The BMM transmitter must be switched on before installation into the blast. The BMM can only be switched on by a specially coded signal which eliminates accidental activation. The BMM Activator (Activator) is a remote control device that provides the signal to turn a BMM on and to also assign a delayed start-up time if required. It is also useful to quickly determine if a BMM is transmitting. The signal from the Activator is low power to limit its range to approximately 0.5 m. This is to control which BMMs are switched on. WARNING All BMMs that are within range of the Activator will switch on when the BMM On button is pressed. Ensure other BMMs are well out of range (several metres to be certain) of the BMM to be turned on or programmed. Do not play with the Activator anywhere near BMMs. Store BMMs in a separate location to the Activator 2.1 Hardware 2 USING THE BMM ACTIVATOR The Activator consists of a tough ABS plastic case with a sealed low-profile keypad. The battery compartment can be accessed by pressing and sliding a section at the back of the case. Use a good quality 9 V alkaline or rechargeable Nickel Metal Hydride (NiMH) battery. The BMM System kit is supplied with an Aquapak. It is a transparent case that is 100% waterproof when closed. It has a cord for hanging around the users neck, which frees up hands for other tasks and eliminates the chance of dropping the Activator into a blast hole. It is strongly advised that the Activator be placed inside the supplied Aquapak and hung around the users neck. www.bmt.com.au BMM System Manual BMM Activator 2 2.2 Quick Start Turn the Activator on by pressing the Power button . The digital display will quickly show the battery voltage, and then show 00. Once less than 8.5, it is close to flat so have a spare battery available. Press the yellow 1 or 10 button to select the desired start-up delay time in multiples of 4 hours up to a maximum of 36 hours. The display shows the actual delay in hours. Position the Activator close to the BMM to be switched on (within 100 mm), and press the green BMM On button briefly the green
(transmit) LEDs will illuminate briefly. Activation is more reliable if the Activator is pointing down at the BMM (approx. 45) as shown in the photo in Section 2.1. If the transmitter switches on, the red (receive) LEDs will illuminate and an audible tone will be generated at regular intervals (beep, beep, beep, beep). Keep the Activator within range of the BMM for at least ten seconds, to make sure the BMM continues to transmit. As a final check to make sure the BMM is still transmitting, move the Activator out of range of the BMM and then back within range. If the BMM does not turn on, the respective transmit and receive aerials may be unfavourably orientated, so move the Activator around the BMM by 90 and try again. WARNING The BMM cannot be switched off once activated In the future, the BMMs will be able to be assigned an ID code that will make each one uniquely identifiable in a blast. The Type 5 Activator has been designed with this feature but it is not enabled at this time. www.bmt.com.au BMM System Manual BMM Activator 3 2.3 Test Button The Test function only confirms that the BMM is functioning by turning it on briefly. It is not necessary to use this during normal use and it is best to avoid using this function onsite. If Test Mode has to be used to confirm a BMM is functioning, position the activator as previously described and press the grey Test button (the display can be any number). The BMM will then transmit for about five seconds and then turn off, ready to be switched on normally. 2.4 Delayed Start-up The BMM transmits at constant power for about 10 12 hours so to accurately calculate the depth of the BMMs after the blast, they must be located within this period. The BMM will continue to transmit for about 24 hours beyond this time (total ~36 hrs) but the signal will slowly decrease and eventually switch off. If the BMM is located after the initial 10 hr period, its horizontal location will be accurate but not its depth. The delayed start-up feature was specifically designed for mines that could not access the muckpile immediately after blasting due to light and/or safety reasons. It can also be used to install the BMMs well before the blast for operational reasons. Once activated with a delayed start-up, the BMM with transmit for approximately 15 minutes before switching off and sleeping for the requested period. At the end of the delay period, it will transmit normally until the battery goes flat just as it does with zero delay. Refer to the Monitoring Procedure Manual for more information about how the delayed start may be used. Delays can be set in multiples of 4 hours, up to 36 hours. The displayed number is the actual delay in hours, which is different to the old Type 4 Activator. WARNING Once a BMM is activated for delayed start-up it cannot be changed. That is, it cannot be switched off nor be made to switch on earlier or later. 2.5 Miscellaneous The BMM Activator is also useful to quickly determine if a BMM is transmitting since the red receive LED will illuminate intermittently with sound whenever a BMM signal is detected. www.bmt.com.au BMM System Manual BMM Activator 4 3 TROUBLESHOOTING Fault Solution The Activator wont turn on Check the status of the battery and replace as necessary. The display turns off during Low battery replace operation BMM wont turn on Change proximity of Activator and transmitter and try againand again. Confirm that the green button is depressed until the transmit LEDs flash. Install an appropriate fresh battery. The transmit power may be below the required threshold. The BMM transmitter may be faulty. Set it aside, mark it appropriately and contact BMT. 4 SPECIFICATIONS Battery Type: 9V PP Alkaline or rechargeable NiMH Transmission frequency: 111.1 KHz Equivalent Isotropically Radiated Power (EIRP): 2.5 W www.bmt.com.au Copyright 2005-2012 Blast Movement Technologies All rights reserved.
