2.3.6.
Disarm the Detonator Unit
. Depress the “DISARM” switch, the Controller
Unit will transmit the Disarm command to selected Detonator Units. Selected Detonator
Units will internally discharge their firing capacitor. Selected Detonator Units that
receive the Disarm command will become Disarmed within 3 seconds of receiving the
command. The green DISARMED light for selected Detonator Units will begin to flash
on the Controller Unit display panel. The Controller Unit will then request status of
selected Detonator Units. If the Controller Unit is within range of the selected Detonator
Unit transmitter, the green DISARMED light for that Detonator Unit will turn to steady on
the Controller Unit display panel. If the Controller Unit is out of range of the selected
Detonator Unit transmitter, the green DISARMED light for that Detonator Unit will
continue to flash on the Controller Unit display panel. If the Fire command is not sent
within 60 seconds of Arming, the system will Disarm automatically.
CAUTION
Do not assume the Disarm command has been received by the
Detonator Unit unless DISARMED status is confirmed with a steady DISARMED light
for that Detonator Unit on the Controller Unit display panel. If distance appears to be
the problem, move closer to the Detonator Unit following standard procedures for this
type of situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedly
as the Detonator Unit is approached. Maintain a safe distance from the Detonator Unit.
Do not approach the Detonator Unit until Disarmed status is confirmed with a steady
DISARMED light for that Detonator Unit on the Controller Unit display panel. Under no
conditions should the “FIRE” switch be pressed as the Detonator Unit is approached.
Do not bring the Controller Unit closer than 100 feet to blasting caps, wires connected to
blasting caps, or other explosives.
2.3.7.
Activate the Detonator Unit Firing Circuit
. Depress the “FIRE” switch for
1/2 second and the Controller Unit will transmit the Fire command to selected Detonator
Units. If the “FIRE” switch is pressed during the firing capacitor charge time, the
Controller Unit will wait until the Detonator Units have had time to fully Arm, and then it
will send the Fire command automatically. The Controller Unit will only transmit the Fire
command to selected Detonator Units whose status is Armed. The selected Detonator
Units will be placed in Fire Mode and discharge the firing capacitor across the binding
posts. The red ARMED light will turn off and the green DISARMED light for each
selected Detonator Unit will begin to flash on the Controller Unit display panel. The
Controller Unit will then request status from the selected Detonator Units. If the
Controller Unit is within range of the selected Detonator Unit transmitter, the
DISARMED green light for that Detonator Unit will turn to steady on the Controller Unit
display panel. If the Controller Unit is out of range of the selected Detonator Unit
transmitter, the green DISARMED light for that Detonator Unit will continue to flash on
the Controller Unit display panel.
2.3.8.
Multistage Firing of Detonator Units
. Multistage firing provides the ability
to Arm all eight Detonator Units at one time, and select any combination of the
Detonator Units to Fire at different intervals within the 60 second Arm period. The
procedure for multistage firing is :
•
Depress “1” though “8” switches.
