System 182 Overview

IQ Sensors, digital

Universal Transmitter

DIQ/S 182-PR

1Overview

1.1 Structure and function

The System 182 is a modular, multiparameter measuring system. The control and operation unit of the system is the DIQ/S 182-PR Universal Transmitter with integrated power pack. Is has three relay outputs and a PROFIBUS-DP output for the connection to existing process control systems.

Sensors One or two digital YSI single sensors (one sensor for one main

measured parameter) or a double sensor (one sensor for two main measured parameters) can be connected to the DIQ/S 182-PR Universal Transmitter. I. e. up to two main measured parameters (e.g. pH, D. O. content, turbidity value...) and additionally up to two secondary measured parameters (e.g. temperature) can be displayed and administrated. Each sensor is automatically recognized after being connected and immediately starts measuring.

The sensors can be directly connected to the DIQ/S 182-PR Universal Transmitter.

Overview System 182

Relay outputs The relay outputs can be linked to sensors. Linked outputs can be used

to monitor sensors and for the output of measured values.

A relay output is programmable as:

 Alarm contact (event monitoring)

 Limit monitor

 Proportional output of measured values (pulse width or frequency

output)

 Control unit of a compressed air-driven sensor cleaning system.

For quick orientation, the states of all relay outputs are clearly indicated on the display.

PROFIBUS DP output The PROFIBUS output enables a connection to a PROFIBUS master

(PROFIBUS-DP) and thus a connection to a superordinate process control.

Compressed air-driven

cleaning system

The DIQ/S 182-PR Universal Transmitter is prepared for the compressed air-driven, time-controlled sensor cleaning function. For this, a DIQ/CHV valve module and if necessary a CH cleaning head is required per sensor (both available as accessories). The cleaning procedure is controlled by the Universal Transmitter. The Universal Transmitter provides the supply voltage and control relay for the compressed air valve in the DIQ/CHV valve module. This enables a simple setup and uncomplicated wiring.

Alternatively, the MIQ/CHV PLUS valve module can be installed in the system. It combines the relay, valve and valve power supply in one MIQ enclosure. Thus, no additional wiring is required, which makes installation easier especially if the distance between the Universal Transmitter and sensor is great.

Further system options If necessary, an additional power pack can be added to supply sensors

with high power consumption (e.g. UV/VIS sensor).

 Operating manual.

3.2 Requirements of the measurement location

The measurement location must meet the environmental conditions specified in section 10.1 DIQ/S 182-PR.

3.3 Installation guidelines for lightning protection

When using the IQ SENSOR NET instrumentation, 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:

 internal device-related protective measures and

ba76024e01 02/2012

 external protective measures of the installation environment.

The internal device-related protective measures are already integrated in the YSI online measuring technology as so-called 'lightning protection' (see chapter 10 T

ECHNICAL DATA).

3 - 1

Installation System 182

The external protective measures of the installation environment can be carried out with respect to the following guidelines:

1 All lines of the IQ S

ENSOR NET system 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 formation of highly lightning hazardous inductive loops between the cables and ground is avoided through the low clearance of the grounded metal construction or by installation in the ground.

2 Only the SNCIQ or SNCIQ-UG cable material must be used. 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. It is

not recommended to use cables from other manufacturers with usually appreciably lower shielding conductor cross sections.

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 S

ENSOR NET cable

and via the valuable sensors in the measuring medium.

3 - 2

4 The contacts of the MIQ modules must always be protected by the

associated contact covers if they are not in use. The contact cover provides improved insulation against the electric fields of a thunderstorm event through the extension of the air and creepage paths.

5 It is recommended to attach a metallic or nonmetallic sun shield to

each outside location of the 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 mains voltage for supplying the measuring system must comply

ba76024e01 02/2012

System 182 Installation

with overvoltage category II. Generally this is ensured through the

public operator of the power supply networks. In company-owned

networks, e.g. in all power supply systems owned by wastewater

treatment plants, this must be kept separate by a potential

equalization and a surge protection system for the plant.

7 One part of the IQ S

ENSOR NET safety and lightning protection

concept is based on high-grade protective insulation of the network

components and of the entire 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

IQ S

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

overvoltage surge arresters, are not necessary for protection

against the indirect effects of lightning and could possibly result in

malfunctions.

9 For the realization 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. Shielding terminals (e. g. of the PROFIBUS system) have to be used to contact the shield. 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.

– The PROFIBUS cables have to be installed according to the rules

of the relevant 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 On site mounting of the Universal Transmitter and

MIQ Modules

3.5.1 General information

The DIQ/S 182-PR and the DIQ and MIQ modules have a comprehensive program of mounting accessories, which can be used to adapt the installation to the most varied requirements.

Caution

Components 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 the Universal Transmitter in an upright position. Do not under any circumstances install MIQ modules without rain protection with the lid facing upwards (danger of retained humidity and penetration of moisture).

Caution

No contact base may be mounted on the back of the module (danger of short-circuit!) if the module is mounted on a wall, a sun shield, or a top hat rail.

Installation options The most important types of installation for the Universal Transmitter

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 the Universal Transmitter and two MIQ modules (section 3.5.2).

 Wall mounting:

The Universal Transmitter or MIQ module is permanently screwed to a wall. For wall mounting, use the WMS/IQ mounting set (see chapter 12 A

CCESSORIES AND OPTIONS).

 Panel mounting:

The Universal Transmitter or MIQ module is installed in the aperture of a panel (section 3.5.3).

 Top hat rail mounting:

The Universal Transmitter or MIQ module is mounted on a 35 mm top hat rail with the aid of a bracket, e.g. in a control cabinet. The connection can be released again with one simple movement (section 3.5.4).

The following chapters describe the mounting of the Universal Transmitter. MIQ modules are mounted in the same way.

The various application possibilities of the DIQ modules are shown by means of examples in section 3.11.

3.6.1 DIQ/JB

The DIQ/JB module is a passive branching module and can be used for the following purposes

 To extend the SACIQ sensor connection cable, e.g. to connect a

sensor that is located farther away to the Universal Transmitter.

 To branch a line at the end of an extension.

Fig. 3-22 DIQ/JB open.

The DIQ/JB module has seven potential free terminals. To extend or branch lines, connect the three IQ S

ENSOR NET wires to each other

one-to-one at any terminals

 green <-> green

 red <-> red

 black/filler stranded wire <-> black/filler stranded wire.

3.6.2 DIQ/CHV

The DIQ/CHV module is a valve module for the automatic relaycontrolled compressed air-driven cleaning function in the 182 system. It provides four additional potential free terminals to branch (extend) interface lines. For each sensor that is to have compressed air cleaning a DIQ/CHV is required.

instructions

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

 Shorten all 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 enclosure 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 DIQ/S 182-PR. Always cut off any wires that are not in use as closely as possible to the cable gland.

3.9 Connections to the relay outputs

3.9.1 General installation instructions

Warning

If external electrical circuits that are subject to the danger of physical contact are incorrectly connected to the relay contacts, there may be a danger of life threatening electric shock. Electrical circuits are regarded to be subject to the danger of physical contact when there are voltages higher than the Safety Extra Low Voltage (SELV).

Pay attention to the following points during installation:  Electrical circuits subject to the danger of physical contact

must only be connected by a qualified electrician.

 Electrical circuits subject to the danger of physical contact

must only be connected when they are voltage-free.

 If electrical circuits subject to the danger of physical contact

are switched with a relay, no circuit that is not subject to this danger (e. g. the DIQ/CHV module) may be operated on the further relays.

 Switching voltages and switching currents on the relay

contacts must not exceed the values specified in chapter 10 T currents that are too high with an electrical fuse.

 Only single-phase consumers can be switched with the relays.

Under no circumstances must multiphase consumers be switched with the aid of several relays (example three-phase current driven pumps). Always switch multiphase consumers via a protective relay.

 After the Universal Transmitter has been installed, it may only

be opened if all external voltages have been switched off beforehand.

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 Universal Transmitter. Always cut off any wires that are not in use as closely as possible to the cable gland.

17 Close the enclosure of the Universal Transmitter.

3.9.2 Usage of the auxiliary voltage

The Universal Transmitter has a 24 V output (designation, HILFSSPANNUNG or AUXILIARY VOLTAGE on the terminal strip). You can use this auxiliary voltage for the relay-controlled opening of the valve in a DIQ/CHV valve module for the compressed air-driven sensor cleaning function. To do so, you have to connect the auxiliary voltage output, a free relay contact and the valve connection in the DIQ/CHV in series. Bridge a terminal of the auxiliary voltage output with a terminal of a relay output and run a control line from the remaining terminals to the valve module.

Caution

The auxiliary voltage must not be used for other purposes.

6.3 Basic information on relay functions

In this chapter, you will find general basic information concerning the following relay functions:

 Event monitoring (see section 6.3.1)

 Limit indicator (see section 6.3.2)

 Proportional output (see section 6.3.3)

6.3.1 Event monitoring

When using a relay for event monitoring, a relay action (Open, Close) occurs when the monitored event takes place.

This function is suitable, e.g. for the monitoring of errors in the system. If an event takes place, the relay works as an alarm contact.

Note

For monitoring functions, use the relay preferably as an opener. In the case of an error, the relay opens. As a result, the monitoring function operates even if, e.g. the supply voltage fails.

6.3.2 Limit indicator

With a limit indicator, a relay switches when a specified limiting value is exceeded or undercut.

Limit indicators can be used in the following way:

 Monitoring a limiting value using a relay:

when a limiting value (upper or lower limiting value) is exceeded or

undercut, a relay switches. The Open or Close relay actions are

possible in each case (see page 6-6).

 Monitoring two limiting values using two relays:

If the upper limiting value is exceeded or undercut, a relay switches,

and if the lower limiting value is exceeded or undercut, another relay

switches. The Open or Close relay actions are possible in each case

(see page 6-6).

Note

If the simple monitoring function (Open, Close) with one or two relays is not sufficient, use proportional output (see section 6.3.3).

A switching delay (t) can be set up for each relay for switching processes. This is the time period for which a limiting value must be exceeded before the relay switches. This prevents frequent switching if the measured values are close to the limiting value.

System 182 Relay outputs

6.3.3 Proportional output

In the case of proportional output, a relay switches cyclically on and off in a defined measured value range (proportional range). At the same time, the relay switches with a:

 duration of operation that corresponds to the measured value

(pulse-width output, see page 6-9) or

 switching frequency (frequency output, see page 6-10).

Proportional outputs can be used in the following way:

 Output with one relay:

An output range is defined with a Start value and an End value. No

output takes place above and below the output range

(see page 6-8).

 Output with two relays:

An output range is defined for each relay with a Start value and an

End value. One relay outputs in the upper output range and a further

relay in the lower output range (see page 6-8).

Pulse width output The output via the pulse width is used, e.g. for controlling valves.

Pulse-width regulation changes the duration of operation (ton) of the output signal. Depending on the position of the measured value in the proportional range, the relay is operated for a longer or shorter period.

= turn-on duration

 If the measured value is at the end of the proportional range (End

value), the turn-on duration (t

) is long, the turn-off duration is short.

This means the relay operates for a longer period.

 If the measured value is at the beginning of the proportional range

(Start value), the turn-on duration (t

) is short, and the relay

operates for a correspondingly shorter period.

Note

If the duration of the closing or opening pulse is shorter than 0.1 s, the relay remains open or closed for the complete cycle duration.

Frequency output Switching frequency output is used, e.g. for controlling dosing pumps.

In contrast to the pulse-width output, not the pulse width is modulated with frequency output but the switching frequency of the output signal. Depending on the position of the measured value in the proportional range, the relay is switched more often or less often.

Fig. 6-5 Relay output of frequency output

While the selected switching duration (ton = 0.3 s) always remains constant, the switching frequency at which the relay switches changes depending on the measured value.

 If the measured value is at the end of the proportional range (End

value), the switching frequency is higher.

 If the measured value is at the beginning of the proportional range

(Start value), the switching frequency is low.

In the case of a Collective error message, the relay opens if one of the following malfunctions occurs:

 One of the sensors properly registered at the controller does not

supply a valid main measured value

ba76024e01 02/2012

 One of the sensors properly registered at the controller does not

supply a valid secondary measured value

In any case, the relay remains open for 10 seconds and only closes when the malfunction is no longer present.

In the following cases, the relay does not

open despite an invalid

measured value:

 The sensor is being calibrated

 The sensor is in the maintenance condition

 The sensor is being cleaned with the aid of a valve module in the

system (compressed air operated cleaning system).

General

sensor errors

Sensor messages include errors and information that are registered by the sensor.

The special sensor errors are sensor-dependent. Details of this are given in the component operating manual of the respective sensor.

Init can prompt a relay action for a short time, depending

on the starting behavior of the system
