1 Safety instructions

Appropriate use

The device is to be used exclusively for measurement

tasks and directly related control tasks within the applica-

tion limits detailed in the specifications. Use for any pur-

pose other than the above is deemed to be non-desig-

nated use.

Any person instructed to carry out installation, commis-

sioning or operation of the device must have read and

understood the Operating Manual and in particular the

technical safety instructions.

In the interests of safety, the device should only be oper-

ated by qualified personnel and as described in the Oper-

ating Manual. It is also essential to comply with the legal

and safety requirements for the application concerned

during use. The same applies to the use of accessories.

The device is not intended for use as a safety compon-

ent. Please also follow the instructions in the "Additional

safety precautions" section. Proper and safe operation

requires proper transportation, correct storage, siting and

mounting, and careful operation.

Operating conditions

SProtect the device from direct contact with water.

SProtect the device from moisture and weather such as

rain or snow. The protection class of the device is

IP65 (DIN EN 60529).

SDo not expose the device to direct sunlight.

SComply with the maximum permissible ambient tem-

peratures and the data on maximum humidity as

stated in the specifications.

AED9101D

4I3563-1.0 en

SThe device must not be modified from the design or

safety engineering point of view except with our

express agreement. In particular, any repair or solder-

ing work on motherboards (replacement of compon-

ents) is prohibited. When exchanging complete mod-

ules, use only original parts from HBM.

SThe device is delivered from the factory with a fixed

hardware and software configuration. Changes can

only be made within the possibilities documented in

the manuals.

SThe device is maintenance free.

SPlease note the following points when cleaning the

housing:

- Disconnect the device from all current and voltage

supplies before cleaning it.

- Clean the housing with a soft, slightly damp (not

wet!) cloth. Never use solvent as this could damage

the labeling or the housing.

- When cleaning, ensure that no liquid gets into the

device or connections.

SIn accordance with national and local environmental

protection and material recovery and recycling regula-

tions, old equipment that can no longer be used must

be disposed of separately and not with normal house-

hold garbage, see Chapter 7, page 31.

Qualified personnel

Qualified persons means persons entrusted with the

installation, fitting, commissioning and operation of the

product who possess the appropriate qualifications for

their function.

AED9101D

I3563-1.0 en 5

This includes people who meet at least one of the three

following requirements:

SKnowledge of the safety concepts of measurement

and automation technology is a requirement and as

project personnel, they must be familiar with these

concepts.

SAs measurement or automation plant operating per-

sonnel, they have been instructed how to handle the

machinery. They are familiar with the operation of the

equipment and technologies described in this docu-

mentation.

SAs commissioning engineers or service engineers,

they have successfully completed the training to qual-

ify them to repair the automation systems. They are

also authorized to activate, ground and label circuits

and equipment in accordance with safety engineering

standards.

Working safely

SThe device must not be directly connected to the

power supply system. The supply voltage must be

between 10 and 30 VDC.

SError messages should only be acknowledged once

the cause of the error is removed and no further

danger exists.

SAutomation equipment and devices must be designed

in such a way that adequate protection or locking

against unintentional actuation is provided (e.g.

access checks, password protection, etc.).

SFor those devices operating in networks, safety pre-

cautions must be taken both in terms of hardware and

software, so that a line break or other interruptions to

AED9101D

6I3563-1.0 en

signal transmission do not cause undefined states or

loss of data in the automation device.

SAfter making settings and carrying out activities that

are password-protected, ensure that any controls that

may be connected remain in a safe condition until the

switching performance of the device has been tested.

Additional safety precautions

Additional safety precautions to meet the requirements of

the relevant national and local accident prevention regu-

lations must be taken in plants where malfunctions could

cause major damage, loss of data or even personal

injury.

The scope of supply and performance of the device cov-

ers only a small area of measurement technology. Before

starting up the device in a system, a project planning and

risk analysis must first be implemented, taking into

account all the safety aspects of measurement and auto-

mation technology so that residual dangers are minim-

ized. This particularly concerns personal and machine

protection. In the event of a fault, the relevant precau-

tions must establish safe operating conditions.

General dangers of failing to follow the safety

instructions

The device is state of the art and reliable. The device

may give rise to residual dangers if it is inappropriately

installed and operated.

2 Markings used

2.1 Symbols on the device

CE mark

The CE mark enables the manufacturer to guarantee that

the product complies with the requirements of the relev-

ant EC directives (the Declaration of Conformity can be

found on the HBM website (www.hbm.com) under HBM-

doc).

Statutory waste disposal mark

In accordance with national and local environmental pro-

tection 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.

Also see Section7 on page31.

3 Introduction

3.1 Scope of supply

SQuick start guide

SAED9101D (basic device)

A PDF of this operating manual is available on the HBM

website (www.hbm.com) under HBMdoc at Digital weigh

ing electronics.

3.2 Application

AED9101D digital transducer electronics are part of the

AED component family that digitally conditions signals

from mechanical transducers and networks them with

bus capability. They include digital amplifier boards, basic

devices with serial interfaces, and intelligent sensors with

integrated signal conditioning.

Using AED9101D digital transducer electronics, you can

connect SG1 transducers in a full bridge circuit directly to

a computer or a PLC. This enables you to configure com-

plete measuring chains quickly and with little extra work.

The AED9101D basic device takes AD101B or AD103C

amplifier boards. It provides mechanical protection,

shields the amplifier board (EMC protection) and allows

you to select RS-422 (factory setting), RS-485 or RS-232

serial interfaces. An amplifier board is not included in the

scope of supply of the basic device, and must be ordered

separately.

AED9101D transducer electronics is shortened in the

following text to AED (digital transducer electronics).

The AED_Panel32 PC software is available to facilitate

parameter settings, to display dynamic measurement

signals and for comprehensive analysis of the system.

Download your (free) software from the HBM website, at

Digital weighing electronics: www.hbm.com/HBM Soft-

ware. The AED commands are described in the online

Help of this program.

The DWS2103 digital indicator can be connected to all

AED basic devices and supports all the implemented

functions.

Tip

All the factory settings are stored in the amplifier, where

they are power failsafe and cannot be changed. The fact

ory settings can be restored at any time, using the TDD0;

command. Further information can be found in the online

Help of the AED_Panel32 program.
