All rights reserved.Connecting the Tubing and Air SupplyThe last step in hardware installation for the SVI II AP is to connect the air supply to the positioner.This section describes the process for connecting the tubing and air supply to a single and doubleacting positioner.WARNING Isolate the valve from the process and disconnect air tubing fromthe positioner. Disconnect air fully to avoid injury or processdamage.1. Install the tubing to the air supply port S (arrow only for High Flow).2. For a: Single acting actuator: Pipe the outbound air from the output pressure port I (arrow only for High Flow) to the actuator. Double acting actuator: Pipe output pressure port one I for one side ofthe actuator and output pressure port twoII for the other side of theactuator.3. Air supply: Supply pressure for single acting SVI II and AP High Flow:20 -100 psi (1.4 - 6.9 bar) (138 - 690 kPa) Supply pressure for double acting SVI II AP:25 - 150 psi (1.73 - 10.4 bar) (172.4 - 1034 kPa) Minimum tubing diameter 1⁄4" (6 mm x 4 mm)NOTE The SVI II AP Digital Valve Positioner is designed to operate withclean, dry, oil-free, instrument grade air to ANSI-ISA-57.3 1975(R1981) or ISA-S7.3-1975 (R1981) or with clean, dry, oil-free sweetnatural gas supply ((H2S content not to exceed 20 ppm) (SVI II APmodels SVI II AP/SD through SVI II AP/AD).Table 5:Dew Point At least 18° F (-7° C) below minimum anticipated ambienttemperatureParticulate Matter Filtered to 5 micronsOil Content Less than 1 ppm w/wContaminants Free of all corrosive contaminantsAir Supply Requirements
