Hardware wiring selection
With parameter SYS-01, the selection can be made for the wiring in the electrical cabinet, as shown in next figure. Wiring diagrams for two stage fan applications.
SYS-01 = 0; serial SYS-01 = 1; parallel
The different fan commands, according the "FanStageCmd" (FSC) and the serial/ parallel contacts, defined by SYS-01, are listed in the next table:
FanStageCmd (FSC) |
Fan outputs SYS-01 = 0 |
Fan outputs SYS-01 = 1 |
0 = off |
Stage1Cmd = off Stage2Cmd = off |
Stage1Cmd = off Stage2Cmd = off |
1 = low |
Stage1Cmd = on Stage2Cmd" = off |
Stage1Cmd = on Stage2Cmd = off |
2 = high |
Stage1Cmd = on Stage2Cmd = on |
Stage1Cmd = off Stage2Cmd = on |
