Important information
Neither the design of the device nor any technical safety aspects may be modified without
the express permission of Hottinger Baldwin Messtechnik GmbH. Any modification excludes Hottinger Baldwin Messtechnik GmbH from any and all liability for any damage resulting therefrom.
It is strictly forbidden to carry out any repairs and soldering work on the motherboards or to
replace any components. Repairs may only be carried out by persons authorized thereto
by Hottinger Baldwin Messtechnik GmbH.
All the factory defaults are stored safe from power failure at the factory, not in the measuring amplifier where they can be deleted or overwritten. They can be reset at any time by
using the command TDD0. For more information, see aed_help_e, AD103C; “Description
of the basic commands”.
The production number is set at the factory and cannot be changed.
The transducer connection must always be assigned.
It is essential for a transducer or a bridge model to be connected up for operation.

Safety instructions
There are not normally any hazards associated with the product, provided the notes and
instructions for project planning, assembly, appropriate operation and maintenance are
observed.
Each time, before starting up the modules, you must first run a project planning and risk
analysis that takes into account all the safety aspects of automation technology. This
particularly concerns personal and machine protection.
It is essential to comply with the safety and accident prevention regulations applicable to
each individual case.
Installation and start-up must only be carried out by suitably qualified personnel.
Do not allow the equipment to become dirty or damp.
5
During installation and when connecting the cables, take action to prevent electrostatic
discharge as this may damage the electronics.
The required power supply is an extra-low voltage with safe disconnection from the
mains.
When connecting additional devices, comply with the local safety requirements.
All the interconnecting cables must be shielded cables. The screen must be connected
extensively to ground on both sides.
The power supply and digital I/O connection cables only need to be shielded if the cables are longer than 30 m (32.81 yd) or are routed outside closed buildings
(EN 61326-1).
The CE mark enables the manufacturer to guarantee that the product complies with the
requirements of the relevant EC directives (the declaration of conformity is available at
http://www.hbm.com/HBMdoc).
In accordance with national and local environmental protection and material recovery
and recycling regulations, old devices that can no longer be used must be disposed of
separately and not with normal household garbage.
If you need more information about waste disposal, please contact your local authorities
or the dealer from whom you purchased the product.

1 Introduction and appropriate use
AED9101C digital transducer electronics are part of the AED component family that digitally
conditions signals from mechanical measurement sensors and networks them with bus capability. These include digital amplifier motherboards, basic devices with serial interfaces
and intelligent sensors with integrated signal processing. The purpose of these components
is to directly digitize and condition the measurement signals at the transducer location. Using
digital transducer electronics, you can connect SG1)transducers in a full-bridge circuit directly to a computer or a PC. This enables you to configure complete measurement chains
quickly and with little extra work.
Basic device AED9101C can contain the AD103C amplifier board. It provides mechanical
protection, shields the amplifier board (EMC protection) and allows you to select the serial
interfaces RS422 (factory default), RS485 or RS232.
The AD103C amplifier mother board is not included in the scope of supply of the basic device and must be ordered separately.
Introduction and appropriate use
The AD101B amplifier is only required for replacement and will not be considered when new
AED basic devices are ordered.
The PC software AED PANEL 32 is available to facilitate parameter settings, to display dynamic measurement signals and for comprehensive analysis of the dynamic system.
The HBM display unit DWS2103 can be connected to all AED basic devices.
All basic devices of the AED family can be connected with the digital display unit DWS2103.
This unit supports all implemented functions of the AED.
All commands are described in the help file aed_help_e.
The abbreviation AED is also used for transducer electronics in the following text.

2 Mechanical construction
The basic device extends the functionality of the AD amplifier boards and provides:
mechanical protection (IP65)
the power supply for the amplifier motherboard and transducer excitation
total transducer bridge resistance 40…4000
a choice of serial interfaces RS422, RS485, RS232
EMC-tested
Diagnostic bus
(The AED9101A basic device can be replaced by the AED9101C basic device)

The amplifier motherboard is designed as a plug-in board that can be plugged into the carrier
board of the basic device via a 25-pin D-connector. The basic device contains terminals for
the transducer, power pack and interface connections, slide switches for interface selection
and the voltage stabilizer. The connection cables exit the casing via PG glands on the side.

3 Electrical connections
A connection diagram is attached inside the lid of the AED9101C basic device.
When making the connections, please ensure that the wires of the cable do not protrude
beyond the connection terminals (risk that loops may form). Please make sure that the
cable shielding is properly connected to the PG gland.
If it should be necessary, a separate cable can be used to establish potential equalization
between the transducer and the AED and between the AED and the Master control unit
(grounding concept). The cable shielding must not be used for this potential equalization.
Electrical connections
3.1 Transducer connection
The transducer connection must always be assigned (connect the transducer).
AED9101C with AD103C
You can connect SG transducers in a full-bridge circuit with a total bridge resistance of
RB= 40...4000 . With a transducer resistance of > 1000 , increased noise (measurement
ripple) must be taken into account. The bridges are supplied with power in the AED9101C
basic device (5 VDC).
