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

corresponding training.

Page 11

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

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.

For an overview of the accessories supplied as standard, please refer to the data sheet of the supplied ARGUSfit

module. Check the accessories for completeness.

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

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.

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.

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:

I. the device is visibly damaged,

II. loose parts can be heard within the device,

III. the device does not work

IV. 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 Specifications", 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. If you are using a removable storage media, observe the notes in the imc software manual.

Particular care should be taken to comply with the storage device's max. ambient temperature limitation.

5. Avoid prolonged exposure of the device to sunlight.

Due to their function, the imc ARGUSfit modules, just like the CANSASfit modules, are open at the connection

points (module connectors). This is not a problem when used in a controlled, dry environment. In order to

protect a module (or even a group connected in series) against foreign objects and moisture, please carry out

the following measure:

Attach covers over the module connectors on the upper and lower sides.

Two covers per module are fixed at the left side of the module (parking position).

Notes on connecting Chapter 3

3.3.3 Power supply

An imc ARGUSfit system can be operated with a DC supply voltage that is fed to the overall system via a socket

compatible with LEMO.EGE.0B.302 on the base unit ("POWER").

The permissible supply voltage range is 10 to 50 V DC (ultra-wide range). For the AC/DC adapter ("desktop

power supply") supplied with the base unit, the specified AC voltage range on the input side is 110 V.. 240 V

50/60 Hz. With regard to EN 61326-1 and EN 61010-1, the DC supply inputs are not specified for connection to a

DC mains supply.

Connecting a DC supply source such as a car battery is also fundamentally possible. Please note when making

such a connection:

Grounding of the imc ARGUSfit system must be provided. If the supply voltage source has a ground

reference (ground connection to the (-)terminal, then the device is automatically grounded via the (-)

terminal. The supplied power adaptor is prepared in this way.

The supply line must be of low impedance via a cable with a sufficient cross-section. Any (interference

suppression) filters (interference suppression) filters in the supply circuit should not contain series

inductances greater than 1mH. should be present. Otherwise, an additional parallel capacitor is necessary.

CANFT

CAN node 1 is available on the ARGFT base unit for connecting CANFT modules

via a LEMO cable. The 5-pin LEMO socket on the base unit is marked:

"CANSAS". The CANFT modules connected via this LEMO socket are directly

supplied by the ARGFT system supply (is not related to CAN-GND),

see Fig. 6 . A further supply of the CANFT modules is not necessary and

must not be carried out (see CANFT topology in the section Commissioning of

the imcCANSAS - Modules and Software Manual).

The external CAN connections of the CANFT modules "clocked on" to the base unit (CAN

node2) are switched off, see Fig. 5.

Notes

Termi:

The CAN terminator 120 Ω, LEMO.0B plug (ACC/CANFT-TERMI, 13500242) must only be connected to the

CANFT module block, which is connected to the base unit (CANSAS) via a LEMO cable, see Fig. 6. The

CANFT modules directly coupled to the ARGFT base unit are automatically terminated via ARGFT and do

not require a termi.

Note that the operating temperature of the power supply adaptor is designed for 0 °C to 40 °C. This also

applies if your unit should be suitable for an extended temperature range.

When connecting the power supply, please note that the supply line must be of low impedance via a

cable with a sufficient cross-section. Any additional (interference suppression) filters connected in the

supply circuit should not contain series inductances greater than 1 mH. Otherwise, an additional parallel

capacitor is necessary.

Notes on connecting Chapter 3

3.3.4 Fiber Converter

The Fiber Converter is a clickable module for the modular imc ARGUSfit system. It allows decentralized

distributed system topologies.

The module converts the internal high-speed ARGUS system bus, which connects the ARGUS measurement

amplifier and interface modules via the click connector, to a fiber-optic data link in the sense of a media

converter. Thus, the click connection can be extended to a spatially distributed arrangement of the entire ARGUS

system by a pair of converters (master/slave) and a fiber optic cable.

The remote module block uses a joint power supply at is fed into the slave converter module.

Fiber converter application

One fiber converter each is clicked onto the right (master) or left (slave) side of an imc ARGUSfit module block.

The converters have a uniform design and recognize their master/slave function automatically:

Base unit block

Master converter

Satellite block #1

further #2..n

The voltage supply of the base block is realized via the supply socket of the base unit. The power supply of the

satellite block (ARGFT module block #1) and possibly further module blocks #2..n is realized via the supply socket

of the slave fiber converters clicked onto these module blocks. For this purpose, a DC supply voltage or an AC/DC

mains adapter must be connected to the LEMO.0B (2-pin) "POWER" socket of the converter (optional accessory).

For these module blocks #2..n, the same specified AC voltage range applies on the input side, as well as the note

regarding EN 61326-1 and EN 61010-1 as for the base unit in chapter "Power supply ".

If the slave fiber converter detects no signal activity via the connected fiber cable, it deactivates the power

supply of the clicked modules and the slave fiber converter is in sleep mode with reduced power consumption. If

signal activity is detected, the power supply for the clicked modules is switched on. Thus, switching off the base

unit always leads to switching off the satellite module blocks as well, and the slave fiber converters are put into

sleep mode.

3.3.5 UPS-NiMH

Powering on/off

The supply module (ARGFT/UPS-NIMH) switches on when

the module's own pushbutton is pressed and an external supply is applied via the "POWER IN" socket at the

same time.

a pushbutton connected to the module's own "REMOTE" socket is pressed and at the same time an

external supply is applied via the "POWER IN" socket.

a switch connected to the module's own "REMOTE" socket is closed and an external supply via the "POWER

IN" socket is applied at the same time.

An imc ARGUSfit-BASE connected to the power supply module receives a shutdown command via the plugged

"REMOTE" accessory cable during operation or the power supply module switches off without an imc ARGUSfit-

BASE connected when / if

the module's own button is pressed.

a button connected to the module's own remote socket is pressed.

a switch connected to the module's own remote socket is opened.

if an overload case occurs (for details see section "Output power" and section "Output-side overcurrent

protection" ).

if the UPS buffer duration has expired or the battery is completely discharged in battery mode.

The supply module switches off with the imc ARGUSfit-BASE connected if

the imc ARGUSfit-BASE, after being active, has been shut down and has switched itself off.

the imc ARGUSfit-BASE has still not switched itself off 20 seconds after a shutdown command (error case

with the imc ARGUSfit-BASE).

If the power supply module does not respond to all attempts to switch it off, it can be switched off by pressing

the module's button for at least 4seconds. This prevents damage to the batteries due to deep discharge.

Reference

For the power supply module, the same specified voltage range applies on the input side, as well as the

note regarding EN 61326-1 and EN 61010-1 as for the base unit in chapter "Power supply ".

Remote socket

The supply module has a "REMOTE" socket for switching the supply module on and off and a "REMOTE OUT"

socket for switching an imc ARGUSfit base unit on and off.

The assignment of the "REMOTE" socket is identical to the assignment of other imc supply modules (e.g. imc

CRFX/HANDLE-xxx). A static switch (between pin1 and pin2) or a push button (between pin3 and pin4) can be

connected for switching on and off.

A jumper between GND (pin1/3/5) and -MUTE (pin6) can be used to mute the internal buzzer of the supply

module for buffer operation.

In order for the supply module to switch the imc ARGUSfit-BASE on and off, the corresponding accessory cable

must be connected between "REMOTE OUT" and the "REMOTE" socket on the imcARGUSfit-BASE, see Fig. 7 .

Page 20

Notes on connecting Chapter 3

Output voltage for connecting the imc ARGUSfit-BASE and additional measuring modules.

The supply module passes the external supply voltage unregulated to the output. In buffer mode, the internal

battery voltage is regulated to approx. 12 V and applied to the output. The supply module has three "POWER

OUT" sockets connected in parallel, to which the output voltage for the connected devices is applied. The

available output power of the module is divided between all three connections. The assignment is identical with

the "POWER IN" socket. In order for the supply module to supply the imcARGUSfit-BASE, the corresponding

accessory cable must be connected between "POWER OUT" and the "POWER" socket on the imcARGUSfit-BASE,

see Fig. 7 .

Fig. 7: Power supply via ARGFT/UPS-NIMH (power supply module)

Output power

The supply module has an extended wide range input of 10..50VDC. In this range an output power of 50W is

available. Below 10VDC it is switched to battery operation. At low temperatures, the performance of the

accumulators is limited, which means that the full output power may not be available in the buffer case. It is

reduced by 1W/K below +15°C.

Output-side overcurrent protection

Since theoretically any number of modules could be connected to the supply module, the supply module has

two independent current limiting circuits to protect the internal circuitry:

1. short-circuit protection (reaction time 10..30ms)

2. static overload protection (reaction time approx. 1s)

The short-circuit protection limits the output current to a resulting output power of typically approx. 70..85W,

depending on the output voltage. If this limit is exceeded, the output voltage is cut after approx. 10..30ms and is

only enabled again after approx. 4 seconds. If the short-circuit has not been eliminated then, another 4 seconds

are waited and so on. During this "waiting" the "LIMIT" LED of the supply module flashes red every second.

The overload protection measures the output power every second, evaluates it and will shut down the system in

case of a static overload. If the permissible static output power of 50 W is exceeded, a shutdown process is

initiated after 10 seconds (after 1 second in the buffer case). The "LIMIT" LED lights up yellow at an output

power > 80 % and red at an output power > 95 % of the maximum permissible static output power.
