Additional explanations of
error codes Error E021:
Error “E021” indicates that the pump requires more power than is
permitted. To ensure that the motor and electronic module do not
suffer irreparable damage, the drive protects itself by switching the
pump off if an overload lasts more than 1 minute.
The most common causes of this error are a pump that is configured
too small, especially when pumping viscous fluids, or an excessive
volume flow in the system.
When this error code is displayed, there is not an error in the electronic
module.
Error E070; possibly combined with error E073:
If additional signal lines or control cables are connected to the elec-
tronic module, the effects of EMC (immission / interference resist-
ance) may interrupt communication. This results in error code “E070”
being displayed.
You can check this by disconnecting all the communication lines
installed by the customer from the electronic module. If the fault no
longer occurs, there could be an external signal interfering on the
communication line(s) that exceeds the applicable standard values.
The pump can only return to normal operation once the source of
interference is remedied.
