Local Control vs. Remote Control
The ACS 140 can be controlled from two remote control locations or from the
control panel. Figure 17 below shows the ACS 140 control locations.
The selection between local control (LOC) and remote control (REM) can be
done by pushing the MENU and ENTER buttons simultaneously.

The control commands are given explicitly from the control panel when the
ACS 140 is in local control. This is indicated by LOC on the control panel
display.
