Thomas BM175-10PT Programmable Sequential Blasting Machine Pack

General Information

    The REO ST and PT series Sequential Blasting Machines are modern easy-to-use programmable timing machines meeting the special requirements of bench blasting operations while precise millisecond/microsecond accuracy is critical.
    Programmable timing permits the blaster to take full advantage of the greater accuracies offered bt the new electronic detonators to achieve better fragmentation and to control ground vibration.  The REO Sequential Blasting Machines allow the blaster to continue full production blasting which otherwise would be drastically curtailed if a single circuit machine were employed.
    The REO Sequential Blasting Machines are of solid-state capacitor-discharge design with 10 circuits that fire one after the other sequentially at preselected time intervals from 1 to 999 milliseconds in 1 millisecond increments.  For special requirements, timing selection increments of 100 microseconds to 10 milliseconds are offered.
    The BM175 and BM225 series Blasting Machines are 450 volt output models and are recommended for most applications.  These models have a cable receptacle on the top panel and require an EC15 series Extension Cable and TB15 Terminal Board to connect to the detonator lead lines.
    The timing interval between circuits on the BM175-10ST Blasting Machine is selected and set on a single switch, and the selected timing is Identical between each circuit.
    The timing intervals between circuits on the -10PT series Blasting Machines are selected and set independently on each of nine switches (ten switches on slave models), and the selected timing may be Different between each circuit.
    The -10PT series Blasting Machine is available in Master and Slave models for applications that require more than 10 circuits.  Up to fifteen ten-circuit Slave units can be added as needed.
    The BM175 and BM225 series Blasting Machines are available in two Remote models.  The -10PT-RC series operates from the battery powered RC70 Remote Control.  The -10PT-RM series operates from mains power.
    Several models that bypass open circuits (BOC) are offered for BOCAR (Bypass Open Circuit Automatic Redundancy) blasting methods.  All models are available with a Key feature.
    The -10PT series Blasting Machine is available with a Trigger Output that provides and optically isolated output when circuit 1 fires.

Operation

    Use of this equipment requires training in sequential blasting techniques.  Contact your powder company representative for training information.  This equipment must be operated in accordance with US Federal health and safety standards, state laws, rules, and other applicable statutory provisions.
Suitability:  Properly trained and skilled personnel must determine suitability and safety factors of each blast.
Important:  Devices such as the REO Blasting Machine Energy Testers must be used to determine the energy output of each circuit prior to each blast.  The extension cable shall not be connected to the blasting machine until the circuit wiring has been verified by approved testers, the blast is ready to be fired, and area safety is assured.
    After the blasting circuits have been connected to the blasting machine, depress the Charge switch and hold it down.  When the Ready to Fire indicator lights, depress the Fire switch while continuing to depress the Charge switch.  Unless the Charge and Fire switches are operated together, the machine will not fire.  The Cap Circuit indicators, when lit, indicate the probability that circuit fired.  The machine will stop firing at an open circuit, except -BOC series Blasting Machines which continue sequencing even if a circuit is open.

Master-Slave Configuration

    The -10PT series Blasting Machines are available as a master or slave.  Up to fifteen slaves may be connected to the master to provide up to 160 detonator circuits (10 on the master and 10 on each slave) as required.  The slave(s) receive the charge and fire signals from the master.  The programmable timing between circuits is selected on the master and slave(s) as needed.

Remote Configuration

    Four remote models are available.  The BM175-10PT-RC and BM225-10PT-RC operate up to 2000 feet from the RC70 battery operated remote control using 20 gauge or heavier duplex wire.  The BM175-10PT-RM and BM225-10PT-RM operate from 200/250 volts, 50/60 Hz mains power.

Battery Life
   
    A lighted Ready to Fire indicator confirms that the battery power was sufficient to charge the capacitors to the design voltage and the safety circuit is released.
    The amount of time it takes for the Ready to Fire indicator light to illuminate reflects remaining battery life.  After months of use, a longer charge time will be required.  However, regardless of battery condition, the full design voltage is present and the unit's safety circuit is released if the Ready to Fire indicator is illuminated.

General Information

The REO Blaster's Ohmmeters provide nominal values of circuit resistance on a large easy-to-read digital display.  The user-friendly ohmmeters speed up circuit check-out and provide vital information necessary to assure a successful blast.  Long battery life, rugged water resistant enclosures and heavy duty terminals provide the blaster with a dependable ohmmeter that provides years of service.  The B0199.9-10 (0 - 199.9 ohms) and the B01999-1 (0 - 1999 ohms) Blaster's Ohmmeters are pocket-sized single circuit models designed for general use.  A nylon cord attatched to the case allows the ohmmeter to hang from around the neck for convenient use.  The B0199.9-10 (0 - 199.9 ohms) and the B01999-10 (0 - 1999 ohms) Blaster's Ohmmeters are ten circuit models designed for REO Sequential Blasting Systems and include a special set of terminals for single circuit testing.  The sequential blasting cable is connected to a socket on the ohmmeter thus allowing rapid resistance measurement of each circuit selected by a rotary switch.
