14 System Maintenance
14.1 Overview
It is recommended that the StarPac 3 system calibration be checked every six months. If, after checking the unit, a
component is determined to be defective, the following section will help with the component replacement.
The following items may be needed to install, start up and calibrate the unit‘s electronics.
• Power supply: 24 VDC, 150 mA
• Digital volt meter with 4 - 20 mA range
• Air supply: 50 psig minimum, 80-100 psig preferred
• Gauges or the ability to accurately determine process pressures and valve air supply pressures
• 4 - 20 mA command source
• Thermocouple calibrator or simulator with 0 to 500° Celsius range
14.2 Mechanical Subsystem Maintenance
Refer to the appropriate Flowserve Installation, Operation & Maintenance (IOM) instructions for details on repair and
maintenance of the control valve actuator components. Please refer to the manufacturers’ manuals for maintenance
and operation instructions for non-pneumatic actuators, e.g., electric or electro-hydraulic actuators.
WARNING
: The process line must be depressurized and drained of process fluid and decontaminated prior to
working on internal valve components. Failure to do so may cause serious injury to personnel.
1.
Depressurize the line, decontaminate the valve (if needed) and shut off the air supply to the valve positioner.
2.
Disconnect the actuator air tubes from the unit.
3.
Disconnect the two mounting bolts that attach the StarPac 3 system bracket.
4.
Disconnect the follower arm from the unit base. This is done by removing the follower arm nut and washer
and pulling the arm off the shaft. Notice that the shaft is slightly spring loaded.
5.
The actuator subassembly is now isolated and is removed by loosening the bonnet bolts and lifting the actu-
ator away from the body.
6.
The tubing holds the StarPac 3 base in place, eliminating the need to disconnect wiring or air connections.
STOP!
