Introduction

Product overview

Emerson has designed the GDU-01-TT Ultrasonic Test Transmitter to electrically replace the airborne ultrasound generated from a pressurized gas leak using a piezoelectric disc. You can use the GDU-01-TT to activate alarm conditions with any ultrasonic gas leak detector. When gas moves from a high-pressure area to a low-pressure area, it generates airborne ultrasound. The ultrasonic sound level depends on three main factors:

• Pressure drop across leak
• Size of leak (area)
• Specific gas properties (molecular weight and specific gas ratio)

The GDU-01-TT is constructed from 316 stainless steel mounting hardware and a semi-crystalline polyphenylene sulfide (PPS) enclosure. The transmitter is battery-operated and is intended to be activated within close proximity of an ultrasonic detector. When activated, the transmitter helps to confirm that the ultrasonic detector is operating correctly.
The transmitter’s effective range, due to the nature of the electronically produced ultrasound, is 8m. The range may be reduced based on the level of
background ultrasound being generated in close proximity to the ultrasonic detector that the GDU-01-TT is activating.

Product recycling/disposal

Consider recycling equipment and packaging. Dispose of the product and packaging in accordance with local and national legislations and regulations.

Safety guidelines

WARNING
Use in hazardous areas
The GDU-01-TT is not hazardous area certified.
Only use the GDU-01-TT in accordance with site specific safety guidelines for non-certified equipment.

CAUTION
Only use the GDU-01-TT with Emerson approved accessories and charging equipment.

Important
All liability for the correct function of the GDU-01-TT is irrevocably transferred to the owner/operator if the GDU-01-TT is altered incorrectly by personnel not authorized by Emerson or if the GDU-01-TT is used in nonconformance to its intended use.

Unpack and inspect

Procedure

1. Carefully remove all components from the packaging.
2. Verify the components against the enclosed packing list.
3. Inspect all components for obvious damage, such as broken or loose parts.
4. If any components are missing or damaged, contact your local Emerson representative or the factory immediately.

Store the transmitter in a covered, dry, clean, and safe environment. Ensure that the storage temperature is between -20 °C and 75 °C and that relative
humidity does not exceed 95 percent non-condensing. Periodically inspect the stored box to ensure no tampering or deterioration has occurred.

Operation

The key for correct operation of the GDU-01-TT Ultrasonic Test Transmitter is in the relationship between the ultrasonic transmitter and ultrasonic detector.
Due to the nature of electronically emitted ultrasonic waves for optimal performance, it is very important to have the transmitter aligned perpendicular (±2.5 °) to the decibel sensing face. The closer the GDU-01-TT is to the detector, the higher the detector’s decibel output.
The GDU-01-TT has no adjustable controls and is set up to produce approximately 106 dB at 1 meter in single operation mode.

CAUTION
The test transmitter is not intended to output a precise sound pressure level (SPL).
Do not attempt to calibrate ultrasound detectors using this equipment.

Operate

Prerequisites
Ensure that the GDU-01-TT is fully charged before use. Refer to Charge the battery for charging instructions.

Procedure

1. Turn the rotary switch to the On position. See Figure 4-3.
   During normal operation, the On/Off indicator will be illuminated and the battery low indicator will be off.
   Note
   If the Battery Low indicator is illuminated, Emerson recommends charging the GDU-01-TT before use.

2. Remove the transmitter cap located on the ultrasonic emitter (see Figure 4-2) and aim the GDU-01-TT at the ultrasonic detector.
   To achieve best results see Verifying alarm settings through Activating a time delayed alarm.

3. Press and hold the Activation button to transmit an ultrasound emission.
   During normal operation, the activation indicator will illuminate to show ultrasound emission. If the activation indicator is off at any time while the button is pressed, the results are invalid.

Postrequisites
Once you have finished testing the detector, Emerson recommends replacing the transmitter cap and turning off the GDU-01-TT, turning the rotary switch to the Off position (Figure 4-3), and ensuring that the On/Off indicator light is off. This helps to prolong battery life.

Verifying alarm settings

Determine the ultrasonic detector alarm settings before using the GDU-01TT for operational verification.
The operator will need to determine the distance, or range, between the GDU-01-TT and the ultrasonic detector based on the ultrasonic detector’s alarm level. In general, the higher the alarm level setting, the shorter you need to make the distance between the detector and the GDU-01-TT.

Activating a time delayed alarm

For alarm verification, determine the detector alarm delay before using the GDU-01-TT.
Activate the transmitter using the Activation button for a time longer than the delay and ensure that the activation indicator is illuminated for the specified time. Emerson recommends turning off the alarm delay during the test. Ensure the time delay is reinstated after testing to prevent unwanted
alarms.

Operating range and alignment angle

The GDU-01-TT can electronically transmit ultrasonic waves over a long distance. However, it typically has a narrow field of response when used in conjunction with an ultrasonic detector due to the nature of electronically emitted sound.
Figure 4-4 shows the recommended angular alignment of the GDU-01-TT to the sensor face for maximum output.

Figure 4-4: Operating Distance and Angular Alignment

A. Detector sensor face

You can effectively use the GDU-01-TT at a range of up to 8 m, but take ultrasonic background noise into account before using the GDU-01-TT to verify detector operation. A higher ultrasonic background noise will reduce the GDU-01-TT’s effective range.

Using accessories

Emerson recommends attaching the shoulder strap to the GDU-01-TT with the fastening clips before using it.

Charge the battery

If the Battery Low indicator illuminates when you turn on the GDU-01-TT, Emerson recommends fully charging it before use.

Procedure
Plug the charger into the charging socket (orientation tab ensures correct polarity) and charge for eight hours to ensure the full charge cycle. Ensure that the rotary switch is in the Off position to ensure that the transmitter fully charges.
The mains connector illuminates to show power is connected, and the battery charge indicator will illuminate to show the charge cycle has began. When the battery charge indicator goes off, the charge cycle is complete.

Troubleshooting

The GDU-01-TT cannot be repaired in the field.
In the event of a GDU-01-TT failure (i.e., user interface indicators failing to light, charging problems, or loss of ultrasound emission), please consult your Emerson representative.
