The manufacturer declines any liability for damage arising from:

failure to comply with the provided documentation,

inappropriate use of the equipment.

Please note that all properties described refer to a closed measurement system and not to its individual slices. A

liability claim requires particularly careful handling of the unprotected individual slices (e.g. CRXT slices).

Guarantee

Each device is subjected to a 24-hour "burn-in" before leaving imc. This procedure is capable of detecting almost

all cases of early failure. This does not, however, guarantee that a component will not fail after longer operation.

Therefore, all imc devices are granted liability for a period of two years. The condition for this guarantee is that

no alterations or modifications have been made to the device by the customer.

Unauthorized intervention in the device renders the guarantee null and void.

Any additional products connected to the product must satisfy the EMC requirements as specified by the

responsible authority (within Europe1) in Germany the BNetzA - "Bundesnetzagentur" (formerly BMPT-Vfg. No.

1046/84 or No. 243/91) or EC Guidelines 2014/30/EU. All products which satisfy these requirements must be

appropriately marked by the manufacturer or display the CE certification marking.

Products not satisfying these requirements may only be used with special approval of the regulating body in the

country where operated.

All lines connected to the devices of the imc CRONOS system family should not be longer than 30m and they

should be shielded and the shielding must be grounded.

Note

The EMC tests were carried out using shielded and grounded input and output cables with the exception of

the power cord. Observe this condition when designing your experiment to ensure high interference

immunity and low jamming.

2 Safety

This section provides an overview of all important aspects of protection of the users for reliable and trouble-free

operation. Failure to comply with the instructions and protection notes provided here can result in serious

danger.

imc CRONOS-XT may only be operated as a completely closed system.

Responsibility of the operator

Devices of the imc CRONOS system family are for use in commercial applications. The user is therefore obligated

to comply with legal regulations for work safety.

Along with the work safety procedures described in this document, the user must also conform to regulations

for safety, accident prevention and environmental protection which apply to the work site. If the product is not

used in a manner specified by the manufacturer, the protection supported by the product may be impaired.

The user must also ensure that any personnel assisting in the use of the devices of the imc CRONOS system

family have also read and understood the content of this document.

Operating personnel

This document identifies the following qualifications for various fields of activity:

Users of measurement engineering: Fundamentals of measurement engineering. Basic knowledge of electrical

engineering is recommended. Familiarity with computers and the Microsoft Windows operating system. Users

must not open or structurally modify the measurement device.

Qualified personnel are able, due to training in the field and to possession of skills, experience and familiarity

with the relevant regulations, to perform work assigned while independently recognizing any hazards.

Warning

Danger of injury due to inadequate qualifications!

Improper handling may lead to serious damage to personnel and property. When in doubt, consult qualified

personnel.

Work which may only be performed by trained imc personnel may not be performed by the user. Any

exceptions are subject to prior consultation with the manufacturer and are conditional on having obtained

corresponding training.

Page 12

Chapter 2

Special hazards

This segment states what residual dangers have been identified by the hazard analysis. Observe the safety notes

listed here and the warnings appearing in subsequent chapters of this manual in order to reduce health risks and

to avoid dangerous situations. Existing ventilation slits on the sides of the device must be kept free to prevent

heat accumulation inside the device. Please operate the device only in the intended position of use if so

specified.

Danger

Lethal danger from electric current!

Contact with conducting parts is associated with immediate lethal danger.

Damage to the insulation or to individual components can be lethally dangerous.

Therefore:

In case of damage to the insulation, immediately cut off the power supply and have repair

performed.

Work on the electrical equipment must be performed exclusively by expert electricians.

During all work performed on the electrical equipment, it must be deactivated and tested for

static potential.

Injuries from hot surfaces!

Devices from imc are designed so that their surface temperatures do not exceed limits

stipulated in EN 61010-1 under normal conditions.

Therefore:

Surfaces whose temperature can exceed the limits under circumstances are denoted by the

symbol shown at left.

The click mechanism allows CRFX- or CRXT slices to be quickly connected and disconnected. The click

connections should always be secured to prevent unintentional unlocking.

In a wet environment, even low voltages can lead to dangerous flow through the body. For this reason, assemble

the CRXT modules with special care, ensuring that the seals are clean and greased (e.g. with Vaseline) and use

the supplied connecting elements. In a wet environment, no special modules with a protection degree lower

than IP67 may be used.

Industrial safety

We certify that imc CRONOS systems in all product configuration options corresponding to this documentation

conforms to the directives in the accident prevention regulations in "Electric Installations and Industrial

Equipment" (DGUV Regulation 3)*. This confirmation applies exclusively to devices of the imc CRONOS system

family, but not to all other components included in the scope of delivery.

This certification has the sole purpose of releasing imc from the obligation to have the electrical equipment

tested prior to first use (§ 5 Sec. 1, 4 of DGUV Regulation3). This does not affect guarantee and liability

regulations of the civil code.

For repeat tests, a test voltage that is 1.5 times the specified working voltage should be used to test the isolation

for the highly isolated inputs (e.g. measurement inputs for high-voltage applications).

Page 13

Chapter 2

Observe notes and warnings

Devices from imc have been carefully designed, assembled and routinely tested in accordance with the safety

regulations specified in the included certificate of conformity and has left imc in perfect operating condition. To

maintain this condition and to ensure continued danger-free operation, the user should pay particular attention

to the remarks and warnings made in this chapter. In this way, you protect yourself and prevent the device from

being damaged.

Read this document before turning on the device for the first time carefully.

Warning

Before touching the device sockets and the lines connected to them, make sure static electricity is diverted

to ground. Damage arising from electrostatic discharge is not covered by the warranty.

After unpacking... Chapter 3

3 Assembly and connection

3.1 After unpacking...

Check the delivered system immediately upon receiving it for completeness and for possible transport damage.

In case of damage visible from outside, proceed as follows:

Do not accept the delivery or only accept it with reservations

Note the extent of the damage on the packing documents or on the delivery service's packing list.

Begin the claims process.

Please check the device for mechanical damage and/ or loose parts after unpacking it. The supplier must be

notified immediately of any transportation damage! Do not operate a damaged device!

Check that the list of accessories is complete (product package):

AC/DC-power adaptor with cable and pre-assembled XT-Con plug (Fig. 1 item A )

Getting started with your imc measurement device (printed)

Note

File a claim about every fault as soon as it is detected. Claims for damages can only be honored within the

stated claims period.

3.2 Before commissioning

If components are brought into the operating room from a cold environment, condensation may occur. Wait

until the CRXT slices are adapted to the ambient temperature and absolutely dry before clicking them together

to form a system.

The click mechanism allows CRFX- or CRXT slices to be quickly connected and disconnected. The click

connections should always be secured to prevent unintentional unlocking.

Good radiation and convection conditions must be ensured to prevent heat build-up inside the device. The

devices must not be operated if there is a danger of explosion or if they are exposed to aggressive chemicals.

Ambient temperature

The limits of the ambient temperature cannot be strictly specified because they depend on many factors of the

specific application and environment, such as air flow/convection, heat radiation balance in the environment,

contamination of the housing / contact with media, mounting structure, system configuration, connected cables,

operating mode, etc. This is taken into account by specifying the operating temperature instead. Furthermore, it

is not possible to predict any sharp limits for electronic components. Basically, reliability decreases when

operating under extreme conditions (forced ageing). The operating temperature data represent the extreme

limits at which the function of all components can still be guaranteed.

3.3 Notes on connecting

3.3.1 Precautions for operation

Certain ground rules for operating the system, aside from reasonable safety measures, must be observed to

prevent danger to the user, third parties, the device itself and the measurement object. These are the use of the

system in conformity to its design, and the refraining from altering the system, since possible later users may not

be properly informed and may ill-advisedly rely on the precision and safety promised by the manufacturer.

Page 15

Notes on connecting Chapter 3

Note

If you determine that the device cannot be operated in a non-dangerous manner, then the device is to be

immediately taken out of operation and protected from unintentional use. Taking this action is justified under

any of the following conditions:

the device is visibly damaged,

loosed parts can be heard within the device,

the device does not work,

the device has been stored for a long period of time under unfavorable conditions (e.g. outdoors or in

high-humidity environments).

1. Observe the data in the manual chapter "Technical Spes" in order to prevent damage to the unit through

inappropriate signal connection.

2. Note when designing your experiments that all input and output leads must be provided with shielding

which is connected to the ground ("CHASSIS") at one end in order to ensure high immunity to interference

and noisy transmission.

3. Note that parts that are not explicitly intended to be carried may be warmer than the handles. The use of

handles is mandatory for safe use. Otherwise other suitable methods must be used to ensure acceptable

protection against burns. Under normal conditions, the surface temperature of the enclosure/housing

does not exceed the limits for accidental contact according to IEC 61010-1.

4. For the correct use of the imc click mechanism please observe to the instructions in the chapter

"Attachment mechanism ". The rubber seals must be clean (see Cleaning) before connecting CRXT

modules together.

5. Unused, open channels (having no defined signal) should not be configured with sensitive input ranges

since otherwise signal quality of the device could be affected. Configure unused channels with an

insensitive input range or short them out. The same applies to channels not configured as active.

6. In case you are using a removable storage medium,

please be aware that before you remove it (if the device is switched on), the button must be pressed to

ensure that storage medium can be safely removed.

7. The CRXT device may only be disassembled into its slices in a controlled environment and must also be

clicked together to form a closed CRXT device in a controlled environment. Only complete (closed) CRXT

devices may be used in a non-controlled environment.

Page 16

Notes on connecting Chapter 3

3.3.2 Attachment mechanism

Stacking the modules

1. Check the greased rubber seal for cleanliness

2. Make sure that the blue slider (protective function) is in position "open" (the blue handles of the slider are

not aligned with the cooling fins of the housing)

3. Hook the front side of the modules into each other

4. Compress the rear side of the modules

5. For checking press the locking rocker and

6. Check the protective function: the blue handles of the slider are in alignment with the cooling fins of the

housing, see Fig. 1

Detaching modules

1. Release the protective function and press the locking rocker

2. Detach modules from each other

Protective function

Until May 2020 the locking rocker was equipped with a locking screw so that the rocker cannot be operated. As

of May 2020 the rocker will be equipped with a locking slide in blue color. With this slider the rocker can be

fixed without tools.

Warning

All sliders respectively locking screws should be tightened before switching on the system.

Note

During operation respectively powered device: modules should not be disconnected from the system To

avoid damage:

Before clicking together or removing modules, switch off the system and disconnect the supply lines. (hot

plug functionality is not supported during a running measurement).

A maximum total length of 0.5 m of attached (clicked) modules should be observed!

The rubber seals must be greased and clean so that the system is well sealed.

The CRXT handles are mandatory for the safe transport, handling and sealing of a module block.

Sealing, IP rating and environmental specs

A single base unit or single CRXT slices cannot achieve an IP protection level at first because it is left open at the

side. The given specifications are always only valid for a complete in a controlled environment clicked (closed)

CRXT system. Only after it has been combined with a CRXT base unit (plus power module), CRXT slices if

applicable, and the final sealing handles to form a complete CRXT system, sealing and environmental properties

can be determined. The specification for shock, vibration and IP degree of protection applicable to the entire

device is then derived from the weakest specification of the CRXT slices used in this combination (given in the

technical data sheets of the respective CRXT slices). They assume that the individual CRXT slices are each

mounted in conjunction with the additional stabilizing interconnect brackets (included in the standard

accessories supplied).

Page 17

Notes on connecting Chapter 3

According to IEC 60529 the Ingress Protection (IP) rating refer to protection classes provided by a housing, the

protection of the electrical parts within the housing shell. If all functionally accessible contacts of the sockets are

also to be protected, the corresponding plugs must be connected to all sockets. In many cases, a protective

cover can also be used alternatively on unused sockets.

Reference

The sizes (drawings) of all available modules are listed in the data sheets of the modules and the base unit.

The dimensions, the spacing of threadings for available mounting elements are stated in this separate

document: "Description of the mounting systems".

Notes on connecting Chapter 3

3.3.4 Building Block Principle

An imc CRONOS-XT (CRXT) system is composed of a base unit plus a power supply module and one or more CRXT

modules as well as the system sealing handles (left and right). The individual modules are constructed to form a

tight mechanical connection. At the same time, the "click" establishes an electrical connection to the system bus

and the power supply. Clicking (or releasing) the CRXT slices together is only allowed in a controlled

environment. The resulting measurement system can be manged from a PC which serves as the configuration

tool and repository for measured data. Additional fastening elements are recommended for particularly

harsh conditions. Please refer to the CRXT base unit data sheet for vibration specifications and IP protection

level.

3.3.5 Networking and power supply

The power supply of a CRXT system is provided

exclusively via the power socket (Fig. 2 item A) by the

POWER Module. If the supply voltage fails, an internal

buffer keeps the base unit of the device active for a

few seconds to complete the measurement save data

files and then automatically shuts itself off. Short-time

buffering to ensure data integrity is always a standard

part of the system.

Main switch

The CRXT base unit has a central main switch (Fig. 2

itemB) by which the complete block of directly clicked

(stacked) modules is activated/deactivated. As an

alternative to the manual main switch on the device's

front panel, a remote-controllable electric contact can

be used to switch the system on and off. Both the

extended POWER module (CRXT/POWER-X) and the

base unit are equipped with a REMOTE socket .

3.3.6 POWER-X functions

Within an imc CRONOS-XT device the POWER-X module fulfills the function of an extended system supply. It can

be used as an alternative to the simple POWER module, which only provides the simple supply voltage feed via

XT-Con socket. The POWER-X module offers the following extended functions:

Voltage converter for internal 34 V DC link

Available interface for connection of distributed EtherCAT-based amplifiers of the imcCRONOSseries (CRXT

and CRFX)

Support of Power-over-EtherCAT (PoEC) for distributed CRXT systems

centrally remote controlled switching on of distributed amplifier blocks

Page 20

Notes on connecting Chapter 3

3.3.6.1 Voltage converter

In the sense of a "Step-Up" converter the connected supply voltage is raised to a constant device-internal

intermediate circuit of 31Vto35V. This allows in particular the operation of larger devices with low supply

voltages, such as the 12V on-board power supply in vehicles, since the currents via the module click connectors

(subject to limits) are reduced accordingly.

3.3.6.2 EtherCAT System bus

The internal EtherCAT system bus of the device is provided to the outside via M8 sockets, thus enabling the

operation of distributed systems. These can be composed of a master device (base unit with or without further

amplifier modules) and spatially separated blocks of amplifiers (slaves). CRXT amplifier blocks must in turn be

equipped with a POWER-X module. Such distributed systems can also be combined from slices of

imcCRONOS-XT (CRXT) and imcCRONOSflex (CRFX). This means that distributed flex amplifier modules can be

operated on an XT device and a flex base unit can also be combined with an XT amplifier block (with POWER-X).

Suitable connection cables with mixed connection technology (M8 to RJ45) are available. Networking via

EtherCAT can also extend over several stages:

A further slave can be connected to a slave block via cable (EtherCAT IN/OUT).
