5. OPERATIONAL PROCEDURES
WARNING
Use of this system and its components must be restricted to personnel
qualified and experienced in the field of explosives and detonating devices. Under no
circumstances shall untrained personnel attempt to use this manual as a text for self-
teaching.
WARNING
Employ standard blasting system safety standards when using this
equipment with explosives.
WARNING
All units must be thoroughly tested and the batteries fully charged prior
to operational use.
5.1. READY THE SYSTEM AT SITE
5.1.1. Remote Units. Select the number of Electric Remote Units or RSTIs
required for the operation. Remove the dust cover from the antenna / battery charger
connector. Install the Antenna Assembly on to the antenna / battery charger
connector. This will turn on the Remote Unit. The yellow ON/LOW BATT light and
green SAFE light will be turned on. The green SAFE light will be on for the first
minute, whenever the Remote Unit is turned on and it is disarmed. In the disarmed
state, the firing capacitor charge circuit is disabled, the firing terminals are electrically
isolated from the firing capacitor, and the firing terminals are shunted to each other. If
the yellow ON/LOW BATT light is flashing, the Remote Unit battery is low and should
be recharged before use.
5.1.2. Remote Sleep Mode. If Sleep Mode is enabled, after 1 minute, the display
lights on the Remote Units will extinguish. During this time, the Remote unit is in a low
power ‘sleep’ state to conserve battery power. Sleep Mode can only be entered if the
Remote Unit is disarmed. The Remote units are quickly awakened by the Controller’s
radio signal when needed for use.
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.
5.1.3. Open and close the vent on each Remote Unit and the Controller to
equalize the case pressure. Unscrew the vent, one revolution, to open.
5.1.4. Remove the dust cover from the antenna / battery charger connector of the
Controller. Install the Antenna Assembly on to the antenna / battery charger
connector. This will enable the keypad on the Controller.
