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

danger.

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.

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 plug

LEMO plug for DC-powering

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 commisioning

Condensation may form on the circuit boards when the device is moved from a cold environment to a warm

one. In these situations, always wait until the device warms up to room temperature and is completely dry

before turning it on. The acclimatization period should take about 2 hours. This is especially recommended for

devices without ET (extended environmental temperature range).

We recommend a warm-up phase of at least 30 min prior to measure.

Existing ventilation slits (e.g. CRFX modules) must be kept unimpeded to avoid heat buildup in the device

interior.

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/single or block

(click), 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.

Page 15

Precautions for operation Chapter 3

3.3 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.

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 chapter "Technical specifications" and the application hints about the individual

system 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 resistance to

interference and noisy transmission.

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

since otherwise the measurement data could be affected. Configure unused channels with a broad input

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

4. To measure voltages >60 V use adequate plug.

5. 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 (1) must be pressed to ensure that storage medium can be safely

removed. Please read the instructions in the chapter "removable storage".

6. Avoid prolonged exposure of the device to sunlight.

7. Be certain that the ventilation slits remain unobstructed.

8. 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. In the event of deviations, 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. The handles

also prevent the lateral plug contacts from being touched during a measurement, thus preventing

accidental discharge (ESD) into the lateral plug contacts. ESD in the lateral plug contacts can lead to a

crash of a running measurement (destruction does not take place).

Note

Handling

Be aware that during a running measurement, modules should not be disconnected from the system (hot

plug functionality is not supported during a running measurement).

To avoid damage: Before clicking together or removing modules and power handles, disconnect the supply

lines and switch the system off, in order to ensure that the system is disconnected from the supply voltage.

The CRFX handles are mandatory for the safe transport and handling of a module block: e.g. CRFX/HANDLE-L

(left, 11900008) and CRFX/HANDLE-R (right, 11900007).

A maximum total length of 85 cm of attached (clicked) modules should not be passed!

Mounting elements can be used for more stability.

The sizes (drawings) of all available modules are listed in a separate document (data sheet). The dimensions,

the distances of the bore holes for available mounting elements are also stated in this separate document.

imc CRONOSflex Description of the system Chapter 3

3.6 imc CRONOSflex Description of the system

3.6.1 Building Block Principle Maximizes Flexibility

The inherently modular construction of imc CRONOSflex eliminates the constraints of a predefined system size

or configuration , found in usual data acquisition systems. Integrated modules free the user to design – and

redesign – their system as required: small and compact one day; a large number of channels, of different sensor

types with tailored signal conditioning the next. Today a centralized bench top system; tomorrow a

decentralized system with satellite modules each assigned to a remote measurement site. The flexibility of imc

CRONOSflex allows the reuse of system components to build the optimal solution in a matter of seconds; the

system's scalable and expandable architecture eliminates the need for exact planning when purchasing

equipment for a specific application. Based on EtherCAT, the system bus to connect the central base unit

with measurement modules, it is possible to both connect the measurement modules directly to a central unit,

and/or to set up a spatially distributed system by means of standard Ethernet network cables (RJ45, CAT5). The

resulting measurement system can be managed from a PC (also connected via an Ethernet LAN or WLAN) which

serves as the configuration tool and repository for measured data.

However, the system can also work autonomously without a control PC: either starting immediately upon being

powered, or automatically at a specified time according to a pre-set autostart configuration. In either case, the

recorded data may be saved to the device's storage (hard drive, flash card or USB media), or to a network drive.

Data can be retrieved from a remote device directly (removable storage media), or via the network if there is a

(temporary) outside connection.

3.6.2 System bus

The selection of EtherCAT as the system bus provides the user with the advantage of being able to set up a

distributed measurement system with standard CAT 5 network cables, including those in an existing Ethernet

infrastructure. EtherCAT's software protocol is an established industry standard which supports deterministic

transfers and synchronization mechanisms, guaranteeing precisely synchronized measurements throughout the

network.

3.6.3 Modular components "click" together

The individual modules are constructed to form a tight mechanical connection "with a click", while being

electrically connected to the imc CRONOSflex data bus and, if desired, power. When added or removed,

hardware modules are also automatically included/excluded by the imc STUDIO software. An optional powered

handle unit can be attached to the stack in the same manner as imc CRONOSflex Modules, optionally containing

a stabilized 50 V system power supply unit with buffered uninterruptible power supply (UPS). When "clicking

together (connecting the components)" modules in this way, you create a portable, centralized measurement

system which can subsequently be customized both in terms of the module types and quantity.

3.6.4 Distributed measurement system

For even more flexibility, the EtherCAT based imc CRONOSflex system can be physically distributed using

standard cables (RJ45, CAT5). Additional measurement modules can be connected, individually and as local

blocks of modules which are locally clicked together, but remote from the base unit. The combination of these

two connection techniques, centralized "clicked" stacks and distributed cable connected modules and substacks,

allows any imaginable topology of measurement locations to be joined together into a logically integrated,

centrally controlled, data acquisition and control system.

imc CRONOSflex Description of the system Chapter 3

3.6.4.1 System structure and components

A complete system always consists of a central imcCRONOSflex base unit and a flexible amount of

imcCRONOSflex modules (AMP). The imcCRONOSflex base unit is available as a variety of models. With either

one or two fieldbus interfaces (each with two nodes), as well as an optional Multi-IO extension, which provides

digital inputs and outputs plus incremental counter measurement channels and analog outputs.

3.7 Networking and power supply

All of the system's individual building blocks, both the imc CRONOSflex base unit and also each individual

imcCRONOSflex measurement module, have their own LEMO sockets for an ultra-wide 10 to 50 V range of DC

power input; additionally, each have two RJ45 network jacks (IN/OUT) for connecting the EtherCAT system bus.

Both lines have robust connection terminals which provide both mechanical attachment to modules (locking

snap) and electrical connection without any additional cables. By this means, multiple directly attached

modules can be jointly powered by a single DC source which is always connected at the "far left" or "first"

module . If multiple power sources are accidentally connected to the same block of modules, then a latch

circuit ensures that only the first module on the left receives the power.

With the introduction of the 48 VDC power adaptor for the imc CRONOSflex system (CRFX base unit and the

CRFX input modules), the power supply socket on the device has been changed so that the 48 VDC power

adaptor can only be used with imc CRONOSflex systems and not with other imc measurement devices with an

input supply voltage of 10..32 VDC. You can identify the 48 VDC power adaptor at the blue protective sleeve at

the LEMO.1B plug (LEMO.PHG.1B.302), see the following Fig. The 15VDC or the 24 VDC power adaptors are

equipped with a black protective sleeve at the LEMO.1B plug and can also be used with imcCRONOSflex

systems. The use of those power adaptors with imcCRONOSflex is not recommended. The imcCRONOSflex

system have an input supply voltage range of 10 .. 50VDC. The DC-supply inputs of our imc measurement

devices are not designed for a connection to a DC-grid.

If the imc CRONOSflex base unit runs with 48VDC power supply rather than the 24 VDC power supply, it is

possible to operate a larger number of modules or a module with more power consumption directly with one

power adaptor. The power consumption of the modules can be as high as 149W with a 48VDC power supply. If

you want to benefit of the Power over EtherCAT (PoEC) function a minimum voltage of 42VDC is necessary.

For all previously delivered imc CRONOSflex systems with the LEMO.EGG.1B power supply socket (with one

guide keyway), to be powered in future with 48 VDC, use the adaptor cable "CRFX adaptor cable for the supply

LEMO.1B (article number: 13500151, order code: ACC/FGG-ADAP-PHE)" and the 48VDC power adaptor.

Note

This adaptor cable may only be used with imc CRONOSflex. For devices with the 10..32 VDC input voltage range

(imcC-SERIES, imcSPARTAN, …), use of this adaptor cable and the 48 VDC power unit can damage or destroy

the devices.
