MXCB Used Independently
In normal operating mode, the MXCB responds to UP/DOWN signals
from the computer in the preset ramp rate. If the computer fails, this will
be detected as a “STOP” command and output will be held at the value
prior to the breakdown. You can increase the output signal by closing
across the terminals 9 – 11, and decrease it by closing 10 – 11. The output
responds in the preset ramp rate.

MXCB Used in Combination with ST/STL
In normal operating mode, the MXCB responds to UP/DOWN signals
from the computer in the preset ramp rate. If the computer fails, the
“STOP” command will override computer output and put the unit in the
manual operation mode by the ST/STL. Using the top-mounted UP or
DOWN key, output can be increased or decreased in the preset ramp rate.
Output signal value can be read on the top-mounted indicator.
For more precise control, use the monitor terminals. Also the computer
input can be overridden with the AUTO/MANUAL selector on the
Soft-Terminal. This is useful when you need to change the output quickly
during automatic operation by the computer control.
