3.4.3 Switch Settings (MBS Arrangement Only)
Switch "S2" on the Options Control Board (refer to
Figure 6
) is a four position "DIP" switch
that has four small rocker switches. Pushing on the top half of each switch section closes
the switch and turns it ON, pushing on the lower half turns the switch OFF. There are
labels on the board to help identify the switch section.
The first section "PLT" enables "Power Loss Trip" (or Manual Restart), and should be OFF
unless you want the Bypass and Inverter Output Breakers to trip on loss of power.
The second section "NCR" enables the Normally Closed REPO input and should be OFF
unless there is a normally closed REPO switch connected.
The third section "OTT" is not implemented and should be turned OFF to avoid confusion.
The fourth section is not used and should be turned OFF to avoid confusion.
