1.2 The IQ SENSOR NET system 2020 XT USB

1.2.1 Structure of the system

The IQ S

ENSOR NET is a modular measuring system for online analysis.

Modular means that the essential functional units of the measuring system are distributed in components that can be individually compiled for special applications.

The essential functional units of the IQ S

ENSOR NET

system 2020 XT USB include:

 Terminal/controller

 IQ sensors

 Inputs (current inputs)

 Outputs (relay contacts, current outputs, valve outputs)

 Additional terminals (mobile terminals, software terminal)

 Help functions (e.g. power supply unit).

System communication The functional units are connected with one another via a common line

(Fig. 1-2). The line consists of two wires and a shield. It transports digital information between the controller and the other modules. At the same time, the line is used to supply all modules with electrical voltage from a power supply unit. The power supply unit is only required for the power supply and is not used in the system communication.

System 2020 XT USB Overview

Each main measured value occupies a sensor location in the IQ S

ENSOR NET. A double sensor with two active main measured

values thus occupies two sensor locations. The available sensor locations can be occupied by any single or double sensors.

1.2.4 Components of the system 2020 XT USB

Minimum configuration

(basic components)

IQ sensors, main and

secondary measured

values

The following basic components are required for a 2020 XT USB system:

 An MIQ/TC 2020 XT, configured as controller

 A power supply module (e.g. MIQ/PS)

 At least one IQ sensor.

Sensors provide main measured values (e.g. pH, D. O. concentration, turbidity value...) and additionally, depending on the type, secondary measured values (e.g. temperature). In the System 2020 XT USB, digital YSI single sensors and double sensors can be used:

 Single sensors provide a main measured value and normally a

secondary measured value (example: TriOxmatic 700 IQ

→ D. O. +

temperature).

 All active 0/4-20 mA inputs of the MIQ/IC2 input module rank among

the single sensors. Via a 0/4-20 mA input, any external instruments can be connected to the IQ S

ENSOR NET via their current output.

Each input provides a main measured value.

 Double sensors provide up to two main measured values and

normally a secondary measured value (example: VARiON 700 IQ

→ ammonium + nitrate + temperature).

Extension components The system can be adapted to fulfill different specifications by adding

further components, e.g. by:

 Terminals. They are the operation and communication units for the

IQ S

ENSOR NET. Available are:

– MIQ/TC 2020 XT for operation of the system from various

locations, e.g. calibration of IQ sensors on site (compatible terminals, see section 1.4)

– MIQ/T2020 PC software terminals. The connection to the PC can

be established with the MIQ/IF232 interface module and the RS 232 interface of the PC or a remote connection with a modem (set for radio transmission, see chapter 10).

 Output modules with relay, current and valve outputs. Valve outputs

enable the time controlled, compressed air operated cleaning of the sensor.

Page 14

Overview System 2020 XT USB

Each current output, relay output and valve output occupies an output channel in the IQ S

ENSOR NET. The available output

channels can be assigned to outputs arbitrarily.

 Power supply modules for power supply

 MIQ/JB and MIQ/JBR branching modules to branch the system and

to connect IQ sensors and terminals

 MIQ/Blue PS radio modules for wireless connection within the

ENSOR NET.

Connecting

MIQ modules

There are two basic mounting variants for connecting the MIQ modules:

 Stack mounting - permanent mechanical and

electrical connection. The housings of the MIQ modules are permanently mounted on one another to form a stack. No cabling is necessary.

 Distributed mounting - electrical connection via cable.

Locally separated MIQ modules or module stacks are connected with one another via the SNCIQ or SNCIQ/UG cable.

The following diagram shows an IQ S

ENSOR NET system with two

mounting variants (Fig. 1-3).

ba76019e01 12/2012

Fig. 1-3 Example of an IQ SENSOR NET system configuration

IQ sensors Up to 20 IQ sensors of any type can be used in the system

2020 XT USB. They can be connected to any MIQ module that has a free connection for the IQ S

ENSOR NET. The connection between the

IQ sensor and MIQ module is made via the SACIQ sensor connection cable. The IQ sensor connection cable is connected with the plug head connector of the IQ sensor via a screwable socket to form a watertight connection. As a result, the IQ sensor can be quickly removed for maintenance activities and then connected again.

1.2.5 MIQ modules

Some of the IQ S

ENSOR NET components are so-called MIQ modules

with different functions.

All MIQ modules have a standard housing with the following features (Fig. 1-4):

ba76019e01 12/2012

Page 17

System 2020 XT USB Overview

Common characteristics

of the MIQ modules

 Module lid with hinge

Due to its wide opening angle, the lid provides a large space for working inside the module (e.g. for connecting lines to the terminal strip).

 Docking facility

MIQ modules can be mechanically docked onto one another. As a result, several MIQ modules can be mounted in the form of a stack to create a single unit (stack mounting). At the same time, docking enables the MIQ modules to be electrically connected with one another via the module contacts on the front and back so that no cabling is required. Even when it is part of a stack, each MIQ module can be opened. In addition, a terminal component can be docked onto each free lid front.

 Terminal strip

Further IQ S

ENSOR NET components can be connected by cable to

the terminal strip inside the housing (distributed mounting). The terminal strip enables IQ sensors to be connected via the SACIQ sensor connection cable or the IQ S

ENSOR NET can be further

branched and extended here. Certain MIQ modules have a terminal strip with further specific connections (e.g. power connection, relay contacts, current outputs).

 Local identity function

The local identity function is integrated in each MIQ module in the form of a memory chip. This memory chip can store information such as the designation of the measurement location and a specific selection of IQ sensors for the measured value display. This information is output when a terminal is docked and, thus, e.g. enables the rapid finding of local IQ sensors for calibration.

 Voltage diagnosis via LEDs

Two LEDs, yellow and red, on the side of the housing are used to monitor the operational voltage of each MIQ module.

1.3.1 Operation as terminal/controller

When configured as a controller, the MIQ/TC 2020 XT is a basic component of the 2020 XT USB system and must therefore permanently remain in the system.

The MIQ/TC 2020 XT is connected to the system by docking on the free front cover of an MIQ module.

The controller function takes over the following tasks:

 Control and monitoring of all IQ sensors

 Control and monitoring of all current and relay outputs

 Continuous diagnosis of the system, i.e. recording the information

and error messages of all modules and entering them in the system log book (e.g.: voltage monitoring)

 Recording measured data in the fixed interval

 Communication with external digital interfaces such as

– USB memory device

– Modem

– PROFIBUS, Modbus, RS485

–PC

Overview System 2020 XT USB

A terminal is required to display and set up the functions of the controller. The following terminal components are suitable:

 MIQ/TC 2020 XT configured as terminal/controller or as terminal

(compatible terminals, see section 1.4)

 MIQ/T2020 PC

(with MIQ/IF232 interface module, PC, modem connection or PROFIBUS environment).

The present component operating manual of the IQ S

ENSOR NET

System 2020 XT USB includes all functions of the MIQ/TC 2020 XT. The connection to Profibus or Modbus is established with the MIQ/(A-)PR and MIQ/(A-)MOD extension modules.

1.3.2 Operation as a terminal

The MIQ/TC 2020 XT configured as a terminal is an extension component for the IQ S

ENSOR NET System. The MIQ/TC 2020 XT can

be used as a mobile control unit and docked on and removed from all free front covers of MIQ modules. The docking is simply done by hand, without using any tools.

The terminal function is the graphical user interface of the system. It is used for the following purposes:

 Display of measured values

 Setting of IQ sensors, outputs, terminal characteristics, date, time,

etc.

 Execution of maintenance and calibration work

 Display of calibration data

1 - 14

 Display of components lists (IQ sensors and outputs)

 Display of the log book entries

If the MIQ/TC 2020 XT is registered in the system as a terminal, it is mobile and can be removed at any time. If the main controller of the system fails, the MIQ/TC 2020 XT automatically assumes the job of the failed controller (see section 1.3.3).

System 2020 XT USB Overview

1.3.3 Operation as backup controller

Automatic backup

function

If the MIQ/TC 2020 XT is configured as a terminal, it has a backup controller that assumes the basic functions of the IQ S

ENSOR NET

controller in the case of its failure. Thus the operating safety of the system is considerably increased. For these purposes the MIQ/ TC 2020 XT regularly and automatically saves the system configuration during the normal terminal operation.

System configuration The system configuration incudes the following allocations and

settings:

 Settings of sensors and diff. sensors

 Settings of outputs and links

 Edit list of sensors

 Edit list of outputs

 Measured value recording (datalogger settings)

 List of all components including software versions but without

terminal information.

 Application-related sensor calibration (e.g. matrix adjustment)

In the IQ S

ENSOR NET, the system configuration is stored in the

controller (MIQ/TC 2020 XT).

1.4.3 Availability of the system

As a basic principle, the IQ S

ENSOR NET offers a very high availability.

This is achieved by

 The two-wire connection technique that is not interference-prone

 The digital signal transmission resulting from this

 Tools for error diagnosis

– LEDs on the MIQ modules to check the available voltage

– Log book messages with instructions to eliminate problems

 The possibility to simply assign substitute components for

components to be exchanged. Replacing components is simple and can be performed very quickly (see section 7.4). The system configuration (Settings of sensors and diff. sensors and Settings of outputs and links) and the measured data are stored in the controller and remain stored when other components are used.

Preventive actions to

optimize the availability

of the system

If the requirements of the availability are especially high, you can further improve the availability of the system as follows:

 Install identical components in the system.

If the requirements of the availability are high, components can be installed doubly in the system (exception: controller component).

 Back up the controller function with the aid of a second MIQ/

TC 2020 XT configured as a terminal. The MIQ/TC 2020 XT has a redundant controller function. It maintains all essential functions of the system in the case of a controller malfunction and saves all settings. The controller operation starts automatically.

 Keep substitute components ready.

The system automatically recognizes substitute components of active components (IQ sensors and the output modules). They are easily integrated in the system by assigning them as substitute components.

 Save the system configuration.

The system configuration (Settings of sensors and diff. sensors and Settings of outputs and links) can be saved on a PC. Transmission takes place via the USB interface (alternative options: see section

1.2.3). The stored system configuration can be loaded from the PC on a substitute controller if necessary.

3.4 Basic requirements for optimum installation

3.4.1 General information

The IQ S

ENSOR NET supplies all components with low voltage as well

as digital communication via a shielded 2-wire line.

Due to this characteristic, the following factors must be taken into account in the planning of an IQ S

ENSOR NET system:

 Power consumption of all components (power rating). Primarily, this

determines the number of power supply modules required (section

3.4.2).

 Distance of the components from one another. Large distances may

require a further MIQ/PS power supply module and/or an MIQ/JBR signal amplifier module (section 3.4.3).

 Placement of the MIQ/PS power supply modules in the

IQ S

ENSOR NET (effect on the power supply - section 3.4.3).

Caution

Only IQ SENSOR NET products may be used in the IQ SENSOR NET.

3.4.2 Drawing up the power rating

Power rating - why? All components in the system require a specific level of electrical power

for operation. Thus, it is necessary to draw up a power rating after selecting all the components. At the same time, this can determine whether the entire power requirement of all components (consumers) is covered by the existing MIQ power supply modules. If this is not the case, the power available in the system must be increased by further MIQ power supply modules.

ba76019e01 12/2012

Note

The power rating provides an initial guide value. In specific limiting cases, the power supply may be insufficient despite the positive power rating. Long cable lines, for example, result in additional power losses that may have to be compensated by further MIQ power supply modules. This can be checked for the planned installation by following section 3.4.3.

The total power requirement P of all consumers can be determined from the following table:

4 Evaluation:

If the point is in the lower, valid range, no additional power supply module is required.

If the point is in the upper, invalid range, an additional power supply module is required. Install this power supply module in the vicinity of the main consumers of this section, or, if not possible, - starting from the primary MIQ power supply module

- approx. at that point of the section where the maximum cable length is exceeded (see following example).

Example Problem:

Consumers with a total power requirement of 9 W are positioned on a cable section of 650 m. Is the power supply with one power supply module sufficient? At which point must a further power supply module be installed if necessary?

Proceeding:

 Enter both values as a point in the diagram (point "x" in Fig. 3-3).

 Result: the point is in the invalid range. I. e. the power supply is not

sufficient.

 Draw down a vertical line from the point until the line crosses the limit

between the upper and lower range. The intersecting point specifies the maximum cable length for the existing power requirement (at approx. 470 m). This is the place where the additional power supply module is required.

 If any main consumers are near the place, the power supply module

should be installed in their vicinity (ideally, directly on them).

After commissioning, you can check the voltage directly on the MIQ modules or on the terminal connections of the IQ sensors (see section 7.2.2). The limits of the voltage levels are given in section

If the sum of all line lengths (including the SACIQ sensor connection cable) exceeds 1000 m, an MIQ/JBR signal amplifier module must be installed in the system. More details of this are given in the MIQ/JBR component operating manual.

3.4.4 Optimum installation of MIQ power supply modules

Basic rules  Install the MIQ power supply modules as near as possible to the

ENSOR NET components with the highest power consumption.

IQ S This also applies in the case of several MIQ power supply modules in the system.

 If possible, assemble the IQ S

ENSOR NET in a star configuration from

the MIQ power supply modules.

3.4.5 Installation guidelines for lightning protection

When using the IQ S

ENSOR NET measuring technique, particularly in

outdoor areas, adequate protection against (electrical) surges must be provided. A surge is a summation phenomenon of surge voltage and surge current. It is generated through the indirect effect of a lightning event or switching operation in the mains, in the grounding system and in information technology lines.

To be adequately protected against the damaging effects of surges, an integrated concept of the following protective measures is required:

 technical protective measures inside the instrument, and

 exterior protective measures of the installation environment.

With YSI online measuring technique, the technical protective measures inside the instrument are already integrated as the so-called lightning protection (see chapter 8 T

ECHNICAL DATA).

The exterior protective measures of the installation environment can be carried out observing the following guidelines:

1 All lines of IQ S

ENSOR NET systems must be

a) installed inside (or else close to) the grounded metallic mounting constructions, e.g. handrails, pipes and posts if possible b) or, particularly in the case of longer lines, laid in the ground.

Background: the small distance from the grounded metal construction or the installation in the ground prevents the development of induction loops between the cable and the ground hazardous in the case of lightning strikes.

3 - 10

ba76019e01 12/2012

Page 41

System 2020 XT USB Installation

2 The SNCIQ or SNCIQ-UG cable material must be used exclusively.

This cable material, particularly the high line cross section of the cable shielding (1.5 mm²), is an important prerequisite for the hazard-free discharging of the surge without inadmissibly high overvoltages developing along the line at the same time that could have a damaging effect on the individual IQ S

ENSOR NET

components. We strongly recommend not to use any other cables, which normally have a considerably lower shielding wire crosssection.

3 All metallic mounting constructions, handrails, pipes, posts etc. on

which MIQ modules are installed must be connected to the local potential equalization system and the grounding system or must be individually sufficiently grounded locally according to the codes of practice. For the individual grounding of the measuring point the mounting construction must be solidly connected by means of a large-area auxiliary electrode with the measuring medium. Metallic control shafts/pipes and other large-area metallic bodies that reach into the measuring medium are, for example, ideal for use in the grounding of the mounting construction. This creates a set path for the main surge. As a result it is possible to avoid the surge being discharged via the IQ IQ S

ENSOR NET cable

and via the valuable sensors in the measuring medium.

4 The contacts of the MIQ modules always have to be protected with

the respective contact covers when they are not used by terminal components. The contact covers improve the insulation against electric fields of a thunderstorm by enlarging air gaps and creepage distances.

5 We recommend to install a metal or nonmetal sun shield at each

open air location of MIQ modules. Sun shields protect the electric field lines in the area of the MIQ module through an advantageous development of the electrical field lines in the area of the MIQ module and promote the dissipation of the surge via the mounting construction.

6 The line voltage that supports the measuring system must

correspond to overvoltage category II. Normally this is ensured by the public operators of the supply network systems. In companyowned networks, e.g. in all power supply systems owned by wastewater treatment plants, this must be kept separate by a potential equalization and asurge protection system for the plant.

ba76019e01 12/2012

3 - 11

Page 42

Installation System 2020 XT USB

7 The IQ SENSOR NET safety and lightning protection concept is partly

based on the high-quality protective insulation of the line power supply units and the total system. It does not have or require any protective ground (PG) conductor or earth terminal. Avoid any direct connection of the IQ S

ENSOR NET connections or the metallic sensor

enclosures with the local grounding or potential equalization system and with metallic construction elements (see point 9).

8 Additional external lightning protection measures directly on the

ENSOR NET system or its components, e.g. the use of

IQ S overvoltage surge arresters, are not necessary for protection against the indirect effects of lightning and could possibly result in malfunctions.

9 For the realisation of the internal lightning protection of the system

(e.g. wastewater treatment plant control stands) and for the protection of IQ S into buildings or distributions coming from the IQ S

ENSOR NET external resources, cable entry points

ENSOR NET must

be carried out as follows:

– The shield of SNCIQ or SNCIQ-UG cables can be connected to

the local potential equalization with a gas overvoltage surge arrester. Use shielding terminals for the contacting of the shield (e.g. those of the PROFIBUS-System). The shield of the cable must not be opened under any circumstances.

– 0/4-20 mA interfaces must be realized with shielded cables. The

cable shield must be connected directly to the potential equalization(s) provided. If plant potential equalization systems are provided on both sides, the shield must also be connected on both sides. The inner conductors must have no contact with the potential equalization.

– PROFIBUS cables and Modbus cables have to be installed

according to the prescriptions of the respective bus system.

– Relay lines should be connected to the local potential

equalization in order to provide general and consistent protection via gas overvoltage surge arresters.

3.5 Connecting system components

3.5.1 General information

The IQ S

ENSOR NET system components are connected to form a

functioning unit in the following ways:

 Stacked mounting of MIQ modules

Up to three MIQ modules can be installed and mechanically connected with one another to form a stack at a single location. The contacts on the front and rear automatically create the electrical connection between the MIQ modules in the stack (section 3.5.2).

 Distributed mounting of MIQ modules

Individual MIQ modules or an assembled module stack are installed at various locations (for example, a central control unit and an MIQ branching module for connecting IQ sensors at the edge of the basin). The spatial distance is bridged with the aid of the SNCIQ or SNCIQ/UG cable (section 3.5.3).

 Connection of IQ sensors:

IQ sensors are connected to an MIQ module with the aid of the SACIQ cable. This cable is available in different lengths. The MIQ module must have a free SENSORNET connection on the terminal strip. On the sensor side, the connection is made via a plug that is standard for all IQ sensors (section 3.5.4).

 Docking of a terminal unit:

A terminal unit is attached to the lid of a free MIQ module with the aid of a quick-release locking mechanism (section 3.5.5).

Caution

Distributed mounting is only allowed in a star configuration. The system must nowhere be closed to form a ring. Only use the assembly material provided for the installation.

ba76019e01 12/2012

3 - 13

Page 44

Installation System 2020 XT USB

3.5.2 Stacked mounting of MIQ modules:

Caution

For optimum stability, a maximum of three MIQ modules can be mounted in any one stack. Only one MIQ power supply module may be mounted per module stack.

Mounting direction MIQ modules can be stacked on top of one another from both sides. All

the required installation materials are contained in the scope of delivery of the MIQ modules.

Variant 1 - stack expansion forwards.

The back of an MIQ module is attached to the lid of another MIQ module (page 3-15).

Variant 2: - stack expansion backwards.

The lid of an MIQ module is attached to the back of another MIQ module (page 3-18).

Which variant is suitable for a specific case depends on whether and how an MIQ module is already permanently installed at a location (e.g. on a wall or in a panel), among other factors.

Note

In the case of panel mounting, the front MIQ module can only be installed individually in the switch cabinet aperture. Only then can further MIQ modules be added to its back (variant 2). If necessary, dismantle the front MIQ module from an already mounted stack before mounting.

Materials required  2 x ISO blind nuts M4

 2 x cheese-head screws M4x16 with plastic washer

Differentiating

IQ sensors of the same

type in the system

For the simpler correlation of measured value and measurement location, the system provides the option of giving each IQ sensor a user-defined name (see section 5.5.1). This name appears in the measured value display.

When the IQ sensor is delivered, the name is identical with the serial number. Therefore, after the initial commissioning, IQ sensors of the same type can only be differentiated by the serial number that appears on the measured value display. In order to prevent confusing the IQ sensors when assigning the name, you can proceed according to one of the two methods:

 Note the serial number of the IQ sensor at the respective

measurement location before installation. Then, install all IQ sensors. After the commissioning, open the list of sensors on the controller. Then assign a suitable sensor name using the sensor type and the noted serial number.

CCESSORIES AND

Connecting the SACIQ

cable to the MIQ module

 Disconnect the IQ sensors of the same type from the connection

cables before commissioning the system. Then, put the system into operation. After the commissioning, connect the IQ sensors individually to the SACIQ connection cable. To do so, proceed stepby-step sensor for sensor. After each newly connected IQ sensor, select the Edit list of sensors menu on the terminal and assign a suitable sensor name to the sensor.

Note

The list of sensors and the assignment of sensor names is described in section 5.5.1 on page 5-12.

The connection of the SACIQ cable to the terminal strip of an MIQ module is described in section 3.5.3 (see C

3.6 Installation of the MIQ modules at the installation location

3.6.1 General information

The IQ S

ENSOR NET system has a comprehensive program of

mounting accessories, which can be used to adapt the installation to the most varied requirements.

Caution

MIQ modules installed outside must always be protected by a sun shield against the effects of the weather (snow, ice and direct solar radiation). Otherwise, malfunctions can result. Always mount MIQ modules vertically. Do not under any circumstances install MIQ modules without rain protection with the lid facing upwards (danger of retained humidity and penetration of moisture).

Installation options The most important types of installation for MIQ modules and module

stacks are described in the following chapters:

 Mounting on a mounting stand with the SSH/IQ sun shield:

The SSH/IQ sun shield provides enough space for one unit of up to three stacked MIQ modules and a docked terminal (section 3.6.2).

 Mounting on the SD/K 170 sun shield

The SD/K 170 sun shield provides enough space for a single MIQ module with a docked terminal. The sun shield can be mounted on round or square section pipes (e.g. rails) with the aid of the MR/ SD 170 mounting kit (section 3.6.3).

 Wall mounting:

The back MIQ module of a module stack or a single MIQ module is permanently screwed to a wall. For wall mounting, use the WMS/IQ mounting set (see chapter 10 A

CCESSORIES AND OPTIONS).

 Panel mounting:

The front MIQ module of a module stack or a single MIQ module is installed in the aperture of a panel. The aperture dimensions are 138 x 138 mm + 1 mm (maximum thickness 15 mm) according to DIN 43700 or IEC 473 (section 3.6.4).

 Top hat rail mounting:

The back MIQ module of a module stack or a single MIQ module is mounted on a 35 mm top hat rail with the aid of a bracket in accordance with EN 50022, e.g. in a control cabinet. The connection can be released again with one simple movement (section 3.6.5).

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

installation

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

connecting them to the terminal strip

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

off as closely as possible to the cable gland.

 Screw a small cable gland with sealing ring into each remaining free

opening and close it 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.

modules (Fig. 3-32):

– Yellow lights up Operational voltage OK.

The operational voltage supplied is constant and is max. 24 V.

– Red lights up Operational voltage with power

limitation. The operational voltage supplied is adjusted to the load conditions.

– no LED lights up: Operational voltage too low.

The operational voltage supplied is too low or the MIQ power supply module is defective.

2 Dock any existing mobile terminals on the system as far away

as possible from a MIQ power supply module (i.e. test of the power supply in the most unfavorable possible conditions)

3 Check the status of the LEDs on all MIQ modules (except for

the MIQ power supply modules, see step 1) (Fig. 3-32):

– Yellow lights up Operational voltage OK

– Red lights up Operational voltage in warning

range. The component is fully functional. However, any further slight drop in voltage can lead to failure

3.10 System extension and modification

3.10.1 General information

The modular structure of the IQ S

ENSOR NET system makes it easy to

carry out subsequent extensions and modifications. The system automatically identifies new active modules and includes them in the list of modules. Added IQ sensors immediately deliver measured values without the necessity for special settings.

Warning

When the system is switched on, if the MIQ/PS power supply module is opened, there is a danger to life due to possible hazard of electric shock from line voltage. There is also a danger to life inside the relay output modules (e.g. MIQ/ CR3) if voltages are applied to the relay contacts that may present a hazard of electric shock. Before opening the MIQ modules, switch off the system and all external voltages that present a hazard of electric shock and secure the system against being inadvertently switched on again.

Installation instructions Note the following points in any system extension or modification:

 Before any extension or modification, check that the planned

number of MIQ power supply modules is sufficient for the planned installation (see section 3.3 S

 Before beginning the installation tasks, always switch off the system.

Also, switch off all external voltages

YSTEM PLANNING)

Installing new

components

 Clean the MIQ module stack to remove the worst of any dirt before

taking it apart or opening it (see section 6.2 C

LEANING)

 Before mounting the stack, check the contacts on the front and back

of any MIQ modules that were already in use somewhere else. Clean any dirty contacts

 After any change to the system, check the setting of the SN

terminator switches and adjust it if necessary (see section

3.9.1 T

Install new components as described in section 3.5 C

SYSTEM COMPONENTS. Then put the system into operation again

(section 3.9 C

OPOLOGY AND TERMINATOR SWITCH).

Page 78

Installation System 2020 XT USB

Note

If a new component is not included, the maximum number of datasets (active and inactive datasets) may be exceeded.

The maximum number of datasets for IQ sensors is 20. For MIQ output modules, the maximum number of datasets (active and inactive datasets) is 8.

When this number of datasets is already stored, no further component can be installed.

If necessary, an inactive dataset has to be erased to make an extension possible (how to erase inactive datasets is described in section 5.5.3 or section 5.8.2).

Note

New modules are first registered on the system when the measured value display is opened.

Replacing components The replacement of components is described in detail in section

7.4 R

EPLACING SYSTEM COMPONENTS.

3.11 Configuration of the MIQ/TC 2020 XT as a terminal/ controller or terminal

During the initial commissioning of the MIQ/TC 2020 XT a query appears asking whether the MIQ/TC 2020 XT should work as a terminal/controller or just as a terminal. Select the required function for each MIQ/TC 2020 XT.

The MIQ/TC 2020 XT will then try to register with the selected functionality on the IQ S be active in an IQ S

When the MIQ/TC 2020 XT is once configured, the MIQ/TC 2020 XT saves this configuration. Thus, no further query appears during the docking on and off of terminals.

(more compatible terminals, see section 1.4)

ENSOR NET.

 MIQ/IF232 interface component with software terminal (see MIQ/

IF232 component operating manual)

The terminal can be used to:

 Display measurement results

 Start calibration

 Perform system and terminal settings

 Display messages.

Note

To guarantee data safety within the IQ S

ENSOR NET, access to the

following functions is only possible from one terminal at the same time:

 Opening the Settings menu

 Start calibration

 Assigning IQ sensors or MIQ output modules as substitutes.

If one of these functions is already active at another terminal, a note appears on the display.

4.5 Messages and log book

The IQ SENSOR NET continuously monitors the status of the entire system. If the IQ S appears. New messages can be recognized by the flashing information symbol or error symbol on the display.

All messages are recorded in the log book.

In addition, a flashing status LED at the MIQ/TC 2020 XT reminds you that there is an error or alarm (see section 1.3.5).

4.5.1 Message types

The system differentiates two types of messages:

ENSOR NET identifies system changes, a message

 Errors

Indicates a critical status in the system or an individual system component that requires immediate action. In the case of new error messages, the error symbol flashes on the display.

 Information

Information that does not require immediate action. In the case of new information, the info symbol flashes on the display.

Note

In the case of errors, immediately open the detailed message text in the log book and perform the recommended actions. If the actions have been performed, mark the message as read (see section 4.5.3).

4.5.2 Log book

The log book is a list with all the messages from all modules. The log book contains up to 1000 entries. If there are more than 1000 messages, the oldest entries are deleted.

4 - 20

New messages can be recognized by the flashing information symbol or error symbol. The log book always contains the latest message in the first position. They do not yet have a checkmark in the status field.

The flashing of the info or error symbol only stops after all detailed message texts in the log book have been opened and marked with a checkmark (✔) (see section 4.5.3).
