DIAGNOSTICS BUTTON
The Diagnostics button displays analog and digital I/O status of the Burner Control and is meant only for diagnostics and troubleshooting
purposes. A snapshot of the diagnostic status is displayed and updated once per second as it changes in the control.
The digital I/O data is displayed as LEDs that are either on (green) or off (red) (see Figure 50). Not all digital I/O can be displayed at
the same time on the page, so a horizontal scroll bar is used to move the view left and right to show all digital I/O data.
The control analog I/O can also be viewed on the OI Display. A snapshot of the diagnostic status is displayed and updated as it
changes in the control.
The analog I/O data is displayed as bar charts with I/O level represented in the I/O range (see Figure 51) Analog I/O that is not
enabled for the installation displays a blank I/O level. Not all analog I/O can be displayed at the same time on the page, so a horizontal
scroll bar is used to move the view left and right to show all analog I/O status.
SYSTEM CONFIGURATION (S7999D OI DISPLAY ONLY)
The OI Display has some functions related to general configuration for the control in the end user installation. Pressing the Display
Refresh button invokes a search procedure (see Figure 52). A new R7910A Hydronic Control is identified by “Unknown” status next
to its name in the boiler/water heater system list (see Figure 53). “Unknown” indicates that configuration data has not been retrieved
from the control yet.
The control connected to the Modbus network is indicated to the user after the search procedure has concluded.
Once the control is located it must be synchronized with the OI Display before it can be displayed. New controls are not displayed on
the Home page until this synchronization is performed.
