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.

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.

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.

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.
