Error Displays and Causes

E5L-A

@

When a thermistor disconnection occurs, the built-in relay operates at the OFF side (when NO contacts are used).

E5L-C

@

When an error occurs, the display shows the error code. Take the necessary measures, referring to the following table.

Note: 1.

Errors are not displayed while settings are being changed, except for memory errors. The control output status will be as shown in the 
above table while the set temperature or hysteresis is being set. The control output will be OFF while the temperature input shift or direct/
reverse operation setting is being set. Key operations will be possible when an error occurs, except for a memory error.

2.

The setting protection indicator (

) and set value indicator ("SV") will be continued even when settings are protected, except when a 

memory error occurs.
