5.4. System limits for the RIOTRONIC X+ Blaster
A single RIOTRONIC X+ Blaster can communicate and initiate a maximum of 500
RIOTRONIC X+ detonators. A network can be set up to increase that number of detonators
to 2500. This network would consist of a master Blaster controlling 5 slave Blasters.
For any shot requiring more than 2500 RIOTRONIC X+ detonators, please contact TAP or
your agent.
5.5. General planning for connection
Cross talk between BUS LINE circuits is only possible if the BUS LINE of different circuits is
run in parallel and in proximity (less than one centimeter) over a long distance. To avoid
cross talk between the BUS LINE of different RIOTRONIC X+ Logger circuits, each
RIOTRONIC X+ Logger circuit must always be run separately. A distance of a few
centimeters is enough to avoid cross talk between different circuits.
In quarrying or open cut operations, this is usually not a problem. In underground mining
operations or tunneling, where the environment is much more confined, special efforts must
be made to comply with this rule.
Therefore, follow these rules:
Never run the RIOTRONIC X+ Logger circuits in parallel and near each other.
Never put the RIOTRONIC X+ Logger and BUS LINE circuits in a bunch, wrapping
them around pins in the side wall.
Never run several RIOTRONIC X+ Logger circuits through a telephone or multi pair
conductor cable.
Always put the RIOTRONIC X+ Loggers in a safe place away from the blast. Ensure
that the BUS LINE wire is not under tension.
5.6. Before shot
Always make sure all mine personnel is safe and the site is cleared before the RIOTRONIC
X+ Blaster is connected to the bus line and the programming sequence is initiated.
In case the blast must be aborted either during or after programming the RIOTRONIC X+
detonators, always wait for at least FIFTEEN minutes before returning to the blast site.
5.7. Conditions for setting up a shot
Depending on special conditions (nature of the rock, presence of water in rock mass, drilling
conditions, installation of charges …), the operator may have to take extra precautions.
