1.0  INTRODUCTION 
 
  The AE 402 indicator provides the user with the ele ctronics necessary to 
build an accurate, fast, versatile weighing system.    
 
  Functions  are,  weighing,  check  weighing,  parts  coun ting,  animal 
weighing and percent weighing.   
 
   The  system  includes  automatic  zero  tracking,  audibl e  alarm  for  check-
weighing,  semi-automatic  tare  and  an  accumulation  f acility  that  allows 
the individual weights or counts to be stored and t he total recalled. 
 
  The  scales  have  a  bi-directional  RS-232  interface  f or  communicating 
with a PC or printer. 
 
  RS-232  outputs  include  Real  time  Clock,  English,  Ge rman,  French  or 
Spanish language text and data required for GLP rep orts. 
 
  The indicator can be used with 1- to 4 load cell pl atforms. 
 
  Internal  rechargeable  battery  and  IP-65  rated  enclo sure  allow  for  a 
fully portable and rigged  weighing system.

3.1  LOCATING
 THE SCALES 
 
   
 
 
 
 
 
 
 
   The  scales  should  not  be  placed  in  a  location  that  
will reduce the accuracy.  
 
  Avoid  extremes  of  temperature.  Do  not  place  in 
direct sunlight or near air conditioning vents. 
 
 
   Avoid  unsuitable  tables.  The  table  or  floor  must  be  
rigid and not vibrate.  
   
   Avoid  unstable  power  sources.  Do  not  use  near  
large users of electricity such as welding equipmen t 
or large motors. 
   
   Do not place near vibrating machinery. 
 
 
   Avoid  air  movement  such  as  from  fans  or  opening  
doors.  Do  not  place  near  open  windows  or  air- 
conditioning vents. 
 
 
   Keep  the  scales  clean.  Do  not  stack  material  on  the  
scales when they are not in use.

3.3  SETTING UP THE SCALES 
     Attach the power supply module to the connector  on  the side of the indicator. 
Press  the  [On/Off]  key.  The  software  revision  number  will  be  displaye d 
followed by a self-test showing all digits before t he zero is displayed along with 
the unit of weight that was selected last.

3.4.2 CONNECTION OF RS-232    
RS-232 serial interface is a plug as figure 2 shows : 
 
       
1: Pin GND,   Signal Ground 2: Pin RXD,    Received Data 
          3: Pin TXD,    Transmitted Data          
 
 
As viewed from the back of the indicator 
  
See section 9 for details of the RS-232 Interface.    
3.4.3 CONNECTION OF RELAY DRIVERS     The  output  to  drive  external  relays  is  on  the  circu it  board  inside  the  enclosure.  To 
gain access you must remove the 6 screws securing t he front to the rear of the case.  
Pass the wires for the relays through the grommet o n the rear panel.   The wires will 
connect to the PCB using the terminal strip P1.

[Func/C]  
  Selects the Functions of the scale. If the scale is
 weighing, it 
will select parts counting. If it is not in weighin g mode, it will 
return the user to weighing.   
 
A secondary function (C) is to act as a clear key w hen setting 
values for Parameters. 
 
[Print/M+/Esc]   
  Sends  the  results  to  a  PC  or  a  Printer  using  the  RS
-232 
interface.  It  also  adds  the  value  to  the  accumulati on 
memory if the accumulation function is not automati c.  
 
A secondary  function  (ESC) is  to  return  to normal  operation 
when the scale is in a Parameter setting mode. 
 
[O/I]   
  To switch on and switch off the indicator.  
The AE402 will store the weighing unit in use and t
he check 
weighing values currently in memory when power is o ff.  
  
5.0  DISPLAYS 
  
The LCD display will show a value and a unit to the right of the digits.  
In  addition  the  LED’s  above  the  display  will  show  w hen  a  weight  is  below  or  above 
check-weighing limits. 
  
 
  
Other symbols will show when a weight has been tare d (NET) the scale is at zero and 
stable, if a value has been stored in memory or whe n the animal weighing function 
has been enabled.  A battery symbols will show the  state of charge of the internal 
battery.
