ZERO180 Gun System

Caution:

It is recommended to handle one detonator at a time

to minimize the hazards; furthermore, arm each gun individually

from the top of the gun string working towards the bottom to reduce

exposure and risk.

5.1 Remove an Austin Powder A-140F detonator from its storage container and packaging.

Discard the plastic detonator block; it is not required for this system.

5.2 Place a pencil at the wire end of the detonator. Bend the detonator lead wires around the

pencil back to the body of the detonator taking care not to pull on the wires. Secure the wires

to the body of the detonator with 2 – 3 wraps of electrical tape around the wires and detonator.

Do not cover the uid holes of the detonator. Bend the wires back in their original direction.

This step will prevent you from pulling the lead wires directly on the end of the detonator.

5.3 Insert the detonator into a detonator safety tube and secure the lid closed.

5.4 Remove the electrical shunt from the wires and verify the resistance of the meter with a

blaster’s multimeter or blaster’s galvanometer. The resistance of the detonator should read

between 50 and 60 Ohms.

5.5 Through the port, electrically connect the ground wire of the gun to the purple wire of the

detonator. Since this is the ground no insulation of the connection is necessary. Keep the

wires as short as possible to allow room for all connections in port and prevent knicked or cut

wires.

5.6 Also through the port, electrically connect and insulate the wire from the switch/diode to the

red wire of the detonator. Keep the wires as short as possible to allow room for all connections

in port and prevent knicked or cut wires.

5.7 The detonator is fully connected electrically. Remove the detonator from the detonator safety

tube. Insert the detonator, output end rst, through the port and into the 9/16” hole in the sub.

(It is important to use sub 30-079-0002-95 as it has the correct connement for lap splice

initiation.) The detonator is positioned next to the det cord and is now ballistically armed.

5.8 Carefully tuck the new connections into the bottom of the port.
