SX80 and SX90 Quickstart Guide

Safe operation of this product can only be guaranteed if it is properly

installed, commissioned, used and maintained by qualified

personnel (see Section 1.11) in compliance with the operating

instructions. General installation and safety instructions for pipeline

and plant construction, as well as the proper use of tools and safety

equipment must also be complied with.

Safety and EMC protection can seriously be impaired if the unit is

not used in the manner specified. It is the responsibility of the

installer to ensure the safety and EMC of the installation.

Safety

This instrument complies with the European Low Voltage Directive

73/23/EEC, by the application of the safety standard EN 61010.

Unpacking and storage

If on receipt, the packing or unit is damaged do not install but

contact your supplier. If the unit is being stored before use, protect

it from humidity and dust within an ambient temperature range of

-30ºC to +75ºC.

Electrostatic discharge precautions

Always observe all electrostatic precautions before handling the

unit.

Service and repair

This instrument has no user serviceable parts. Contact your supplier

for repair.

1. Safety information

IM-P323-32

CTLS Issue 5 5

SX80 and SX90 Quickstart Guide

Cleaning

Isopropyl alcohol may be used to clean labels. Do not use water or

water based products. A mild soap solution may be used to clean

other exterior surfaces.

Electromagnetic compatibility

This instrument conforms with the essential protection requirements

of the EMC Directive 89/336/EEC, by the application of a Technical

Construction File. It satisfies the general requirements of the

industrial environment defined in EN 61326.

Caution - Charged capacitors

Before removing an instrument from its sleeve, disconnect the

supply and wait at least two minutes to allow capacitors to

discharge. Avoid touching the exposed electronics of an instrument

when withdrawing it from the sleeve.

Safety symbols used on the instrument have the following meaning:

Caution, refer to

throughout

accompanying

documents.

Equipment

protected by

double insulation.

Installation category and pollution degree

This unit has been designed to conform to BS EN 61010 installation

Category II and Pollution Degree 2, defined as follows: Installation

Category II (CAT II) – The rated impulse voltage for equipment on

nominal 230 V supply is 2500 V.

Pollution Degree 2 – Normally only non-conductive pollution occurs.

However, a temporary conductivity caused by condensation must

be expected.

IM-P323-32

CTLS Issue 5

SX80 and SX90 Quickstart Guide

Personnel

Installation must be carried out by suitably qualified personnel.

Enclosure of live parts

To prevent hands or metal tools touching parts that may be

electrically live, the controller must be installed in an enclosure.

Caution - Live sensors

The controller is designed to operate if the temperature sensor is

connected directly to an electrical heating element. However, you

must ensure that service personnel do not touch connections to

these inputs while they are live. With a sensor, all cables, connectors

and switches for connecting the sensor must be mains rated for use

in 240 Vac CAT II.

Wiring

It is important to connect the unit in accordance with the data within

this document ensuring that the protective earth connection is

ALWAYS fitted first and disconnected last. Wiring must comply with

all local wiring regulations, i.e. UK, the latest IEE wiring regulations,

(BS 7671), and USA, NEC Class 1 wiring methods.

Do not connect the ac supply to the low voltage

sensor input or low level inputs and outputs.

IM-P323-32

CTLS Issue 5 7

SX80 and SX90 Quickstart Guide

Voltage rating

The maximum continuous voltage applied between any of the

following terminals must not exceed 240 Vac:

- Relay output to logic, dc or sensor connections.

- Any connection to ground.

Warning: The controller must not be wired to a three phase supply

with an unearthed star connection. Under fault conditions such a

supply could rise above 240 Vac with respect to ground and the

product would not be safe.

Conductive pollution

Electrically conductive pollution i.e. carbon dust, MUST be excluded

from the enclosure in which the controller is installed. To secure a

suitable atmosphere in conditions of conductive pollution, fit an air

filter to the air intake of the enclosure. Where condensation is likely,

include a thermostatically controlled heater in the enclosure.

Grounding of the temperature sensor shield

In some installations it is common practice to replace the

temperature sensor while the controller is still powered up. Under

these conditions, as additional protection against electric shock,

we recommend that the shield of the temperature sensor is ground.

Do not rely on grounding through the framework of the machine.

Overtemperature protection

To prevent overheating of the process under fault conditions, a

separate overtemperature protection unit should be fitted which

will isolate the heating circuit. This must have an independent

temperature sensor.

Note: Alarm relays within the unit will not give protection under all

failure conditions.

SX80 and SX90 Quickstart Guide

Installation requirements for EMC

To comply with European EMC directive certain installation

precautions are necessary:

Relay outputs – It may be necessary to fit a suitable filter to suppress

conducted emissions.

Filter requirements depend on the type of load. Typical applications

may use

Schaffner FN321 or FN612.

1.1 Intended use

i) Check that the product is suitable for its intended application.

ii) Check material suitability, pressure and temperature and their

maximum and minimum values. If the maximum operating limits

of the product are lower than those of the system in which it is

being fitted, or if malfunction of the product could result in a

dangerous overpressure or overtemperature occurrence, ensure

a safety device is included in the system to prevent such over-

limit situations.

iii) Determine the correct installation situation and direction of

fluid flow.

iv) Spirax Sarco products are not intended to withstand external

stresses that may be induced by any system to which they are

fitted. It is the responsibility of the installer to consider these

stresses and take adequate precautions to minimize them.

v) Remove protection covers from all connections and protective

film from all name-plates, where appropriate, before installation

on steam or other high temperature applications.

1.2 Access

Ensure safe access and if necessary a safe working platform

(suitably guarded) before attempting to work on the product.

Arrange suitable lifting gear if required.

1.3 Lighting

Ensure adequate lighting, particularly where detailed or intricate

work is required.

1.4 Hazardous liquids or gases in the

pipeline

Consider what is in the pipeline or what may have been in the

pipeline at some previous time. Consider: flammable materials,

substances hazardous to health, extremes of temperature.

1.5 Hazardous environment around the

product

Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits),

dangerous gases, extremes of temperature, hot surfaces, fire hazard

(e.g. during welding), excessive noise, moving machinery.

1.6 The system

Consider the effect on the complete system of the work proposed.

Will any proposed action (e.g. closing isolation valves, electrical

isolation) put any other part of the system or any personnel at risk?

Dangers might include isolation of vents or protective devices or

the rendering ineffective of controls or alarms. Ensure isolation

valves are turned on and off in a gradual way to avoid system shocks.

1.7 Pressure systems

Ensure that any pressure is isolated and safely vented to

atmospheric pressure. Consider double isolation (double block and

bleed) and the locking or labeling of closed valves. Do not assume

that the system has depressurized even when the pressure gauge

indicates zero.

1.8 Temperature

Allow time for temperature to normalize after isolation to avoid the

danger of burns.

If the instrument is to be stored before use, protect from humidity

and dust in an ambient temperature of –30 °C to +75 °C.
