Procedure following
power failure
Other Information
After any interruption to the electricity supply, the control unit automatically
switches back to the mode it was in before the outage.
If the control unit was in cleaning mode ...
...as soon as power is restored, a draining period is run for the time in [n70] in
order to empty the tank. Cleaning then continues from the start of the cleaning
stage the system was in at the time of the power failure.
Incorrect parameter configuration when switching on:
Factory configuration is restored automatically
If "dEFA" occurs in the display after switching on, the standard configuration
(factory setting) has been restored automatically. The control will not be ready for
use until confirmed with the SET-button.
This behavior occurs after a firmware-update or a factory reset. Procedure:
• Press button SET to confirm the factory reset
• Set and store original parameterization for the tank.
Displayed when invalid storage areas are detected.
When the control is switched on, it checks whether the parameter values in the
EEprom-storage have been changed inappropriately. (This is possible in rare cases
due to EMC-effect or lightning, for example).
If an impermissible change is detected, "EEP" is displayed, the control is not ready
for operation.
Procedure:
• Press and hold the OFF / SET / UP / DOWN buttons simultaneously until
"dEF" appears in the display: The default configuration (factory setting)
has been restored.
• Press button SET to confirm the factory reset.
• Set and store original parameterization for the tank.
NOTE:
If "EEP" appears again on the display after the factory reset and after another OFF
and ON-switching, the control is irreparably defective.
Memory fault Automatic factory reset
after update
The controller was reset to factory settings
after a software update.
