4.3.1Setting the 12VDC/24VDC Analog Power Jumper

The analog power jumper sets the common voltage that is applied to all of the analog input connec- tions. 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:

Analog power jumper

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

1-2 TOP

24VDC or 12VDC.

3-4 BOTTOM

3. Set the jumper as needed:

• Set the jumper to the 24VDC position by placing the black

COMMS

jumper on the middle and right pins.

4.3.2 Connecting the Analog Ground

Analog

Analog

The Universal Monitor features an analog ground

input

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

1-2 TOP

power from an external power source.

3-4

A two-wire transducer, which does not have an

external power source, does not need to be con-

nected to the analog ground.

TB10: COMMS

The analog ground connector has two terminals,

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.
