BI1 to BI6 correspond to each binary input signal. For thebinary input signal, see Appendix B and G. The status is expressed with logical level "1" or "0" atthe photo-coupler output circuit. BI3 to BI6 are not available for model 400 and 420.Line 2 shows the binary output status. All binary outputs BO1 to BO4 and FAIL are configurable.The status of these outputs is expressed with logical level "1" or "0" at the input circuit of the outputrelay driver. That is, the output relay is energised when the status is "1".FAIL is a normally closed contact for detection of a relay fail condition.Line 3 shows the binary output status for model 402 or 422. BO5-8 (OP2) are available only atmodel 402 or 422.4.2.4.3 Displaying the Status of Measuring ElementsTo display the status of measuring elements on the LCD, do the following:• Select "Status" on the top "MAIN MENU" screen to display the "Status" screen.• Select 3 "Ry element" to display the status of the relay elements./ 2 R y e l e m e n tA O C 1 - 4 [ 0 0 0 0 ]B O C 1 - 4 [ 0 0 0 0 ]C O C 1 - 4 [ 0 0 0 0 ]E F 1 - 4 [ 0 0 0 0 ] Not available for model 820 and 821.S E 1 - 4 [ 0 0 0 0 ] Not available for model 400 series.A U C 1 ・ 2 [ 0 0 ]B U C 1 ・ 2 [ 0 0 ]C U C 1 ・ 2 [ 0 0 ]T H M [ 0 0 ] 96
