Honeywell L404T Q & A

What does l404f mean?

• L404F: • Controllers may be used with steam, air, or noncombustible gases, or fluids noncorrosive to the pressure sensing element. L404T: • High pressure limits, break a circuit on oil pressure rise above setpoint. L404V: • Low pressure limits, makes a circuit on oil pressure rise above setpoint. Contents

What is l404v low pressure limit?

• • L404V Low Pressure limit, makes a circuit on oil pressure rise above setpoint. • Adjustments are made by screws on top of case. • Mount using 1/4 inch -18 NPT internal pipe threads or surface mount through base of case. • Ground screw terminal.

What is the limit off on a Honeywell l4064b?

• It is set to the furnace warm air temperature at which this safety switch is to turn off the oil or gas (or other) burner or heat source. On the Honeywell L4064B the LIMIT OFF is set to a temperature between 100 °F and 250 °F. From the factory this setting out of the box is 200 °F.

What happens when pressure rises above the l404 setpoint?

• When the pressure at the control rises above the L404 setpoint, a circuit opens between the R-B terminals. During a pressure fall, R-B will close at the setpoint pressure minus the switch differential. For example, if a controller is set to differential B(see Fig.11) with a controller setpoint of A, R-B will open when the pressure rises to A.

Honeywell Global

Honeywell International Inc. is an American publicly traded, multinational conglomerate headquartered in Charlotte, North Carolina. It primarily operates in four areas of business: aerospace, building technologies, performance materials and technologies (PMT), and safety and productivity solutions (SPS).[3] Honeywell is a Fortune 100 company, ranked 92nd in 2019.[4] The company has a global workforce of approximately 110,000 workers, with approximately 44,000 employed in the United States.[5][6] The current chairman and chief executive officer (CEO) is Darius Adamczyk.[7]

The company's current name, Honeywell International Inc., is the product of a merger of Honeywell Inc. by acquisition to AlliedSignal during 1999. The company headquarters were consolidated with AlliedSignal's headquarters in Morristown, New Jersey; however, the combined company chose the name "Honeywell" because of the considerable brand recognition.[8] Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries.[9][10] In 2020, Honeywell rejoined the Dow Jones Industrial Average index[11] and the following year moved its stock listing from the New York Stock Exchange to the Nasdaq
