TYPE 06—Synchronous Wired

For a list of Type 06 clocks, see the chart on the first page of this appendix.

The clock run motor receives 120Vac continuously, with 120Vac furnished to the clock correction coil for 55 seconds each hour from HH:58:05 to HH:59:00 to cause hourly corrections. Ten 120Vac signals are furnished to the clock correction coil (each for 95 seconds) beginning at 5:05:00, 5:07:00, 5:09:00, 5:11:00, 5:13:00, 5:15:00, 5:17:00, 5:19:00, 5:21:00 and 5:23:00 to cause the 12-hour correction. The final 12-hour signal ends at 5:24:35 (before the 5:30 lockout).
