1678 RFD OPERATION MANUAL 43
WARNING
Do not use the Controller within 100 feet (30 meters) of explosives,
blasting caps, or wires leading to them. The Controller signal is 5 watts, which can
cause detonation of caps if within 100 feet. The 5 watt Controller complies with the
Recommended Table of Distances established by the Institute for the Makers of
Explosives (IME) when placed beyond 100 feet of explosives.
5.1.5. Turn the Controller on by pressing the “ON” switch for 1 second. A yellow
light located in the upper left quadrant of the Mini Controller’s “ON” switch will turn on
steady. The “BAT” yellow light at the top of the Controller Unit’s display panel will turn
on. If the yellow light does not turn on steady, but flashes, this indicates a low battery
for the Controller. Recharge the battery in accordance with Section 4.2.
5.1.6. Adjust the intensity of the LED display on the Controller for the desired
setting by repressing the ‘ON’ switch on the Controller.
5.1.7. Press the “STATUS” switch on the Controller. The red TX light will flash for
approximately 5 seconds. The green SAFE light corresponding to each Remote Unit
will come on steady if the Controller receives a status message from that Remote Unit.
If the Controller does not receive a status message from a Remote Unit, the green
SAFE light for that Remote Unit will flash on the Controller display panel.
Note:
The Controller battery life is approximately 6 hours when in the “ON” condition.
To conserve battery life, the Controller should be turned off when not being used.
5.1.8. Turn the Controller “OFF” until Remote Units are in place and wired to
shoot.
5.2. PLACEMENT OF REMOTE UNITS
WARNING
Do not connect a blasting cap to a Remote Unit unless the green
SAFE light is on, the red ARMED light is off, and the yellow ON/LOW BATT light is on
steady. This indicates there is no voltage on the binding posts, the binding posts are
electically isolated from the firing capacitor, the binding posts are shunted to each other,
and the battery is not low.
5.2.1. The range of the RFD is typically 5 miles under most conditions.
5.2.2. Place the Remote Units with the antenna in a vertical position and free from
obstruction within 100 feet (30 meters) of the shot. Use sandbags or other suitable
materials to protect the Remote Units from the shot.
5.2.3. Ensure that all Remote Units indicate a SAFE condition (green SAFE light
on steady).
5.2.4. If using the RSTI, proceed to Section 5.2.7. After performing standard
demolition circuit checks and before placing initiator into the main charge, depress the
two spring-loaded binding posts on the Electric Remote Unit.
