Signaling in parallel
operation
System availability is additionally increased if two power supply units are connected in
parallel for redundancy reasons. Remote monitoring is recommended for each power
supply unit in order to immediately detect a device failure and to keep the redundancy at
any point of time.
Multiple power supply units can either be monitored individually or using a common signal.
As shown in Figure 3-15 a loop connects the active switching output of the first device and
the electrically isolated contacts of further devices.
For function monitoring the signal output is isolated from the power output. "Reverse
supply" by a power supply unit to the "DC OK" output of the power supply units connected
in parallel is not possible. A clear function signal is generated at any point of time.
