BlastPED III Operator Manual

Ohmmeter
When a BlastPED III has its Safety Switch turned to the ON position and has passed all
internal checks, an Ohmmeter will display the line resistance at the output terminals.
BlastPED III is designed to fire a series circuit up to 75 Ohms. Circuit resistance exceeding 75
Ohms may result in a misfire.
Security Media
Each BlastPED Receiver is provided with codes required by PEDcall to generate the ARM
and BLAST command for that unit. These codes can be provided on either Floppy Disk, CD-
ROM, or USB Memory Stick at owner’s request. Without these codes, PEDcall software is not
capable of generating the full commands.
The media containing these codes should be kept in a very secure location, used only when
creating blasting messages, and returned immediately after. Controlling access to these
codes is controlling access to who can initiate a blast.
Unique Site ID
Mine Site Technologies assigns a unique ID to
every location where BlastPED III is in use.
BlastPED III units are delivered with the
customers Site ID pre-programmed.
This ensures that BlastPED III units from one
location cannot mistakenly synchronize with the
signal from another locations PED system, and
in turn act upon ARM ALL and BLAST ALL
commands.
PEDcall software must be configured with the
Site ID. Configuring this is done in the Options
screen, in Blasting Settings, under Site Security.
