Operations Manual January 2017 FGD-MAN-0047 External equipment It is necessary that reliable monitoring and indicating devices or systems be connected to the detector. These devices must be designed to produce clear visual and audible danger signals when high signal levels occur. Mount The controller should be mounted near eye-level and be easily accessible for calibration and maintenance purposes.
Operations Manual FGD-MAN-0047 January 2017 Section 4: Wire Explosion-proof installations may require an additional seal where conduit enters a non-hazardous area. Ensure conformity with local wiring codes. Field installation When pouring a seal, use a fiber dam to ensure proper formation of the seal.
Operations Manual January 2017 FGD-MAN-0047 Board assembly Sensor and controller There are three different user-allowed removable boards: relay board (solid state or electromechanical), option board, and Modbus board. These boards are field replaceable. Simply loosen the locking standoffs, Power to the unit must be OFF before wiring. remove one board, insert the other board, and tighten screws.

Operations Manual FGD-MAN-0047 January 2017 Section 7: Calibrate Calibration procedure The calibration procedure requires about five minutes to complete. If gas is not applied at the appropriate time, a calibration failure may occur. Refer to Calibration failure for specific information. For accurate performance, the Millennium should be calibrated using 50% span of the specific gas of concern.
Always use 1.0 liter per minute for distances every two seconds; no fault indicated. (calibration tube lengths) between10 ft. and 100 ft. Contact Emerson if 2. Flow certified clean air at a rate of 0.5 liters per minute through a remote calibration distance is greater than 100 ft/30 m is required.
Operations Manual FGD-MAN-0047 January 2017 7.4.2 Calibration failure If the calibration procedure fails, the display shows Fail Cal, the Status LED alternates red/green flashes and the analog output changes back and forth from 3.0–3.3 mA. The unit remains in a failed state until a Manual reset.
