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) Temperature has risen above set temperature range.

(2) Thermistor has been short-circuited.

OFF during heating (reverse)

ON during cooling (normal)

– – –

(1) Temperature 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) Temperature 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) Temperature has fallen to a value much smaller than

the set temperature range.

OFF

E11 or E33 (see note 1)

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.

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.
