3. Misfired Detonator: Damage on part of PCB
① Symptom
Damage on power unit or communication unit.
A) Try communication again to display NC.
B) If only the communication & response unit is damaged, it is available to fire again.
② Symptom
Damage on firing unit
A) If trying to communicate again, communication is possible, but it is not available to fire.
※
Resolution: If possible, disconnect the wire to try firing again with 0ms.
If it does not fire, take action to return.
1. How to handle misfire
①
Check the location of misfired hole and check if detonation lead is visible.
②
Peel off the sheath at the end of detonation lead to implement ID Check by using Logger and Planner
(Available for ID Check with Logger only).
③
To communicate or fire again, use the auxiliary bus to connect the detonation lead in the misfired hole to
the main bus.
④
If ID has been checked with ID Check, input ID and delay time manually in the Planner to try the blast again
⑤
If ID is unknown, input temporary ID and delay time 0ms in the Logger to try the blast again. At this time,
entered arbitrary ID is displayed as NC and one shot of global detonator shall be confirmed. The global
delay time shall be entered in the detonator to fire.
