Error E021:
Error 'E021' indicates that more power is required from the pump than is permissible. To en-
sure 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. A pump type
that is too small, especially in combination with viscous fluid, or too high a volume flow in the
system are the main causes of this error. When this error code is displayed, there is not an er-
ror 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 customer in
the electronic module. If the fault no longer occurs, there may be an external interference
signal on the communication lines that exceeds the applicable standard values. The pump
can only return to normal operation once the source of interference is remedied.

• To change to the menu mode, press the operating button. Menu number <6.0.0.0>
flashes on the display. By turning the operating button, it is possible to navigate in the
menu as usual.
• Press the operating button. Menu number <6.0.0.0> is displayed without flashing.
On the units display, the current incidence (x) as well as the maximum incidence of the er-
ror (y) are displayed in the format "x/y". Until the error can be acknowledged, pressing the
operating button again will cause a return to menu mode.

ror page.
Each error code has a separate error counter that counts all incidences of
the error within the last 24 hours.
The error counter is reset manually, 24 hours after "Mains ON" or when
"Mains ON" is repeated.
