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 pro-
tects itself by switching the pump off if an overload lasts more than 1 minute. The most
common causes of this error are a pump type of too small dimensions, 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 or control cables 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 communication cables installed by the cus-
tomer in the electronic module. If the fault no longer occurs, there may be an external
