The following messages can be shown on the display during start up or exit from
programme mode.
“Shift reg clocking fault”
“Invalid # shift regs.Total # regs=xxx # input regs=xxx”
These messages indicate a hardware fault with the shift register bus that connects the
Controller, MAF/PSU, 8 Zone, and 8 Relay modules. The fault could be on the
Controller, the interconnecting FRCs or any of the connected boards. Try connecting
just the MAF/PSU on its own and with different cables to isolate the problem.
“Shift reg driver fault”
This message indicates a problem with the software driver for the shift register bus.
“Clock crystal timebase check fail”
This message indicates a hardware fault on the Controller.
“Clock chip ram write read fail”
“Clock register write read fail”

can be caused by a damaged EPROM or some other hardware fault on the Controller.
6.15.2 ERROR MESSAGES THAT CAN OCCUR ON ENTRY TO PROGRAM MODE
“This database is invalid and should be reinitialised-net dbase in non net panel”
This message is produced on entry to program mode when a database created with
networked F3200 or NDU software is used with non-networked software. This is
unusable and the database should be re-initialised and reprogrammed.

The following additional events can be recorded in the history or printed as an event on a
printer.
SHIFT REG BUS FAULT
This error indicates a fault with the bus connecting the Controller with the MAF/PSU,
zone modules and relay modules. It may be caused by a break or short in the flat ribbon
cable (e.g. bd unplugged), by temporary noise, or by a circuit board fault.
LCD DDRAM READ FAIL
