Fig. 38. Call for Service edit commands
The edit commands are accessed from the edit line from either the first or last character positions. When the input focus
is on the first character position of the edit line a left arrow button action navigates the input focus down to the navigation
bar commands. When the input focus is on the last character position in the edit line a right arrow button action also
moves down to the navigation bar.
The right and left arrow buttons are used to tab between the edit commands on the navigation bar. Pressing the OK
button causes the highlighted command to be executed. When the “OK” or “Cancel” command is executed the edit page is
exited and control returns back to the Call for Service menu. Pressing the up or down arrow button from the command
line navigates the input focus back to the edit text line.
The message can be tested to see what it would look like when a lockout occurs by selecting the “Test message” line (see
Fig. 39). The message continuously displays until the user presses any button to stop. After a button is pressed and
released the simulation is stopped and control returns back to the Call for Service menu.

The lockout fault code is not displayed in the first line, but instead a message to press any button to stop the test is given.
Modbus Setup
Modbus setup is accessed from the Display Menu (see Fig. 40). The current settings of the following Modbus parameters
are displayed:
• Interface enable/disable option
• Slave address
• Baud rate (speed)
•Parity
• Endian order (for 32-bit registers)

The up and down arrow buttons are used to scroll down to the line of the parameter to edit. Pressing the right arrow or OK
button navigates to the parameter edit page (unless a display login is required first). Pressing the left arrow button exits
this page and returns back to the Display menu.
The Modbus interface can be enabled or disabled by selecting the “Interface” line and pressing the right arrow or OK
button (see Fig. 41). When the interface is enabled the RS-485 pins of the edge connector (terminals 1-3) accepts
Modbus communication requests as a Modbus slave. When the interface is disabled the RS-485 pins provide a
communication bus for other 7800 SERIES accessories (see “Wiring” on page 5). The current enable setting is displayed
initially.
