Program a relay No. from “0” to “n”. The example is for programming to “3”. Program “0” if no output is necessary.
The programming after this step or before the alarm type selection, refer to the flow chart in Section 11.5. 4 2).
FAiL, C. End
The total numbers of alarm points are number of channels x number of levels (4) + 2 (FAiL and C. End). Number of output points is 6 or 12 points. (RD200: 6 points only)
Place the cursor to the column of channel in
“Selecting alarm type” and press | / | until |
“FaiL” or “C. End” is displayed. In this condition, select a relay No. to output when the corresponding phenomenon occurs.
