Operation
Free Running Clock Operation
The Digital Clock/Timer can be used as a free running clock. No additional connections are required. It will run as a line syn-
chronous clock once time has been set.
Synchronous Secondary Clock Operation
The Digital Clock/Timer can be used as a correctable synchronous secondary clock. Simply connect it to a 3- wire
synchronous master clock system. For secondary clock wiring see diagram in Appendix 1. It will run free between corrections
synchronized to the AC power line. The Digital Clock/Timer should not be used in the 24 hour format mode if it is connected
to a 3- wire synchronous system, since the 12 hour corrections cannot distinguish AM and PM.
