1673 OPERATION MANUAL REV A 1 1. INTRODUCTION 1.1. THEORY OF OPERATION 1.1.1. The Remote Firing Device (RFD) is used to activate both electric and non-electric detonator devices. The system is strictly an electronic device, containing no explosive. The Remote Unit is placed at the explosive site, with a shock tube or the electric detonator firing cable running to the detonator(s). The Controller is placed at the intended firing position. 1.1.2. Using remote control technology allows the blaster to increase his standoff distance for maximum safety. With the blaster unconnected to the firing line, he is free to move around to achieve both the safest firing position, as well as the preferred viewing position. Blast efficiency is improved as the consumption of non-electric lead-in-line is reduced by as much as 90%. In subsurface operations, safety is achieved when all headings are fired from one position with all personnel above ground. Significant cost savings may be found in comparison to expensive mains firing systems. 1.1.3. Critical features of this Remote Firing Device over other systems are the two-way communication link and the timed automatic-disarming function. The two-way communication feature provides a high degree of safety, by allowing the blaster to verify that each Remote Unit is disarmed before approach. The automatic-disarming function ensures that the unit returns to a safe state in the event of a loss of communications, after a time out period. 1.1.4. In subsurface operations, safety is achieved when all headings are fired from one position with all personnel above ground. Significant cost savings may be found in comparison to expensive mains firing systems. The motion detection feature can be used to help determine if the blast has been initiated successfully. 1.2. STORAGE AND ENVIRONMENTAL CONDITIONS 1.2.1. The Controller Unit and the Remote Unit cases (with lids closed) are airtight, watertight, and dustproof. The Remote Unit should normally be operated with the lid closed and fastened. The internal case contains the circuit electronics and should remain sealed. 1.2.2. The Controller and the Remote Units are shock resistant and will handle considerable abuse. They have been drop tested from 6 feet (1.8 m) onto concrete. 1.2.3. The Remote Unit firing terminals are electrically isolated from the firing energy at all times except when firing. 1.2.4. The RFD system should be stored in a cool, dry place. The storage temperature range is -4 to 86 F (–20 to 30 C). Exceeding the storage temperature range may result in damage to the internal battery packs.

1673 OPERATION MANUAL REV A 2 1.2.5. The maximum operating temperature range of the RFD is –22 to 140 F (-30 to 60 C). 1.2.6. The battery chargers are for indoor use only. Charge time is approximately 3 hours. Minimum Temperature Maximum Temperature Operate -22 F (-30 C) 140 F (60 C) Store* 41 F (5 C) 77 F (25 C) Charge 32 F (0 C) 104 F (40 C) Table 1-1 RFD Temperature Ranges *Exposure outside of this temperature range may result in decreased battery life or damage to the internal battery packs.

1673 OPERATION MANUAL REV A 3 2. RFD SYSTEM COMPONENTS 2.1. CONTROLLER UNIT Figure 2-1 Controller Unit 2.1.1. Figure 2-1 shows the Controller Unit. The Controller Unit is responsible for initiation of all communications with the Remote Unit(s). The Controller Unit’s case is yellow for easy identification. 2.1.2. The Controller has an electronic key that must be installed before Arming and Firing is allowed.

1673 OPERATION MANUAL REV A 4 2.1.3. The Controller Unit is capable of commanding up to 64 Remote Units, in 8-Remote groups that are hereafter referred to as “Systems”. 2.1.4. The Controller can operate in standby for typically 12-16 hours before recharging is required. The Controller’s charger is internal and is capable of worldwide operation. Typical charge time is 3 hours. The battery system features test and discharge functions. 2.1.5. The Controller features an internal history event log which stores 1024 events in non-volatile memory. The history log can be used to obtain information on the operation and performance of the RFD. Each event is logged with the current date and time along with GPS coordinates (if available). 2.1.6. When the Electric Detonator circuit has been selected on the Controller, transmission signal levels from responding Remote Units are automatically reduced for safety around blasting caps. The Controller’s transmission signal level remains unchanged.

1673 OPERATION MANUAL REV A 5 2.2. REMOTE UNIT Figure 2-2 Remote Unit 2.2.1. Figure 2-2 shows the Remote Unit. The Remote Unit contains the fire circuits used for the initiation of detonators. The Remote Unit is normally positioned at a protected location relatively close to the blast area. 2.2.2. The electronic keys used in the Remote Unit are matched to the Controller and must be installed for communication, arming and firing. 2.2.3. The Remote Unit’s electric detonator circuit develops a minimum of 350V DC @ 5J with 27Ω of internal impedance. The maximum recommended series firing resistance (firing cable plus detonators) is 150Ω for group 1A detonators. Consult the specifications for the specific detonator that you are using.

1673 OPERATION MANUAL REV A 6 2.2.4. The Remote Unit’s shock tube circuit develops a high voltage spark to initiate non-electric shock tube. 2.2.5. The Remote Unit can run on standby for typically 12-16 hours before recharging is required. The Remote Unit’s charger is internal and is capable of worldwide operation. Typical charge time is 3 hours. The battery system features test and discharge functions. 2.2.6. The Remote Unit features an internal history event log which stores 1024 events in non-volatile memory. The history log can be used to obtain information on the operation and performance of the RFD. Each event is logged with the current date and time along with GPS coordinates (if available). 2.3. BATTERY CHARGERS 2.3.1. Both Controller and Remote Units use internal battery chargers which are powered by +12VDC from an external AC adapter. The AC adapter operates from 100–240VAC, 50-60 Hz, and has changeable pins for worldwide operation. Typical charge time is 3 hours. Charging should be conducted indoors. Do not attempt to substitute another power supply or equipment damage may occur. 2.3.2. For battery charging procedure, refer to Section 3.2. 2.4. ENABLE KEYS 2.4.1. Each system is supplied with a unique group of enable keys. The enable keys contain the encoded information required for operation. 2.4.2. The Controller Unit has a unique enable key, and will only arm and fire with this specific key installed. The Controller Unit will perform status and disarm functions without the key installed. The Controller Unit automatically disarms all Remote Units upon key removal. The Controller key is labeled with a ‘C’ to distinguish it from the Remote keys. 2.4.3. The Remote Units’ use of the enable key can be configured for one of two operation modes. 2.4.3.1. In generic (default) mode, the Remote unit assumes its System and Unit numbers from the key installed. Any key can work in any Remote unit (as long as that Remote is on the correct frequency assignment). Generic mode allows the flexibility to move Remote Units within different systems and units within those systems by changing the keys. 2.4.3.2. In dedicated mode, The Remote Unit is setup to only work with one specific key; for example a Remote Unit setup in dedicated to be Remote #3 from System #8 can only work with a key that matches these values. Dedicated mode can help when a very strict key control plan is required.

1673 OPERATION MANUAL REV A 10 2.7. CONTROLLER LCD DISPLAY 2.7.1. The LCD display provides information that is supplemental to the basic operation of the 1673 RFD. The LCD is rated for -20 to 70 ºC (-4 to 158 ºF). At low temperatures, the LCD may unreadable. In most cases, the standard LED indicators are sufficient to complete blasting operations. In the event the display becomes unreadable due to low temperature, normal display operation should be restored as the unit comes back within the normal temperature range. 2.7.2. Whenever a switch is pressed, the LCD display’s backlighting function will be enabled. After 30 seconds of inactivity, the backlighting will automatically turn off to save battery power. 2.7.3. When the Controller is turned on by pressing the ‘ON’ switch, The Controller goes through a series of self-tests. Once the self-testing is complete, The Controller will show the default screen of Figure 2-5. Figure 2-5 Controller Unit Default Screen 2.7.4. UNIT TYPE: This informs the user this is a Controller Unit (yellow box). 2.7.5. GPS ACCURACY: If the unit is equipped with GPS, data received from satellite signals are used to record date, time, and positional information in the history log. The GPS accuracy is a number (0-3) which represents the calculated accuracy of the reported data. A GPS rating of ‘0’ indicates GPS has not been acquired. The highest rating of ‘3’ indicates an accuracy of approximately 3 meters (10 feet) and the recorded positional data is considered ‘data ok’. GPS takes approximately 1 minute to acquire after the unit is turned on. GPS signals are not available in underground installations, inside vehicles, or where the unit is surrounded by metal. The GPS unit will remember the date and time when no signal is available. You can check the actual GPS

1673 OPERATION MANUAL REV A 11 information on the Normal menu by choosing option ‘3’. Units that are not equipped with GPS use a separate clock for recording the date and time of events in the history log. 2.7.6. SYSTEM SELECTED: This is the active System # that is currently selected. You can change to select a different System # on the Normal menu by choosing option ‘2’ and entering the number of your desired System (1-8). The Controller is capable of commanding up to 8 Systems, but it can only command one system at a time. Each System contains up to 8 Remote Units, for a total operational capability of 64 Remote Units. 2.7.7. CURRENT BATTERY VOLTAGE: This represents the current state of charge of the unit. It is recommended that the unit be recharged when the battery falls below 7.5V. The unit will operate normally down to 7.0V however below this the unit must be recharged. If you are operating this system at a temperature below freezing, it is recommended that you fully charge before use. The batteries will start to lose capacity below 0 ºC (32 ºF). A more thorough battery test can be performed by pressing the BATT TEST switch. Below 7.0 V the yellow POWER light begin flashing. 2.7.8. KEY PRESENT: This indicates that the Electronic Key is installed is the correct key for your Controller. The Controller can only be matched to one key at a time. An error will be indicated if a different key or if a faulty key is installed. The yellow KEY light in the SYSTEM indicators also lights solid when the correct key is installed, but will blink if an incorrect key is installed. The Controller’s key must be present to allow arming and firing. Other operations such as status and disarm may be performed without the Controller’s key installed. The Controller’s key should be stored in a secure place away from the Controller when you are not actively engaged in blasting activities. Without the Controller’s key, the Controller is incapable of arming or firing the Remote Units. Note: Removing the Controller’s key will cause it to select and send a disarm command to all Remote units of the currently selected system. Avoid removing the Controller’s key when the Controller is on, unless you intend to disarm all Remotes. Normally this would be in a panic situation. 2.7.9. FIRING MODE (FM): ST indicates the Shock Tube Initiator circuit is selected. ED indicates the Electric Detonator circuit is selected. When arming and firing, the current selection will be used. The Controller remembers the last mode selected the next time you turn it on. You can change the Firing Mode selection on the Normal menu.

Figure 2-10 shows that this unit is #2. 2.10.6. GPS ACCURACY: If the unit is equipped with GPS, data received from satellite signals are used to record date, time, and positional information in the history log. The GPS accuracy is a number (0-3) which represents the calculated accuracy of the reported data. A GPS rating of ‘0’ indicates GPS has not been acquired. The highest rating of ‘3’ indicates an accuracy of approximately 3 meters (10 feet) and the recorded positional data is considered ‘data ok’. GPS

1673 OPERATION MANUAL REV A 20 takes approximately 1 minute to acquire after the unit is turned on. GPS signals are not available in underground installations, inside vehicles, or where the unit is surrounded by metal. The GPS unit will remember the date and time when no signal is available. You can check the actual GPS information on the Normal menu by choosing option ‘3’. Units that are not equipped with GPS use a separate clock for recording the date and time of events in the history log. 2.10.7. CURRENT BATTERY VOLTAGE: This represents the current state of charge of the unit. It is recommended that the unit be recharged when the battery falls below 7.5V. The unit will operate normally down to 7.0V however below this the unit must be recharged. If you are operating this system at a temperature below freezing, it is recommended that you charge before use. The batteries will start to lose capacity below 0 ºC (32 ºF). A more thorough battery test can be performed by pressing the BATT TEST switch. Below 7.0 V the yellow POWER light will flash. 2.10.8. SYSTEM NUMBER: The system number is read from the Remote Unit’s electronic key and is display on the LCD.

FIRING MODE (FM): ST indicates the Shock Tube Initiator circuit is selected. ED indicates the Electric Detonator circuit is selected. When arming and firing, the current selection will be used. The Controller saves the currently active selection when turned off. Figure 2-11 Remote Unit Electric Detonator Armed Screen 2.10.11. f.

1673 OPERATION MANUAL REV A 21 2.10.12. Figure 2-11 shows the screen that is displayed on the Remote Unit when its Electric Detonator circuit is armed. The CHARGE STATE will initially display ‘Charging’ as the firing capacitor voltage begins to rise. As the capacitor becomes fully charged, this will change to ‘Charged’ and the red ARMED light on the front panel will also turn on. The REMAINING ARM TIME will be displayed as minutes: seconds as it counts down to zero. When it reaches zero, the capacitor will discharge internally and the unit will return to READY or disarmed state. The CAPACITOR DC voltage will also be displayed while the unit is armed. This value will be continuously updated to show the true value of the capacitor voltage. Figure 2-12 Remote Unit Shock Tube Initiator Armed Screen 2.10.13. Figure 2-12 shows the screen that is displayed on the Remote Unit when its Shock Tube Initiator circuit is armed. The UNIT STATE will display ‘Armed’ and the red ARMED light on the front panel will also turn on. The REMAINING ARM TIME will be displayed as in minutes : seconds

1673 OPERATION MANUAL REV A 22 as it counts down to zero. When it reaches zero, the unit will return to READY or disarmed state. The firing capacitor is not charged while the unit is armed, but as the unit is in the act of firing. After firing, the capacitor voltage will be briefly reported as the unit disarms back to the READY state. 2.11. SHOCK TUBE FIRING TIP 2.11.1. Shock Tube Initiation. The shock tube initiator circuit ignites the explosive powder contained inside of the shock tube creating a dust explosion which transverses through tube at a high rate of speed toward to the detonator. The Remote Unit develops a high-energy spark at the igniter needle located in the Igniter Port shown in Figure 2-13 of the firing tip. Care must be taken to ensure no water or moisture is allowed on or near the igniter needle, or misfires may occur. Keep the tip clean and dry before use and keep the shock tube ends capped at all times. Once the shock tube is installed onto the igniter needle, the unit may be operated in the rain. Figure 2-13 Firing Tip, Shock Tube 2.11.2. Shock Tube Installation on Firing Tip. Figure 2-13 shows the shock tube firing tip and how the shock tube is installed. 1. Make a fresh cut with a sharp knife removing the last 6 inches of shock tube. 2. Insert the shock tube through the guide hole on the tip as shown in Figure 2-13. The guide hole secures the tube to the tip and prevents pulling out.

1673 OPERATION MANUAL REV A 23 3. Insert the tube into the igniter port on the side. Slide the tube into the igniter port until the tube comes to a firm stop. 4. Pull the tube exiting the guide hole, removing any slack in the loop formed. This prevents the tube from coming loose from the igniter needle. Do not allow the tube to form a kink. 2.11.3. Tip Care. The two tips provided with the RFD are rugged, and will each last for up to 500 shots if properly cared for. Take care to keep mud and debris from getting on the igniter needle. In some cases, the tip’s life can be extended by washing in soapy water and gently rubbing the igniter needle with a non-metallic device such as a cotton swab. 2.11.4. Tip Replacement. It is recommended the tip be replaced at regular intervals to prevent the likelihood of misfires resulting from worn tip electrodes. You may choose to hold one tip in reserve as a replacement or spare at a location apart from your RFD. Then estimate your tip usage, and schedule replacement when the tip’s use reaches your estimated 500 shots.

Service Menu allows changes of various to critical operation parameters such radio settings, calibration, and arm time. Consult the manufacturer or distributor if you feel you need to have adjustments to your system. 5.7. FACTORY MENU 5.7.1. Factory Menu is a PIN protected mode where change can only be performed by the manufacturer. 5.8. PROGRAMMING ELECTRONIC KEYS 5.8.1. The Key Programming Mode of the Controller allows you to create replacement keys if you have a lost or damaged key, or you can create a new key if you need to add a new Remote to your system. An important feature of the key programming mode is that it will not allow duplicate keys to be created. This means that if a key is lost or stolen, once you reprogram the keys, the key that was lost or stolen will no longer be functional, unless it also is reprogrammed. 5.8.2. When programming a key associated with a particular system, you must also reprogram all of the other keys associated with that system at the same time (up to 8 Remotes and the Controller key must be programmed together). You do not need to reprogram keys that are associated with other systems, unless you are adding or replacing their keys as well. 5.8.2.1. Identify which systems (1-8) the new or replacement keys will be matched to. If you have 8 Remotes or less, by default you will be reprogramming only the System #1 keys. If you have more than 8 Remotes, you may be programming keys from other Systems as well. 5.8.2.2. Gather all of the keys associated with the system(s) for which you have identified in 5.8.2.1 to the Controller Unit. You must reprogram all Remote Units from that system together at the same time; even the ones that are working correctly. 5.8.2.3. Remove the Controller’s key from the electronic key port. Turn the Controller on, and press the MENU switch to enter the start menu. 5.8.2.4. Press ‘2’ to select the Advanced Menu. Enter the PIN supplied to you by the manufacturer or distributor.

Normal maintenance is limited to periodic battery charging and cleaning the outer surfaces and panels with a damp cloth removing dirt and debris. Ensure the CHARGE/PROGRAM, ELECTRONIC KEY port, and firing terminals are clean and dry with a cotton swab. Check for signs of corrosion around and on connector pins. Ensure the electric detonator firing terminals are clean, and easy to depress. 8.1.2. Scheduled Maintenance. It is recommended that the 1673 RFD be returned to the manufacturer or an authorized service shop every two years for periodic maintenance. At this time the latest improvements are added, fresh battery packs are installed, the radio transceivers are tuned and verified, and the overall performance of the RFD is thoroughly tested. 8.1.3. Corrective Maintenance. Corrective maintenance should be performed at the manufacturer or an authorized service shop only. Replacement of parts or repair at the user level and field disassembly is strongly discouraged and may result in death, injury, or unsafe equipment operation. The Remote Unit contains dangerously high voltage levels when armed. 8.1.4. Battery Maintenance. Your RFD contains heavy-duty 7.2V NiMH battery packs that should be replaced after 500 charge/discharge cycles or every three years, whichever comes first. If a decrease in run time has developed, there may be a memory problem caused by repeated shallow discharges or interrupted charge cycles. 8.1.5. Battery Condition (Discharge). To keep the battery packs running optimally, it is recommended that you perform a full discharge before recharge using the discharge feature of the at least once per month. To perform a Battery Condition, connect the Charger Power Supply to a wall outlet, and connect the cable connector to the CHARGE/PROGRAM connector. Turn the unit on and then press and hold the ‘BATT TEST’ switch for 5 seconds. The unit will discharge the battery to a low level and then it will be recharged. The whole process takes up to 10 hours to complete. Always ensure the power supply is connected and working before discharging. Figure 8-1 Battery Condition (Discharge Battery)

1673 OPERATION MANUAL REV A 54 8.1.6. Tip Care. The two shock tube igniter tips provided with the RFD are rugged, and will last for 500 or more shots if properly cared for. Take care to keep mud and debris from getting on the igniter needle. In some cases, the tip’s life can be extended by washing in soapy water and gently rubbing the igniter needle with a non-metallic device such as a cotton swab. 8.1.7. Tip Replacement. As the tips are used, the electrodes will wear and eventually become unreliable. Therefore, it is highly recommended that your company adopt a strict tip replacement/tracking plan. Tip usage can be tracked using the serial number engraved on the tip. Discard each tip when its usage reaches 500 shots. Always hold a replacement tip handy. You may also dry fire the old tip and compare it to the sound and spark intensity of a new tip. If the old tip’s spark is noticeably weaker, replace it.
