Refer to Post Operational Procedures in chapter 6.
5.5. SYSTEM OPERATION – DETONATOR UNITS BOTH WITHIN AND IN EXCESS
OF 1,000 FEET AND LESS THAN 5 MILES FROM CONTROLLER UNIT.
Note:
If the distance between the Controller Unit and the Detonator Units is in excess
of 1,000 feet, the Detonator Units status transmissions may not be received by the
Controller Unit. The Controller Unit will command the Detonators from a distance up to
5 miles, but the Detonator Status may not be confirmed. The Controller Unit performs
just as it would when it is within 1,000 feet of the Detonator Units. The only difference is
the method the status indications are displayed on the Controller Unit display panel.
The ARMED and DISARMED status lights for out of range Detonator Units will flash on
the Controller Unit display panel to indicate the Controller Unit did not receive a status
message from the Detonator Unit. Once the Detonator Units are set up for the shot, the
operator must assume the Detonator Units have received the command.
5.5.1.
The RFD will operate in a two-way mode (confirmed communications – range
to 1,000 feet) and one-way mode (unconfirmed communications – range up to 5 miles).
5.5.2.
If the Detonators are within 1,000 feet of the Controller Unit, the status of the
Detonator Units (ON/LOW BATT, ARMED, and SAFE) will be displayed with solid lights
on the display panel of the Controller Unit.
5.5.3.
If one or more Detonator Units are out of range of the Controller Unit, the
status of these Detonator Units will be assumed and their status lights will flash on the
Controller Unit display panel to indicate unconfirmed status. Accordingly the operator
must assume the following:
•
Commands have been received by the Detonator Units.
•
The Detonator Unit battery is sufficiently charged to activate the firing circuit.
•
A “DISARM” command should not be assumed.
5.5.4.
Ensure the area is clear.
5.5.5.
Turn the Controller Unit on.
5.5.6.
Press the “STATUS” switch. The Controller Unit will request status from all
Detonator Units. The red TX light will flash for approximately 15 seconds. The green
DISARMED light on the Controller Unit display panel will flash for all the Detonator Units
that the Controller Unit does not receive a status message from.
5.5.7.
Select the Detonator Units that are to be used in the shot by pressing the
corresponding numbered switches “1” through “8”. Press the numbered switches one at
a time.
