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 where precise millisecond/microsecond accuracy is critical.

Programmable timing permits the blaster to take full advantage of the greater accuracies offered by the new electric 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 pre-selected 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 select 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 an optically isolated output when circuit 1 fires.

* Heavy duty bare terminals accept wires, banana plugs, clips or spade terminals.

OPERATION

When using the REO B01999-10 Blaster's Ohmmeter, connect the sequential blasting cable to the CABLE connector. The ohmmeter turns on automatically. Rotate the CIRCUIT switch to positions 1 through 10, noting the resistance displayed for each circuit. 1 will be displayed if the resistance exceeds the full scale range of the ohmmeter. To measure the resistance of a single circuit, connect the blasting circuit to the SINGLE CIRCUIT terminals and rotate the CIRCUIT switch to the SINGLE position, noting the resistance displayed. The ohmmeter turns off automatically when disconnected. Replace the battery when BAT appears on the display.
