Does somebody have the info on what mines they where used. The info below is what I know already.
Period delay mechanism (zahl kontakt)
All German periods delay mechanism are spring driven clockwork.
systems whose escapements are released by electromagnets. The mine firing unit must first be activated before the escapement electromagnet of the period delay mechanism can be energised.
The zkIIb is a mechanical 12 place delay. The electromagnet operates off the microphone battery at 3/4 volts and 0,5 amps.
