Error Messages

The Temperature Controller is provided with self-diagnostic functions, and will display the following error messages if an error occurs.
Message
FFF
– – –
FFF (blinks) (see note 1)
– – – (blinks) (see note 1)
E11 or E33 (see note 1)
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.

Cause
(1) Temperature has risen above set temperature range.
(2) Thermistor has been short-circuited.
(1) Temperature has fallen below set temperature range.
(2) Thermistor has broken.
(1) Failure has occurred in thermocouple or platinum
resistance thermometer.
(2) Temperature has risen to a value much greater than
the set temperature range.
(1) Failure has occurred in platinum resistance
thermometer.
(2) Polarities (positive and negative) of thermocouple have
been reversed.
(3) Temperature has fallen to a value much smaller than
the set temperature range.
Memory failure (E11) or A/D converter failure (E33) has
occurred. Temperature Controller must be repaired if
normal operation is not restored by turning power OFF
once and ON again.
