Overview Oseis System The Orica Seismic Electronic Initiating System is designed to provide accurate, secure and reliable initiation of explosives used in seismic surveys. The Oseis system consists of digital detonators and control equipment (Tester and Shooter with trigger cable). Oseis electronic detonator Oseis detonators are capable of two-way communication, highly accurate and programmable. Each detonator has a unique factory assigned identity number, which is written to the detonator microchip. This is the basis for full communication between detonators and control equipment. The unique detonator ID is printed on a flag tag and allows inventory traceabiltiy. Oseis detonators have protection structures in the electronic circuitry, which give a high level of protection against stray currents, over-voltage, static electricity and electromagnetic radiation. Oseis detonators can only be programmed and fired by Oseis Shooters, which provide the required firing energy and digital information. Oseis Tester The Oseis Tester is a handheld device used for testing of Oseis detonators and for recording the unique detonator ID and the corresponding shotpoint identifier (line and shot point number). Typically this is done when the shotpoint is loaded by the drill crew. The Tester complies with the principle of Inherent Safety. This means that the Tester is unable to fire Oseis detonators even if the Tester and the Detonator would develop faults. The Tester memory can save data for up to 300 shotpoints. The user is able to review the data stored in the Oseis Tester and to upload the data to a PC based software program called seismic-i. Oseis Shooter The Oseis Shooter is a handheld device used for firing of Oseis detonators and for recording of data. To fire the shot, the Shooter is connected to a conventional shooting system via the trigger cable. The Shooter itself is connected via the firing cable to the Oseis electronic detonator(s). Oseis Shooters are protected by a personalised identification number (PIN) to prevent use by unauthorised personnel. When the Shooter has programmed and armed an Oseis detonator, it is ready to fire and waiting for the trigger signal, a high voltage capacitor discharge impulse from a conventional radio controlled seismic shooting system. The Shooter issues the ultimate firing command upon receipt of the high voltage impulse. The delay time between receipt of the trigger signal to the detonator firing has an offset of 20 ms. The Shooter memory can save data for up to 1000 shotpoints. The user is able to review the data stored in the Shooter and to upload or download the data to a PC based software program called seismic-i. 2

1. Oseis Detonator, Tester and accessories 1.1 Oseis electronic detonator Programmable electronic detonator from 0 to 5000 ms in 0.1 ms increments.

During the self test the backlighting is always turned on. If the backlighting function is turned off, the backlighting turns off automatically, once the self test is completed. Switch off The Tester is switched off by pressing key for approximately 2 seconds in the main menu. The message Tester is shutting down is displayed in the screen, when the Tester is switched off. Note: To save battery life the Tester switches off automatically, if the operating keys are not used for 15 minutes. 7

2.5 Charging The batteries are recharged via a cable attached to the multi pin port located on the front of the Tester from any mains power source with the delivered charger (90-230V, 40-60Hz) or from a 12 V source using the optional car charger. During recharging the battery icon flashes. When the battery is fully charged the icon is steadily lit. It is recommended to store the Tester connected to the charger (trickle charge). This guarantees that the Tester is always ready for use. Dependent on the battery status it may take up to 3 hours to recharge the Tester. Note: Before the first use the Tester has to be charged for 3 hours. 8

On confirmation the Tester defaults to the main menu. 3.1.4 Erase memory To clear the Tester memory the Erase memory function is available. After selection the user will be prompted with the following warning messages: E r a s e m e m o r y? No YES Pressing of the confirmation key is accompanied by a beep: A r e y o u s u r e? No Ye S Upon confirmation with key main menu. the memory is cleared and the Tester returns to the 3.2 Log detonators For logging and testing of an Oseis detonator the legwires must be connected to the Tester output terminals, while the Tester is in logging mode, i.e. the screen must show logging det# xxx. Either wire may be inserted into either terminal, but only one wire per terminal. In cold weather the optional ring terminals may be helpful for testing the detonators. If the connection is good and the detonator responds to the Tester, the operator is reassured by an acoustic signal (3 short beeps). The Tester reads the detonator ID and also automatically carries out a leakage current measurement. The detonator number, the unique ID, status information and current leakage value are then displayed on the screen. Another beep is given when the data is accepted and saved to the memory of the Tester. The Tester offers different logging modes, which can be selected in the setup menu. To commence detonator logging, the user must select the main menu Log detonators: * * MAI N ME NU * * L o g d e t o n a t o r s 13

3.2.1 Logging and testing using manual mode OSEIS TESTER After selection of the Log detonators menu the first screen displays the user setup information (assuming that no detonator has been logged previously and the memory is cleared): MODE : M CONF : x x De t s l ogge d : 0 The upper line displays the Logging mode: Manual (Mode: M) and the confirmation option ( on: ++ or off: -- ). The lower line shows the number of logged and tested detonators saved to the memory (Dets logged: 0). Pressing key will accept the displayed information and advance to the first logging detonator screen: L o g g i n g d e t # 1 I L = x x. x m A During detonator logging and testing the Tester continuously measures the current leakage. The result of the continuous current leakage measurement is displayed in the lower line of the screen. Now the first detonator can be connected. Successful logging and testing is indicated by three short audible beeps: D e t # 0 0 1 : X X X X X X De t OK, x x. x ma The Tester displays the detonator number in the memory (det# 1), the unique ID (e.g. 6F0BD2), the detonator status (Det OK) and the current leakage (xx.x ma). Upon confirmation with key an audible beep is given, the data is saved to the memory and the next detonator can be logged and tested. L o g g i n g d e t # 2 I L = x x. x m A Key exits to the main menu. If the Confirmation off option has been selected in the setup menu, the detonator information is displayed for 3 seconds, once a detonator has been logged and tested successfully, before the data is saved and the screen is automatically advanced to the next logging detonator screen. 3.2.2 Logging and testing using manual mode with shotpoint information After selection of the Log detonators menu the first screen displays the user setup information (assuming that no detonator has been logged previously and the memory is cleared): MODE : MSP CONF : + + De t s l ogge d : 0 14

The upper line displays the Logging mode: Manual with Shot Point Identifier (Mode: MSP) and the confirmation option ( on: ++ or off: -- ). The lower line shows the number of logged and tested detonators saved to the memory (Dets logged: 0). Pressing key will accept the displayed information and advance to the first shotpoint identifier screen: L i n e S h o t p o i n t 0 0 0 0 0 0 0 0. 0 The line number (4 digits) and shotpoint identifier (4 digits and decimal) of the first shotpoint can be entered with the up or down key, the cursor position can be changed with keys (next right) and (back, next left). If the cursor is positioned on the decimal position, the step width is 0.1. In the example the first shotpoint identifier is 01010643.0. L i n e S h o t p o i n t 0 1 0 1 0 6 4 3. 0 Upon confirmation with key, the Tester advances to the logging detonator screen: L o g g i n g d e t # 1 I L = x x. x m A During detonator logging and testing the Tester continuously measures the current leakage. The result of the continuous current leakage measurement is displayed in the lower line of the screen. Now the first detonator can be connected. Successful logging and testing is indicated by three short audible beeps: D e t # 0 0 1 : X X X X X X De t OK, x x. x ma The Tester displays the detonator number in the memory (det# 1), the unique ID (e.g. 7A0ED2), the detonator status information (Det OK) and the current leakage (xx.x ma). Upon confirmation with key a beep is given and the data is saved to the memory. Now the next shotpoint identifier can be entered. The Tester automatically proposes the shotpoint identifier of the last shotpoint, if the shotpoint auto increment option is switched off. L i n e S h o t p o i n t 0 1 0 1 0 6 4 3. 0 With the up or down key (increase or decrease value) and the and key (cursor position: next right or next left) the shotpoint information can easily be changed. Each change must be confirmed with key. 15

If the shotpoint auto increment option is up, then the shotpoint number is automatically counted up (e.g. in this case to 644.0). If the shotpoint auto increment option is down, then the shotpoint number is automatically counted down (e.g. in this case to 642.0). After manual setting of the shotpoint information (e.g. to 644): L i n e S h o t p o i n t 0 1 0 1 0 6 4 4. 0 and confirmation with key the next detonator can be logged and tested. L o g g i n g d e t # 2 I L = x x. x m A Key exits to the main menu on the logging screen. On the shotpoint identifier information screen the key serves to move the cursor. Therefore the shotpoint information screen must be confirmed prior to exiting to the main menu. 3.2.3 Warning messages and trouble shooting No log The screen remains unchanged Logging det# xxx and no audible beep. If a detonator is not recognised by the Tester during the logging process the following points should be checked: - Make sure that the Tester is ready to log the next detonator. The screen should show Logging det# xxx. - Check, if the contact between the Tester terminals and the legwires is good. - Check, if the surface of the legwires are not corroded. In doubt cut and strip before retrying. - If the detonator still is not recognised take the detonator off the Tester terminals for at least one minute. By removing the detonator from the terminals the chip will reset once the capacitor has discharged. Retry after one minute. - If the detonator is still not recognised it must be replaced. Leakage current If the leakage current increase is greater then 0.5 ma upon connection of a detonator, an acoustic leakage current warning is given: 1 short, 1 intermediate and 1 long beep (instead of 3 short beeps). If a leakage current of greater than 15 ma is measured during the logging process the following message is shown: L e a k a g e c u r r e n t t o o h i g h! The warning message is accompanied by a series of audible beeps. The detonator can only be logged, when the leakage current is reduced to less than 15 ma. 16

Faulty detonator If a malfunctioning detonator is connected to the Tester the following message is prompted: L o g g i n g d e t # x F a u l t y d e t o n a t o r The detonator must be replaced. After confirmation with key can be continued with a new detonator. the logging process Incompatible detonator If a detonator with an illegal ID is connected to the Tester the following message is prompted: L o g g i n g d e t # x I n c o m p a t i b l e d e t The detonator must be replaced. After confirmation with key can be continued with a new detonator. the logging process Relog When a detonator has already been logged and the data has been saved to the Tester memory, the Tester will indicate to the operator, that the same detonator has been logged before, if it is reconnected to the terminals whilst in logging mode. The following screen appears: D E T # x x x r e l o g x x x x x x : x. x m A The upper line shows the detonator number (det# x) from the memory list, which was saved previously during the first logging process and states relog. The lower line displays the unique ID-number and the leakage current value. A series of audible beeps is given and the detonator status (Det OK) is displayed alternating with the leakage current value (x.x ma). The relog message must be confirmed with key next logging det# xxx screen. before the Tester advances to the 17

BATT BATT OSEIS TESTER 3.2.4 System limits The Tester operates at an output voltage of 6 Volts. For reliable communication between detonators and Tester each detonator must be supplied with 4 Volts. Therefore the maximum voltage drop between detonator(s) and Tester must be less than 2 Volts. Logging and and testing testing Testing prior prior to to firing firing Ensure good contacts between legwires of detonator and Tester terminals! OSEIS electronic detonator shothole Ensure good contacts between legwires of detonator and firing cable! shothole OSEIS TESTER TESTER Maximum resistance of firing cable is 100 Ohms TESTER +/- +/- During detonator logging and testing the Tester continuously measures the current leakage. If the leakage is greater than 15 ma, the Tester displays a leakage too high message. Logging and testing must be ceased to identify and eliminate the leakage source. The Tester can also be used for re-testing the detonators prior to firing at the shotpoint or via the firing cable, using the Log detonator or the Test single det function. For the use of the Log detonator function only one detonator must be connected. In contrast to this the Test single det function can also be used, when multiple detonators are connected in parallel, e.g. in a pattern shot. However, the data for the detonators to be tested must be saved to the Tester memory. The maximum resistance of the firing cable that may be used under ideal conditions (no leakage) is 100 Ohms. Current leakage on the firing cable or detonator assembly will limit the total resistance. 18

3.3 Test single detonator The Test single det function allows the user to test the attached detonator(s) which are saved to the Tester memory at the shotpoint or prior to shooting via the firing line. The function can be used while multiple detonators are connected in parallel to the firing line. * * MAI N ME NU * * T e s t s i n g l e d e t After selection of the function the connected detonator is charged up before the saved data is displayed for the first detonator in the memory. At this point the detonator has not yet been tested with the Test single det function. D E T # x x x : x x x x x x De t OK, x. x ma The user may select the detonator to be tested with the up or down key. After selecting a detonator number the test is started by pressing the confirmation key. As a result of the test the detonator status and current leakage measurement result is displayed in the screen. Should an error occur a corresponding error message, which describes the nature of the error (e.g. No reply ) would be displayed. Should the leakage current be greater than 15 ma, the Tester would beep and display the warning message current too high. Once the user has addressed the cause of the error, the function can be run again. The test will either confirm the error has been corrected by displaying a Detonator OK message, or would still display an error message No reply or Data error. Note: The test result, i.e. the detonator status and leakage current value is saved to the permanent memory. Key exits to the main menu. No reply D E T # x : x x x x x x No r e p l y x. x ma Either the detonator is not connected to the Tester terminals or the connection between detonator and terminals is poor or intermittent. If the detonator is reconnected and tested again the following screen is prompted: D E T # x : x x x x x x De t OK, x x. xma Data error D E T # x : x x x x x x Da t a e r r o r x. xma For robust communication between detonator and Tester the capacitor of the detonator must be supplied with the Tester voltage. If the capacitor is not sufficiently 19

charged a data error may occur in rare cases. This usually can be rectified by exiting to the main menu and selecting the Test single det function again, while the Tester stays connected to the legwires. 3.4 View detonators * * MAI N ME NU * * V i e w d e t o n a t o r The View detonators function allows the user to verify and edit the saved data and if necessary to change or correct the shotpoint identifier information. After selection the data list items are viewed by scrolling through the list using keys or. If the Manual logging mode has been used, the first screen displays the following user set up information in the upper line: Mod e : M CONF : x x De t s l ogge d : xx x The lower line displays the total number of logged detonators. After pressing the confirmation key the data for each detonator can be viewed: DET # x : x x x x x x De t Ok, x. x ma The user may scroll through the detonator list with keys or. If the Manual SP logging mode has been used, the first screen displays the following user set up information in the upper line: Mod e : MSP CONF : x x De t s l ogge d : xx x The lower line displays the total number of logged detonators. After pressing the confirmation key (e.g. 07010244.0): the data for each detonator can be viewed DET # x : x x x x x x 0 7 0 1 0 2 4 4. 0 The lower line shows the shotpoint identifier information. The data can be edited by pressing of the confirmation key. The cursor, which has been positioned underneath the detonator number, moves to the last digit of the shotpoint information. D E T # x : x x x x x x 0 7 0 1 0 2 4 5. 0 20

With the up or down key (increase or decrease value) and the and key (cursor position: next right or next left) the shotpoint information can easily be changed. Each change must be confirmed with key. The user may scroll through the detonator list with keys or. DET # x : x x x x x x X X X X X X X X. X If key +/- is pressed, the detonator status and leakage current value is recalled and displayed on the lower line, as long as the key is held: DET # x : x x x x x x De t Ok, x. x ma Key exits to the main menu. 3.5 Measure leakage The Measure leakage function allows the user to determine the leakage that exists on the detonator or the detonator assembly. The Tester will measure the current leakage in a range from 0 15 ma. * * MAI N ME NU * * M e a s u r e L e a k a g e After selection of the Measure leakage menu the Tester displays a charging up screen (I) followed by a display of the leakage current test result (II). (I) (II) M e a s u r e l e a k a g e C h a r g i n g u p... M e a s u r e l e a k a g e I L = x. x m A If the leakage current is in the range from 0 15 ma logging or testing can be continued, because the communication between Tester and detonator will be reliable. If a leakage current of greater than 15 ma is measured, the following message is prompted: M e a s u r e l e a k a g e I L > 1 5 m A! The warning message is accompanied by a series of audible beeps. The detonator can only be logged, if the leakage current is reduced below 15 ma. Key exits to the main menu. 21
