SP7-10 Digital positioner
Safe operation of these products can only be guaranteed if they are properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.13) 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.
WARNING: The maximum process fluid temperature must be suitable for use
if the unit is to be used in any potential explosive atmosphere. For the device
maintenance in a potentially explosive atmosphere, we recommend the usage
of tools which do not produce and / or propagate sparks.
1.1 Wiring
Every effort has been made during the design of the positioner to ensure the safety of the
user, but the following precautions must be followed:
i) Ensure correct installation. Safety may be compromised if the installation of the product
is not carried out as specified in this manual.
ii) Wiring should be carried out in accordance with IEC 60364 or equivalent.
iii) Fuses should not be installed in the protective earth conductor. The integrity of the
installation protective earth system must not be compromised by the disconnection or
removal of other equipment.
1.2 Intended use
Referring to the Installation and Maintenance Instructions, product markings and Technical
Information Sheet, check that the product is suitable for the intended use / application.
1.3 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.
1.4 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
1.5 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.
1.6 Hazardous environment around the product
Consider: lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of temperature, hot
surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery.

IM-P706-02-US Issue 1 5
SP7-10 Digital positioner
1.7 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 opened and closed progressively to avoid
system shocks.
1.8 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 labelling of closed valves. Do
not assume that the system has depressurised even when the pressure gauge indicates zero.
1.9 Temperature
Allow time for temperature to normalise after isolation to avoid the danger of burns.
1.10 Tools and consumables
Before starting work ensure that you have suitable tools and / or consumables available. Use
only genuine Spirax Sarco replacement parts.
1.11 Protective clothing
Consider whether you and / or others in the vicinity require any protective clothing to protect
against the hazards of, for example, chemicals, high / low temperature, radiation, noise,
falling objects, and dangers to eyes and face.
1.12 Permits to work
All work must be carried out or be supervised by a suitably competent person.Installation
and operating personnel should be trained in the correct use of the product according to
the Installation and Maintenance Instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where there is no
such system, it is recommended that a responsible person should know what work is going
on and, where necessary, arrange to have an assistant whose primary responsibility is safety.
Post 'warning notices' if necessary.
1.13 Handling
Manual handling of large and / or heavy products may present a risk of injury. Lifting, pushing,
pulling, carrying or supporting a load by bodily force can cause injury particularly to the
back. You are advised to assess the risks taking into account the task, the individual, the
load and the working environment and use the appropriate handling method depending on
the circumstances of the work being done.
1.14 Residual hazards
In normal use the external surface of the product may be hot. Many products are not self-
draining. Take due care when dismantling or removing the product from an installation (refer
to 'Maintenance instructions').

1.15 Freezing
Provision must be made to protect products which are not self-draining against frost damage
in environments where they may be exposed to temperatures below freezing point.
1.16 Returning products
Customers and stockists are reminded that under EC Health, Safety and Environment Law,
when returning products to Spirax Sarco they must provide information on any hazards and
the precautions to be taken due to contamination residues or mechanical damage which may
present a health, safety or environmental risk. This information must be provided in writing
including Health and Safety data sheets relating to any substances identified as hazardous
or potentially hazardous.
Product return procedure
Please provide the following information with any equipment being returned:
1. Your name, Company name, address and telephone number, order number and invoice and
return delivery address.
2. Description of equipment being returned.
3. Description of the fault.
4. If the equipment is being returned under warranty, please indicate:
i. Date of purchase
ii. Original order number
iii. Serial number
Please return all items to your local Spirax Sarco branch.
Please ensure all items are suitably packed for transit (preferably in the original cartons).

SP7-10 Digital positioner
2.1 Introduction
The SP7-1 is an intelligent digital positioner available with communication via HART.®within the
positioner product range. Unsurpassed shock absorption and vibration compensation from 10 g to
80 Hz distinguishes the SP7-1 from other products and guarantees reliable operation in nearly any
area under the harshest ambient conditions.
2.2 Operating principle
1LCI plug
2Setpoint signal 4 to 20 mA
3Binary input
4Binary output
5Supply air: 1.4 to 6 bar
(20 to 90 psi, 0.14 to 0.6 MPa)
6Exhaust
2. General product information
The SP7-1 is an electronically configurable positioner with communication capabilities designed for
mounting on pneumatic linear or rotary actuators.
Fully automatic determination of the control parameters and adaptation to the positioner allow for
considerable time savings as well as optimum control behavior.

3.1.2 Measuring and operating ranges of the positioner
Arrow (1) on the device feedback
shaft (position feedback) point must
move between the arrow marks (2)
Operating range for linear actuators:
The operating range for linear
actuators is ±45° symmetrically
to the longitudinal axis.
The usable span within the
operating range is at least
25° (recommended figure
40°). The usable span
does not necessarily need
to run symmetrically to the
longitudinal axis.
Operating range of rotary
actuators:
The usable span is 90°,
which must be entirely within
the measuring range, but
does not necessarily need
to run symmetrically to the
longitudinal axis.
Note
During installation make sure
that the actuator travel or
rotation angle for position
feedback is implemented
correctly.
