For Your Safety

For Your Safety

The lines highlighted by grey shading contain appropriate instructions for the commissioning, service, inspection and testing the operability, especially considering the safety.

Strictly follow the Instructions for Use

Any use of the transmitter requires full understanding and strict observation of these instructions.

The transmitter is only to be used for purposes specified here.

Maintenance

The instrument must be inspected and serviced regularly by trained service personnel.

We recommend that a service contract be obtained with DrägerService and that all repairs also be carried out by them.

Only authentic Dräger spare parts may be used for maintenance.

Observe chapter "Maintenance".

Intended Use

The transmitter PEX 3000 is intended to be used for fixed installed continuous monitoring for mixtures of flammable gases and vapours with air under atmospheric conditions. The full scale range is 100 % or 10 % of the lower explosive limit (LEL). The transmitter is connected to a suitable controller unit by means of a 3-core-cable, the measurement signal during normal operation is between 3.8 and 20.5 mA.

The Transmitter PEX 3000 type XTR 0090 and XTR 0091 (Remote-Version) is intended to be used in combination with a remote Dräger sensing head, e.g. Polytron

SE Ex PR M (100 % LEL) or Polytron SE Ex LC M (10 % LEL).

As the operation of the PEX 3000 in combination with the mentioned remote sensing heads does not really differ from the operation of the PEX 3000 with built-in sensors, they are not explicitly considered in these instructions for use. Likewise also the operation of further housing types, e.g. of the types XTR 0001 and XTR 0011

(drilling templates see page 29) is not explicitly described.

The transmitters must not be used at ambient temperatures lower than –40 o

C.

For the transmitters PEX 3000 type XTR 0000, XTR 0001, XTR 0010, and XTR 0011 the maximum ambient temperature is depending on the temperature classes and is

40 o

C for temperature class T6, 55 o

C for temperature class T5, and 65 o

C for temperature class T4.

For the transmitters PEX 3000 type XTR 0090 and XTR 0091 the permissible maximum ambient temperature is 65 o

C generally.

The transmitter is approved acc. to the device categories II 2G and II 2D and can be operated in hazardous areas zone 1 and zone 2 as well as zone 21 and zone 22.

Observe installation instructions.

Not to be used in oxygen enriched atmospheres.

In conjunction with a suitable controller unit with pre-adjusted alarm thresholds acoustic and visible alarm devices or automatic countermeasures can be activated before the detected gases or vapours can form dangerous flammable mixtures with air.

Hints for safe use

Only certified sensors or sensing heads are allowed to be connected to the terminals br/br, ge/yw, and sw/bk.

In potentially gas-explosive areas (zones 1 and 2) the energised transmitter is only allowed to be opened for maintenance purposes.

In potentially dust-explosive areas (zones 21 and 22) there is no explosion protection if the energised transmitter is opened. The Ex area has to be temporary declassified if necessary!

Before closing the transmitter make sure the atmosphere is free of dust.


Intended Use

Page 5 of 42

Intended Use

The following conditions for safe use have to be observed:

1. Basically, the measuring principle of heat of reaction which is based on the catalytic oxidation of a flammable gas, is ambiguous because at high gas concentrations there is not enough oxygen in the sensor necessary for the oxidation process. So the measuring signal decreases at high gas concentrations and even can lead to measuring signal within the measuring range again. A connected controller must be operated with alarm devices, outputs, and alarm thresholds operating as latched if the measuring range is exceeded.

2. The measuring principle of heat of reaction needs a minimum oxygen concentration of 12 % by vol., otherwise the measuring values will be too low because of oxygen deficiency.

Measuring function for the explosion protection acc. to 94/9/EC

In the 1st supplement to the EC-type examination certificate TPS 04 ATEX 1 003 X the transmitters PEX 3000, type XTR 00x and XTR 009x, with Ex-sensor PR M (partno. 68 09 225) have been approved in respect to the measuring function for explosion protection acc. to EN 61779 part 1 and part 4, for the following gases and vapours:

Methane, Propane, Acetone, Ammonia, Petrol 065/095 (FAM Standard Gasoline),

Benzene, 1,3-Butadiene, n-Butane, n-Butyl acetate, Cyclopropane, Diethyl ether,

Dimethyl ether, Ethanol, Ethene (Ethylene), Ethyl acetate, Ethylene oxide, n-Hexane,

Methanol, Methyl ethyl ketone (MEK), n-Nonane, n-Octane, n-Pentane, i-Propanol,

Propene (Propylene), Propylene oxide, Toluene, and Hydrogen.

Especially the PEX 3000 has undergone a safety related assessment concerning the internal software and digital techniques, based on the harmonized standard

EN 50271.

Important remark

Although the transmitter has been factory-tested before delivery, the commissioning after installation must include the zero- and span-adjustment.

The commissioning has to be terminated by a function test of the complete gas detection system.

Installing Transmitter

Mounting

Orientation: The measuring signal of the transmitter is depending on the inclination.

The transmitter must be mounted such that the sensor’s gas entrance area of the sensor is pointing downwards. If to be mounted at the ceiling a mounting bracket must be used.

— Install transmitter in vertical position at a location with little vibration and maximum temperature stability (no direct sun light) in the vicinity of a possible leak.

— Consider the complete scope of environmental conditions influencing the transmitter Avoid external influences such as splashing water, oil, corrosive aerosols

(salty fogs) etc. and the possibility of mechanical damage.

— Leave at least 30 cm free space beneath the transmitter to provide accessibility for calibration work.

Remark

Certain substances in the atmosphere to be monitored may impair the sensitivity of the sensors (Ex-Sensor PR M or Ex-Sensor LC M) installed in the transmitter:

The following substances are known at present: a) polymerizing substances such as acrylo nitrile, butadiene and styrene, b) corrosive compounds such as ammonia and halogenated hydrocarbons (releasing halogenes such as bromine, chlorine or fluorine when being oxidised), c) catalyst poisons such as sulphurous and phosphorous compounds, silicon compounds, and metal-organic vapours.

The sensors used are based on measuring elements (pellistors) which are poisonresistant and so have a longer lifetime than conventional sensors if catalyst poisons occur. However there is still the rule to shorten the test or calibration intervals if catalyst poisons are expected to occur in the atmosphere to be monitored.

Pay attention to ventilation!

— Always arrange sensing head and transmitter in air flow between possible leak or collection point and possible source of ignition.

Pay attention to the density of gas!

— In case of gases, the density of which is lower than that of air, such as hydrogen, methane or ammonia the transmitter or sensing head must be located above a possible leak or at the highest points at which major concentrations of gas may be found.

— In case of gases and vapours with a density greater than that of air, the sensing head or transmitter must be installed beneath a possible leak or at the lowest points at which such gases and vapours may be present.

Internal wiring in the transmitter’s enclosure

Connect the individual conductors (conductor length min. 55 mm, 5 mm insulation stripped) to the spring terminal clamp so that it is short. Use ferrules in case of stranded cables.

— For the wiring of power supply and signal loop cables only cables with a crosssection of at least 0.75 mm

2

may be used. Cables with a cross-section of

0.5 mm

2

may only be used if the are equipped with an isolating ferrule (e.g.

Zoller+Fröhlich, Type V3AE0005, V3AE0037 or equivalent). This ensures an IPrating of IP 30 if the transmitter housing is opened for maintenance purposes.

Only Type XTR 0090 and XTR 0091:

— For the wiring between transmitter and sensing head (e.g. Sensing Head SE Ex

PR M) use only cables with a cross-section of at least 0.75 mm

2

. Cables with a cross-section of 0.5 mm

2

may only be used if the are equipped with an isolating ferrule (e.g. Zoller+Fröhlich, Type V3AE0005, V3AE0037 or equivalent). This ensures an IP-rating of IP 30 if the transmitter housing is opened for maintenance purposes.

Remark:

Blank cables must not stick out the spring terminals. The method of explosion protection during maintenance is based on the condition that it is not possible to contact blank cable parts by a probe of 2.5 mm diameter

(definition of IP 30).

Calibrating transmitter

For this chapter:

— Mentioning Type XTR 0000 also includes type XTR 0001 as well as the transmitters type XTR 0090 or XTR 0091 with remote sensing head SE Ex PR M

(100 % LEL).

— Mentioning Type XTR 0010 also includes type XTR 0011 as well as the transmitters type XTR 0090 or XTR 0091 with remote sensing head SE Ex LC M

(10 % LEL).

Zero point adjustment

To enter the calibration menu press the key l for more than one second but less than 3 seconds. The display shows a flashing point on the right bottom indicating the calibration mode.

●

●

Navigate by means of keys q or l until the display shows ZE (“ZEro“) and enter the menu by pressing the keys ( q + l ). The output signal is set to 3.4 mA to signal the calibration procedure mode to the controller unit.

Apply zero gas to the sensor – without calibration adapter:

Ensure that the transmitter is in clean ambient surroundings (no flammable gases or vapours present), or with calibration adapter:

Supply clean air at a flow rate of approx. 0.5 L/min via the calibration adapter.

— The transmitter’s display shows the currently measured gas concentration which in general is slightly different from zero. Negative values down to “–9“ % LEL or

●

●

“–.9“ (type XTR 0010) are displayed.

Wait until the reading has stabilised (max. 3 minutes) and press keys ( q + l ). By this the current sensor signal is converted into an up-dated zero point also shown on the display (ideally "0“).

Press keys ( q + l ) to save the up-dated zero point and to terminate the zero adjustment function.

Remark:

After a sensor replacement the zero point might be misaligned so much that the display shows “--“. In this case press keys ( q + l ) to save preliminary zero and again follow the above zero adjustment procedure.

●

●

Press keys ( q + l ) to exit this function. The display shows ZE again.

Press key q to switch back to the measurement mode or press key l to perform the sensitivity adjustment.


Page 17 of 42


Sensitivity adjustment

Before sensitivity adjustment the zero point must be adjusted!

● Navigate by means of keys q or l until the display shows SP ("SPan“) and enter the menu by pressing the keys ( q + l ). The output signal is set to 3.4 mA to signal the calibration procedure mode to the controller unit.

— The display shows the span gas concentration used during the previous calibrati-

● on procedure in % LEL.

By means of the keys q or l the concentration of the currently used span gas can be adjusted between 20 and 99 % LEL in steps of 1 % LEL.

— The display of type XTR 0010 shows a decimal point, so the gas concentration of the currently used span gas can be adjusted between 2.0 and 9.9 % LEL in steps of 0.1 % LEL.

— Pressing the keys for longer activates a repeat function.

Recommended span gas concentration:

Transmitter

Typ XTR 0000

Typ XTR 0010

Full scale deflection

100 % LEL

10 % LEL

Span gas concentration

30 to 70 % LEL

3 to 7 % LEL

Attention:

The span gas must be a mixture of the gas to be monitored in air!

Mixtures with nitrogen are not suitable!

●

●

Press ( q + l ) and – depending on the current transmitter type (see table) – apply the recommended gas concentration at a flow rate of ca. 0.5 L/min via the calibration adapter.

Wait until the reading has stabilised (max. 3 min) and press keys ( q + l ) to calculate the necessary internal amplification.

The display shows the measured value with the newly calculated amplification factor, which however has not been saved yet. So the original amplification factor will be restored if the calibration menu is automatically exited by waiting for longer than four minutes.

Remark:

After sensor replacement the internal amplification of the transmitter can be so high that the measured concentration cannot be displayed. The display will show then “99” or “9.9”. Nevertheless press keys ( q + l ) to calculate the necessary internal amplification, save it, and repeat the sensitivity adjustment.

● Press keys ( q + l ). The newly calculated amplification factor is finally saved. The display shows a reference value proportional to the sensitivity of the sensor (constantly amplified bridge signal). If this value is lower than 10 it is displayed with decimal point.

— The true sensitivity of the sensor in mV per % LEL can be obtained by multiplying the reference value by a factor 2 and dividing it by 100 (or with the type XTR 0010 divide it by 10), e.g.:

— If after sensitivity adjustment of the type XTR 0000 by means of 52 % LEL propane a reference value of 45 is displayed, so the true sensitivity of the Ex-sensor PR M for propane is 45 * 2 / 100 = 0.9 mV/% LEL.

Page 18 of 42


— If after sensitivity adjustment of the type XTR 0010 by means of 4.4 % LEL ethanol a reference value of 32 is displayed, so the true sensitivity of the Exsensor LC M for ethanol is 32 * 2 / 10 = 6,4 mV/% LEL. This value is 5-fold higher than with the Ex-sensor PR M because of the internal amplification of the Ex-sensor LC M.

● The reference value and/or the true sensor sensitivity should be recorded for test purposes.

Remark:

If the reference value is less than half value recorded during commissioning or if the measured value does not stabilise within 3 minutes, the sensor is defective and should be replaced (see page 22).

●

●

Press keys ( q + l ) to exit this function.

Press key q twice to switch back to the measurement mode. The flashing point on the right bottom is deactivated.

Following completion of calibration:

— The display shows the current gas concentration in % LEL and the transmitter’s

4 to 20 mA-output is proportional to the current gas concentration in % LEL.

● Observe the atmosphere is free of dust and re-install the upper section of the housing by means of the four screws..

Shut downs

In the event of shut-downs, e.g. when performing maintenance and inspection work, the transmitter is ready for use again after approx. 10 minutes (sensor warm-up time) following a renewed switch-on of the system.

● Calibrate the transmitter again if necessary.

Use of dust filter

Type XTR 0000:

A dust filter can be used with the Ex-sensor PR M (see order list, part-number

68 10 537).

This is simply pressed into the opening of the sensor in front of the sinter disk and is self-clamping. This dust filter will increase the sensor’s response time only slightly.

There is nearly no influence on the sensor’s sensitivity by the dust filter.

If a dust filter is used it has also to be used during the calibration procedure. It is recommended to use a freshly installed dust filter before starting the calibration procedure.

Page 20 of 42


Service

● Observe standard EN 50073 and/or the relevant national laws and regulations.

Daily

● Visual inspection to establish readiness for operation.

Commissioning

● Check zero- and sensitivity adjustment, page 17 to page 18.

● Check signal transmission to the controller and correct triggering of alarms.

At regular intervals, as specified by those responsible for the gas detection system (and which should not exceed an interval of six months):

●

●

Check zero- and sensitivity adjustment, page 17 to page 18.

Check signal transmission to the controller an make sure correct triggering of alarms (maintenance function SL – Set output to x mA, page 14).

Especially it must regularly be ensured that gas can freely penetrate the sinter disk and that there are neither corrosion nor deposits of dust, oil or aerosols.

Every six months

● Arrange for inspection by trained personnel

The inspection intervals in each individual case are influenced and if necessary shortened by technical safety considerations, engineering processes and the technical requirements of the equipment.

We recommend a DrägerService contract which also covers repairs.

If necessary

● Replace sensor, page 22.

Design and measuring principle

Design and measuring principle

The transmitter PEX 3000 consists of housing, an Ex-sensor and corresponding electronics.

The housing made of conductive plastic prevents electrostatic charge-up and is resistant to solvents.

The Ex-sensor is a transducer for measuring the partial pressure of flammable gases and vapours present in the atmosphere. They use the heat-of-reaction principle.

The monitored air is diffusing through the sintered metal disc into the Ex-sensor. This is where the mixture of flammable gases and vapours are catalytically combusted at a heated detector element (pellistor). The oxygen required for combustion is obtained from the monitored air. The detector element is additionally heated by the resultant heat of reaction. This heat in turn causes a change in the resistance of the detector element, which is proportional to the concentration of the flammable gas or vapour.

In addition to the catalytically active detector element, the Ex-sensor accommodates an inactive compensator element, which is likewise heated. Both elements are parts of a Wheatstone bridge. Environmental effects such as temperature, humidity or heat conductivity of the ambient air to be monitored, have identical effects on both the elements, whereby these effects on the measuring signal are almost completely compensated.

The sensor signal is amplified by the electronics, indicated on the display and converted into a 4 to 20 mA signal which is passed to the central controller.

Scope of this manual

This manual details the information needed to safely install and operate the

REGARD–1 single channel control unit manufactured by Draeger Safety UK Ltd.

This manual does not include information related to the associated transmitter or measuring head.

Intended use

The REGARD–1 control unit is designed for the continuous monitoring of flammable, toxic and/or other gases and the control of alarms, indicators or other equipment via digital outputs and alarm relays.

The control unit is designed for use in a control room environment. The atmosphere should be free of contaminants and pollutants, which are known to be harmful to electronic equipment.

The control unit is not designed or certified for use in areas where combustible or explosive gas mixtures are likely to occur.

No safety function is controlled by software. All safety functions are analogue.

Revision 4 manual includes

New measuring ranges of 0-8 and 0-20 added.

A1 and A2 dc output specification revised.

Fault relay terminals identified correctly.

Potentiometer for calibration re-named to FSD (VR1).

Relay terminal designation revised.

Introduction

Description

The control unit comprises of two main circuit boards, two options boards and a custom design enclosure.

Main circuit board

The main circuit board comprises of an AC/DC power supply, analogue circuitry and alarm relays/LED’s. Terminals along the bottom edge of the circuit board act as the interface between the field devices and the control unit. All optional circuit boards use a multi-pin plug/socket to connect to the main circuit board.

A small DIL switch allows for the configuration of the main circuit board to be customised. Conventional potentiometers are used for setting the calibration and alarm trip points. An inhibit jumper and test points are provided for use during commissioning and servicing.

Issue 4 03/09/04 4 of 29

Display circuit board

The display board comprises of a large LCD, LED’s, reset switch, piezo horn and associated electronics. The display board connects to the main circuit board via a short ribbon cable.

A small DIL switch allows the full-scale deflection of the display board to be set and the TWA computation to be activated (according to software version). The reset switch will reset/accept triggered alarms and reset the TWA value (if applicable).

Display board (4208581) with Rev 1.00 software does not allow a TWA alarm, just a rolling 8 hour calculation.

Display board (4208636) with Rev 2.00 software allows a TWA value to be computated and a TWA alarm to be set.

The LCD display shows different statuses. These are

- 2.5 Negative gas reading below zero and above under-range

10.7

True gas reading (typical)

The -OR- display is latching. The display can only be reset via the reset switch when the input is below full scale.

Pellistor input board (Optional)

The Pellistor board allows for the direct connection of a Pellistor measuring head. The

Pellistor board connects to SK2. Three potentiometers allow for the Pellistor drive current to be set and the zero/span points to be adjusted.

A small DIL switch allows for the sensitivity of the Pellistor input to be selected and the setting of two drive current ranges.

The maximum loop resistance that the Pellistor board can drive is 14 ohms (7 ohms per core) for the Draeger Pellistor at 270mA. The maximum cable lengths for 1.5mm

Options board (Optional)

The options board comprises of a TWA alarm relay, PC connection port and an isolated repeat 4..20mA output. The option board connects to SK6 and SK9. The field terminals associated with the TWA relay and repeat 4.20mA output are mounted on the main circuit board.

Enclosure

The enclosure is a custom design. The back box of the enclosure contains all of the electronic circuit boards, batteries (if fitted) and galvanic isolator (if fitted). A separate metal cable gland earth plate is available should metal cable glands be used.

The enclosure has three mounting points; one top centre and two at the bottom corners. All mounting points are non-intrusive to maintain the enclosure rating of

IP65.

The lid of the enclosure is fixed to the back box by six bolts. A special tool is required to loosen these fixing bolts

A plastic cradle is available to house a galvanic isolator (Stahl 9303) within the general enclosure. This cradle creates a separate enclosure within the general enclosure to separate the safe and hazardous terminals of the galvanic isolator.

Installation

Unpacking

There are no special precautions to be taken when unpacking the control unit from the carton. Care should be taken not to discard the Installation and Operating manual, which is packed in the carton.

All packing materials should be re-cycled if possible.

Mounting

The control unit should not be mounted in the following environments

Hazardous areas (without additional protection)

Surfaces with excess vibration

Environments containing aggressive and corrosive atmospheres

The control unit can be mounted directly onto the wall or any suitable robust surface.

The three-point mounting allows the control unit to be mounted on an irregular surface without the enclosure being distorted.

The mounting hole dimensions are detailed in Appendix A.

Issue 4 03/09/04 6 of 29

Cabling

The main cable access is via the bottom edge of the enclosure. There are five preformed M20 cable gland holes provided. A single pre-formed M20 cable gland is located on the top of the enclosure. It is recommended that the cable glands be fitted to the enclosure before the enclosure is mounted on the wall.

A separate gland earthing plate is available. This plate is fitted inside of the enclosure and earthed via a spade connector.

All field terminals, excluding the battery terminals are located along the bottom edge of the main circuit board. It is recommended that if stranded cable is used then these cables be fitted with a ferrule.

Termination details are shown in Appendix B

Mains supply

A three-core mains cable connects the control panel to a dedicated fused spur rated at

3 amps.

Transmitter

Irrespective of the type of analogue (4..20mA) transmitter connected to the control unit a 2 or 3 core (eg LiYCY) cable should be used. The screen of the cable should be connected to the cable gland.

For correct installation reference should be made to the appropriate transmitter

Operating Manual.

Appendix E shows typical transmitter connections.

Alarms

There are two types of alarm output; a switching 24vdc and voltfree relay contacts.

When connecting alarm devices to the switching 24vdc output it is recommended that

LiYCY type cable is used. When connecting alarm devices to the voltfree relay contacts there is no requirement to use LiYCY type cable.

Remote reset

The remote reset facility should be connected to a normally open switch. It is recommended that LiYCY type cable is used.

Issue 4 03/09/04 7 of 29

Note : The pre-formed cable gland holes should be drilled using a 20mm hole saw and not physically knocked out.

Location

The control panel should be mounted in a location, which is both accessible and visible. Where the ambient noise level is high it is recommended that a local alarm sounder is installed. Access to the panel will be necessary during an alarm condition and during servicing.

Internal batteries

Two internal batteries (type Yuasa NP1.2-12) can be installed in the control unit. The associated terminals are located along the top edge of the main circuit board.

If alternative batteries are used then care should be taken that Hydrogen gas is not generated during standard use. If Hydrogen gas is a concern then a M20 vent needs to be installed into the top cable entry hole.

‘OFF’ position the latched condition (silencing the klaxon) can be cleared during an alarm condition (gas still present).

Set latching/non-latching alarm relay mode

Alarm levels 1, 2, 3 and Fault can be set as either latching or non-latching. Each alarm level is independently set via a DIL switch on the main circuit board. Table 3 shows the relationship between the alarm condition and the DIL switch position.

Calibration

Zero adjustment

The control unit has no zero adjustment. The signal from the transmitter at 4mA (

±

32

µ

A) will automatically indicate zero gas. Should a gas value be indicated then the loop calibration must be adjusted at the transmitter.

Span adjustment

The control unit only needs a single point calibration. An input value of between 50% and 90% of the measuring range should be set as an input. Potentiometer FSD (VR1) should be adjusted to set the loop calibration.

The display can be used directly to set the calibration. Where the control unit has no display then a DVM can be connected across TP1 and TP2. Table 1 shows the relationship between a mV value on the DVM and an analogue value.

Issue 4 03/09/04 12 of 29

Pellistor input (Optional)

The Pellistor board is connected to SK2 on the main circuit board once jumpers A to

E are removed (see Appendix D). Two additional PCB pillars support the top edge of the circuit board. A single DIL switch allows the drive current ranges and Pellistor sensitivities to be set.

Setting Pellistor drive current

There are two drive current ranges as detailed in table 3. According to the type of

Pellistor connected SW1 needs to be either ‘ON’ or ‘OFF’.

Connect an ammeter between terminal 9 of the main circuit board and the detector of the Pellistor. Adjust VR2 to set the drive current. Allow the current to stabilise before removing the DVM.

Warning – ensure that the control panel is switched off during the connection and disconnection of the ammeter.

Pellistor zero calibration

Connect a DVM between test TP1 and TP2. Adjust VR1 on the pellistor board until the DVM reads 800mV

±

20mV. If a display is fitted to the control unit then the display will display zero.

Pellistor span calibration (control unit with display)

The calibration is performed by using the coarse adjust potentiometer (VR3) on the

Pellistor circuit board and FSD (VR1) on the main circuit board.

Issue 4 03/09/04 13 of 29

Potentiometer FSD (VR1) on the main circuit board should be turned fully anticlockwise. Apply a known calibration gas to the Pellistor and allow the reading to stabilise for two minutes. Adjust VR3 on the Pellistor circuit board until the display shows the correct gas value.

If additional gain is required then FSD (VR1) on the main circuit board can be used.

If additional gain is required then FSD (VR1) on the main circuit board can be used.

Options board

The options board is connected to SK6 and SK9 on the main circuit board. A single

PCB pillar supports the top edge of the circuit board. The options board provides a relay output for the TWA function, an RS232 output for the data/logger, and an isolated 4..20mA current loop repeater.

The relay and its connections on the main board are distanced to permit connection to either mains or 24Vdc potentials.

The RS232 conversion is done using the Maxim MAX232 chip. Physical RS232 output is provided by an RJ44SV connector on the ‘options board’ itself.

The galvanically isolated 4..20mA loop repeater uses an isolated 1W dc-dc converter to power the ‘isolated-side’ circuits and provide the source current. Current may be adjusted using VR1 on the options board.

General specification

Remote reset

Two terminals are provided for a remote reset switch. Under normal operation these terminals are open circuit and require a momentary (0.5 seconds) closing to operate.

The remote reset switch also resets the TWA computation if the switch is held close for approximately 10 seconds.

Repeat 4..20mA

See Options board

Issue 4 03/09/04 14 of 29

24 volt DC output

Two terminals are provided to power external devices including a galvanic isolator.

The maximum current available is 100mA (see technical specification for detail). A polyfuse protects the output against overload or short circuit.

Digital outputs

An independent digital output is provided for both alarms 1 and 2. These outputs provide switching 24vdc at 100mA. These outputs are reset either during an alarm condition or after an alarm condition by pressing the reset switch. If the reset switch is not pressed then the output is latching.

Relay outputs

Relay outputs are provided for

Fault

Inhibit

TWA alarm (see Options board)

All alarm relays offer normally open, common and normally closed contacts. The fault relay is normally energised. All other relays are ‘energise on alarm’.

Each relay is distanced to permit connection to either mains or 24vdc potentials.

AC output

Three terminals are provided to power external devices. The output voltage is equal to the input voltage. A single fuse (F5) protects the ‘L’ output. The ‘L’ output fuse is rated at 500mA.

Inhibit jumpers

A single two pole jumper is provided to inhibit the alarms during servicing. A short circuit across the jumpers initiates the inhibit function.

Note – any alarm relay energised will be automatically de-energised if the inhibit jumper is used.

Issue 4 03/09/04 15 of 29

Servicing

The recommended service interval for the control unit is twelve months, however this interval may be shortened depending upon the service interval of the associated transmitter.

If batteries are fitted to the control unit then these batteries should be maintained inaccordance with the instructions of the battery manufacturer.

To service the control panel the commissioning procedure should be repeated.

When fluid flows through the unit it causes the magnetic piston to move up at the calibration point. This displacement is caused by the pressure differential from the fluid flowing through the unit. The magnetic piston actuates a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the fluid path.

Decreasing the flow below the calibration point causes the reed switch to de-actuate.

• Actuation points for air at 68˚ F and 14.7 PSIA with increasing flow.

• Deactuation (decreasing flow) averages ± 10% less than actuation (increasing flow).

• Flow setting accuracy 10% of calibration points shown.

• Repeatability ± 1%.

• Unit will pass greater flows.

Depending on the chemical nature of the gas being filtered, other plastic filter housings should be considered e.g. polypropylene, (pages 24-25) or PVDF

(page 26). The convenience of complete disposability and low initial cost may make Headline’s DIF’s (page 6-7) a more suitable product option.

Housings accepting elements 12-32 & 12-57 are sold singly or in packs of 100.

MOUNTING INSTRUCTIONS

This operator interface is designed for through-panel mounting. A panel cutout diagram and a template are provided. Care should be taken to remove any loose material from the mounting cut-out to prevent that material from falling into the operator interface during installation. A gasket is provided to enable sealing to NEMA 4X/IP66 specification. Install the ten kep nuts provided and tighten evenly for uniform gasket compression.

Note: Tightening the kep nuts beyond a maximum of 17 inch-pounds (1.92 Nm) may cause damage to the front panel.

The chassis ground is not connected to signal common of the unit.

Maintaining isolation between earth ground and signal common is not required to operate your unit. But, other equipment connected to this unit may require isolation between signal common and earth ground. To maintain isolation between signal common and earth ground care must be taken when connections are made to the unit.

For example, a power supply with isolation between its signal common and earth ground must be used. Also, plugging in a USB cable may connect signal common and earth ground.

USB’s shield may be connected to earth ground at the host. USB’s shield in turn may also be connected to signal common.

All tolerances ±0.010" (±0.25 mm).

ALL NONINCENDIVE CIRCUITS MUST BE WIRED USING

DIVISION 2 WIRING METHODS AS SPECIFIED IN ARTICLE 501-

4 (b), 502-4 (b), AND 503-3 (b) OF THE NATIONAL ELECTRICAL

CODE, NFPA 70 FOR INSTALLATION WITHIN THE UNITED

STATES, OR AS SPECIFIED IN SECTION 19-152 OF CANADIAN

ELECTRICAL CODE FOR INSTALLATION IN CANADA.

CONNECTING TO EARTH GROUND

The protective conductor terminal is bonded to conductive parts of the equipment for safety purposes and must be connected to an external protective earthing system.

POWER SUPPLY REQUIREMENTS

The G306A requires a 24 VDC power supply. Your unit may draw considerably less than the maximum rated power depending upon the options being used. As additional features are used your unit will draw increasing amounts of power. Items that could cause increases in current are additional communications, optional communications card, CompactFlash card, and other features programmed through Crimson.

In any case, it is very important that the power supply is mounted correctly if the unit is to operate reliably. Please take care to observe the following points:

– The power supply must be mounted close to the unit, with usually not more than 6 feet (1.8 m) of cable between the supply and the operator interface. Ideally, the shortest length possible should be used.

– The wire used to connect the operator interface’s power supply should be at least 22-gage wire. If a longer cable run is used, a heavier gage wire should be used. The routing of the cable should be kept away from large contactors, inverters, and other devices which may generate significant electrical noise.

– A power supply with a Class 2 or SELV rating is to be used. A Class 2 or SELV power supply provides isolation to accessible circuits from hazardous voltage levels generated by a mains power supply due to single faults. SELV is an acronym for “safety extra-low voltage.” Safety extra-low voltage circuits shall exhibit voltages safe to touch both under normal operating conditions and after a single fault, such as a breakdown of a layer of basic insulation or after the failure of a single component has occurred.

Each G306A has a chassis ground terminal on the back of the unit. Your unit should be connected to earth ground (protective earth).

CONFIGURING A G306A

The G306A is configured using Crimson ® software. Crimson is available as a free download from Red Lion’s website, or it can be purchased on CD. Updates to Crimson for new features and drivers are posted on the website as they become available. By configuring the G306A using the latest version of Crimson, you are assured that your unit has the most up to date feature set. Crimson ® software can configure the G306A through the RS232 PGM port, USB port, or CompactFlash.

The USB port is connected using a standard USB cable with a Type B connector. The driver needed to use the USB port will be installed with Crimson.

The RS232 PGM port uses a programming cable made by Red Lion to connect to the DB9 COM port of your computer. If you choose to make your own cable, use the “G306A Port Pin Out Diagram” for wiring information.

The CompactFlash can be used to program a G3 by placing a configuration file and firmware on the CompactFlash card. The card is then inserted into the target

G3 and powered. Refer to the Crimson literature for more information on the proper names and locations of the files.

USB, DATA TRANSFERS FROM THE

COMPACTFLASH CARD

CABLES AND DRIVERS

Red Lion has a wide range of cables and drivers for use with many different communication types. A list of these drivers and cables along with pin outs is available from Red Lion’s website. New cables and drivers are added on a regular basis. If making your own cable, refer to the “G306A Port Pin Outs” for wiring information.

ETHERNET COMMUNICATIONS

Ethernet communications can be established at either 10 BASE-T or 100

BASE-TX. The G306A unit’s RJ45 jack is wired as a NIC (Network Interface

Card). For example, when wiring to a hub or switch use a straight-through cable, but when connecting to another NIC use a crossover cable.

The Ethernet connector contains two LEDs. A yellow LED in the upper right, and a bi-color green/amber LED in the upper left. The LEDs represent the following statuses:

WARNING - DO NOT CONNECT OR DISCONNECT CABLES

WHILE POWER IS APPLIED UNLESS AREA IS KNOWN TO BE

NON-HAZARDOUS. USB PORT IS FOR SYSTEM SET-UP AND

DIAGNOSTICS AND IS NOT INTENDED FOR PERMANENT

CONNECTION.

In order to transfer data from the CompactFlash card via the USB port, a driver must be installed on your computer. This driver is installed with Crimson and is located in the folder C:\Program Files\Red Lion Controls\Crimson 2.0\Device\ after

Crimson is installed. This may have already been accomplished if your G306A was configured using the USB port.

Once the driver is installed, connect the G306A to your PC with a USB cable, and follow “Mounting the CompactFlash” instructions in the Crimson 2 user manual.

On the rear of each unit is a unique 12-digit MAC address and a block for marking the unit with an IP address. Refer to the Crimson manual and Red

Lion’s website for additional information on Ethernet communications.

RS232 PORTS

The G306A has two RS232 ports. There is the PGM port and the COMMS port. Although only one of these ports can be used for programming, both ports can be used for communications with a PLC.

The RS232 ports can be used for either master or slave protocols with any

G306A configuration.

Examples of RS232 communications could involve another Red Lion product or a PC. By using a cable with RJ12 ends on it, and a twist in the cable, RS232 communications with another G3 product or the Modular Controller can be established. Red Lion part numbers for cables with a twist in them are

TOUCHSCREEN

This operator interface utilizes a resistive analog touchscreen for user input.

The unit will only produce an audible tone (beep) when a touch on an active touchscreen cell is sensed. The touchscreen is fully functional as soon as the operator interface is initialized, and can be operated with gloved hands.

KEYPAD

The G306A keypad consists of five keys that can be used for on-screen menus.

DISPLAY

This operator interface uses a liquid crystal display (LCD) for displaying text and graphics. The display utilizes a cold cathode fluorescent tube (CCFL) for lighting the display. The CCFL tubes can be dimmed for low light conditions.

These CCFL tubes have a limited lifetime. Backlight lifetime is based upon the amount of time the display is turned on at full intensity. Turning the backlight off when the display is not in use can extend the lifetime of your backlight. This can be accomplished through the Crimson ® software when configuring your unit.

TROUBLESHOOTING YOUR G306A

If for any reason you have trouble operating, connecting, or simply have questions concerning your new G306A, contact Red Lion’s technical support.

BATTERY & TIME KEEPING

WARNING - EXPLOSION HAZARD - THE AREA MUST BE

KNOWN TO BE NON-HAZARDOUS BEFORE SERVICING/

REPLACING THE UNIT AND BEFORE INSTALLING OR

REMOVING I/O WIRING AND BATTERY.

WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT

EQUIPMENT UNLESS POWER HAS BEEN DISCONNECTED

AND THE AREA IS KNOWN TO BE NON-HAZARDOUS.

A battery is used to keep time when the unit is without power. Typical accuracy of the G306A time keeping is less than one minute per month drift. The battery of a G306A unit does not affect the unit’s memory, all configurations and data is stored in non-volatile memory.

CAUTION: RISK OF ELECTRIC SHOCK

The inverter board, attached to the mounting plate, supplies the high voltage to operate the backlight. Touching the inverter board may result in injury to personnel.

CAUTION : The circuit board contains static sensitive components. Before handling the operator interface without the rear cover attached, discharge static charges from your body by touching a grounded bare metal object. Ideally, handle the operator interface at a static controlled clean workstation. Also, do not touch the surface areas of the circuit board. Dirt, oil, or other contaminants may adversely affect circuit operation.

To change the battery of a G306A, remove power, cabling, and then the rear cover of the unit. To remove the cover, remove the four screws designated by the arrows on the rear of the unit. Then, by lifting the top side, hinge the cover, thus providing clearance for the connectors on the bottom side of the PCB as shown in the illustration below. Install in the reverse manner.

Remove the old battery* from the holder and replace with the new battery.

Replace the rear cover, cables, and re-apply power. Using Crimson or the unit’s keypad, enter the correct time and date.

* Please note that the old battery must be disposed of in a manner that complies with your local waste regulations. Also, the battery must not be disposed of in fire, or in a manner whereby it may be damaged and its contents come into contact with human skin.

The battery used by the G306A is a lithium type CR2025.

TOWN AND COUNTRY PLANNING ACT 1990

Appeals to the Secretary of State

∗

If you are aggrieved by the decision of your Local Planning Authority to refuse permission for the proposed development or to grant it subject to conditions, then you can appeal to the

Secretary of State for the Environment under Section 78 of the Town and Country Planning

Act 1990.

∗

If you want to appeal then you must do so within SIX months of the date of this notice, using a form, which is available from the Planning Inspectorate, (a copy of which must be sent to

Newham Council) or complete an application online.

The Planning Inspectorate, Temple Quay House, 2 The Square, Temple Quay, Bristol, BS1

6PN (e-mail: [email protected]

) or (Tel: 0117 372 8000).

To make an appeal online, please use www.planningportal.gov.uk/pcs . The Inspectorate will publish details of your appeal on the internet. This may include copies of documentation from the original planning application and relevant supporting documents supplied to the local authority, and or information, including personal information belonging to you that you are happy will be made available in this way. If you supply personal information belonging to a third party please ensure you have their permission to do so. More detailed information about data protection and privacy matters is available on the Planning Portal.

∗

The Secretary of State can allow a longer period for giving notice of an appeal, but he will not normally be prepared to use this power unless there are special circumstances, which excuse the delay in giving notice of appeal.

∗

The Secretary of State need not consider an appeal if it seems to him that the Local Planning

Authority could not have granted it without the conditions it imposed, having regard to the statutory requirements, to the provisions of the development order and to any directions given under the order.

∗

In practice, the Secretary of State does not refuse to consider appeals solely because the

Local Planning Authority based its decision on a direction given by him.

Purchase Notice

∗

If either the Local Planning Authority or the Office of the Deputy Prime Minister refuses permission to develop land or grants it subject to conditions, the owner may claim that he can neither put the land to a reasonably beneficial use in its existing state nor can he render the land capable of a reasonably beneficial use by carrying out any development which has been or would be permitted.

∗

In these circumstances, the owner may serve a purchase notice on the Council in whose area the land is situated. This notice will require the Council to purchase his interest in the land in accordance with Part VI of the Town and Country Planning Act 1990.
