Pre-Blasting Diagnostic Features

An infrared link executes the transfer of the blasting plan from the programming unit to the blasting machine. The blasting machine will carry out the following operations leading to the firing:

• Short circuits and non-connected firing lines are verified
• System checks for missing and extra detonators,
• All functions of each individual detonator are checked,
• One-to-one mapping between blasting plan stored in the blasting machine and detonators is checked on line

In case of any malfunctions an error message is displayed and corrective measures are suggested:

• Operator then arms all detonators in the round by turning and holding the charge key.
• Fire switch lights up, the operator depresses the fire switch while still holding the charge key. The blasting machine will only operate when the charge key and the fire switch are triggered simultaneously
