Operating Instructions Option Module IEI for b maXX drive PLC BM4-O-
IEI-01
1INTRODUCTION
These operating instructions are an important component of your b maXX 4400; this
means that you must thoroughly read this document, not least to ensure your own safety.
In this chapter, we will describe the first steps that you should carry out after getting this
module. We will define terms that are used in this documentation on a consistent basis
and will inform you about the topics that you must consider when using this module.
1.1 First Steps
hCheck the shipment see ZPackaging and transportation – from page 15 onward.
hPass on all the documentation that was supplied with the plug-in module to the appro-
priate departments in your company.
hDeploy suitable personnel for assembly and commissioning.
hPass on these operating instructions to this personnel and ensure that they have read
and understood the safety instructions and that they are following them.
1.2 Terms Used
The abbreviation IEI stands for Incremental Encoder Interface).
In this documentation, we will also refer to Baumüller's "BM4-O-IEI-01" product as "mod-
ule", "plug-in module", "IEI option module", "IEI" or "incremental encoder interface".
We will also refer to the "BM4-O-PLC-01" Baumüller product as "b maXX drive PLC" or
"BM4-O-PLC" and we will use the term "b maXX" for the "b maXX 4400 basic unit".
For a list of the abbreviations that are used, refer to ZAbbreviations – from page 75 on-
ward.

2BASIC SAFETY INSTRUCTIONS
We have designed and manufactured each Baumüller plug-in module in accordance with
the strictest safety regulations. Despite this, working with the plug-in module can be dan-
gerous for you.
In this chapter, we will describe the risks that can occur when working with a Baumüller
plug-in module. Risks are illustrated by icons. All the symbols that are used in this docu-
mentation are listed and explained.
In this chapter, we cannot explain how you can protect yourself from specific risks in in-
dividual cases. This chapter contains only general protective measures. We will go into
concrete protective measures in subsequent chapters directly after information about the
individual risk.
2.1 Hazard information and instructions
Hazards are always divided into three danger classifications. Each danger classification
is identified by one of the following words:
DANGER
mConsiderable damage to property mSerious personal injury mDeath will occur
WARNING
mConsiderable damage to property mSerious personal injury mDeath can occur
WARNING
The following may occur,if you do not observe this warning information:
mserious personal injury mdeath
The hazard information is showing you the hazards which can lead to injury or even to
death.
Always observe the hazard information given in this documentation.

CAUTION
mDamage to property mSlight to medium personal injury can occur
2.1.1 Structure of hazard information
The following two examples show how hazard information is structured in principle. A tri-
angle is used to warn you about danger to living things. If there is no triangle, the hazard
information refers exclusively to damage to property.
The text next to the icons is structured as follows:
A triangle indicates that there is danger to living things.
The color of the border shows how severe the hazard is: the darker the color, the more severe
the hazard is.
The icon in the rectangle represents the hazard.
The color of the border shows how severe the hazard is: the darker the color, the more severe
the hazard is.
The icon in the circle represents an instruction. Users must follow this instruction.
(The circle is shown dashed, since an instruction is not available as an icon for each hazard
advisory).
The circle shows that there is a risk of damage to property.
The icon in the rectangle represents the hazard.
The color of the border shows how severe the hazard is: the darker the color, the more severe
the hazard is. (The rectangle is shown dashed, since the danger is not represented as an icon
with every hazard advisory)
THE SIGNAL WORD IS HERE THAT SHOWS THE DEGREE OF RISK
Here we indicate whether one or more of the results below occurs if you do not observe this
warning.
mHere, we describe the possible results. The worst result is always at the extreme right.
Here, we describe the hazard.
Here, we describe what you can do to avoid the hazard.

2.1.2 Hazard advisories that are used
If a signal word is preceded by one of the following danger signs: or or , the
safety information refers to injury to people.
If a signal word is preceded by a round danger sign: , the safety information refers to
damage to property.
2.1.2.1 Hazard advisories about injuries to people
To be able to differentiate visually, we use a separate border for each class of hazard in-
formation with the triangular and rectangular pictograms.
For danger classification DANGER, we use the danger sign. The following hazard in-
formation of this danger classification is used in this documentation.
For danger classification WARNING, we use the danger sign. The following hazard
information of this danger classification is used in this documentation.
For danger classification CAUTION, we use the danger sign. The following hazard
information of this danger classification is used in this documentation.
DANGER
The following will occur,if you do not observe this danger information:
mserious personal injury mdeath
Danger from: electricity. The hazard may be described in more detail here.
Here, we describe what you can do to avoid the hazard.
DANGER
The following will occur,if you do not observe this danger information:
mserious personal injury mdeath
Danger from: mechanical effects. The hazard may be described in more detail here.
Here, we describe what you can do to avoid the hazard.
WARNING
The following may occur,if you do not observe this warning information:
mserious personal injury mdeath
Danger from: electricity.The hazard may be described in more detail here.

Version 1.1 of Baumüller Nürnberg GmbH’s General Conditions of Sale and Conditions
of Delivery dated 2/15/02 or the respective latest version applies in all cases. These will
have been available to you since the conclusion of the contract at the latest.
2.6 Protective equipment
In transit, the plug-in modules are protected by their packaging. Do not remove the plug-
in module from its packaging until just before you intend to mount it.
The cover on the b maXX units' controller sections provides IP20 protection to the plug-
in modules from dirt and damage due to static discharges from contact. This means that
you must replace the cover after successfully mounting the plug-in module.
