For 45APE Series – Low setpoint should be limited to the lower 1/2 scale and upper setpoint should be limited to the upper 1 /2 scale.

If the liquid in the system freezes, it will expand and will damage the tube.

Use shock mounts as necessary to prevent excessive vibration.

Do not twist case when installing, this will damage internal components and will void the warranty.

Use the wrench on the shank to tighten or loosen the connection.For direct mounting into the process, a vertical or ninety-degree mounting is recommended.Dope or use teflon tape on connection threads.The instrument is enclosed in an explosion-proof case and CSA rated for Class I, Division 1, Groups C and D.Ĩ Artículos Relacionados Precauciones de instalación: PT167EX is a pressure switch gauge instrument connected to a threaded pressure diaphragm housing. These units do not include low contact lockout. 45APE and 45APEF are versions of the OPLC Series featuring 2 snap-acting SPDT switches instead of the pointer-type contacts. OS and -ES options include oil sealed and environment sealed case for corrosive environments, feature a panel mount case or screw directly into the process. OPLBP is a version of the OPLC featuring pilot duty limit switches connected to an internal latching control relay for on/off control directly or through a motor starter. OPLFG gage indication-only pressure instrument is similar to OPLFC models, without switch (limit) contacts. A method to override the low-limit contact for a start-up is provided on OPLC models. OPLC and OPLFC gage instruments have high and low limit contacts to monitor, alarm or shut down.
