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.
