DPI-C and DPI-E position indicators for BHH/BHHF actuators Data Sheet Sheet No.: DPI-C and DPI-E Date: October 2010 DPI-C and DPI-E The DPI-C and -E can be mounted in different mounting blocks or in LPU, with only internal wiring. Valve/actuator position is indicated by means of a precision potentiometer or 2 microswitches. Resistance (commonly used Ω output) increases during opening and decreases during closing the valve/ actuator. Set point adjustment is performed without tdismounting the DPI or cable from the LPU or block. Basic design: The DPI is designed to fit Bettis quarterturn valve actuators BHH and BHHF for use within the temperature range from -20° C to +80° C (-4° F to +176° F). The DPI range consists of the DPI-E (ON/OFF/switches), DPI-C (Continuous/potentiometer) and the hydraulic DPI-B (Bypass). For further information about the DPI-B, please see separate data sheet. Description: Mounting and adjustments: When mounting the DPI-C/-E be sure not to press the DPI too far towards the actuator. Several misadjustments of the DPI may cause destruction of the DPI. When the valve/actuator is closed you may adjust the DPI by screwing it towards the actuator until the... - DPI-C: potentiometer reaches the desired 300 Ω (1500 Ω), or - DPI-E: CLOSED switch closes (opens if NC configuration), and then adjust the desired overlap (1° - 5°). Check the indicator signal in open position. When DPI is mounted in a block, make sure that the locking screw is tightened sufficiently to prevent the DPI from turning. When mounted in LPU remember to tighten the counter-nut. If correct adjustment is not possible - check the yoke distance “X” (see enlargement), and the presence of the yoke.
