PT 6. INSTALLATION Recommendation 1. Please confirm the configuration for Pressure Transmitter i.e. 2- wire, 3-wire and accordingly follow the wiring procedure. Ensure that the excitation voltage is supplied to the correct points and is with in the specified limits for that particular configuration as mentioned in the table above. 2. When installed, ensure that the transmitter is not subjected to the excessive sources, and it should be considered before installing the Transmitter.
PT 7.2 Example for Usage 8. MAINTENANCE Troubleshooting S. No. SPECIFICATIONS ELIMINATE 1 No output • • Check the wiring configuration. Check the input power supply. 2 No variation in output • • Check for leakage at pressure port / point. Check the span set of Indicating Instrument. 3 Pressure not holding at constant input pressure. • • Check for leakage pressure point. Check for the connections ensure they are properly tightened.

PT 9. SAFETY PRECAUTIONS 1. The unit should be powered for 15 minutes before use. 2. Use in ambient temperature of 0-60˚C. 3. Avoid vibrations, shock, excessive dust, corrosive chemical materials or gaseous environment. 4. Input wire should not be too long. If measured signal have to be far away from the unit, please use 2core shielded cable. 5. Use this instrument in the scope of its specifications, otherwise fire or malfunctions may result. 6.
