E06 (-) -> EARTH
a) line is grounded
b) The connection for the external AI is grounded
+
_
+
_
(D)
Search for the ground fault. In particular, note
connections for line devices with grounded
components, shielded cables, etc.
E07 (+) -> EARTH
line is grounded. The exact position of the error cannot
be identified by the FDUL221 line tester.

?
?
Find the faulty location by separating the parts
of the detector line and checking the separated
line parts (e.g. ½, ¼, ). Also refer to the tips
E08 series R
High resistance
+
_
+
_
(D)
Resistance in the detector line is too high.
Check the lines and the connection points
(terminals). Ensure that the line is not too long.
Limit values: See error E05
Use the 'Measure Device' menu item.
E09 More err
The error list is limited to a maximum number of error
messages that can be displayed. However, more errors are
available than can be currently displayed.
Rectify the errors displayed and then read in
the detector line again. The errors that were
not originally displayed will then be shown.
E10 >252 dev
There are too many devices on the detector line that has
been read-in. A maximum of 252 devices may be installed
on a FDnet/C-NET detector line.
The read-in loop or stub must be divided into
several loops or stubs with less line devices.
E11 bad TTap
A sub-stub is not permitted in this location.
Note: This error number indicates several line devices as
faulty.
A branch is not allowed. Change the wiring.
Ensure that a 'sub-stub on stub' topology has
not been wired. Only one or several individual
sub-stubs can branch from a loop.
E12 >2 TTap
Several sub-stubs directly after one another without a line
separator in between are not permitted.
Note: This error number indicates several line devices as
faulty.
Ensure that there is a line device, e.g. a line
separator, between two sub-stubs branching
off from the loop.
Only one sub-stub may branch off from a loop
between two line devices on the detector line.
