supply algorithm enables the Gold Whistle to operate with only one power supply with
no need for an auxiliary power supply for the logic.
Optional Backup (Auxiliary) Supply
If backup functionality is required in case of power loss, e.g., to keep the original
position, a 12–95 VDC external isolated supply should be connected (via the Gold
Whistle’s VL+ terminal). This is more flexible than the requirement for 24 VDC supply.
If backup is not needed, a single power supply is used for both the power and logic
circuits.
There are two voltage ratings of the Gold Whistle, therefore the correct power supply
must be used, according to the maximum operating voltage of the Gold Whistle. Refer
to Chapter 3: Technical Information.
