Motor Coach Software (Revision 4.01 Option 1)
Notes on Changes
The Motor Coach software for the Trace Engineering SW series Inverter/Charger has been specifically
developed to meet the operational requirements of vehicle applications. The new software includes
several changes to the inverter/charger’s basic operation in addition to changes to the default settings.
The Motor Coach version is an option for the new Revision 4.01 software, introduced in April of 1996 on
all of the SW series. It is available in 12 VDC and 24 VDC versions.
The changes can be divided into two groups - changes to the basic operation and changes to the default
settings. Both groups should be examined together with the changes made in the new Rev. 4.01 software
compared to the previous Rev. 3.0 software. Some additional user programming of the inverter and
charger settings may be required for your application.
Important Revision 4.01 Changes
The new Rev 4.01 software includes many improvements and new abilities. The most substantial
changes for Motor Coach applications are summarized here. A copy of the new Revision 4.01 manual
should be reviewed for more information on these and other changes.
•
Menu System - The new Rev 4.01 software divides the menu system into two parts - a USER menu
and a SETUP menu. This simplifies the menu system for the system user and reduces problems with
accidental changes to the inverter/charger settings.
•
Generator Start System - The new Rev 4.01 software now includes two different start routines. The
system itself has been made more fault tolerant and has additional error indications.
•
Control Panel Operation - The red and green buttons now also are able to select the desired setting
from the menu item displayed. The “action” of the buttons has been improved. The “reset to factory
default button” now can be used to reset the display. This button now only resets the default settings
from a specific menu item location.
Important Operational Changes for the Motor Coach Version
The Motor Coach version includes several changes in the basic operation of the inverter from the
standard operation of the Rev 3.0 and Rev 4.01 software previously shipped.
•
AC2 Priority - The AC2 input (generator) is now the priority. If the AC1 (grid) is energized from the
shore cord being plugged in, then it will be disconnected when the generator is started. The transfer
from shore cord to generator may take 8 seconds or more. (The terminal block on the inverter still
lists AC1 as the priority - the change was made in the software only for the Motor Coach version.)
•
No Cool Down - The Rev 4.01 software includes a cool-down period for the generator after it was
operated. This is not included in the Motor Coach software.

Important Default Setting Changes for the Motor Coach Version
The Motor Coach version includes several changes to the default setting of the Rev 4.01 software. Any
unnecessary menu headings have also been eliminated to reduce the complexity of the menu system.
•
Shore Cord Size - A new menu item, SET SHORE CORD AMPS AC, has been included in the
USER menu under the SET INVERTER (1) menu heading to allow adjustment of the SET GRID
(AC1) AMPS AC menu item in the SETUP menu. This makes it easier for the user to change the
setting based on the hook-up capacity. It should be set to match the shore cord being used by the
coach user when connecting the coach to utility power.
•
Battery Charging - The software is programmed to have the default settings be appropriate with
sealed gel cell or AGM type batteries. The equalization system has been defeated.
•
Generator Starting - The software defaults to a new generator start routine designed for use with
Onan and many diesel generators. See the Rev 4.01 manual for more information. The warm-up
period for the generator has been reduced to 16 seconds. The exercising system has been disabled.
•
Low Battery Cut Out - The default settings have been changed to allow greater use of the batteries.
The LBCO setting is now also used by the generator start system to signal the generator to start if the
battery reaches the LBCO setting for 30 seconds continuously.
Identification and Compatibility
The Motor Coach version can be identified by checking for the REVISION 4.01 OPTION 1 menu item
display under the TRACE ENGINEERING (3) menu heading. This assures that the inverter includes the
new software.
The Motor Coach software is compatible with all SW series inverter/chargers built by Trace Engineering.
The software must be configured for the DC input and AC output voltage involved before the “chips” are
programmed. To change the software, the cover of the inverter must be removed and the top needs
good access. This may require removal of the inverter/charger from the vehicle.
Series II Inverter/Chargers
The Motor Coach version also includes changes to the inverter/charger itself. All currently manufactured
units now include:
•
Series II Chassis - A new chassis is being used on all SW series inverter/chargers. It features
improved AC wiring access and a easier to remove cover for upgrading software.
•
High Visibility Display - The LCD display now is backlit and has greater visibility from the sides and
below.
•
Larger AC Input Contactors - The relays which connect the generator or utility grid ac sources to the
inverter have been changed to a larger, heavier duty relay. This change has eliminated the problem
with stuck relays previously encountered.
AC Input Provisions and Ground Bonding
Neither the Motor Coach version or the standard version of the SW series inverter/charger includes
ground switching or bonding. This must be added externally to the inverter/charger.
DO NOT CONNECT BOTH THE GENERATOR AND THE UTILITY GRID TO THE SAME AC INPUT
TERMINALS - THIS IS NOT ACCEPTABLE A WILL VOID THE WARRANTY IF FOUND. The SW
series includes two AC inputs - each must be used as intended.
