S4 Adjustable COR Lock (Voting Lock); Onset Delay Timer
The rotary switch S4 on the CPM-3 module is changed from a “Voting Delay” control to a
“Delay before COR Lock” whenever the COR Lock feature is enabled by CPM switch SW3-3.
See Sections 3.12.5.3 and 5.8 for further information about COR Lock. Note that the “Voting
Delay” adjustment is not needed when the COR LOCK feature is enabled, since the COR lock
prevents all voting transitions. (The COR Lock feature is also called “Voting Lock.”)
The “standard” delay setting (position 0) means simply that the voter performs its normal
voting functions without regard to the SW4 setting. For the other positions, the voter will
ensure that the lock does not occur until the set delay elapses. The delay timer starts the
moment when the CPM is informed of an unsquelched SVM. The actual time between an
unsquelch condition and the onset of the COR Lock may take a longer (but not shorter) period
of time than the SW4 setting because of the polling operation of the SNV-12. The CPM
communicates with each SVM in turn, so the precise timing depends on a module‟s order in the
polling cycle and the number of SVMs in the system.
