8. Error messages

If an error is detected, then a corresponding error message appears which must be
acknowledged by pressing any key. Possible error messages are as follows:

E.01

The switching points and hystereses have been set in such a way that the
resulting switch-back point is no longer within the permissible setting range.

Example:
Switching point is set to 65 °C, the hysteresis to 100 °C.

The setting is not correct since the resulting switch-back point is no longer within
the measuring range: the error message is displayed.

Action: Correct the settings

E.10

A data error has been detected in the saved settings. Possible causes are strong
electromagnetic interference or a component fault.

Action: Check all the settings (programming enable, switching points, switch-back points

and basic settings) and correct these if necessary. If this error occurs frequently,
please contact Hydac Service.

E.12

An error has been detected in the stored calibration data. Possible causes are
strong electromagnetic interference or a component fault.

Action: Disconnect the unit and re-connect. If the error message is still displayed, the unit

must be returned to the manufacturer for re-calibration or repair.

E.20

A short-circuit has been detected on a switching output.

Action: Eliminate the short circuit.
