Optional Color Touch-Screen Interface
Standard LED Panel
The controls of the HiSwitch2 are intuitive and simple. The
pop-up menus are easy to understand and provide a wealth
of operational and diagnostic information.
This optional color LCD monitor is divided into three segments.
In addition to a system mimic diagram, there is a Status/Alarm
panel and a section dedicated to operator instructions and
menus. You benefit from improved operator effectiveness,
reduced training time, and less chance of operator error.
In case you need simplified version of interface, the
Standard LED Panel is a good and economic solution for the
customer. It is possible to monitor the unit and alert when a
problem occurs by means of a series of LEDs and buttons.
Both optional and standard Panel solutions can be accessed
from a terminal, or a PC running terminal emulation soft-
ware, that is attached to the unit.
