5.4.3. Press the “STATUS” switch. The Controller Unit will request status from all
Remote 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 Remote Units that
the Controller Unit does not receive a status message from.
5.4.4. Select the Remote 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.
System Safety Feature Once armed, the Remote Units must be sent a Fire
command within 60 seconds. If the Remote 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.
5.4.5. To arm the selected Remote Units, press the “ARM” switch. The red ARMED
light next to each selected Remote Unit switch will flash for 10 seconds, then come on
steady for two seconds, and then continue to flash. The selected Remote Units are now
assumed to be ARMED!
5.4.6. To fire the Remote 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 Remote Unit will flash on the Controller Unit display panel.
5.4.7. If not all the Remote Units were selected for the shot, repeat above steps to
initiate the remaining shots.
5.4.8. To disarm any Remote Units that have been armed, select the Remote Units
and press the “DISARM” switch. All selected Remote Units will return to the
DISARMED mode in approximately 3 seconds.
CAUTION Do not assume the Disarm command has been received by the Remote
Unit unless DISARMED status is confirmed with a steady DISARMED light for that
Remote Unit on the Controller Unit display panel. If distance appears to be the
problem, move closer to the Remote Unit following standard procedures for this type of
situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedly as the
Remote Unit is approached. Maintain a safe distance from the Remote Unit. Do not
approach the Remote Unit until DISARMED status is confirmed with a steady
DISARMED light for that Remote Unit on the Controller Unit display panel. Under no
conditions should the “FIRE” switch be pressed as the Remote Unit is approached. DO
NOT bring the Controller Unit closer than 100 feet to blasting caps, wires connected to
blasting caps, or other explosives.
5.4.9. Turn off the Controller Unit.
5.4.10. Recover the fielded Remote Units.
