Mounting the SVI II AP
This guide provides installation instructions for mounting an
SVI II AP on both rotary and reciprocating actuated valves. The
mounting process can be broken down into the following:
Attach the mounting bracket to the actuator.
Install the magnetic assembly.
Assemble the SVI II AP on the mounting bracket.
NOTE
The SVI II AP should be mounted with the conduit
connections down in order to facilitate drainage of
condensate from the conduit.
Necessary Precautions
To avoid injury or the process being affected when installing or
replacing a positioner on a control valve, ensure that:
If the valve is located in a hazardous area make sure the
area has been certified as
safe
or that all electrical
power to the area has been disconnected before
removing any covers or disconnecting any leads.
Shut off air supply to the actuator and to any valve
mounted equipment.
Ensure the valve is isolated from the process by either
shutting off the process or using bypass valves for
isolation. Tag shutoff or bypass valves to guard against
a
turn-on
while work is in progress.
Bleed air from actuator and check that valve is in its
unenergized position.
It is now safe to disconnect and remove any valve mounted
equipment that is being replaced.
