Programming the RT-Ex15
(Note: Model number RT-Ex15 is used for reference go indicate programming is common to all models. This has
no effect on the ratings of any RT-Ex15 versions)
Power must be applied to perform programming and set-up of the RT-Ex15. The RT-Ex15 can
be programmed in the hazardous area with the cover on using the magnetic switches (if function
is enabled) or OUTSIDE THE HAZARDOUS AREA with the cover removed using the
programming buttons. IF THE COVER IS REMOVED FOR PROGRAMMING THIS
MUST BE DONE OUTSIDE THE HAZARDOUS AREA.
After variable programming is completed and the desired display mode is selected, disconnect
the power and tightly install the RT-Ex15 cover before installation in the hazardous area. See
Wiring Connections on page 3.
To scale the rate or total display, output, or limits, the RT-Ex15 will require programming of the
RATE, TOTAL, ANALOG OUT and LIMIT variables. All RT-Ex15 parameters are
programmed from the corresponding display screen. For example, to program the rate scaling-
factor, decimal resolution and engineering units for display, select the RATE A GT display. This
manual will take the user through the various programming steps in order.
Startup Message
The RT-Ex15 displays an initial window at power up. After a second the following message will
be displayed in the window for approximately 2 seconds. After this message, the display will
revert to the last active Display Mode selected.
LOAD VARS – Indicates that the variables are being recalled from EEPROM.
TURN ON – Increments on each power-on cycle of RT-Ex15.
MEM LEFT – Memory life indicator displays % of memory life remaining in .1% increments.
The RT-Ex15 stores programmed variables and retained totalizer values in
EEPROM (electrically erasable memory). The limit on the number of times
memory can be re-written results in a minimum EEPROM life of 5 years with
continuous use. This memory IC can be replaced by AW Company if it
becomes necessary. Program variables require reprogramming after memory IC
change.
VERSION – Indicates the software version installed in the RT-Ex15.
