inputs I1 through I5 and outputs I7 through I13 (see Table T6-2).
Terminals G7 and G8 are always used for DS and Q2
functions, respectively, and cannot be adjusted. Depending
on the type of switch and features ordered, Terminals G1
through G5 as well as G9 through G13 may not be available
The MX350 microcontroller is a modular control and monitoring
• Flexible control and communication options to suit any low-
voltage transfer switch application.
• Small footprint.
• Modular design, which reduces the number of spare
components for maintenance and testing.
• Integrated pushbuttons and LED indicators which reduce
required external components and wiring
• Multiple communication protocols which permit simple
integration into monitoring and control systems.
• A graphical control panel that provides local control and
access to system information.
Detailed technical information on the MX350 controller is
described in the manual Entelli Switch 350 Automatic Transfer
Control System (Publication Number 1601-9071-A1).

The MX350 Graphical Display
and Keypad
The MX350 controller features a ¼ VGA color graphical
display with status LEDs, an USB programming port
and menu-driven soft keys (see Figure Figure S6-16)
as well as dedicated control and navigational keys.
The header bar displays the hierarchical path name, the
date and time and the current password access level. The
soft-key labels are indicated on the bottom line. Soft-
keys are used for navigation, performing functions and for
acknowledgement transactions. Soft-keys labels change
to show relevant selections for the displayed screen. The
color of each soft-key label indicates its functionality. Soft-
keys are highlighted for the displayed page, unauthorized
keys are "greyed-out", and unused keys are not displayed.

The control panel LEDs summarize the status of the
transfer switch, including the following indications:
• ALARM: indicates that there is a problem with the ATS or
that a user con gurable alarm condition is active.
• TD DELAY: indicates that the controller is timing before
taking the next control action.
• XFER INHIBIT: indicates that the controller will not
automatically transfer to the other source and that operator
intervention is required to allow transfer.
• S1 (Source 1) Available LED: indicates that S1 power is
present and within user de ned limits.
• S2 (Source 2) Available LED: indicates that S2 power is
present and within user de ned limits.
• S1 (Source 1) Status LED: indicates that the load is
connected to S1 power.
• S2 (Source 2) Status LED: indicates that the load is
connected to S2 power.
