User manual DHI MOLSTIC-S SUPPLY ONLY PLATFORM 14 IN. AND 12 IN. PNS 401876 AND 401877 INSTALLATION SHEET

[. . . ] supply only molstic-S platforms, P/N 401876 and 401877, provide inlet gas pressure regulation to either the Device Under Test (DUT) or the downstream molstic-S mounting systems. They are used to control the pressure supplied to an upstream DUT, or to adjust the flow rate through the system while calibrating a downstream DUT. [. . . ] SWG - not shown) Pressure reducing regulator Flow metering/shut-off valve Outlet adaptor, 1/4 in. Connect the outlet of the supply only platform to either the DUT or the inlet of the molstic-S. The outlet pressure of the pressure reducing regulator is controlled by adjusting the position of the control knob. Counterclockwise rotation, coupled with venting of the downstream side of the regulator plumbing, lowers the outlet pressure. Make final adjustments of control pressure in the direction of increasing pressure in order to obtain the most accurate and stable set point. Align the regulator's male VCR fitting with the mating female swivel nut and thread the nut onto the fitting. Over-tightening will damage the sealing beads and possibly cause system leakage. Place the flat side of the 60 mm nut plate under the molstic-S platform. Thread the socket head cap screws through the regulator bracket and tighten securely into the nut plate. INSTALLATION OF THE PRESSURE REDUCING REGULATOR ONTO MOLSTIC-S PLATFORM The pressure reducing regulator can be removed from the supply only molstic-S platform and mounted onto the molstic-S platform. Use the following procedure to install the pressure reducing regulator onto the molstic-S platform: Disconnect the gas supply from the supply only platform and vent any residual pressure. Using a pair of properly sized open-end wrenches ® loosen the VCR swivel nut on the downstream side of the VCR double male union between the regulator and the flow control/shut-off valve. Using the proper size hex wrench, remove and retain the socket head cap screws, washers, and nut plate that mount the regulator and its bracket to the supply only molstic-S platform, along with the VCR double male union. Using a pair of properly sized wrenches remove the VCR x tube adaptor on the inlet end of the molstic-S, remove the VCR gasket and discard. or 102923 for 1/2 in. ) securely against the sealing surface inside the female VCR swivel nut of the molstic-S inlet fitting.
