2.4 Warnings
This information is needed to avoid a safety hazard,
which might cause bodily injury
This information is necessary to prevent damage to
the product or other equipment
WARNING: Motor Thermostat / Motor Temperature
Under normal operation the surface temperature of the
actuator’s motor cover can exceed 60 °C above ambient.
Failure to correctly connect the thermostat may lead to
electrical hazards and invalidate the electrical safety case
and any safety approvals. Surface temperatures of motor
enclosures may reach temperatures which can cause
discomfort or injury to personnel accidentally coming
into contact with hot surfaces. Protection should be
provided by the user to protect against accidental contact
with hot surfaces. Failure to observe this precaution
could result in bodily injury.
WARNING: Surface Temperature
The installer/user must ensure that the actuator’s surface
temperature rating is not influenced by external heating/
cooling effect (e.g. valve/pipeline process temperatures).
CAUTION: Enclosure Materials
The CK Range of valve actuators are manufactured
from aluminum alloy with stainless steel fasteners.
The thrust bases are manufactured in SG iron. 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: Unexpected Start up
Actuator may start and operate at any time when power
is applied. This will be dependent on remote control
signal status and actuator configuration.
WARNING: Unit Weight
The actuator weight is shown on the nameplate.
Care must be taken to transport, move or lift the actuator
safely. Lifting information is available in section 6.
