PT-500 • Rev.C2, 1/09 Instructions All units are factory calibrated prior to shipment. 1. Output The PT-500 transmitter is a two wire 4-20mA output devce. The two wire system connects the power supply, transmitter, and indicating/recording instruments in a series circuit. This creates a “current loop” with the transmitter functioning as a current regulating device. 2. Wiring Information Below, are the wiring diagrams, and terminal coding notes, needed to assist you in wiring your transducer.

PT-500 • Rev.C2, 1/09 Field Maintenance 1. Zero Adjust The zero output (4mA) can be adjusted by holding a magnet close to the can, approx. 1 1/2 inches from the top or bottom of the can. If the zero output values do not change right away, hold the magnet in place near the top of the can until the values change, up to two minutes. If there is no change, repeat the procedure near the bottom of the can. If there is still no change,consult the factory.
Rev. C2, 1/09 PT-500 3. Desiccant Drying Cartridge The desiccant drying cartridge with vent tube adapter is used to keep vapor from condensing in the vent tube. Condensation in the vent tube could create an output offset. The installation of the desiccant drying cartridge is quick and easy. Common installation methods are cable tie, velcro and cable clamps Note: Replacement of the desiccant cartridge is recommended when the desiccant crystals have turned from blue to pink.
