Standard Installation
6 - Install the positioner with bracket onto the valve bonnet, using M8x16 screws. The
guide pin should pass through the middle of the guide arm. Do not fully tighten the
screws, to allow adjustment of the feedback lever. Move the bracket up and down
until the feedback lever is parallel to the guide arm.
7 - After adjusting the feedback lever, tighten the bracket screws firmly with a 13 mm
hex wrench.
8 - Make the pneumatic and electrical connections. See Sections 6 - Pneumatic
Connections and 7 - Electrical Connections.
9 - With all connections made, perform the auto-calibration process. See the
item 8.3 - Fast Calibration.
Risk of crushing and shearing with mounting kits that use a lever for position
detection. During commissioning and continuous operation, cuts or compression of
the limbs can occur in case of physical contact with the moving parts of the system.
The maximum pressure in the line after the regulator and before it enters the
positioner MUST NOT be greater than the actuator can support (to avoid damaging
it).
