    Note. Non-Atex (Ex) Sensors variants of the models listed in the manual may also be used with the SIL O2 Analyser as long as they are installed in a Non-ATEX (Ex) or ‚Safe‘ area or zone.

  • Page 7: Installation And Operation

    Sensor options are detailed in the Specification section of this manual. If the SIL O2 Analyser has been supplied with a Sensor, the two units will have been calibrated at the Ntron factory prior to delivery. Otherwise, if a Sensor is supplied separately from the SIL O2 Analyser, a calibration will be required prior to putting the system into operational service.

  • Page 9 The SIL O2 oxygen analyzer is an associated explosion-proof [Ex ia] IIC or [Ex ib] IIC electrical device and should always be used outside potentially explosive areas (in a safe area). Only electrical circuits, certified as intrinsically safe, can be connected to other intrinsically safe circuits in the Ex zone.

  • Page 10: Installation

    Specification section of this manual. The SIL O2 analyzer is designed for DIN rail mounting and can be supplied mounted in an additional enclosure or provided without an additional enclosure for customer mounting in a system enclosure or control panel.

  • Page 11: Electrical And Interface Connections

    2.3.1 Sensor Input and Customer Interface Wiring The Ntron ATEX Sensor selected for use with the SIL O2 Analyser as listed in the Installation section previously, has intrinisically safe parameter values which match the Isolation Barrier output which is built into the SIL O2 Analyser.

  • Page 12: Operational Settings And Wiring Configuration

    SIL O2 Analyser and Sensor unit will detail these settings. See the Ntron SIL O2 Technical and Safety manual for further details. The SIL O2 Analyser has a main trip Relay referred to as RL3. This is not programmable and is normally open(contacts)/de-energised when the Analyser is not under power. The Relay energises and its associate contacts close when power is applied and the Analyser and Sensor are healthy and ready to operate.

  • Page 13: Typical Relay Configuration

    This range can not be adjusted. If the 4-20 mA output is not used, the SIL O2 terminals T11 and T12 must be wired by the user. This output is internally connected in series with the SIL O2 Analyzer digital display, which will not work if the...

    20.9% O2. It is possible to also adjust the Zero point of the SIL O2 Analyser. Typically this would only be required when fitting a new/replacement Sensor. A Complete calibration procedure is given below.

  • Page 17: Setting The Zero Point

    The sensors to be used with the SIL O2 unit will generally give a small output at zero oxygen levels. The zero adjustment function allows the user to adjust this small signal so that the SIL 2 analyzer displays 0.0 when no...

  • Page 18: Span Calibration

    2.4.3 SPAN Calibration This can be done periodically or as needed in accordance with the requirements of the calibration protocol. Calibration can be performed by applying either clean ambient air or a 20.9% certified oxygen rate to the sensor. Note: •...

  • Page 19: Operational Safety And Maintenance Instructions

    3.1 Fault conditions The SIL O2 Analyzer failure operation is not locked out by a fault. When a fault condition is repaired, the trip relay RL3 and the red fault indicator will return to their "healthy" or "operational" state after a few seconds following an automatic internal cyclic check.

  • Page 20: Troubleshooting

    3.4 Troubleshooting Possible Faults and their solutions The following possible conditions are applicable to a system (Sil Analyser and Sensor) already installed and commissioned. Some conditions below may also be applied to new systems not yet commissioned. • Action: Performing a Zero calibration when the Oxygen Sensor is in ambient air. Problem: An incorrect Zero level input to the Analyser will result in an overrange fault.

  • Page 21: Possible Sensor Faults

    Solution: Sensor is at end of life. Sensor has been wetted or contaminated. The Sensor output signal can be checked at the SIL O2 Analyser terminals 14 and 16. See specification section for details of a healthy output signal. Problem:.

  • Page 22: General Maintenance

    The SIL O2 Analyser requires little physical maintenance. The user Enclosure into which it is housed should provide protection against a build up of dust or other contaminants on the surface of the SIL O2 Analyser housing. If such contaminants are seen during regular inspection, such can be removed by gentle suction device or by wiping with a damp but not wet, cloth.
