7.2 Teaching Sensors
NOTICE
The internal temperature sensors installed in the unit (exhaust air sensors) are supplied already taught. The
internal sensors therefore do NOT have to be taught during commissioning.
Optional sensors can be connected to the RJ45 connector of the Vertiv™ Liebert® DCDactive. The sensors communicate with
the Liebert® DCDactive via a OneWire bus. To use the sensors, they must be taught during commissioning. Temperature
sensors and OneWire adapters for door contact switches and leak sensors can be taught-in. Since the various sensors work
according to the same principle, the procedure for teaching-in is also identical.
The sensors within the Liebert® DCDactive also work according to the same principle. For repair purposes, the service
technician can also teach these sensors via the Set-up menu.
NOTICE
When teaching-in a sensor, only one sensor may be connected at a time. Otherwise the teaching process will fail.
Since the sensor circuits of the server cabinet sensors and the internal sensors in the Vertiv™ Liebert®
DCD35/50 Active are separate, this only applies to the affected sensor circuit in each case.
Once a sensor has been correctly taught, it is stored by the Liebert® DCD35/50 Active. As soon as an already
taught sensor is connected, it is evaluated by the unit. It takes up to maximum of 30 seconds to recognize the
connection of a new sensor. In order to teach several sensors one after the other, a sensor that has already been
taught can be disconnected without hesitation and reconnected later. A sensor which has already been taught
can be disconnected from the unit for approx. one minute before an error message is generated.
NOTE: A sensor that has already been taught-in cannot be taught-in again under a different sensor number or a
different function. It must first be deleted from the number or function you no longer want. Furthermore, the type of
sensor must match the function (i.e., a OneWire adapter cannot be taught as a temperature sensor).
NOTICE
Since the temperature sensors and OneWire adapters are externally very similar, it is recommended that the
sensors are first taught individually directly at the unit's RJ45 connection and then marked with the sensor
number or function (door contact or leak). The sensors can then be installed and connected in the server
cabinet.
To teach a temperature sensor, the following steps must be carried out in the specified order. The teaching procedure is the
same for both sensor circuits and is therefore described here using screen examples for the server cabinet sensors.
• On the affected sensor circuit, all but the one sensor to be taught must be disconnected.
