EXTERNAL WIRING 1. When connecting panel meters, please refer to the wiring diagram attached and the related operation manual. 2. Wiring connection should be kept away from high voltage cables, (e.g. power cables) to prevent electrical interference. Shield wire 3. Operating voltage should be kept higher than 13Vdc. 4. Wiring should be used in shielded insulated cable. Breather capillary 5. Provide additional power supply if required (Diagram 8). If installing 2 panel meters at different location, please refer to diagram 9. Panel meter Extra DC Power Supply Pressure Sensor Digital panel...

INSTALLATION 1. Note the installation diagrams to the right and select your model accordingly. EC1100 EC1300 2. The flange type transducer is equipped with a side mounted electrical housing. 3. The models EC1100 to EC1310 series have 3 multi-thread copper wires and a breather capillary. Avoid bending cables to ensure maximum accuracy. 4. 4. Do not use liquid that can crystallize or solidify in the pressure transducers and sensors. 5. The tank or vessel should not be vacuum or no pressure state. 8. Handle the sensor probes with care. The sensor probe is delicate and vibration or shock can...

1 Since Zero & Span adjustment have been made in the factory. Don't change the setting unless necessary. Zero represents the 4mA for an empty tank and Span represents the 20mA for a full tank. 1 Adjustment range: (SPAN) 18~24mA, (ZERO) 3~5mA. 1 In the case where sensor output requires more than the 4~20mA signal, a panel meter with programmable input (0~25.5mA) can be used. ZERO The electrical housing for transducer with flange. ZERO The electrical housing for pressure transducer. Pressure Unit Conversion Constants PSI
