General Description: ACO -eries pressure switches consist of an open frame or enclosure protected switch unit and a transducer unit. They can be ordered separately for customer stocking and/or field assembly or as a complete factory-assembled unit. witch -eries pressure switch units incorporate the unique ACO TRI-OINT alternating fulcrum balance plate to control the operation of one or more electrical snapaction swtiches. The electrical snap-action switch together with the adjusting mechanism is a fully-tested, self-contained subassembly. Transducer Transducer unit incorporates a diaphragm/piston type pressure sensor, and is also a fully-tested, self-contained subassembly. Operation When pressure is applied to the transducer it is converted into movement of the piston. This piston movement is then used to control the operation of the electrical snap-action switch in the switch unit.

Transducers Fuel Gas UL requires a pressure transducer with a secondary chamber. This chamber allows the gas to be vented to a safe location in the event of primary sensing element rupture. The double chamber with vent pressure transducers meet this requirement. Fuel Oil UL requirements for fuel oil applications waive the double chamber requirement, providing the sensing element is made of Type 316 or eries type 316 pressure transducers are designed to meet this requirement. General ervice ressure transducers for water, steam and air service may be of the single chamber design. Enclosures ACO TRI-OINT -eries switches are available in three standard enclosures. All of these enclosed units are made in accordance with NEMA and UL standards. General urpose Type 1. These enclosures are designed for indoor use to protect personnel from accidental contact with the equipment. -eries general purpose switch units consist of a copper-free* aluminum die-cast body with a formed copper-free* aluminum cover; two 3/4 conduit hubs with one plug are provided. Watertight Type 4. Watertight and dust-tight enclosures are intended for use indoors and outdoors to protect the enclosed equipment against splashing or falling water, windblown dust and water, hose directed water, and severe external condensation. -eries watertight switch units have a copper-free* aluminum die-cast body and a formed copper-free* aluminum cover with Buna N gaskets; two 3/4 conduit hubs with one plug are provided. Explosion-roof Types 7 and 9. Type 7 enclosures are intended for use in locations defined by the National Electrical Code as Class I. Type 9 enclosures are intended for Class II locations. Class I locations are those in which flammable gases are or may be present in the air in sufficient quantities to produce explosive or ignitable mixtures. Class I locations are classified by group letter, which defines particular atmospheres. Division 1 locations are areas where the hazardous concentration exists continuously, intermittently or periodically under normal operating conditions. Division 2 locations are those where the hazardous vapors are present only in case of accidental rupture or breakdown of equipment. ACO TRI-OINT explosion-proof enclosures with letter B, C or D in the fifth position are listed for Class I, Groups B, C, and D, Division 1. They are also suitable for the less stringent Division 2 environment. Class II locations are those which are hazardous because of the presence of combustible dust. All ACO TRI-OINT explosion-proof enclosures are listed for Groups E, F, and G locations. The switch body and cover are die-cast copper-free* aluminum with a Buna N gasket. Two 3/4 conduit hubs with one plug are provided. FM Requirements Fuel Gas and Fuel Oil FM requires that fuel gas and fuel oil pressure supervisory switches shall have a visible external means of determining switch position. No specific constructions are required for the pressure transducer. witch units with visual position indication (suffix V ) in conjunction with single chamber pressure transducers will meet these requirements. General ervice tandard switch units with an adjusting nut cover, when mated to single chamber transducers, meet FM requirements for general applications such as airflow interlocking switches.

37 Definitions and Fluid Compatibility Guide Definitions Accuracy The maximum deviation from the set point under specified operating condition (ambient temperature, barometric pressure, etc.). Adjustable Deadband Refers to the capability of a pressure or temperature switch to allow the deadband to be adjusted over a given range. Certain ACO TRI-OINT switches have an adjustable deadband which can be adjusted over the total operating range of the switch. Adjustable Operating Range The pressure or temperature range of the switch within which the set point may be adjusted. Differential ressure The difference between two pressures. A differential pressure switch senses two pressure sources and can be adjusted to actuate on a desired difference between them. Guage ressure The actual reading of a typical pressure guage and is the difference between the pressure within a vessel and the atmospheric pressure surrounding it. It is normally measured in pounds per square inch (psig). Manual Reset The switch is a semi-automatic device which operates automatically with a signal change in one direction but must be manually reset once the signal returns to its original position. roof ressure A pressure which a device can be subjected to for extended periods of time without changes in its operating characteristics. Rated Overrange Temperature A temperature which a device can be subjected to for extended periods of time without changes in its operating characteristics. Repeatability The closeness of agreement among a number of consecutive measurements of the output for the same value of input under the same operating conditions approaching from the same direction. Repeatability is normally specified as a percentage of the upper limit of the operating range. Example: Operating range psig with +1% repeatability; equals +1% of 100 psig or +1 psig. Reset oint After a pressure or temperature switch has reached its set point and operated the electrical switch, it must return to a point called the reset point before the electrical switch can return to its original position. et oint The pressure reading at which the electrical switch element changes contact position (it can be specified either increasing or decreasing). witch Unit ACO uses the term switch unit to describe the electromechanical portion of a pressure or temperature switch. This is used in conjunction with a transducer unit to form a complete pressure or temperature switch. Transducer Unit ACO uses the term transducer unit to describe that portion of a pressure or temperature switch to which a pressure or temperature is applied which converts the input signal to another form of energy to operate the switch unit. Two-tage (Dual) ACO uses the term two stage to describe a pressure or temperature switch which is equivalent to two pressure or temperature switches which are independently adjustable. This switch is equivalent to two fixed deadband switches. Deadbands The deadband is the difference between the set point and reset point readings. Deadbands are listed in the specification tables at nominal values. They are representative of the deadbands of the units at the middle of the range. The deadband values for the full range adjustable deadband switches and limited adjustable deadband switches indicate the values through which the deadband may be adjusted. Generally, as the set point is adjusted through the operating range, the deadband will vary. Normally, it will become narrower as the set point is towards the bottom of the range, and will become wider when the set point is towards the top of the range. The graph shown below indicates representative trends of this type of deadband variation. Deadbands 1.5 x Value Value Half Value Bottom Mid Top osition of et oint in Range Temperature switch deadbands are a result of the characteristics of the vapor pressure curve as well as other factors. Normally, this results in a deadband which is narrower in the top third of the range than in the bottom third of the range. The values published are nominal and representative of midrange set points. 36
