You can switch over between automatic speed control by the setting signal and operation at full speed
via the digital input D1 (Digital In 1).
Activation via

Danger due to electric current
Never apply line voltage to the digital input!

Relay output
“
K1
”
for fault indication
An external fault indicator is available over the potential-free contact of the built-in relay (max. contact
rating see Technical data and connection diagram).
The relay is energised during operation. I.e. on the ECblue BASIC-MODBUS contacts 11-14 are
bridged, and on the ECblue BASIC contacts 13-14. In case of failure, the relay is de-energised (see
Diagnostics/Faults).
Changeover contact for ECblue BASIC-MODBUS
NO contact in ECblue BASIC
Information
After switching on the line voltage, an initialisation time of a maximum 7.5 seconds is required for the
device's electronics to be operational. Subsequently, a reliable status message will be possible. If no
malfunction is detected, the relay will be energised after the initialisation time.
Since both line voltage
fl
uctuations and ambient conditions affect the initialisation time, a different
delay might occur in individual cases.
