Error Messages
The Temperature Controller is provided with self-diagnostic functions, and will display the following error messages on the PV display in case of
an error.
Message
Cause
Control output
Alarm output
ffff
Input temperature has risen beyond the upper limit of
the temperature range by more than 20
°
C
OFF during reverse
(heating) operation
On during normal (cool-
ing) operation
Sends alarm signal in accor-
dance with the set alarm
mode.*
----
Input temperature has fallen below the lower limit of
the temperature range by more than 20
°
C.
On during reverse
(heating) operation
OFF during normal
(cooling) operation
Sends alarm signal in accor-
dance with the set alarm
mode.*
5.err
(flashes)
The thermocouple has burned out or short-circuit bar
has been removed. The platinum resistance thermom-
eter has burned out or A and B have been short-cir-
cuited.
OFF
Sends alarm signal in accor-
dance with the set alarm
mode. Proportional alarm out-
put is OFF, however.
e111
(flashes)
e333
(flashes)
Memory failure (
e111
) or A/D converter failure (
e333
)
has occurred. Temperature Controller must be repaired
if recovery is not made by turning power off once and
on again.

*When the J thermocouple is used, however, this error message is not displayed until the temperature has risen above the set temperature
range by more than 70
°
C.
**When the temperature resistance thermometer is used, this message is displayed when the temperature has fallen to –99.9
°
C.
The Temperature Controller displays the following error message in case of a Current Transformer input error.

Use these terminals when connecting a
platinum
resistance thermometer (remove short
bar from terminals 13 and 14).
Use these terminals when connecting a
thermocouple (do not remove short bar
from terminals 13 and 14).

Ground FG terminal 18 to avoid ambient noise.
Do not connect unused terminals.
