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).
