Error E021:
Error 'E021' indicates that the pump requires more power than is per-
mitted. 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 lines are connected to the electronic
module, the effects of EMC (immission/interference resistance) 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 error no
longer occurs, there could be an external interfering signal 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.
