Description
Powerblast 30 Shot Electronic Permitted Type Initiating Machine with in
built Circuity Continuity / Resistance Tester and pre-firing cut off with high
resistance firing protection system with external re-chargeable battery,
with charger, key and Carrying Case Model PB-30
(suitable for Under ground Coal Mines of Degree I, II & III Seams)
Features:
- Powerblast Exploder will not charge if the connected circuit has higher resistance then recommended, or the circuit is open
- Powerblast Exploder does not fire till the rated output is attained, when the firing switch is pressed
- Powerblast Exploder is provided with low battery indicator which gives warning that the battery is low and gets internally locked till the battery is replaced or charged
- Powerblast Exploder will discharged internally If the firing is to be cancelled by turning the operating key to the “OFF” position
- Powerblast Exploder Is very compact and has high impact plastic moulded body
Powerblast Exploder is very simple to operate:
- First check the instrument by inserting the key and turning it clockwise for the condition of the battery.”L” indicates low battery and dot (.) indicates that the exploder is ” ON “
- Connect the external circuit leads to the exploder output terminals
- By turning the inserted key clockwise the letter “C” will appear on the dial indicating that the circuit is In order
- Keep the key in clockwise position until the letter “F” start flashing
- Press firing switch to explode
Instruction for Use:
- Insert operating key and turn clockwise to 60, the Exploder will indicate “C” & then “F” starts flashing when full charge is attained. Press firing switch to explode
- Replace OR charge battery for 16 hours continuously when low battery indicator starts flashing
Checking:
- The capacity of the Exploder may be tested by special power blast Exploder tester.
- We are majorly looking queries from Africa, Australia and America.
