Anderson Manufacturing AV-9000 manual Shipped CONFIGURATION/JUMPER Positioning

2.3.1 SHIPPED CONFIGURATION/JUMPER POSITIONING

Each instrument is factory shipped with all parameters set to default values. These defaults are shown in the "display" box for each parameter in Section 4.

Jumpers are used to condition the sensor inputs. All jumpers are located on the Input Board(s). The instrument is shipped from the factory with these jumpers configured as follows:

JU1	IF FITTED	UPSCALE BREAK
JU2		Non-Contact Closure Input
JU3		T/C, mV, 0/1V, Switch, mA
JU4	IF FITTED	UPSCALE BREAK
JU5		Non-Contact Closure Input
JU6		T/C, mV, 0/1V, Switch, mA
JU7		WIDE SPAN
JU8		WIDE SPAN
JU11	IF FITTED	Non-RTD
JU12	IF FITTED	Non-RTD
JU15		Non-mA
JU16		Non-mA

There are 2 additional jumpers per Input Board that are used for ID. These must be positioned as shown in Table 2-1 below as per their location inside the instrument. Board 1 is the bottom board.

TABLE 2-1 BOARD ID JUMPERS

	Inputs	Inputs
	1, 3, 5, 7	2, 4, 6, 8
Board Position	JU13	JU14
Board 1

Board 2

Board 3

Board 4

If any board is removed from the instrument in a multiple stack of boards, it MUST BE installed in the correct sequence or these jumpers MUST BE moved. If not installed correctly, calibration will be affected.

2.3.2 SENSOR BREAK and OUT-OF-RANGE DETECTION

Sensor break and out-of-range conditions are determined and handled by the software. When either occurs, the software will drive the input value to +99999 or -99999 based upon whether SENSOR BREAK is software config- ured for UPSCALE or DOWN SCALE in Input Configuration. Any outputs will react accordingly. Out-of-range is defined as being more than 5% out of the span established by RANGE LIMIT LOW and RANGE LIMIT HIGH.

For 5 or 10 Volt and Current inputs, the analog signal goes to zero when there is a sensor break, due to voltage divider or shunt resistors. For sensor break detection to work on these input types, the INPUT RANGE LOW (analog signal low) and/or RANGE LIMIT LOW (engineering units low) parameters must be set high enough such that at zero volts/mA, the resultant value will be at least 5% below the span established by RANGE LIMIT LOW and RANGE LIMIT HIGH.
