WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 5 AMP rating. Should the fuse need to be replaced, use
a 5 AMP FUSE approved by ASTA to BS 1362, ie one that carries the
ASA
mark.
T
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE
FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT
OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED
FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH
BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE SOCKET.
When an alternative type of plug is used, it should be fitted with a
5 AMP FUSE, otherwise the circuit should be protected by a 5 AMP
FUSE at the distribution board.
How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.

FE-2 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-2 chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the event of
one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing LED) and
then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be
displayed through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using this method.
Each time the software detects an error it is stored within the NVM. See T able 2.
