7.2.6 Units with a Automatic Transfer Switch (ATS)
Fig. 7-1
The Automatic Transfer Switch (ATS) allows for 2 mains power supplies to be con-
nected with the Multi-DENCO unit. In the event of a power failure, the switch will switch
from the "Primary" power supply to the "Secondary" power supply. During this process,
the power supply to the unit is disconnected. The ATS has an inbuilt, adjustable timer
to set the time period before it can check and return to the "Primary" power supply.
A manual over-ride can be performed to choose the power supply by lifting the clear
plastic cover and using the Allen key provided. The clear plastic cover must be fully
closed to activate the automatic change-over function.
The DIP switches should be configured like the following:
