Important

Be sure to read and understand the entire instruction manual before installing or operating the gas detection system. This product is intended to provide early warning of the presence of a toxic or explosive gas mixture, or of oxygen depletion. Proper device installation, operation, and maintenance are required to ensure safe and effective operation. If this equipment is used in a manner not specified in this manual, safety protection may be impaired.

that are able to monitor a linear 4-20 mA dc signal. All alarm functions are provided by the monitoring device.

The GT3000 is designed and approved as a stand alone unit for use in hazardous locations. It is suitable for outdoor applications that require IP66 rating and uses a hydrophobic filter that is easily replaced without opening the device or use of tools. The GT3000 is furnished as either explosion-proof or intrinsically safe.

The GT3000 supports local one-person calibration with the use of a magnet and on-board LED.

Description

The GT3000 Electrochemical Gas Detector is an intelligent stand-alone industrial gas detector, designed to provide continuous monitoring of the atmosphere for hazardous gas leaks or oxygen depletion. It is fully performance tested and approved by Factory Mutual.

Refer to Appendix F for individual gas specifications.

GTS SENSOR MODUlE

The GTS’s electrochemical sensor cell uses capillary diffusion barrier technology for monitoring gas concentrations in ambient air.

The GT3000 Gas Detector consists of a replaceable sensor module (Model GTS) connected to a transmitter module (Model GTX). A single transmitter is compatible with all GTS sensor modules. A variety of electrochemical sensor models are available in various concentration ranges.

The GT3000 is a 2-wire device that generates a 4-20 mA output signal with HART communication that is proportional to the concentration of the target gas.

live Maintenance

The hot swappable GTS sensor module is intrinsically safe and allows live maintenance while under power, without de-classifying the hazardous area. When the sensor is removed, the transmitter generates a fault output. If a new sensor of the same type and range is installed, the fault self-clears. However, if the type or range of the new sensor module does not match the old, the transmitter generates a fault until a successful calibration or acceptance of the new sensor type is completed. For additional information regarding Live

Maintenance, refer to “Sensor Module Replacement” in the Maintenance section of this manual.

The GT3000 is compatible with FlexVu

Automatic Sensor Module Recognition

The transmitter provides automatic gas sensor recognition, allowing the operator to access the following information via HART, or a UD10 or UD20

Universal display:

• Date of manufacture of the sensor module

• Sensor module serial number

• Gas type

• Measurement range

HISTORY/EvENT lOGS

Both the transmitter and sensor are able to store 256 history logs, which are saved in non-volatile memory and retained through power cycles. A UD10/UD20

Universal Display Unit, a HART communication device, or AMS software is required to view the history logs.

The sensor module is factory programmed for the gas type and measurement range. When the sensor module powers up, the transmitter reads and acknowledges the gas type and measurement range.

GTX TRANSMITTER

The transmitter output is a linear 4-20 mA dc signal with HART communication that directly corresponds to

0-100% full scale.

A 3.8 mA output indicates sensor calibration in progress

(17.3 mA for O

2

sensor). The GT3000 comes with one of two pre-programmed fault output levels: 2.45 mA or

3.5 mA.

Priority of output signals from highest to lowest is:

Sensor logging Capability

The sensor module logs the following operating parameters in non-volatile memory:

• Running Hours

- The sensor module maintains the total operating hours, and cannot be reset.

• Min/Max Temperature

- The sensor module maintains the minimum and maximum temperatures with a date and time stamp.

• Calibration

- The sensor module logs the calibration history with a date and time stamp, along with the success or cause of failure codes. See Table 1. The zero and span values (AD converter values recorded at the time of calibration) are also saved. This allows the logs to follow the sensor module when it is calibrated separately from the transmitter. (Calibration data is available via a UD10/UD20, a HART communication device, or AMS software.)

The sensor module gets the current time and date from the transmitter and provides calibration log information to the transmitter. See Figure 1.

Transmitter Wiring

The GTX transmitter is a two-wire loop powered device that uses a three-wire cable (power, signal, and earth ground) for connecting to a controller or monitoring device. The use of shielded cable is required.

REAl TIME ClOCk (RTC)

The GTX transmitter has a real time clock with battery back-up, that is used for time stamping the event logs.

The time and date are set and read using a UD10/

UD20 Universal Display Unit, a HART communication device, or AMS software. The time stamp on the logs will not be correct if the RTC in the transmitter is not set correctly.

The gas detector can be installed either in a stand-alone configuration as a loop powered device, or it can be connected to a UD10/UD20 Universal Display Unit.

housing.

NoTe

The gas detector housing must be electrically connected to earth ground. A dedicated earth ground wire is provided on the transmitter for connection to earth ground or to a grounded

The most effective number and placement of detectors varies depending on the conditions on site. The individual designing the installation must often rely on experience and common sense to determine the detector quantity and best locations to adequately protect the area. Note that it is typically advantageous to locate detectors where they are accessible for maintenance. Locations near excessive heat or vibration sources should be avoided if possible.

Final suitability of possible gas detector locations should be verified by a site survey. If any questions arise regarding installation, please contact the factory.

The detector must always be installed per local installation code.

Before installing the gas detector, define the following application details:

DEvICE MOUNTING ORIENTATION

The gas detector must be mounted in a vertical position only, with the sensor pointing down (See Figure 5).

IDENTIFICATION OF vApOR(S) TO bE DETECTED

It is necessary to always identify the vapor(s) of interest at the job site. In addition, the fire hazard properties of the vapor, such as vapor density, flashpoint, and vapor pressure should be identified and used to assist in selecting the optimum detector mounting location within the area.

Important

The sensor should be oriented with the LeDs facing forward so they are easily visible to personnel within the area. To ensure correct orientation (the LeDs are not visible when power is off), position the GND lug on the left hand side and the calibration notch to the front. Note that the

LeDs are located directly above the calibration notch.

IDENTIFICATION OF DETECTOR MOUNTING lOCATIONS

Identification of the most likely leak sources and leak accumulation areas is typically the first step in identifying the best detector mounting locations. In addition, identification of air current/wind patterns within the protected area is useful in predicting gas leak dispersion behavior. This information should be used to identify optimum sensor installation points.

If the vapor of interest is lighter than air, place the sensor above the potential gas leak. Place the sensor close to the floor for gases that are heavier than air. Note that air currents may cause a gas that is slightly heavier than air to rise under some conditions. Heated gases may also exhibit the same phenomenon.

DETECTOR INSTAllATION

3/4" NpT Models

3/4" NPT models have Tapered Threads and no Lock

Nut. Install the sensor as follows:

1. Screw the detector into the appropriate entry on the termination box. Ensure a minimum of 5 fully engaged threads. Use of teflon tape on NPT threads is recommended to prevent thread damage.

2. When the detector gets tight, note the position of the

LEDs, GND lug and calibration notch and adjust the detector as required so that the LEDs will be easily visible.

SENSOR TERMINATION bOX

A Det-Tronics sensor termination box (Model STB) is required for installing the sensor in a stand alone configuration, or for installing the GT3000 remotely from the UD10/UD20 Universal Display Unit.

When installing the GT3000 remotely from a UD10/

UD20, two-conductor shielded cable is required to prevent possible nuisance EMI/RFI. The maximum cable length between the GT3000 and the UD10/UD20 is 2000 ft.

WirinG

M25 Models

M25 models have Straight Threads and a Lock Nut.

Install the detector as follows:

1. Screw the detector lock nut as far back as it will go, then screw the detector into the appropriate entry on the termination box. Ensure a minimum of 7 fully engaged threads.

2. With the detector in the desired position (LEDs visible as shown in Figure 5), tighten the lock nut against the termination box to hold the detector securely in place.

3. Tighten the set screws (minimum of two) to prevent movement of the lock nut. See Figure 6.

pOWER SUpplY REqUIREMENTS

Calculate the total gas detection system power consumption rate in watts from cold start-up. Select a power supply with adequate capability for the calculated load. Ensure that the selected power supply provides sufficient regulated and filtered output power for the entire system. If a back-up power system is required, a float-type battery charging system is recommended. If an existing source of power is being utilized, verify that system requirements are met.

NoTe

The power supply must also meet the noise requirements for HART systems.

WIRING CAblE REqUIREMENTS

Always use proper cabling type and diameter for input power as well as output signal wiring. 22 to 14 AWG shielded stranded copper wire is recommended.

Always install a properly sized, master power fuse or breaker on the system power circuit.

Set Screws

Figure 6—Location of Lock Nut and Set Screws

(Metric Models Only)

NoTe

The use of shielded cable in conduit or shielded armored cable is highly recommended. In applications where the wiring is installed in conduit, dedicated conduit is recommended.

Avoid low frequency, high voltage, and non-signaling conductors to prevent nuisance eMI problems.

CaUtIon

The use of proper conduit installation techniques, breathers, glands, and seals is required to prevent water ingress and/or maintain the explosion-proof rating.

INTRINSIC SAFETY bARRIERS

When the GT3000 is used in an intrinsically safe installation, care must be taken when selecting an I.S. barrier to ensure proper function of the device. The

GT3000 has been tested with the types of barriers listed in Tables 3 and 4.

GUIDElINES FOR INTRINSIC SAFETY WIRING

Intrinsically safe systems must be installed in accordance with the approved control drawings for the field equipment and the intrinsic safety barriers.

Capacitance and inductance of interconnecting wiring must always be included in wiring calculations.

Table 3 lists zener barriers. The third column gives the range of input voltage to the barrier. The upper limit is set by the barrier. The lower limit is limited by voltage drops in the 4-20 mA loop with a maximum of 10 Ohms of resistance in each leg of the loop.

Table 4 lists isolating barriers that provide a wider range of input power supply voltages and are less dependent on voltage drops in the loop. Input voltage to the barrier is specified by the barrier manufacturer.

Shielded twisted pair cables with at least 18 AWG conductors are recommended to ensure circuit performance.

The intrinsically safe conductors must be separated from all other wiring by placing them in separate conduits or raceways, or by an airspace of at least 2 inches (50 mm). When located within an enclosure, the conductors can be separated by a grounded metal or insulated partition. Wires must be tied down to prevent loosening and/or shorting.

For additional information regarding proper IS installation, refer to the Control Drawings in Appendix

H of this manual.

Intrinsically safe wiring must be identified. Raceways, cable trays, open wiring, and terminal boxes must be labeled as Intrinsically Safe. Intrinsically safe wiring may be light blue in color when no other conductors colored light blue are used.

Wiring enclosures should be located as close as possible to the hazardous area to minimize cable runs and reduce total capacitance of the wiring.

A high quality intrinsic safety ground is required. Some general rules for grounding intrinsically safe systems are:

• The maximum impedance of the grounding conductor between the barrier ground terminal and the main ground point must be less than 1 ohm.

• The grounding conductor must be a minimum of 12

AWG.

• Redundant grounding conductors are recommended to facilitate testing of the ground connection.

• The grounding conductor should be insulated and protected from the possibility of mechanical damage.

calibration

GT3000 CAlIbRATION

The GT3000 supports one person calibration, which can be initiated locally using a calibration magnet, or remotely with a command from the HART interface.

The calibration process is automatic, with the exception of gas delivery. LEDs on the transmitter guide the operator when to apply and remove the calibration gas

See Table 5.

NoTe

The HART interface allows the operator to adjust the calibration gas concentration within the range of 30 to 90% full scale. The default value for all gas sensors except oxygen is 50% full scale. oxygen sensors use a default value of 20.9%.

The calibration process proceeds automatically after initiation. Onboard LEDs signal the operator when to apply the calibration gas and inform of the progress.

The calibration can be aborted by activating the magnetic switch or with a command from the HART communication device in lieu of applying the calibration gas.

If the calibration process takes longer than 10 minutes, the detector will time-out and signal a calibration fault.

If the calibration sequence is aborted or not completed successfully, the detector reverts back to the previous calibration values and signals a calibration fault. The calibration fault can be cleared by activating the magnetic switch for one second or by performing a successful calibration.

All GT3000 gas detectors require a two-point calibration — zero and span. The calibration process can be initiated using the magnetic switch or through a

HART interface, such as the UD10/UD20. All sensors, including oxygen, should be in clean air (20.9% oxygen) when the calibration sequence is initiated.

The calibration process can fail for the following causes:

• Zero is out of range

• Span is out of range

• Time-Out.

The time and date of calibration events are logged in non-volatile memory along with the calibration outcome.

The Sensor Module stores calibration data in non-volatile memory to allow the sensor to be calibrated off-site and installed in the field without the need for re-calibration.

CAlIbRATION pROCEDURE

NoTe

When attaching or removing the calibration cup, push or pull the cup with a slight

clockwise twist.

Turning counterclockwise can cause the filter assembly on the GT3000 to loosen. If the filter assembly is inadvertently loosened, tighten it by hand (no tools required).

NoTe

The calibration procedure must be completed within a ten minute period. If the calibration is not completed, a calibration fault will be generated and the transmitter will continue to use the previous calibration data.

Toxic and Hydrogen Sensors

1. Clean air must be present at the GT3000 sensor module prior to initiating calibration. The use of bottled air is recommended.

NoTe

To ensure reliable detection performance, calibration should be performed at regularly scheduled intervals. Various factors affect the time interval between periodic calibrations

(typically 30, 60, or 90 day intervals, depending on the ambient conditions).

Calibration of ammonia sensor is recommended any time the sensor has been exposed to 90 ppm ammonia.

NoTe

2. Initiate calibration by momentarily holding the calibration magnet against the designated location on the sensor module (see Figure 13) until the green LED turns off and the yellow LED turns on steady (approximately one second). Remove the magnet when the green LED turns off. The detector immediately begins taking zero readings.

Calibration can also be initiated via HART interface

(see Appendix G) or the UD10 (see manual number

95-8618).

Oxygen Sensor

1. Using the magnet, activate the magnetic calibration switch on the GT3000. The green LED turns off and the yellow LED turns on steady.

3. When the zero calibration is complete, the yellow

LED changes from steady to blinking. Apply the calibration gas to the sensor.

2. The device automatically performs the zero calibration.

3. When the yellow LED on the GT3000 flashes, the device automatically performs the span calculation.

If using bottled 20.9% oxygen, apply immediately.

4. When the yellow LED turns off, remove the calibration gas. The gas level at the sensor gradually returns to zero. The green LED turns on steady to indicate that the device has returned to normal operation, using the new calibration data.

4. After successful calibration, the yellow LED turns off and the green LED turns on steady to indicate that the device has returned to normal operation, using the new calibration data. Remove calibration gas (if used).

maintenance

NoTe

Refer to the GT3000 Safety Manual (number

95-8685) for specific requirements and recommendations applicable to the proper installation, operation, and maintenance of all

SIL-Certified GT3000 gas detectors.

ROUTINE INSpECTION

The gas inlet to the sensor should be inspected periodically, or during scheduled maintenance, to ensure that external obstructions such as plastic bags, litter, heavy oil and tar, paint, mud, snow, or other materials do not block the flow of gas to the sensor, thereby impairing the performance of the device.

To replace a dirty or damaged filter, simply grasp the filter assembly and twist counterclockwise to remove.

Screw the new filter in place on the sensor module. Do not overtighten. See Figure 14.

To ensure reliable protection, it is important to check and calibrate the detection system on a regularly scheduled basis. The frequency of these checks is determined by the requirements of the particular installation – typically

30, 60, or 90 day intervals, depending on the ambient conditions.

SENSOR MODUlE REplACEMENT

(live Maintenance)

The hot swappable, intrinsically safe sensor module can be replaced in the field without removing power or de-classifying the hazardous area.

To replace the sensor module, locate the three captive screws on the front of the module as shown in Figure

15. Loosen these screws and remove the old sensor module. Install the new sensor module onto the transmitter, and tighten the screws. To ensure proper moisture ingress protection and grounding of the plastic nosepiece, tighten the screws to 70-100 oz-in (0.5-0.7

N-m).

Important

Always exercise caution when working in combustible gas areas. Follow replacement instructions explicitly.

NoTe

Removing the sensor module with power applied will result in a fault condition until a new sensor module of the same type is installed. When replacing an oxygen sensor, this action will result in an alarm condition as the decreasing 4-20 mA signal passes through the alarm range. Inhibit response devices to prevent unwanted actuation.

NoTe oxygen (o

2

) electrochemical sensors contain lead (Pb). observe all local waste management requirements when disposing of exhausted o

2 electrochemical sensors.

NoTe electrochemical sensors are highly sensitive to antiseptic wipes and/or cleaning products that contain alcohol and antibacterial/antiviral agents.

Antiseptic products should be removed from areas where sensors are stored, handled, or used. If antiseptic products are being used on workers' hands, sufficient time should be allowed for the alcohol to evaporate before handling sensors.

DeVice repair anD retUrn

Prior to returning devices, contact the nearest local

Detector Electronics office so that a Return Material

Identification (RMI) number can be assigned. A

written statement describing the malfunction must accompany the returned device or component to assist and expedite finding the root cause of the failure

.

Pack the unit properly. Always use sufficient packing material. Where applicable, use an antistatic bag as protection from electrostatic discharge.

NoTe

Inadequate packaging that ultimately causes damage to the returned device during shipment will result in a service charge to repair the damage incurred during shipment.

Return all equipment transportation prepaid to the factory in Minneapolis.

NoTe

It is highly recommended that a complete spare be kept on hand for field replacement to ensure continuous protection.
