are made on installation and do not normally
need to be changed nless the instr ment is moved on to a different loader.
The operator does not normally need to access the programming modes.
CAL Mode 1 is for weight calibration. The instr ment is calibrated
independently for each channel 1 to 5 (e.g. each channel can be dedicated
to s it a partic lar attachment or commodity). Channel 6 is sed to
programme the Overload Alarm.
CAL Mode 2 covers Speed Compensation Factors, Static weight reado t,
Man al weighing ( sing the REF b tton), Time, Date, and Units selection.
CAL Mode 3 is for Printer Setup.
NOTE: With careful operation, system accuracy can be as good as ±1% of lift
capacity although ± 2% is more common in practice.
Weighlog readings are not suitable as a legal basis for the sale of goods.

2.1 Display Units
The instr ment can be set to display nits as tons (USA)/ tonnes, kgs or lbs.
When set to the "kgs" or ‘lbs’ reado t option, the display will read p to
‘9990’ ro nded to the nearest 10 nits. Above this threshold (e.g. when
displaying any of the totals) the display will alternate between "lbs x 1000"
and any remainder. Therefore, the instr ment can display p to 999,990 lbs
The table below gives examples of the reado t.

2.2 Machine requirements
The Weighlog translates press re (or strain) to weight by means of a
calibration factor programmed into the instr ment. The acc racy of the
system depends to some extent on the following :
1. Operating emperature : Always allow the machine and the hydra lics to
warm p to the normal operating temperat re before commencing weighing.
2. Weighing on level ground : Avoid weighing when on a slope or a side
slope. Wherever possible weigh on a level area.
3. Vehicle movement : Best res lts are obtained when weighing while the
vehicle is stationary. It is important that the load does not bo nce or jerk as it
is lifted.

OVERVIEW

4. Maintenance : Keep yo r machine maintained in good condition. Things like
excessively worn b shings, pivot pins and slideways, as well as lack of
l brication to these areas can have an adverse effect on weighing acc racy.
NOTE: 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 which may have become trapped at the pressure sensor.
2.3 Lifting procedure
The correct lifting proced re is especially important for dynamic weighing.
The load sho ld be lifted smoothly and consistently thro gh the weighing
position. The best proced re is as follows :
1. Having picked p the load, crowd (roll) the b cket right back as far as it will
go.
2. P ll the lift lever right back with the engine at idle.
3. Increase engine revs to the "weighing speed" and lift smoothly witho t
bo ncing or jerking. Ens re that yo lift at the weighing speed as yo pass
thro gh the reference position (dynamic weighing).
If when lifting the bucket in dynamic weighing mode, the instrument
displays ‘FASt’ or ‘Slo’ and beeps 3 times, then lower and lift again at an
appropriate speed.
his also applies when checking the zero weight (section 3.3, 3.4).

3. Before Weighing
3.1 Select Channel
Ens re that the correct channel is selected
for the attachment / commodity / trailer to
be weighed.
Simply press the b tton to cycle
thro gh the channels.
3.2 Select the Weighing Mode
In the normal operating mode, yo cannot
switch between Static and Dynamic
weighing mode on an individ al channel.
Separate channels are set p for either
Static weighing or Dynamic weighing, as
part of the weight calibration ro tine
(6.2.4). Yo then select the appropriate
channel for the weighing mode yo wish
to se.
Checking the Weighing Mode.
1. HOLD the b tton and power-on the
instr ment (Fig. 4). The display will show
“dYn” for dynamic weighing mode or
“StAt” for static weighing mode, for
channel 1.
2. Press the b tton to cycle thro gh the
other channels.

3.3 Check Zero Weight
Yo sho ld check the zero weight
reg larly as part of the daily operating
ro tine. ALWAYS check zero weight if the
machine has been left idle for some time
and has cooled down.
The lifting proced re is different for
Dynamic and Static weighing modes. Note
the weighing mode set on the channel yo
have selected and follow the appropriate
proced re below.
1. Ens re that the b cket is completely
empty. Crowd (roll) the b cket right back
as far as it will go.
2.a Dynamic weighing mode : Lift the b cket
thro gh the reference position. Two beeps
will be heard. The display will show a
val e.
2.b Static weighing mode : Lift the b cket p
to the reference position and stop. A
single beep will be heard. If yo lift too
high, the display will show 4 dashes (fig.
6). If so, lower the b cket back down to
the reference position.
3. If the display reads within ±0.02t, or 20
kgs, or 40lbs (fig. 7 depending on the
display nits selected, this is within the
repeatability of the Weighlog system and
can be accepted witho t zeroing the
weight. Simply contin e loading as
normal.
4. If the display reads more than ±0.02t, or
20 kgs, or 40lbs (fig. 8), then yo sho ld
zero the weight (see 3.4).
