Error messages
There are three error messages that can be displayed during
normal operation. If you get a display of Er.F it means that
the train was moving faster then 999 mph.
Er.F
The message Er.S indicates that the train was moving slower
then 1 mph.
Er.S
You will see the Er.S message if you have inadvertently
tripped one of the sensors by throwing a shadow over it while
working on the layout (on dimly lit layouts just walking by
could cause this). It takes about two minutes (on the 1/100
jumper setting) for this message to be displayed. The unit will
display normal speed for the next train whenever any of these
errors occur.
If the message Er.1 is displayed it means that both sensors
were tripped at the same time. The probable cause is turning
out or blinking the lights, disconnecting a sensor cable or a
really, really fast train (or finger). When this occurs the unit
will reset after about 2 seconds and normal operation will
resume.

Several things may cause this. The cable could be plugged in
