FMS Fault Correction
Load signal (D)
Aids
D1
Load signal does not show
Cause: load transducer not on minimum
the minimum value
Run transducer down manually
_____________________________________________________________________________________________________
D2
Load signal cannot be changed
Check whether fault present
if so
Rest fault
(selector switch on status switch up)
if not
Check load circuit
If only "000" is displayed
-
current input poles reversed
_____________________________________________________________________________________________________
D3
When changing a point,
Load rating was not run precisely to the point previously programmed.
"Err" or >20 point appears on the
display instead of "Point"
Repeat process
but this time
Run precisely to load rating
It is possible that the digital display shifts after the load rating, if
-
the load rating is right at the edge of the adjustment range
-
there are marked fluctuations on the connection leads
For this reason:
Run load rating to the middle of the adjustment range
(flashing number after the load rating)
_____________________________________________________________________________________________________
D4
Load signal cannot be set higher
Load potentiometer wrongly connected (middle reversed with outer)
than approx. 500, although the
or
5k
S
potentiometer runs
the internal wiring of the configuration cards causes the FMS to expect a
over the full range
current signal as load default
Check wiring
Check that the correct configuration jumpers are inserted,
if not, change them

D5
Load value does not attain the
If the load transducer is in the basic position but does not emit
bottom value indicated
the lowest possible value.
Make sure that this position of the load transducer is the lowest load
rating position that occurs in operation
