Model 5601ACO2 Automatic Changeover Unit
TECHNICAL DESCRIPTION Revision 1.2 Page 4-3
Multiple changeover events, separated by more than approximately half a second are considered valid
conditions for ACO operation. This is the recommended operating mode because it offers normal
operation while minimizing system impact in the event of an output short.
4.2.3. Unlimited Change Mode
If you want to change when a valid switch criterion is met, then use the "Unlimited Change Mode."
