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 Normal = +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.
