This manual is produced to enable a
competent user to install, operate,
adjust and inspect Rotork IQT
range valve actuators. Only persons
competent by virtue of their training
or experience should install, maintain
and repair Rotork actuators. Work
undertaken must be carried out in
accordance with the instructions in
this and any other relevant manuals.
The user and those persons working
on this equipment should be familiar
with their responsibilities under any
statutory provisions relating to the
Health and Safety of their workplace.
Due consideration of additional
hazards should be taken when using
the IQT range of actuators with other
equipment. Should further information
and guidance relating to the safe use
of the Rotork IQT range of actuators be
required, it will be provided on request.
The electrical installation, maintenance
and use of these actuators should be
carried out in accordance with the
National Legislation and Statutory
Provisions relating to the safe use of
this equipment, applicable to the site of
installation.
For the UK: Electricity at Work
`Regulations 1989 and the guidance
given in the applicable edition of the
“IEE Wiring Regulations’’ should be
applied. Also the user should be fully
aware of his duties under the Health
and Safety Act 1974.
For the USA: NFPA70, National Electrical
Code
®
is applicable.
The mechanical installation should be
carried out as outlined in this manual
and also in accordance with relevant
standards such as British Standard
Codes of Practice. If the actuator has
nameplates indicating that it is suitable
for installation in hazardous areas then
the actuator may be installed in Zone
1, Zone 21, Zone 2 and Zone 22 (or Div
1 or Div 2, class I or Class II) classified
hazardous area locations only. It should
not be installed in hazardous area
locations with an ignition temperature
less than 135°C, unless suitability for
lower ignition temperatures has been
indicated on the actuator nameplate.
It should only be installed in hazardous
area locations compatible with the gas
groups stated on the nameplate.
The electrical installation, maintenance
and the use of the actuator should be
carried out in accordance with the code
of practice relevant for that particular
Hazardous Area certification.
No inspection or repair should be
undertaken unless it conforms to the
specific hazardous area certification
requirements. Under no circumstances
should any modification or alteration be
carried out on the actuator as this could
invalidate the actuators hazardous
area approval certification. Access to
live electrical conductors is forbidden
in the hazardous area unless this is
done under a special permit to work,
otherwise all power should be isolated
and the actuator moved to a non-
hazardous area for repair or attention.
WARNING: Thermostat Bypass
If the actuator is configured to bypass
the motor thermostat then the hazardous
area certification will be invalidated.
Additional electrical hazards may occur
when using this configuration.
The
user should ensure that any necessary
additional safety measures are considered.
WARNING: Enclosure Materials
IQT actuators are manufactured from
aluminium alloy with stainless steel.
The user must ensure that the operating
environment and any materials
surrounding the actuator cannot lead
to a reduction in the safe use of, or the
protection afforded by, the actuator.
Where appropriate the user must
ensure the actuator is suitably protected
against its operating environment.
WARNING: Operating by Han
d
With respect to handwheel operation of
Rotork electric actuators, see warning
on p3.
This actuator must only be
located in areas where the risk of
impact to the viewing window
is low.
Actuator may start and
operate when remote control is
selected, depending on remote
control signal status and actuator
configuration.
