17 Error messages
If an error is detected, then a corresponding error message appears which must be acknowl-
edged by pressing any key. Possible error messages are as follows:
Er.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 180 bar, the hysteresis to 200 bar.
Action: Correct the hysteresis setting.
Er.02 The minimum difference in the given measuring ranges between lower display
range and upper display range is too low.
Examples:
Lower display range = 0.025 and upper display range = 0.075
Lower display range = 0.25 and upper display range = 0.75
Lower display range = 2.5
and upper display range = 7.5
Lower display range = 25 and upper display range = 75
Action: Correct measuring range settings as follows:
Lower display range = 0.0XX => minimum value for upper display range = 0.1XX
Lower display range = 0.XXX => minimum value for upper display range = 1.XXX
Lower display range = X.XXX => minimum value for upper display range = 1X.XX
Lower display range = XX.XX => minimum value for upper display range = 1XX.X
Er.03 The difference of the measuring values between sensor 1 and sensor 2 is outside
the measuring range.
Action: Check all the settings (programming enables, switching points, switch-
back points and basic settings) and correct them if necessary. If the errors occur
frequently, please contact HYDAC Service.
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 enables, switching points, switch-
back points and basic settings) and correct them if necessary. If the errors occur
frequently, please contact HYDAC Service.
The display shows four horizontal segments. This means that the sensor supply
voltage (+12 V, plug X2.6) is overloaded.
Action: Ensure that the above mentioned supply voltage of +12 V has not short-
circuited against AGND. Check that the maximum current has not exceeded
100 mA.
