1. Introduction

The Ntron SIL O2 Analyser is a ATEX approved SIL 2 rated Oxygen measuring instrument. It contains three programmable alarm settings, industry standard Analogue Output(active source) and a non-programmable safety trip relay. The range of operation is 0 to 25% Oxygen. The Reasolution is to 0.01%. Together with one of the range of Ntron ATEX approved Oxygen Sensors, it forms a SIL2 rated measurement unit which can operate on its own or as part of a larger installation.

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.

The Alarm settings are typically factory set according to the end user’s requirements. Interface software and hardware is available for the user to perform such functions themselves. Contact Ntron for further details.

1.1 The purpose of this User and Operation Manual

This Manual is limited to providing the user with necessary details on installation, interface wiring, operation and maintenance of the SIL O2 Analyser and Oxygen Sensor, to ensure safe and reliable operation of this Analyser and Sensor unit.

Note: This manual does not cover the design or application of a safety Instrumented System (SIS) into which the SIL O2 Analyser unit may be incorporated. Further details of this can be obtained in the Ntron

2. Installation and Operation

Note: For system application information, consult the SIL O2 Analyzer Technical User Manual

2.1 Notes for a safe installation

Please do not short-circuit the + and -ve sensor cables while connecting to the SIL O2 Analyzer. This could damage the sensor.

This system can also be used in a non-Ex area application. In all applications, the SIL O2 Analyzer Din rail module is always located in the non-Ex area!

Assignment of the mounting rail housing terminals with intrinsically safe circuits and non-intrinsically safe circuits is indicated on the nameplate and is clearly indicated. In addition, the 4-pin terminals of intrinsically safe circuits follow the standard color protocol for intrinsically safe terminal connections and are coloured Blue. Connections for intrinsically safe external circuits are arranged in such a way that, in accordance with EN 60079-11, the exposed parts are at least 50 mm from the exposed connections and parts of the non-intrinsically safe circuits.

For safe operation, a protective ground/earth connection to terminal 13 or 15 should be made.

Assembly / disassembly, installation, operation and maintenance may only be performed by qualified personnel in accordance with regulatory requirements and the SIL O2 Oxygen Analysis Manual.

During installation, the technical data and the electrical values of the connected circuits must be respected.

Electrical supply. The SILO2 Analyser operates with an Extra low Voltage (ELV) supply. (See specification section in this manual)No special precautions are necessary but the ELV supply to the SIL O2, if generated from a Mains power source, that mains power source and associated wiring must be in accordance with IEC/EN standards and is the responsibilty of the user to provide and to ensure correct and safe installation of such.

When the SIL O2 analyzer is integrated into another system, also refer to the system manual for additional operational information.

The Ntron SILO2 Analyser is designed for use with a range of Ntron ATEX certified Oxygen Sensors to form a measurement system.These 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.

I s s u e 3 0 - 11- 2018

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.

Before operation, the intrinsic safety must be verified for the SIL O2 oxygen analyzer circuit connected to the circuit of other equipment, including the interconnecting cabling. The data contained in the EC test certificate and the regulations of EN 60079-14: 2011-10 must be observed. The Sensors are ATEX rated devices and have certain conditions of use assigned.

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.

For Acetal-bodies Sensors, the following instructions apply;

The Sensor should be installed in such a way that it is not subject to impact by other objects and should not be located close to additional heat sources. Note the ambient temperature range as it appears on the Sensor labelling.

Care must be taken when installing equipment with plastic enclosures or plastic parts of enclosures to ensure that the equipment is protected from any situations that could cause a build up of static charge. The equipment must not be installed into locations in which it could come into contact with, through normal or abnormal circumstances, fast moving dust laden air/gas or non-conductive fluids. The equipment must be cleaned only with a damp cloth.

2.3.2 Operational Settings and Wiring Configuration

The SIL O2 Analyser has two presettable alarm levels and associated Relays, referred to as RL1 and RL2. It also has a third presettable alarm level with an associate Transistor Digital Output (DO) The programmed setting of these outputs can vary depending on application. The Inspection and Calibration certificate supplied with each 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.

The Analogue output is an industry standard 4-20mA active source output. The connected circuit should be of maximum resistance 420 ohm.

To meet the SIL 2 operational requirements as an Analyser and Sensor unit, the main trip Relay is required to be connected in series with other elements within the Analyser as shown in the diagrams below. For any other configurations, See the Ntron SIL O2 Technical and Safety manual for further details.

*Special case for use of the 4-20 mA analogue output within a safety system

When using the 4-20 mA analogue output from the SILO2 Oxygen Analyser within the safety system, this signal would typically be required to be processed by a safety PLC which would then activate the Final Trip Element. See the Ntron SIL O2 Technical and Safety manual for further

details.

These relays are programmed to respond to the measured Oxygen level setpoints (Alarms), rising or falling in the range 0-25% Oxygen. These are pre-set to the customer’s requirements.

They operate in ‘Fail Safe’ mode which means that they are energized (under current), presenting a closed

contact to the customer/user when the SIL O2 module is under power and the status is healthy/good. When at a level setpoint (Alarm) or when the SIL O2 module is not-powered, the relays are de-energised (not

under current), presenting an open contact to the customer/user. This is also known as ‘Fail Open’ (FO)

condition.

Transisitor (DO)

This is an NPN device that can switch 24VDC and can be configured to be normally open or normally closed.

Analogue 4-20mA

This is an active output and requires connection to a passive external circuit suitable for proper operation.

It is set to the range 0-25% Oxygen / 4-20mA (0% Oxygen = 4mA, 25% Oxygen = 20mA.)

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 aforementioned terminals are in open circuit!

2.4 Operation

Before turning on the SIL O2 analyzer for the first time or after disconnecting the sensor for maintenance / replacement, make sure that a working sensor is connected. Otherwise, the SIL O2 analyzer will go into failure mode, with the red error indicator on and the RL3 relay disabled. As the fault circuit performs a cyclic check every 30 seconds or so. When the sensor is connected, resetting the red indicator and relay 3 occurs automatically, but it is advisable to power off the system to allow the sensor to be disconnected / reconnected under normal circumstances, if possible.

Turn on/apply power to the SIL O2 Analyser.

When operating under normal process/system conditions, the SIL O2 Analyser will give a digital readout of the measured Oxygen level (from the Sensor in the process).

This measurement is converted into a 4-20mA output signal proportional to the Oxygen being measured.

If an Alarm level even occurs, the relevant programmed output device will operate (Relay or Transistor) and the ineterface circuit to the user equipment will be interrupted. For further alarm or fault events and their conditions, please see the troubleshooting section at the end of this Manual.

2.4.1 Calibration Procedures

The SIL O2 Analyser and Sensor unit requires periodic calibrations performing, the timing between such calibrations being determined by the application and process requirements.

Typically, a periodic calibration check would reveal if any calibration adjustment is necessary. The SPAN calibration point of 20.9% O2 (Air) is the important setting and typically, if calibration adjustment is required, this is the value that would be adjusted. This adjustment can be made ussing ambient air as the calibration standard or, for greater accuracy, certified cylinder gas at 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.

Note: Calibration Adjustment procedure.

The displayed number change starts with the digit to the far right of the decimal point. Press and hold the Up or Down buttons to change the reading. This gives an accelerated adjustment. More accurate adjustment is achieved by pressing the Up or Down button at one press (press release, release of press, etc.). When the display reads 20.9%, the calibration of the range is complete

I s s u e 3 0 - 11- 2018

2.4.2 Setting the Zero point.

This must be done each time a new sensor is installed before a span calibration is performed.

Subsequently, a zeroing can be performed periodically as needed.

A zeroing operation requires the application of a zero oxygen gas to the sensor, typically nitrogen (minimum quality <100 ppm). Note: Accessing the Zero function when the sensor is in ambient air (20.9% O2) will result in an error / fault condition.

Depending on the type of sensor installed, zero gas must be applied through a process fitting or calibration adapter, and be sure to leave a free exhaust at a suitable location so that the sensor does not become pressurized.

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 oxygen is present in the measured gas.

• ZERO mode is activated after pressing the UP and DOWN button simultaneously for more than one

second. As an acknowledgment of receipt, the A3 LED flashes. An adjustment of the indicated value is made by pressing the UP or DOWN buttons individually as required.

• The change starts with the digit to the right of the decimal point. (00.0) Press and hold the Up or Down

buttons to change the displayed reading. This allows an accelerated adjustment. Accurate adjustment is achieved by pressing the Up or Down button at one press (press release, release of press, etc.). When the display reads 0.0% O2, the setting is complete. By simultaneously pressing the two buttons or a delay of 20 seconds, the ZERO operating mode ends.

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:

• The SIL 2 analyzer should only be calibrated at approximately 20.9% oxygen.

• If an ambient air calibration is performed, it is recommended to confirm the oxygen level with a

certified portable oxygen analyzer prior to calibration.

• If a zero setting is made first, then after the end of the zero operation mode, the Span mode is

automatically activated after a delay of 20 seconds.

• If A Span only calibration is required, then just press the UP or DOWN buttons individually to

increase or decrease the displayed value of oxygen to read 20.9. Note: Ensure the Sensor is in

20.9% oxygen when you do this!

• Calibration complete.

3. Operational safety and maintenance instructions.

If it is assumed that safe operation is no longer possible, the device must be taken out of service and protected against accidental use. The reasons can be:

visible damage to the device

failure of the electrical function

long shelf life at temperatures above 85 ° C

Transport damage

Before the device can be put back into service, a professional routine check must be carried out in accordance with DIN EN 61010, part. 1. This examination must be carried out by the manufacturer. Repair work on Ex devices may only be carried out in accordance with § 9 of Ex. (Elex V).

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.

3.2 Wire break

When manually disconnecting the sensor (for example for maintenance) or following a break in the sensor connection cable, the SIL O2 Analyzer RL3 fault relay switches off and interrupts the safety circuit.

The red fault indicator will illuminate on the SIL O2 analyzer and the 4-20 mA analog output will reach a constant high value of 22.0 mA. At the same time, the setpoint relays RL1 and RL2 will be deactivated.

When the sensor is reconnected or the cable fault is corrected, the RL3 relay automatically resets after about 30 seconds and the red LED goes out. At the same time, RL1 and RL2 are reset according to their setpoints and the measured gas level. See also note on page 13 of this manual for reset requirements under specific conditions.

3.3 System faults

A number of internal faults in the SIL O2 analyzer generate a fault output and interrupt the safety circuit. In some cases, cycling the power supply of the SIL O2 analyzer may be sufficient to remedy the problem. Otherwise, please contact Ntron for assistance.

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. This can

occur if a Zero calibration is performed when the Sensor is in ambient air. If this occurs, the Red fault LED will illuminate and the Analyser display and Analogue output will read an over-range value. The

Alarm level LED’s may also illuminate. This may also occur if a genuine overrange event takes place,

with gas containing more than 25% O2 being applied. (25%O2 displayed)

Solution: re-calibrate with Nitrogen gas (Zero) and then re-calibrate at the Span point of 20.9%.

• Action: Powering on the Analyser with no sensor connected or a wire break to the sensor.

Problem: If the sensor is disconnected, this would ordinarily cause relays R1, R2 and R3 to de-

energise. Analyser display and Analogue output will read a fault value. (28% O2 displayed and 22mA output)

Solution: Check Sensor wiring and connect the sensor to the Analyser. After approximately 30

seconds, the Analyser will reset and the Red LED should extinguish.

• Action: Unable to perform a Span calibration.

Problem: The Analyser cannot be adjusted to display 20.9% O2 during Span calibration.

Solution: The Sensor may be approaching end of life or has been damaged and cannot generate

sufficient output. Replace the sensor

Alarm level LED’s may or may not be illuminated depending on configuration.

• Action: Alarm Level LED’s (Yellow) illuminated.

Problem: Alarm level LED’s illuminated.

Solution: Genuine Oxygen level alarm event.

Incorrect sample gas levels being applied to the Sensor or incorrect alarm level settings are configured within the Analyser. If this is not expected then check sample gas with independent instrument gas/and/or re-configure Analyser Alarm setpoints. This will require interface with PC based software.

21 | P a g e R e v . 1 .1

I s s u e 3 0 - 11- 2018

• Action: Red Fault LED illuminated when none of the above conditions are present.

Problem: Analyser in fault condition. Analyser display and Analogue output will read a fault value.

(28% O2 displayed and 22mA)

Solution: Internal Analyser electronics or programming fault. Try Power On/Off cycle to reset.

If fault does not clear then seek further assistance.

Problem: No Analyser display (Blank)

Solution: Analogue output circuit is broken or interrupted. Investigate and repair.

3.4.1 Possible Sensor Faults

Applicable to all sensor types (OC-25, OC-26, OC-200)

Problem:. SIL O2 Analyser will not calibrate (Cannot be set to 20.9%)

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:. SIL O2 Analyser reads Zero (0.00)

Solution: Actual low Oxygen measurement. Sensor wires have been shorted together, damaging the Sensor.

Verify the Oxygen level by other means. Check the Sensor output signal. Replace Sensor as necessary.

3.5 General Maintenance

Establish a periodic checking and maintenance routine in line with the requirements for Safety Instrumented Systems. See the Ntron SIL O2 Analyser Technical and Safety manual for further details.

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. The ingress of such contaminants should be investigated.

Ensure all wiring to the SIL O2 Analyser is secure and in good condition, paying particular attention to the security of the connection terminals if the user enclosure is subject to vibrations.

There are no user serviceable parts within the SIL O2 Analyser. If any malfunction is detected, mechanical or electrical, the SIL O2 Analyser should be immediately removed from service following the correct protocols.

The Sensor used has a finite life span. The Performance of the Sensor is verified by calibration check and this should be performed according to the protocols required by the safety system. Replacement of the Sensor is necessary when it does not meet the required performance levels.

During operation life, the Sensor should be kept clean of contaminants. It can be wiped with a soft damp cloth. Observe the restrictions regarding potential static charges as detailed on the Sensor Installation Instruction Documents found in the appendix to this manual.

When removing Sensors from their process installation for replacement or other service requirements, observe the following points.

• Ensure any and all system shut down protocols are followed as applicable.

• Do not disconnect the Sensor from the connecting cables whilst the system is operating or is

‘Live’.

• Ensure the process being measured is shut down or the Sensor connection is isolated by any

intermediate valve mechanism if fitted.

• Always remove the Sensor connector before unscrewing the OC-25/OC-200 Sensors or

unclamping the OC-26 Sensors from their process fittings

• Block off the exposed process connection if required during the period the Sensor is disconnected.

• Protect the disconnected Sensor cable from damage during the period the Sensor is disconnected.

Oxygen sensors for hazardous areas are especially designed to conform

to national and international standards governing risks of explosion and

certificates for each type are issued by an approved organisation or

notified body. Be careful ! A certification number followed with “X” or a

“U” requires specific conditions for use.

The Specific Condition of Use for the sensor types listed below is;

Possible Electrostatic Risk-Do not charge by Rubbing and do not

clean with Solvent

STORAGE

The sensor should be stored in a cool dry place. HANDLING WARNINGS

Do not expose open end of sensor housing to liquids, particulates,

grease, or oil.

Do not touch top of sensor within open end of sensor housing.

Do not allow vacuum grease to coat open end of sensor.

Do not expose sensor to sudden mechanical shocks. INSTALLATION & CALIBRATION

Remove the sensor plug from the old sensor.

Remove the old sensor by unscrewing counter clock wise.

Install the replacement sensor threading on clockwise.

Fully tighten the sensor housing.

Re-connect the sensor plug.

Calibrate the analyser to the new sensor. Note: The system must not be put back on-line until the analyser has

been calibrated to the new sensor. ELECTRICAL CERTIFICATION Sensor Type’s OxyProbe
