Error Messages
The Temperature Controller is provided with self-diagnostic functions, and will display the following error messages if an error occurs.
Message Cause Control output
FFF (1) T emperature has risen above set temperature range.
(2) Thermistor has been short-circuited.
OFF during heating (reverse)
ON during cooling (normal)
– – – (1) T emperature has fallen below set temperature range.
(2) Thermistor has broken.
ON during heating (reverse)
OFF during cooling (normal)
FFF (blinks) (see note 1) (1) Failure has occurred in thermocouple or platinum
resistance thermometer .
(2) T
emperature has risen to a value much greater than
the set temperature range.
OFF
– – – (blinks) (see note 1) (1) Failure has occurred in platinum resistance
thermometer.
(2)
Polarities (positive and negative) of thermocouple have
been reversed.
(3) T emperature has fallen to a value much smaller than
the set temperature range.
OFF
E1 1 or E33 (see note 1) Memory failure (E1 1) or A/D converter failure (E33) has
occurred. T emperature Controller must be repaired if
normal operation is not restored by turning power OFF
once and ON again.
Both control output and alarm output
are OFF .
Note: 1. The key operations are disabled.
2. The models with alarm output produce alarm output according to the alarm output setting when the message “FFF” is displayed (or
blinks), indicating that the temperature has risen above the set temperature range. Similarly , the alarm output is produced when the
message ”–” is displayed (or blinks), indicating that the temperature has fallen below the set temperature range.
