MODEL: CB2 CB2 SPECIFICATIONS ES-2630 Rev.6 Page 5/7 http://www.m-system.co.jp/ OPERATION ■ CB2 Used Independently In normal operating mode, the CB2 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. ■ CB2 Used in Combination with ST/STL In normal operating mode, the CB2 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-DOWN buttons, 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. Span Adj. Zero Adj. Ramp Rate (response) Adj. COMMAND TERM.
