advanced multi-function indicator
Description
General
This specification describes the
E1205 advanced multi-function
weight indicator, capable of
stand-alone operation, or of
integration into a larger system
via serial, FieldBus and Ethernet
interfaces.
It is a microprocessor-based
industrial weighing system with up
to 100,000 displayed increments
for analysing, displaying, storing
and transmitting gross and net
weight information.
E1205
E1205
Up to 12 load cells to be
connected with the indicator
(16 with second scale).
Analogue load cells or Avery
Weigh-Tronix digital load cells
may be used.
This indicator can display weight
data from two scales
simultaneously. Both scales are
active and are independently
weighing at all times.
The E1205 can be matched to
almost any load cell system to
achieve optimum accuracy,
stability and repeatability.
The indicator can control its
surrounding process using fully
configurable I/O.
Alternatively, control can be
executed from a central system
using an extensive range of
available interfaces.
Configurable Features
The E1205 features a dual
purpose alpha-numeric keyboard
which allows any of the following
functions to be configured during
commissioning:
● Sensitivity to weight signal
● Scale capacity
● Number of divisions and
increment size
● Weighing Unit
● Zero/back balance
● Decimal marker type - point or
comma
● Position of decimal marker
● Calibration site gravity factor
● Customer site gravity factor
● Filtering using FIR or
Harmonizer™ filtering systems
● Ten points for linearity
correction to ensure maximum
accuracy
● Tare availability and manner of
operation
● Time and date (two or four
digit year, battery backed)
● User-definable serial output
strings
● Subtotal and grand total
information
● Scale ID number
● Alarm index operation
● Recipe/filling I/O
configuration

E1205
Avery Weigh-Tronix Technical Specification
All these characteristics are
stored in non-volatile memory so
that once the ideal parameters for
any given weighing system are
established they can be retained
with certainty for the future.
Once the scale is set up as
required, a calibration report can
be printed showing weighing
details (useful for the installation
engineer). This allows the state of
the system to be monitored.
Up to 300 product look ups
(PLUs) are available for instant
recall of previously programmed
product information.

Dynamic Filter
Applied after the FIR filter.
Set the filter window size in
divisions (0 - 99). A high value
will have a large damping effect
on the weight display.
This significantly slows the scale
response to a legitimate change
in weight.
Harmonizer™ Digital Filter
Three programmable parameters:
Samples to Average - sets
number of A-D conversions which
will be averaged to give a weight
reading.
IIR Filter - sets how much
damping the Harmonizer™
applies to the weight reading.
Typically between 1 (low) - 8
(higher).

Harmonizer™ will not attempt to
filter out as noise.

Tares
Three types of tares are available.
Each is 100% subtractive.
Note: Interlocks between the tare
types are configurable at time of
commissioning.
Type A - Push-Button (Semi
Auto) Tare
Push-button operated, semiautomatic, with selectable
negative weight display.
Cumulative taring is possible.
Initialisation and Operation
When the item to tare on is
applied, press the ‘Tare’ pushbutton.
Indication
‘Net’ annunciator is illuminated.
Type B – Keyboard (Pre-set)
Tare
Keyboard-entered tare operated
with negative weight display.
Initialisation & Operation
Enter pre-set tare value using the
0-9 keypad and press ‘Tare’ push
button. Multiple pre-set tares are
possible.
Indication
‘Net’ annunciator is illuminated
together with pre-set tare
annunciator (PT).
Type C - Stored Tare
Stored tare operated with
negative weight display allowing
40 separate stored tares. Will be
retained when power is off.
Initialisation & Operation
Press ‘pre-set tare’ push button
followed by the stored number ‘1’
to ‘40’ followed by ‘enter’ key.
When two platforms are used, 20
stored tares are available for each
platform.
Indication
‘Net’ icon is illuminated together
with preset tare icon (PT).
Trips
The indicator has three internal
trips as standard, and can support
up to 16 external trips via external
Trips Interface Units
(see accessories).
All trips (both internal and
external) are rated at 240 V 10 A.
Internal inputs are rated at TTL
levels.
Two modes have independent
control of the trip outputs, Alarm
and Recipe. Alarm mode
operates continuously.
Recipe mode is dependant on the
Recipe / Filling application being
configured and in operation.
Alarm Mode
Alarm mode has 10 independent
configurable indexes, and cannot
be turned off. Each index can be
programmed to operate any or all
outputs based on a given target:
● None - index inactive
● Target Weight
● Status of indicator, e.g. weight
steady, checkweigh accept
● Input (single or specific
pattern)
● Output (single or specific
pattern)
● Time
Recipe /Filling Mode
Recipe/Filling mode has 20
configurable sequential steps,
and is active only in Recipe/
Filling mode. Each recipe
(maximum 100) can be
configured independently to the
others. Each index can be
programmed to operate any or all
outputs based on a given target:
● None – index inactive
● Target Weight (includes
tolerance, compensation and
dosing parameters)
● Status of indicator, e.g. weight
steady, checkweigh accept
● Input (single or specific
pattern)
● Output (single or specific
pattern)
● Time
Other variables that can be
configured in Recipe / Filling
mode are:
● Outputs at start of step
● Outputs at end of step
● Target action (e.g. print)
● PLU to accumulate totals data
All configuration information is
retained when power is off.

time clock which allows the user
to display and print the time and
date. This clock is battery-backed
and will remain functional in the
absence of mains power.
