USER INFORMATION
If there is no 230 V power supply for the module or one of its 230 V
components (e.g. plug-in connection has not been made), the relevant
components (e.g. pumps) will not be activated.
You cannot recognise this error on the module in question since the
LED and the control functions work independently of this power
supply. Check cable connections thoroughly before re-fitting controller
casings.

z Position terminal cover and secure with the screws.
z Test the module function.
More detailed information can be found in the operating and servicing
instructions for control units CFB 9x0.
USER INFORMATION
If there is no 230 V power supply for the module or one of its 230 V
components (e.g. plug-in connection has not be made), the relevant
components (e.g. pumps) will not be activated.
You cannot recognise this error on the module in question since the
LED and the control functions work independently of this power
supply. Check cable connections thoroughly before re-fitting controller
casings.
