System Safety Feature
Once Armed, the Detonator Units must be sent a Fire
command within 60 seconds. If the Detonator Units do not receive a Fire command
within 60 seconds of being armed, they will automatically Disarm. The firing capacitor
will be safely internally discharged, the binding posts will remain isolated from the firing
capacitor and the binding posts will remain shunted together.
5.5.8.
To Arm the selected Detonator Units, press the “ARM” switch. The red
ARMED light next to each selected Detonator Unit switch will flash for 10 seconds, and
then come on steady for two seconds. ARMED lights for selected Detonator Units that
the Controller Unit did not receive a status message from will begin to flash again. The
selected Detonator Units are now assumed to be ARMED! For unconfirmed
communications, count to 10 from when the "ARM" switch is pressed and assume the
Detonator Units are Armed.
5.5.9.
To Fire the Detonator Units, press the “FIRE” switch. The operator should get
an indication of shot initiation. The ARMED light will go out and the green DISARMED
light for each selected Detonator Unit will flash on the Controller Unit display panel.
5.5.10.
If not all the Detonator Units were selected for the shot, repeat above steps to
initiate the remaining shots.
5.5.11.
To Disarm any Detonator Units that have been Armed, select Detonator Units
and press the “DISARM” switch. All selected Detonator Units will return to the
DISARMED mode in approximately 3 seconds.
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.
5.5.12.
Turn off the Controller Unit.
5.5.13.
Recover the fielded Detonator Units.
5.5.14.
Refer to Post Operational Procedures in chapter 6.
