of this equipment for your installation consult Rotork prior
to installation.
WARNING: ELECTRIC SHOCK HAZARD
Installation and servicing must be performed only by
qualified personnel.
WARNING:
ELECTROSTATIC DISCHARGE
This equipment houses static sensitive devices. To protect the
internal components never touch the printed circuit boards
without using electrostatic (ESD) control procedures.
WARNING:
ENCLOSURE MATERIALS
CVA actuator castings are manufactured from aluminium alloy
with stainless steel fasteners. 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 HAND
Where actuators are supplied with the optional hand-
wheel, note that under no circumstances should any
additional lever device such as a wheel key or wrench
be applied to the hand-wheel in order to develop more
force when closing or opening the valve as this may
cause damage to the valve and/or actuator. It may also
cause the valve to become stuck in the seated or back
seated position.
WARNING:
RESERVE POWER PACK
Where actuators are supplied with the reserve Power
Pack Assembly please note that the actuator output
shaft may move after removal of the power supply.
Move the Knob Selector to the ‘STOP’ position to
prevent any unwanted electrical movement. The CVA
actuator and in particular the power pack contain no
user serviceable components and the top cover assembly
must be removed by suitably qualified personnel only.
