Appendix A

Local Control vs. Remote Control

The ACS 400 can be controlled from two remote control locations or from the control panel. Figure
65 below shows the ACS 400 control locations.
The selection between local control (LOC) and remote control (REM) can be done by pushing the
MENU and ENTER buttons simultaneously when ACS100-PAN is used, and by pushing the LOC/
REM button when ACS-PAN is used.

Local Control

The control commands are given explicitly from the control panel when the ACS 400 is in local
control.
