Diagnostic display of the central module
– Four digit alphanumerical display,
– two LEDs for the general display of errors (CPU for the central modules, IO for the testable
input/output modules),
– two toggle switches to request detailed error information,
– push-button ACK resets the error indication;
in failure stop ACK behaves like restarting the system.
For further information on the diagnostic display and lists of error codes, refer to the documen-
tation "Functions of the operational system BS 41q/51q" (also on ELOP II CD).
Notes for start-up and maintenance
– Lifetime of the buffer battery (without voltage feeding):
1000 days at T
A
= 25 °C
200 days at T
A
= 60 °C
– It is recommended to change the buffer battery (CPU in operation) at the latest after 6
years, or with display BATI within three months
(Lithium battery, e.g. type CR 2477N, HIMA part no. 44 0000018)
– Check the bus station no. and transmission rate at switch S1 for correct settings
–
Important: When upgrading an F 8651 to an F 8651X module the fan concept has also to
be changed!
