1678 RFD OPERATION MANUAL 45
System Safety Feature Once armed, the Remote Units must be sent a Fire
command within the Arm Time Period. If the Remote Units do not receive a Fire
command within the Arm Time Period, 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.
5.3.5. To arm the selected Remote Units, press the “ARM” switch. The red
ARMED light next to each selected Remote Unit switch will flash for approximately 5
seconds and then come on steady. The selected Remote Units are now ARMED!
5.3.6. To fire the Remote Units, press the “FIRE” switch and hold for 1 second.
The operator should get an indication of shot initiation. The ARMED light will go out
and the green SAFE light for each selected Remote Unit will come on steady on the
Controller display panel.
Note: When firing the RSTI with no tip or with a faulty tip, the green SAFE light for that
unit may not initially turn on following a FIRE operation. A subsequent press of the
“STATUS” switch illuminates the green SAFE light.
5.3.7. If not all the Remote Units were selected for the shot, repeat above steps to
initiate the remaining shots.
5.3.8. To disarm any Remote Units that have been armed, select the Remote
Units and press the “DISARM” switch. All selected Remote Units will disarm 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 SAFE light for that
Remote Unit on the Controller 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 SAFE light for that
Remote Unit on the Controller display panel. Under no conditions should the “FIRE”
switch be pressed as the Remote Unit is approached. DO NOT bring the Controller
closer than 100 feet (30 meters) to blasting caps, wires connected to blasting caps, or
other explosives.
5.3.9. Turn off the Controller.
5.3.10. Recover the fielded Remote Units.
5.3.11. Refer to Post Operational Procedures in chapter 5.5.14.
