The Pharma II Compact Control Monitor forsanitary diaphragm valve monitoring andcontrol incorporates new design features thatmeet the challenges of modernpharmaceutical and biotech facilityapplications. Its low profile and tool-freeaccess make it ideal for short bend radiusinstallations. The Pharma II utilizes a patentpending, self-setting limit switch assembly,engineered to reduce nuisance alarms andfalse trips created by changes in valve seatdurometer. The switch assembly containshermetically sealed bifurcated switches whosesnap-action and self-cleaning functionalitiesmake them ideal for use with high or lowcurrent switching of inductive and resistiveloads. Zero leakage current means excellentperformance in modern, low current I/Osystems. The patent-pending, self-setting HighDefinition Visual Indicator provides a 360° viewup to 100 feet away, and the modular designallows the easy addition of our puck-stylesolenoid valve base. The Pharma II solenoidpilot valve employs lapped-spool technologyfor proven reliability and minimal maintenance.Features• Compact 3.39" height (without solenoid)• Modular– Base plate mounted Puck solenoid withQuickSwap twist lock installation– QuickSwap conventional and networkelectronic modules• Designed for simple installation andmaintenance– No tool enclosure entry– Screw on lid– Easy access to terminal strip for internalwiring– Modular design allows the quick changeout of electronics/switch module orsolenoid.• Compatible with all valve stroke sizes andall manufacturers products

Features and Benefits• 4 DPDT or 6 SPDT switch option and upto a 24 point terminal strip available.• The Eliminator option provides an easyintegrated connection to an externalsolenoid valve.• CS Transmitter Option – Combine localvisual display with 4-20 mA positionfeedback. The analog current transmitterfeatures the latest technology in solidstate design with one of the lowestoperating voltages (6.5 VDC) in theindustry.• The Westlock Beacon is manufacturedfrom a high impact strength and corrosionresistant co-polyester that offers 360degree instant visual recognition of valveposition from up to 150 feet away.• Touch set cams are hand adjustable,spring loaded and self-locking providingquick calibration of position sensors.• Terminal strips are pre-wired andnumbered with generous working spacefor ease of use.• All units are standard with an additionalconduit for easy field wiring and mountingaccessories.• All AccuTrak™ and Quantum productsutilize a standardized mounting patternfor easy adaptation to common bracketry.• Low copper content aluminum enclosures(0.2% maximum copper content) ensurerobust performance in corrosiveenvironments.• Captive screws on cover prevent lostscrews during installation andmaintenance.

EX switches feature the smallest UL-listedhousings available for use in hazardous locations.Flame paths within the housingcool exploding gases below the kindlingtemperature before they reach the explosivegases surrounding the housing.The enclosed switching unit, which is held inplace by screws, is accessible when thecover plate is removed. A tapped conduitopening is located in one end of one groupof EX listings; while a second group has a conduitopening in each end of the switch.These switches are not sealed against liquidsand are not intended to be subjected toliquid splash or for outdoor applications. If asealed explosion-proof switch is required,refer to the type CX and LSX.
