A maximum of 400 DigiShot
®
Plus 4G Detonators (dependent on down-line wire length) can be accommodated per
channel.
Due to the expanded non-volatile memory capacity of the new DigiShot
®
Plus 4G Detonator, the cable length is
now stored in the detonator during assembly. With this information stored in the detonator, the software on the
Control Equipment will automatically verify the cumulative detonator down-line length and warn the user should the
installation limits be exceeded.
The system can accommodate decking applications with up to six decks and three 4G detonators per deck while
using the Advanced and Planned Tagging Options.
DigiShot
®
Plus 4G detonators can be programmed from 0ms to a maximum delay of 20 000ms in 1ms increments.
Accuracy (Coefficient of Variance) is 0.01% up to 20 000ms
The following temperature limitations apply to the DigiShot
®
Plus 4G Detonator:
• -40°C to +80°C
• -40°F to +176°F
Store in a well-ventilated magazine suitably licensed for IMCO Class 1.1B or 1.4S (specified on packaging) and in
