4.3.1 Setting the 12VDC/24VDC Analog Power Jumper
The analog power jumper sets the common voltage that is applied to all of the analog input
connections. The jumper permits the user to modify the voltage supplied to the sensors, according to
the power requirements.
The factory default position is 24VDC; it may be changed to 12VDC.
To change the analog power jumper setting:
1. Find the black analog jumper on the circuit board, as shown at
right. The jumper is at the bottom of the board near the middle
(see 1.7 - Controller Board Overview).
2. Decide whether your configuration requires the jumper to be
24VDC or 12VDC.
3. Set the jumper as needed:
• Set the jumper to the 24VDC position by placing the black
jumper on the middle and right pins.
• Set the jumper to the 12VDC position by placing the black
jumper on the middle and left pins.
4.3.2 Connecting the Analog Ground
The Liebert Universal Monitor features an analog
ground connection for four-wire sensors that have
an external power source. Such a four-wire sensor
requires a reference to ground because they get
power from an external power source.
A two-wire transducer, which does not have an
external power source, does not need to be
connected to the analog ground.
The analog ground connector has two terminals,
each of which can accommodate two wires. This is
adequate to connect four sensors that require a
reference to ground because they get power from
an external power source.
Connect the analog ground to an external four-
wire sensor as shown in the illustration at right.
