Schneider Electric 4000 ANALOG INPUTS

April 2001 Analog Inputs

Depending on the I/O modulesyou select, the circuit monitor can accept

either voltageor current signals through its analoginputs. See Table5–1on

page 70 fora list of I/O options. The circuit monitor storesa minimum and a

maximum valuefor each analog input.

For technicalspecifications and instructions on installing I/O modules,refer

to the instructionbulletin that ships with the I/O (see Table1–2onpage3for

a list of thesepublications). To set up analoginputs, you must first set it up

from the display.From the main menu, select Setup> I/O, then select the

appropriate analoginput option. For example, if you are usingthe IOX0404

option of the I/OExtender, select IOX-0404. Fordetailed instructions, see

“SettingUpI/Os”onpage 23 in Chapter 3—Operation. Then, in SMS define

the followingvalues for each analog input:

•Name—a16-character label used to identify the analog input.

•Units—the unitsof the monitored analog value (for example,“psi”).

•Scale factor—multipliesthe units by this value (such as tenthsor

hundreths).

•Report Range Lower Limit—thevalue the circuit monitor reports when

the input reachesa minimum value. When the input current is below the

lowest validreading, the circuit monitor reports the lower limit.

•Report Range Upper Limit—thevalue the circuit monitor reports when

the input reachesthe maximum value. When the input current is above

highest validreading, the circuit monitor reports the upper limit.
