The ZK I is a mechanical six-place period delay mechanism whose electromagnet ope-rates at 8 to 12 volts and 0.2 ampere. The time for the completion of one step-up cycle after actuation is approximately 40 seconds. The ZK I was developed for the M 1 mine unit and was replaced by the improved ZK II. |
