Legrand PDU User Guide 135
To select multiple actuators, click
to make checkboxes appear and then select desired
actuators.
2. Click the desired button.
: Turn ON.
: Turn OFF.
Note: Per default you can turn on as many dry contact actuators as you want, but only one "powered dry
contact" actuator can be turned on at the same time. To change this limitation of "powered dry contact"
actuators, modify the active powered dry contact setting. See
Peripherals
(on page 130).
3. Confirm the operation when prompted.
Tip: If intending to control the actuator via the front panel, see
Front Panel Settings
(on page 247).
Yellow- or Red-Highlighted Sensors
The Legrand PDU highlights those sensors that enter the abnormal state with a yellow or red color. Note that
numeric sensors can change colors only after you have enabled their thresholds.
Tip: When an actuator is turned ON, it is also highlighted in red for drawing attention.
For concepts of thresholds, deassertion hysteresis and assertion timeout, see
Sensor Threshold Settings
(on page 509).
In the following table, "R" represents any numeric sensor's reading. The symbol <= means "smaller than" or
"equal to."
