6. Installation and Maintenance Recommendations
- Installation Position: It should be installed in the designated slot of the 3500/61 mainframe to ensure close combination with the rack to avoid the impact of vibration.
- Electrical Wiring: Follow the wiring diagram on the backplane of the module to connect the sensor and power cord, and pay attention to distinguishing the wiring polarity of RTD and thermocouple.
- Regular Calibration: It is recommended to calibrate the sensor once a year or every two years to maintain the high precision of ±0.1%.
- Troubleshooting: The diagnostic alarm of the monitoring system (such as light flashing) can usually indicate module failure or sensor open/short circuit, which needs to be checked in time.
