DXN with Nuclear GO Switches Installation, Operation & Maintenance 502.969.8000 Switch Orientation All Valvetop products are factory set for 90° rotation normal acting on parallel orientation with switch 1 (full clockwise) for the process valve closed position When changing orientation the target magnets will have to be relocated for your application. Target magnets are infinitely adjustable, allowing the Valvetop unit to be rotated 90°, 180°, or 270°... - Page 7 Switch Calibration Procedure Never perform switch calibration procedure while area is know to be hazardous For intrinsically safe models, the unit must be wired in accordance with the control drawing S-K094 and S-K094A. For standard explosion-proof models, the calibration may be preformed using a Volt-Ohm meter by using the Ohm setting across COM and NO.
