1 Safety Regulations

1.1 Correct use

The PrimaX Gas Transmitters are fixed gas transmitters for measuring toxic or combustible gases and for monitoring oxygen deficiency, excess or inerting. They are suitable for outdoor and indoor applications without limitations, e.g. offshore industry, chemical and petrochemical industry, water and sewage industry. The signal of the transmitter can be used in combination with MSA control units for further actions in safety or non safety applications, e. g. MSA SUPREMA, Gasgard XL, 9010/9020.

The two versions of the gas transmitter are delivered either in a flameproof or in a intrinsically safe enclosure. The electrical parts and interfaces have the same basic functionality.

It is imperative that this operating manual be read and observed when using the device. In particular, the safety instructions, as well as the information for the use and operation of the device, must be carefully read and observed. Furthermore, the national regulations applicable in the user's country must be taken into account for a safe use.

WARNING!

This product is supporting life and health. Inappropriate use, maintenance or servicing may affect the function of the device and thereby seriously compromise the user's life.

Before use the product operability must be verified. The product must not be used if the function test is unsuccessful, it is damaged, a competent servicing/maintenance has not been made, genuine MSA spare parts have not been used.

Alternative use, or use outside this specification will be considered as non-compliance. This also applies especially to unauthorised alterations to the product and to commissioning work that has not been carried out by MSA or authorised persons.

1.2 Liability Information

MSA accepts no liability in cases where the product has been used inappropriately or not as intended. The selection and use of the product are the exclusive responsibility of the individual operator.

Product liability claims, warranties also as guarantees made by MSA with respect to the product are voided, if it is not used, serviced or maintained in accordance with the instructions in this manual.

1.3 Safety and Precautionary Measures to be Adopted

Safety Regulations

WARNING!

The following safety instructions must be observed implicitly. Only in this way can the safety and health of the individual operators, and the correct functioning of the device, be guaranteed.

• The device described in this manual must be installed, operated and maintained in strict accordance with their labels, cautions, instructions, and within the limitations stated.

• The device is designed to detect gases or vapours in air.

• If a device with a combustible sensor is exposed to vibrations, calibration shall be done in sufficient short intervals until it is verified that the device is not affected by the vibration stress.

• Do not mount the sensing head in direct sunlight as this could cause overheating of the sensor.

• The device must be installed with the sensor inlet pointing downwards to avoid clogging of the gas inlet by particles or liquids.

• Electrochemical sensors are sealed units which contain a corrosive electrolyte. Should a sensor develop leakage, it must be immediately removed from service and disposed of properly. Caution

PrimaX

Safety Regulations

must be exercised so that the electrolyte does not contact skin, clothing or circuitry otherwise personal injury (burns) and/or equipment damage may result.

• The only absolute method to ensure proper overall operation of the device is to check it with a known concentration of the gas for which it has been calibrated. Consequently, calibration checks must be included as part of the routine inspection of the system.

• As with all devices of these types, high levels of, or long exposure to, certain compounds in the tested atmosphere could contaminate the sensor. In atmospheres where the device may be exposed to such materials, calibration must be performed frequently to ensure that the operation is dependable and display indications are accurate.

• The device must not be painted. If painting is done in an area where a device is located, care must be exercised to ensure that paint is not deposited on the sintered metal flashback arrestor in the gas sensor inlet, if so equipped. Such paint deposits would interfere with the gas diffusion process.

• Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual. Failure to do so may seriously impair instrument performance. Repair or alteration of the device, beyond the scope of these maintenance instructions or by anyone other than an authorised MSA service personnel, could cause the product to fail to perform as designed.

• The device is designed for applications in hazardous areas under atmospheric conditions.

• For correct measurements, the combustible gas sensors require an oxygen concentration greater than 10 Vol%. Oxygen enriched atmospheres, greater then 21 Vol%, can affect the measurement and the electrical safety of the device.

• The response time of the device will be increased by significant dust deposits on the Sensor. Checks for dust deposits must be done at regular intervals.

• Catalytic combustible gas sensors may produce low or zero response to combustible gas after exposure to substances as Silicon, Silane, Silicate, Halide and compounds containing Fluorine, Chlorine, Iodine or Bromine.

• Catalytic sensor: After exposure of gas above the measuring range, the sensor has to be immediately calibrated / adjusted, independent of the calibration interval. In the case of an adjustment the sensitivity of the sensor has to be rechecked again after 24 hours.

• In case of very high flammable concentrations >100%LEL the device is able to lock all outputs (LOC). This function shall be used for standalone applications according to ATEX requirements.

• Catalytic sensor: If the PrimaX is operated in combination with a control unit and (LOC) is deactivated on the PrimaX, the control unit has to ensure the latching after the measuring range was exceeded.

• Catalytic sensor: Before a reset of an over range (LOC) indication is done it shall be verified that the gas concentration is below full scale.

• Toxic gases: If the measuring range is exceeded, sensor life time can be reduced or the sensor might need a recovery phase.

• Used sensors have to be disposed of in an environmentally compatible way.

• At signal underrange between -1.25 % and -10 % of the measuring range the 4 - 20 mA output is set to 3,8 mA. At signal underrange of more than -10 % of the measuring range the 4 - 20 mA output is set to the error state (2 mA). To avoid a delayed alarm activation, a calibration should be done when the output current is set to 3,8 mA and "LO" is shown on the display persistently.

• The lowest range which is suitable for the alarm thresholds should be selected for toxic gases.

• To compensate for possible deviations during measurement of flammable gases a calibration factor of 1.05 has to be applied when using the CalGard for remote calibration (see chapter 8.3 "Remote Calibration")

4.3 Calibration

WARNING!

The test gases used for calibration are possibly posing a health risk. Proper ventilation or extraction has to be ensured.

General

The calibration must be done at regular intervals in accordance with applicable national and regional regulations.

The device is calibrated at the factory. Nevertheless, it is recommended to recalibrate the device after installation. The frequency of calibration depends on the duration of use and the chemical exposure of the sensor. New sensors must be calibrated frequently until it is clear from the calibration data that they have stabilised. Suitable regulators and pipes for calibration must be used.

Operation

A calibration cap is recommended for sensor calibration, flow rate 1l/ min (± 20%).

Connect power to the device at least one hour before attempting a calibration.

Carry out the calibration during commissioning as well as at regular intervals. This ensures optimum operation of the sensor.

It is recommended that all calibration components are connected before starting a calibration as it is necessary to apply test gas to the device during a countdown.

PrimaX

Operation

When monitoring flammable gas in safety related applications the PrimaX must be calibrated with a known concentration of the gas being monitored.

The lower explosive limits (LEL) of the gases and vapors in the following example were taken from EN 60079-20-1. Local regulations may specify different LEL values; always ensure the correct values are used.

It is recommended that the PrimaX zero is calibrated using clean air, free of measuring gas, and calibration gas of approximately 50 % of measuring range (comb. and TOX) in air of the gas being monitored. The recommended calibration gas for oxygen is 50% of measuring range, but for a measuring range 0-25 vol% O

Calibration example for Methanol

Methanol calibration gas concentration being used = 3,5 Vol% Methanol volume concentration for 100%LEL = 6,0 Vol% Methanol calibration gas concentration in %LEL

, the device can be calibrated using 20.9 vol% O2.

For oxygen a zero calibration with gas is not required, it is performed internally.

3,5 Vol% CH

Calibration Procedure

The calibration can be performed as a manual or an automatic calibration (→ M-04).

Automatic Calibration (automatic): a countdown is displayed. After the countdown the value is

measured and displayed. When the value is stable the current value is selected automatically.

Manual Calibration (manual): the measuring value is displayed. When the value is stable press

ENTER to select the current value.

Waiting for calibration gas

After starting any calibration step, calibration gas (zero or test gas) must be applied until calibration step is finished.

4.7 Optional HART Module and Relay HART

Introduction

"HART" is an acronym for Highway Addressable Remote Transducer. The HART Protocol makes use of the Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital communication signals at a low level on top of the 4 - 20 mA.

The HART Protocol provides two simultaneous communication channels: the 4 - 20 mA analog signal and a digital signal. The 4 - 20 mA signal communicates the primary measured value (in the case of a field instrument) using the 4 - 20 mA current loop. Additional device information is communicated using a digital signal that is superimposed on the analog signal.

PrimaX is registered with the HART foundation and can be accessed at http://www.hartcomm.org/

The device is available with an optional HART module or a module with HART and Relays for alarm and failure. It uses the HART Protocol Revision 7 and can only communicate with HART Masters who support revision 7 or higher.

Operation

22 mA

The following HART functions are also available:

ZERO SPAN Calibration / Oxygen Calibration; ZERO Calibration; Sensor Exchange; LCD/LED Test; Loop Test; Range setup; Reset alarm; Readout all measured data and information.

Relative response factors of tested gases with reference to Propane

For the gases or vapours shown in the tables of this chapter the response curves have been tested according to EN 60079-29-1:2007. If the LEL of a substance was not listed in EN 60079-20-1:2010, the LEL has been taken from the Chemsafe data base (Dechema, Frankfurt). Due to legal requirements other locally used LEL values might be mandatory. It is highly recommended that the gas detector is exposed to clean air when calibrating the zero and a mixture of the target gas in air with a concentration of approximately 50% LEL. If calibration with the target gas is not possible a reference calibration can be performed with 0.85 % (v/v) Propane C data given in the table of this chapter. These values are only valid for new sensors and, unless otherwise stated, they refer to an ambient temperature of 20°C. If using a reference gas to calibrate the gas detector the displayed values may vary by up to +/- 20% from the target gas concentration.

8.1 Calibration Cap

Using calibration cap allows span gas calibration procedure to be accurate in windy environmental conditions.

The calibration cap is pushed on to the front of the sensor and is sealed by an O- ring. The surface area S < 20 cm

Fig. 13 Calibration cap

The calibrating cap must be removed after completing the calibration!

The gas is supplied via either of the gas inlets by means of suitable flexible tube.

8.2 Sensor Gard

WARNING!

Accessories

Fig. 14 Sensor gard

The sensor gard should be fitted at all times except when using the flow through adapter or duct mount kit.

Ambient weather condition can affect the gas mixture inside of the sensor gard. Use sensor gard for functional test only. Calibration cap is recommended for sensor calibration.

Using the sensor gard will extend the response time, depending on the gas flow rate.

Gas flow rate: 1,0 l/min

PrimaX

8.3 Remote Calibration

Fig. 15 PrimaX with CalGard

The CalGard stainless steel remote calibration adaptor provides reliable operation of remotely installed gas detectors working under harsh environmental conditions. Additionally, the CalGard allows remote verification ("bump test") or instrument calibration of gases listed later in this section and oxygen via a hose connection in the presence of wind speeds up to 6 m/s.

In normal measurement operation, the ambient air passes through the air vents into the remote calibrator directly to the sensor (diffusion operation). During a bump test or instrument calibration, the test gas is supplied to the sensor via the hose connection at the bottom of the CalGard. An integrated mechanism prevents the dilution and dispersion of test gas otherwise caused by external influences, such as wind. This allows a fast response from the sensor to the applied test gas.

Once calibration is complete, the air inlet reopens to allow the monitoring of ambient air for gas without the need for further user intervention.

Installation

For correct operation, PrimaX and CalGard must be used in a vertical position (hose connection pointing downwards). The CalGard remote calibration adaptor can be attached to the sensor by screwing on the thread of the detector.

Accessories

The tube connector is adapted for tubes with an inner diameter of 5 mm.

In general the hose should be as short as possible in order to:

• Minimise the gas volume needed to flush the tube

• Reduce external influences (e.g. temperature shift, pressure, etc.)

• Minimise the lead time

Hose material should be adapted to the applied test gas, have no absorptive or adsorptive properties and should be made from inert material such as teflon or polyethylene.

When using the CalGard in the hazardous area, a conductive hose must be used.

The free end of the test gas tube must be closed if no test gas is applied. This is to prevent gas or air passing through the tube to the sensor, distorting the measurement or in the reverse pressure conditions, the ambient atmosphere escapes from the sensor at the free end of the tube.

PrimaX

Accessories

To ensure proper function the CalGard remote calibration adaptor must be kept dry and free of any contaminants, e.g. dust particles. Regular visual checks are recommended. Any contaminants must be removed by blowing them off with clean, oil-free compressed air or with a dry brush. Ensure that the air entrances are kept free from any coating, e.g. paint, grease or similar.

Operation

Calibration procedure can be carried out as described in chapter 4.3 "Calibration" of this manual

To compensate for possible deviations during measurement of flammable gases a calibration factor of

1.05 has to be applied.

Example: Calibration for methane.

Apply 40 %LEL methane and adjust to 1.05 x 40 = 42 %LEL

When using the CalGard for a remote calibration, the response time of the system increases depending on the length of the test gas tubes used. If the calibration is done automatically, set the calibration setup (menu: M04) with sufficiently long countdown times for zero gas and calibration gas.

Example: When using a 10 metre long tube with an internal diameter of 5 mm and applying a gas flow of 1 litre/min, the test gas takes a minimum of 20 sec to reach the CalGard remote calibration adaptor. For safe flushing of CalGard, an additional 10 seconds has to be added to this calculation.

If the CalGard is being used with a control system (i.e. SUPREMA), please ensure the manual for the controller has been read and understood.

The pressure in the test gas tube increases with rising test gas flow rates. A flow rate of 1500 ml/min results in a pressure up to 600 hPa. This has to be considered if a flow meter is used which is affected by the media pressure.

8.4 Flow Through Adapter

Fig. 16 Flow through adapter

The flow through adapter is for use with a pumped sampling system.

Gas inlet/outlet thread: 1/8” NPT Gas flow rate: 1.0 l/min

Using the flow through adapter will extend the response time, depending on the gas flow rate.

8.5 Duct Mounting Kit

Accessories

Fig. 17 Duct mounting kit

Gas monitoring in air ducts can be performed by means of this duct mounting kit. When installing, the direction of flow inside the duct must be towards the baffles.

The sensor can be calibrated via the gas calibration port, provided the duct is free of all gases to which the sensor will respond. If the duct cannot be gas free, the sensor must be removed from the duct during calibration.

The calibration port must be sealed again with the locking cap after calibration has been carried out.

Calibration should only be carried out with the calibration port if the air velocity is < 5 m/s in the air duct.

PrimaX

The performance of the duct mounting kit depends on various parameters and has to be checked before usage. The kit was not part of the compliance test.

8.6 Pipe Mounting Kit

The PrimaX can be mounted vertically by fastening its back plane using two screws and washers. Additionally, a pipe mount kit allowing the PrimaX to be fixed to pipes or poles is available as an accessory.

The kit consists of:

• one universal mounting plate

• one retaining plate for pipes with a diameter of 20 – 30 mm

• one retaining plate for pipes with a diameter of 30 – 50 mm

• two tightening straps for pipes with a diameter of 50 – 150 mm.

Check zero gas and span gas, see settings (M-03) and flow rate, repeat calibration, otherwise replace sensor

If an error is detected, the error code E, followed by a numeric code and a short description, will be displayed.

In this case the normal operation mode of the device will not respond to gas and the output signal current will be the ERROR value (default 2mA).

Latched Hardware/Software Error

E-01 – E-29 latched errors, press any key for reset device

E-30 – E-49 non-latched errors, self-deactivating

Appendix

If an error code is displayed, the normal operation of the device is not possible.

If the error code is still shown after a reset, the device could be defective.

The removal of the hydrogen cyanide and chlorine sensors will not trigger the E-28 sensor error message.

For additional support please contact MSA Service.

Sensor errors (E-20 – E-29) could be cleared by checking if the sensor is well connected, or by changing the sensor, or also by resetting the device.

10.4 Timeout

The automatic calibration has a timeout of 4 minutes. The manual calibration has a timeout of 60 minutes (M-01, M-02). Any test procedure (M-06, M-07, M-13 and the sensor exchange M-05) has a timeout of 15 minutes. Anywhere else in the menu the timeout is 2 minutes, if no button is pressed.
