Error Messages
The Digital Controller is provided with self-diagnostic functions, and will display an error message on the PV display when an error is detected.
Message Cause Control output Alarm output
Pulse output Current output*
ffff
Input value has exceeded the upper-limit of
input range by 10% FS. OFF during re-
verse operation
ON during nor-
mal operation 4 mA during re-
verse operation
20 mA during nor-
mal operation The output will turn ON ac-
cording to the alarm mode
for an input value that is
greater than the upper limit
of the input range by 10%
of full scale.
––––
Input value has fallen below the lower-limit of
input range by 10% FS. OFF during re-
verse operation
ON during nor-
mal operation 20 mA during re-
verse operation
4 mA during nor-
mal operation The output will turn ON ac-
cording to the alarm mode
for an input value that is
less than the lower limit of
the input range by 10% of
full scale.
5.err
(flashes)
The input is disconnected or shorted or the
input value has greatly exceeded the input
range. OFF Approx. 1 mA The output will turn ON ac-
cording to the alarm mode
when the input goes to
maximum except in the
proportional alarm mode,
in which it will remain OFF.
e111
(flashes)
e333
(flashes)
Memory failure (
e111
) or A/D converter failure
( e333 ) has occurred. Digital Controller must
be repaired if recovery is not made by turning
power off once and on again.
OFF Approx. 1 mA OFF
Note: If the display range (–999 to 9999) is exceeded, “FFFF” or “––––” will be displayed.
Input Error Displays
The following displays will appear when the input is not within specifications for the various types of input.
