MAP. Refer to the communication card installation
documentation for more information.
The bars do not show
RED, YELLOW or
GREEN. Only the
background color is
shown. No sensor data is
available. The

correctly.
• Make sure that the RTC/PROGNOSYS communication
card is installed correctly. Select MAIN MENU>RTC
MODULES/PROGNOSYS>PROGNOSYS>ALLOCATION
MAP. Refer to the communication card installation
documentation for more information.
• Examine if the installation/configuration is setup correctly in
