1678 RFD OPERATION MANUAL x
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.
WARNING
Ensure that blasting caps are not connected to any of the Remote
Units during bench testing.
WARNING
This is a sensitive electronic radio system and it may be damaged.
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.
WARNING
Do not engage in RFD communications with the Remote Units when
they are connected to explosive charges until the shot is prepared and all personnel are
clear. The Remote Unit complies with the Recommended Table of Distances
established by the Institute for the Makers of Explosives (IME) when placed 25 feet (8
meters) or more from blasting caps or wires leading to them. For further information,
refer to the Institute for the Makers of Explosives Publication no. 20, Part II, Section (1).
WARNING
Do not touch the Shock Tube Tip Jacks on the top of the Remote
Shock Tube Initiator (RSTI) when armed or firing. Lethal voltages may be present.
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.
CAUTION All units must be thoroughly tested and the batteries fully charged prior
to operational use.
CAUTION Unequal air pressure inside the Controller may affect the operation of
membrane switch keypad. Extreme pressure differentials may irreversibly damage the
keypad and/or cases.
CAUTION Vents in all units should be momentarily opened and closed
immediately before use.
