Battery Failure Test
The battery should last the life of the terminal. The battery is
monitored continuously.
If the battery fails, a Minor Fault message is displayed. As long as
the terminal’s power stays on, there is no problem. However, if
power is cycled to the terminal, the firmware or application file is
still in flash memory or on the PCMCIA card, but the application is
not selected, and retained values are lost. Retained values include
configuration parameters, retentive data
Ċincluding last states,
current cursor point position, current cursor point status (enabled or
disabled)
Ċalarm history, and status information.
To clear the message and proceed, press the Clear button. Contact
your Allen-Bradley Representative to replace the board on which the
battery is situated. You will need to re-enter the configuration
parameters.
Watchdog Test
The Watchdog test verifies that the watchdog circuit can reset the
terminal. If the terminal fails this test, the following Major Fault
message is displayed:
Watchdog test failed
Contact your Allen-Bradley Sales Representative to service the
terminal.
To start up your terminal in Configure mode, set the Mode Select
Keyswitch to Configure and connect the power. The Mode Select
Keyswitch is at the rear of the terminal.
You’ll want to start up in Configure mode until you’ve configured
the terminal, downloaded your application file, and selected a current
application. When in Configure mode, the terminal will appear as a
faulted rack to your PLC (Remote I/O only) and will not be
recognized as a DH+ or ControlNet node.
