1.0 INTRODUCTION
This Service Manual will guide you through the normal service and calibration procedures
necessary to maintain the indicator. Please read this Manual thoroughly before performing
any service. This manual should be used in conjunction with the User operation manual.
2.0 SAFETY
HIGH VOLTAGE
The indicator has high voltage inside. This high voltage can be lethal.
Only use the indicator, in mains sockets with safe and reliable earthing.
When service the indicator, power must be disconnected, it is essential to separate display
plug from external power.

© Adam Equipment Company 2019
3.0 PANEL INTERFACES
The indicator has connectors for the power, data interface, load cell and relay (option).
3.1 POWER
Ensure your indicator is compatible with the mains power supply in your area. Look for the
model label on your indicator and check the voltage and frequency your indicator is
designed to operate, if these values aren’t the same, as the power supply in your area, it
can be dangerous to connect the indicator to the mains and it will probably damage the
indicator.
3.2 DATA INTERFACES
The indicator has data interfaces for a variety of applications.
The RS232 interface used in this indicator, is a general-purpose serial interface for two-
way communications with the indicator.
See the User manual sections 7.2 and 9.0 for more details.
3.3 LOAD CELL INTERFACES
The indicator has several load cell interface options, to allow for the user to connect it to a
wide variety of weighing platforms.
Due to approval or some special application, the user may need to connect the load cell
cable directly to the PCB board.
See the User manual sections 3.4.1 and 11 for more details.
3.4 RELAY INTERFACES
The indicator has an optional relay interface. If you need this option, please contact Adam
Equipment or your dealer.
See the User manual section 10.0 for more details.

4.0 INDICATOR MENUS
The AE 403 has several submenus for setting the operation of the indicator and the
communications. In addition to the Supervisor menu, which can be used to configure the
indicator to the user needs, there is a Dealer menu that allows for a limited settings access,
in this menu you can calibrate the indicator, observe the ADC counts from the load cell
and change the gravity correction. There is also a User menu, that allows for a calibration
of the indicator.

All the operations can be performed by the keypad. See user manual section 4.0 for
specific keypad function.
4.1 SUPERVISOR MENUS
 Press and hold the[ ] key about 2 seconds to turn on the indicator, and wait for
the scale to perform the start-up self-test.
 During the self-test procedure, press the [ ] key to enter the supervisor menu,
when “” is displayed, and enter the supervisor password.
 To enter the password, use the directional buttons [] to scroll through numbers 1-
9. Use the [] directional key to move to the next digit.
 Entering the correct password [1946] will take you to the supervisor menu. The
displays will show the first parameter “”.
 Press the [ ] key to enter a parameter, the display will guide you through the
parameter selected and the options available.
 To exit a parameter, press the [Esc].
 Press [] or [] key to select other parameters.
 Press the [Esc] key again to return to weighing.

The display will show the available parameters:
4.1.1 “” Display the A/D counts
Press the [ ] key to enter this parameter. This parameter allows you to view the A/D
counts from the internal A/D converter.
This can be an aid to service.
The weight ADC counts are normally stable within a few counts if the load cell is
functioning correctly, the environment is stable, and the temperature is stable. The range
of the ADC counts will depend upon the load cell used and if the bracket is in place or not.
