1.2 Features of the MIQ/Blue PS

1.2.1 General characteristics

With the aid of the MIQ/Blue PS SET you can replace an
IQ S

ENSORNET line section by a radio link. When doing so a new

IQ S

ENSORNET island is formed (Fig. 1-2):

Fig. 1-2 Structure of a radio link with the MIQ/Blue PS SET

Radio technology using Bluetooth modules features reliability and
insensitivity to foreign electromagnetic radiation. Transmission
between two MIQ/Blue PS modules of a set takes place in an encoded
form. In conjunction with the proprietary IQ S

ENSORNET record, the

transmission is thus tap-proof.

The antennas of the MIQ/Blue PS modules are omni-antennas without
directivity.

Power supply To supply an IQ S

ENSORNET island with power, a line power supply unit

is integrated in the MIQ/Blue PS. I can supply components with a total
power consumption of up to 7 watt, which is sufficient for most applica­tions. The line power supply unit of the MIQ/Blue PS can be supplied
with line power or with 24 V. Thus, an island can also be supplied by a
battery or solar system.

Terminal strip The MIQ/Blue PS has the following electrical connections on the termi-

nal strip inside the enclosure:

 1 x line power connection 100 ... 240 VAC, two-pole
 1 x line power connection 24 VDC, two-pole
 3 x SENSORNET connections

The nameplate is on the side of the module enclosure. Among other, it
contains the following information (Fig. 1-3):

Fig. 1-3 Nameplate of the MIQ/Blue PS

ID number and encoding An MIQ/Blue PS SET consists of a module pair with the same ID num-

ber. Every module pair has its own coding of the radio transmission,
which is determined via the ID number. Any ID number is assigned only
once by YSI.This excludes the possibility of several module pairs hav­ing the same encoding and thus, of interferences by a module pair that
happens to have the same encoding. With several MIQ/Blue PS pairs,
the ID number enables to identify which pair communicates with each
other.

 Operating manual.

3.2 Basic information on installation

3.2.1 General information

The MIQ/Blue PS radio modules are preconfigured in pairs and ready
for installation. Installation consists only of the connection to the
IQ S

ENSORNET.

Note

This chapter describes the installation of one radio link in the
IQ S

ENSORNET system. If several radio links should be installed, the

instructions in the appendix of this operating manual have to be fol­lowed additionally.

Note

To prevent the radio transmission from being affected by water or snow
collecting on the antenna, we urgently recommend protecting any MIQ/
Blue PS radio modules against precipitation with the aid of a plastic
canopy (SSH/IQ).

ENSORNET island. In any case, a separate

ENSORNET island.

Compatibility with other

line power supply units

Example Problem:

24 V DC operation: 24 W
100 ... 240 V AC operation: 7 W

If the installation of further line power supply units should be necessary,
please note the following: If other power supply modules (e.g. MIQ/PS)
are installed on the IQ S

ENSORNET island, the line power supply unit of

the MIQ/Blue PS is automatically inactive. Connecting the MIQ/
Blue PS line power supply unit to a power supply remains ineffective
here. In this case, the MIQ/Blue PS is a consumer with a power con­sumption of 0.6 W in the power rating.

 An IQ SENSORNET island should consist of the following compo-

nents plus the MIQ/Blue PS:

MIQ/CHV PLUS 1.0
MIQ/TC 2020 XT (docked from time to time) 3.0

 In this example, the MIQ/Blue PS and the MIQ/CHV PLUS should

be mounted as a stack.

 The IQ S

ENSORNET system should be supplied with 100 ...

240 V AC.

Solution/proceeding:
 First it is assumed that the MIQ/Blue PS suffices for power supply.

It does not have to be taken into account as a consumer. In the worst
case, i. e. with a docked MIQ/TC 2020 XT, the power requirement of
all components is 7.2 W. Power losses in cables do not have to be
taken into account due to the stack mounting.

 Power rating: The calculated power requirement is greater than the

maximum power delivery of the MIQ/Blue PS line power supply unit.
Therefore, an additional power supply module has to be installed
(e.g. MIQ/PS).

 New power rating: The MIQ/Blue PS has to be counted as a con-

sumer as well. Therefore, the power consumption is now 7.8 W.

3.2.3 Topology and terminator switch

For failure-free operation, the terminator switches (terminating resis­tors) must always be set to ON on two MIQ modules of the

ENSORNET island. On which modules this is required results from

3.3 Radio range

The range of a radio link with MIQ/Blue PS SET in the free field is up to
100 m with installation and testing according to this chapter (see
chapter 6 T

As with any other radio technology, the following points have to be
observed when installing the MIQ/Blue PS SET:

 All materials (even window glass) in the radio link reduce the range.

Therefore, keep the radio link free of barriers (even temporary
ones). Both MIQ/Blue PS modules should be in permanent "visual
contact" through the air. Take into account that there may be short­time events such as trucks driving by that interrupt the radio link.

 Water, snow and ice on the antenna will reduce the range. When it

is installed in the free field, protect the MIQ/Blue PS against water,
snow and ice. Use the plastic canopy SSH/IQ for this.
Canopies made out of metal or PVC reduce the range!

 A high location of the MIQ/Blue PS increases the range. If neces-

available and establish the connection to the IQ S

ENSORNET island

with the aid of the SNCIQ cable. Do not in any case use an antenna
extension cable to improve the position of the antenna alone.
Antenna extension cables cause range losses.

 Mount the MIQ/Blue PS outside of a building on a pole and run the

SNCIQ cable through the wall to the next MIQ module.

MIQ/Blue PS Installation

Note

If it is not possible to keep the minimum distances of the MIQ/Blue PS
masters, you can reduce interferences of the radio communication by
shielding the modules against one another (e.g. by using directional
antennas with side-lobe suppression in conjunction with attenuators). If
necessary, contact a radio technology specialist.

Note

If high gain antennas in order to increase the range are used, the
requirements of the directive 1995/5/EC will not be met.

Range test with

attenuator

To test the quality of the radio link, carry out the following test with a
defined signal attenuation:

Note

If a canopy is used, the MIQ/Blue PS has to be mounted lower on the
canopy for the duration of the range test. If necessary, use the lower
boreholes in the plastic canopy (SSH/IQ) for this.

1 Unscrew the antenna from on of the two MIQ/Blue PS mod-

ules. For the test, insert the attenuator with both adapters
between the antenna connector of the module enclosure and
the antenna.

2 Test the radio link with the attenuator under the most unfavor-

able conditions such as with installation on rotating scraper
bridges and the utmost distance of both MIQ/Blue PS mod­ules.
If the test is successful with signal attenuation, faultless oper­ation should also be possible under unfavorable conditions
(e.g. fog, heavy rainfall, snow).

3 To terminate the test operation, remove the attenuator and

mount the antenna directly on the MIQ/Blue PS again.

ba76095e02 01/2013

4 If you had mounted the MIQ/Blue PS lower on the canopy for

the test:
Mount the MIQ/Blue PS higher on the canopy again.

Installation MIQ/Blue PS

Radio link check list:

1 Is there direct visual contact between the antennas of both

MIQ/Blue PS modules at any time (e.g. with installation on
moving scraper bridges)?

2 Is the radio link free from permanent disturbances? Examples:

– Obstacles (such as buildings, windows, etc.)
– Shielding (such as a metal or PVC canopy)

3 Is the radio link free from temporary disturbances? Examples:

– Regular temporary disturbances (e.g. center support or

mounting stand, with installation on a moving scraper
bridge)

– Irregular temporary disturbances (e.g. vehicles or persons

crossing the radio link)

4 Are the antennas of the MIQ/Blue PS modules free of water,

snow, ice?

5 When using a canopy:

Is the SSH/IQ plastic canopy used
(no metal or PVC canopy)?

6 Are the antennas in the original condition (e.g. no antenna ex-

tension cable)?
7 Was the range test carried out with attenuator?
8 With installation on a moving scraper bridge:

Was the range test carried out for a complete rotation of the

scraper bridge?
9 Is the distance between 2 MIQ/Blue PS masters (for several ra-

dio links) at least 50 m?
10 Is the distance between 2 MIQ/Blue PS slaveS (for several ra-

dio links) at least 2 m?

Radio link check list For safe operation of a radio link, check the system with the following

check list.
The following checklist supports you when planning, projecting and

installing a radio link with the MIQ/Blue PS radio modules.
For smooth operation, you should be able to answer all questions with
"Yes".

Note

Interferences are possible also with short radio links if the radio signal
is reflected by walls that are outside the direct radio link. Due to reflec­tions, radio signals may reach the receiver alleviated or several times.
In this case, changing the location of a MIQ/Blue PS module only
slightly can improve the transmission.

3.4 Installation in the IQ SENSORNET

The IQ SENSORNET provides a number of options for integrating the
MIQ/Blue PS mechanically and electrically in the system (stacked
mounting, distributed mounting, etc.). The individual types of installa­tion are described in detail in the I
operating manual.

Note

If there are several power supply modules in the IQ S
helpful if all the power supply modules are connected to a single power
supply. As a result, the system can be easily switched on and off from
a single location.

3.5 Electrical connections: General instructions

Cable glands All electric cables are fed into the enclosure of the MIQ/Blue PS from

below through prepared openings. Cable glands with different clamping
ranges are provided with the MIQ/Blue PS to provide sealing between
the cable and enclosure as well as for strain relief. Select the suitable
cable gland for the respective cable diameter:

 Small, clamping range 4.5 to 10 mm. This cable gland is suitable for

all IQ S

ENSOR NET cables.

 Large, clamping range 7 to 13 mm. This cable gland is required for

cable sheaths with an outer diameter of more than 10 mm and is
screwed into the enclosure via an extension piece.

Note

If necessary, you can order additional large cable glands as a set of 4
pieces (model EW/1, order number 480 051).

General installation

instructions

Observe the following points when attaching connecting wires to the
terminal strip:

 Shorten all the wires to be used to the length required for the instal-

lation

 Always fit all the ends of the wires with wire end sleeves before con-

necting them to the terminal strip

 Any wires that are not used and project into the enclosure must be

cut off as closely as possible to the cable gland.

 In each of the remaining free openings, screw in a small cable gland

with sealing ring and close them with a blind plug.

Warning

No free wires must be allowed to project into the enclosure. Oth­erwise, there is a danger that areas safe to contact could come
into contact with dangerous voltages. This could result in life
threatening electric shock when working with the IQ S
Always cut off any wires that are not in use as closely as possible
to the cable gland.

If no further 2,4 GHz radio links ("Pico nets", e. g. Bluetooth or WLan
devices) of other manufacturers operate in the same radio area, 10

7.3 Power supply

Several MIQ/Blue PS

modules on an

IQ S

ENSORNET island

Compatibility with other

line power supply units

Example Problem:

If several MIQ/Blue PS modules are positioned on one IQ S

ENSORNET

island, only one of them can take over the power supply. All other MIQ/
Blue PS modules count as consumers in the power rating (power
requirement 0.6 W). Accordingly, only one MIQ/Blue PS module has to
be connected to the power supply.

If other power supply modules (e.g. MIQ/PS) are installed on the
IQ S

ENSORNET island, the line power supply units of all MIQ/Blue PS

modules are automatically inactive. Connecting the MIQ/Blue PS line
power supply units to a power supply remains ineffective here. In this
case, all MIQ/Blue PS modules are consumers with a power consump­tion of 0.6 W each in the power rating.

 An IQ SENSORNET island should consist of the following compo-

nents plus two MIQ/Blue PS modules:

700 IQ 1.5

®

700 IQ 0.2
MIQ/CHV PLUS 1.0
MIQ/TC 2020 XT (docked from time to time) 3.0

 In this example, both MIQ/Blue PS modules and the MIQ/CHV

PLUS should be mounted as a stack.

 The IQ S

ENSORNET system should be supplied with 100 ...

240 V AC.

Solution/proceeding:
 An MIQ/Blue PS module counts as a consumer with 0.6 W. In the

worst case, i. e. with a docked MIQ/TC 2020 XT, the power require­ment of all components is 7.8 W. Power losses in cables do not have
to be taken into account due to the stack mounting.

 Power rating: The calculated power requirement is greater than the

maximum power delivery of the MIQ/Blue PS line power supply unit.
Therefore, an additional power supply module has to be installed
(e.g. MIQ/PS).

 New power rating: The second MIQ/Blue PS module has to be taken

into account as a consumer as well. Therefore, the power consump­tion is now 8.4 W. With an MIQ/PS power supply module (18 W),
there is still an energy reserve of 9.6 W for any future extensions.
