Introduction
The BlastPED III Receiver/Exploder is the newest generation of Mine Site Technologies’
BlastPED System. It enables remote, centralised blasting using a PED System.
BlastPED III has been developed to cut the high cost associated with maintaining the integrity
of underground blasting cables. By eliminating these cables, the costs of maintenance and
lost production due to misfires are reduced.
Like its predecessors, the BlastPED III system is designed with safety as the prime criteria. It
introduces additional layers of safety and improved design, while maintaining the simplicity of
use, and backwards compatibility with existing BlastPED models.
The BlastPED System has two main aspects of use:
1. Setup of the remote BlastPED Exploder
2. Sending of commands from the PEDcall software
Prior to implementing the BlastPED system, a mine must establish procedures for all aspects
of its correct safe use. A complete understanding of this document is essential when doing so.
WARNING: BlastPED must be used from a safe location only, and procedures developed for
use at each mine must take this into account.
WARNING: Any procedures shown in this document must be used in conjunction with the
mine’s site procedures, including but not limited to tagging and explosives handling.

BlastPED III Firing Overview
The following section describes the order of events when firing a BlastPED III unit.
Setup Exploder
The BlastPED exploder is set up in a safe position near the face to be fired and turned ON.
The firing line is then connected to the output terminals (see Section 3 for specific details).
The BlastPED III exploder will synchronise with the PED signal.
NOTE: Refer to Section 4: Setting up the BlastPED III at the face for more information.
ARM
The PEDCALL software operator inserts the appropriate Safety Media in the PC. The ARM
command is then transmitted. After ARM command is received, the BlastPED ARM LED will
light, a siren will sound, and the capacitor will commence charging.
After arming, the BlastPED III unit will remain armed for up to 10 minutes. The firing process
will be automatically aborted if blasting is not performed during this time (i.e. BLAST
command sent & received). If this occurs it will require another ARM command before
blasting can proceed.
NOTE: Refer to Section 5: Sending BlastPED III Messages for more information.
BLAST
The PEDCALL software operator sends the BLAST command to the unit which has been
armed. As the BLAST command is received by the armed unit the charged capacitor is
connected to the output terminals. The capacitor discharges into the firing line, initiating the
detonators.
Two (2) seconds after blasting the BlastPED III exploder automatically locks out and;
•The unit's output is isolated from the battery and firing capacitors
•Firing cables (connected to output terminals) and firing capacitor are short circuited
•Subsequent ARM and BLAST commands are ignored
•The red LED labelled BLASTED, shows that the unit has discharged and is now locked
out

NOTE: Refer to Section 5: Sending BlastPED III Messages for more information.
WARNING: A lethal voltage of up to 250 VDC is present across the output terminals when
firing occurs.
Retrieve and Secure Exploder
After blasting the BlastPED III remains locked and will not receive any subsequent messages.
The BlastPED exploder must be reset (key turned to SAFE, then to ON) before another firing
output can be produced.
Ensure that the BlastPED III unit is safely stored and recharged in preparation for next use.
NOTE: Refer to Section 6: BlastPED III Maintenance and Service for more information.

BlastPED III Safety Features
This section covers the safety elements engineered into the operation of a BlastPED III
system. Procedures for blasting should focus on and ensure their correct use.
Safety Switch
The face of a BlastPED III unit has a rotary two position switch with positions marked SAFE
and ON.
In the OFF position there will be no activity on the unit’s face panel. The BlastPED III is not
capable of receiving messages or opening the short circuits between the capacitor and firing
outputs.

While the BlastPED III provides protection at the output terminals all the way up until the
BLAST command, it is recommended that units have their switch in the SAFE position when
not being wired and set for use.
Two Message Blasting
The requirement for initiating a BlastPED III is receipt and verification of two separately
generated PED messages; ARM and BLAST. These messages will take a minimum of two
minutes each to transmit.
The state of the BlastPED III unit is defined as its ability to receive one of these two
messages. Feedback on which state the unit is in is provided on the face panel.
A unit displaying the Power LED and Receiving LED is in its ready state and capable of
receiving an ARM command.
A unit displaying the Power LED, Receiving LED, and Arming LED is in an armed state and
capable of receiving a BLAST command. In this case it will also be sounding its buzzer.
The ARM commands
An ARM command tells the BlastPED III unit that blasting is imminent. After receiving a valid
ARM command, a BlastPED III receiver will sound a warning buzzer and begin charging its
internal capacitor.
NOTE: An ARM command should not be sent until there is confirmation that all receivers are
set, and personnel have retired to a safe location.
An armed unit that does not receive a matching BLAST command within 10 minutes will
revert to a ready state, capable of receiving and acting upon another ARM command.
The BLAST Command
A BLAST command tells the BlastPED III to initiate the firing lines. Only after receiving a valid
ARM command is the unit capable of acting upon a matching BLAST command.
WARNING: Lethal voltages will be present at the output terminals when blasting.
After a completed blast the BlastPED III unit will show its Cycle Complete LED and is now
incapable of receiving or acting upon any commands until it is reset.

BlastPED III Operator Manual
13
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.
For further information on PEDcall Options refer
to the PEDcall documentation.

Setting up the BlastPED III at the Face
The following section describes the actions taken to set a BlastPED III Exploder at a working
face. If there is any doubt of a unit’s capacity or reliability it should not be used under any
conditions.
Check Blaster
Confirm that the BlastPED III unit has been charged and is suitable for use. Ensure the Safety
Switch is in the SAFE position.
Setup only in a Safe Position
The BlastPED Exploder should be set up in a safe position where it will not be hit by fly rock
or exposed to excessive concussion. The operator should place the Exploder:
•Out of line of sight of the face.
•In a position where the operator would be prepared to hand fire from.
•Within range of the PED system signal.
Turn on Blaster
Turn the Safety Switch to the ON position. The SERVICE LED will flash and after
approximately 10 seconds the Ohmmeter Liquid Crystal Display (LCD) will be activated. After
another 10 seconds, the green ON LED should light, indicating the unit has self-tested, and is
ready for use.
If the PED signal is present, after 2 to 5 minutes the RECEIVING LED will come on indicating
the system is ready for remote signalling (i.e. it has synchronised with the PED signal).
If the BlastPED III fails any internal checks it will turn off the Ohmmeter and POWER LEDs
and display the blue SERVICE LED. If the SERVICE LED is flashing the unit has detected a
timing error and may be resettable by cycling power. If the SERVICE LED is solid, then the
unit has detected a hardware error and must be Tagged Out. A BlastPED III unit with a solid
SERVICE LED will not operate until it has been serviced by a Mine Site Technologies
technician.
Connect Cables
Ensure the firing lines are not near any radios if these are in use at the mine. Connect the
firing cables to the output terminals.

BlastPED III Operator Manual

The circuit must be a pure (simple) series circuit. The use of Parallel, Series-in-Parallel, or
Parallel-in-Series can result in a misfire. Using a series circuit is relatively straight forward
with a single face, but if firing two or more faces from one BlastPED then care must be taken
to ensure all the faces are wired in a simple series circuit.
The Line Resistance is continuously shown in ohms on the LCD. It should read less than the
rated 75 ohms, and if more, the circuit should be checked.
The unit is now ready to receive PED commands through the PED System.
NOTE: Before leaving the site; both GREEN LEDs must be on, which indicates that the unit is
ready for firing.
After firing, the firing cables should be shorted (twitched) and removed. The Safety Switch
should be returned to the SAFE position. If the unit has not fired, twitch and disconnect firing
lines, turn the Switch to SAFE, and report the event.

Sending BlastPED III Messages
Creating the ARM and BLAST commands is done using PEDcall for Windows Version 6 or
later. Please refer to the PEDcall documentation and help files for more information including
software setup.
The Blasting Message Panel
BlastPED commands are accessed from a dedicated blast message panel. This can be
opened by clicking on the BlastPED icon in the main application toolbar.
Blasting can be carried out in one of three ways;
as Individuals, in Groups, or All BlastPEDs fired
at the same time. A unit armed in one way cannot
be blasted using another. To create multiple ARM
and BLAST messages without opening the
message panel each time, check the Remain
open after selection box that is located bottom
left.
To exit the blast message panel without creating
a message either click on the Close button or
press ESC.
Understanding Blasting Messages
Blasting messages are handled differently to other PED messages. Operators should be
aware of these differences before being authorised to create ARM and BLAST commands.

BlastPED III Operator Manual
18
Message Priority
All blasting messages take priority over any other PED messages except other blasting
messages. Blasting messages cannot be moved up or down in the Message Queue, they are
sent in the order created.
Deleting Messages
Blasting messages can be deleted from the Message Queue the same way normal messages
are. If both ARM and BLAST pair are in the Message Queue, then deleting one will
automatically delete the other.
All pending blasting messages are deleted from the queue when PEDcall is shut down. Due
to an internal session ID it is not possible for PEDcall to send blasting messages that it didn’t
created since startup, hence any blasting messages found in the queue at startup are
deleted.
Creation Restrictions
PEDcall must be connected directly to a
responding PED Modulator before it will allow
creation of any blasting message.
PEDcall will not allow the operator to create a
BLAST command before first creating an
appropriate ARM command.
Additionally, there are two options configurable
in PEDcall that further restrict blasting
messages.
If Single Blast Commands is checked then
PEDcall will require that the ARM command is
sent before allowing creation of the associated
BLAST command.
If the 10-minute start-up lock is checked then PEDcall will not allow creation of any blasting
commands until 10 minutes after establishing a link with the PED Modulator. This option is
useful if the PED system is only turned on for blasting - it ensures that the PED signal has
been generated long enough for units to synchronise before messages are sent.

BlastPED III Operator Manual
19
Security Media
Part of the code to create an ARM and BLAST command is provided on removable storage
media that can be secured to prevent accidental or unauthorized blasting message creation.
Appropriate codes are included with each BlastPED III delivered. Contact Mine Site
Technologies for more information on how to obtain replacements.
The codes for each method of blasting: single, group, and all BlastPEDs are separate.
Providing the wrong code when attempting to generate a blasting message will produce an
error.
Creating Blasting Messages
The following is a step by step guide to creating blasting messages using PEDcall for
Windows Version 6.
Confirm all BlastPED III Exploders are setup and
ready for blasting. Confirm which blasters will be
addressed: Individual, group, or all. Confirm all
personnel are in a safe location and aware a blast
is pending.
Retrieve Security Media from its safe location.
Remove only the type of media needed for the
blasters that will be addressed.
Click the “BlastPED” button on the PEDcall Main
Menu to bring up the Blasting Message Panel.
Select appropriate address if required; from the
drop-down box for groups, or the scroll list for
individual.
Click on the ARM button appropriate to the units being blasted.

At the Security Request prompt, connect or insert
the Security Media to one of the configured
locations as requested.
The Security Media must be present in exactly one
of the configured locations. If a duplicate is found, it
will be rejected.
Upon successful verification of the Security Media,
the message “Media verified” will be displayed and
Ready button will become enabled.
Press Ready to create an ARM message and add it to the PED Message Queue. It will be
sent at the earliest opportunity.
To progress, if the Blasting Message Panel is not open, click again on the “BlastPED” toolbar
icon to open it.
Click on the BLAST button appropriate to the units being blasted.
Insert the security media in one of the configured locations and click Ready to proceed when
Media is verified.
A BLAST message is created on the PED Message Queue and will be sent at the earliest
opportunity.
