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. Read and follow all installation instructions.Follow all safety warnings of the machine manufacturer.Make sure the machine cannot operate during installation.Disconnect all electrical power to the machine.It is your responsibility to have a qualified person install the unit.īefore Beginning Installation of this Product: A visual inspection of this product for damage during shipping is recommended before mounting.

The OPLFC-A-300 has a weatherproof die cast aluminum case, a clear polycarbonate lens, a 1/4 NPT process connection, a grade A phosphor bronze bourdon tube (brass tip/silver brazed) and a brass socket. Contact lead termination is by pigtail wires. It is typically used in control panels for compressors and pumps. The lockout must be done externally through the control circuit or with the optional "SA" lockout. This panel mount model does not have the low limit contact lockout. Inside the OPLFC-A-300, pointer closure against either of the adjustable contacts completes the pilot-duty circuit. The limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity. The limit switch can be wired directly to electric pilot circuits to operate alarms and/or shutdown engines and electric motors. This instrument is a combination pressure indicating gage with an adjustable low and high limit switch. The OPLFC-A-300 is a panel mounting 4.5" (114 mm) Pressure Swichgage®, with a range of 0-300 psi (0-2.07 MPa).
