Function / connection
Voltage supply (observe the line voltage see indicated rating plate).
Relay output "K1" for fault indication.
For operation the relay is energized, connections
•
fault the relay is de-energized (
When switching off via enable (D1 = Digital In 1), the relay remains energized.
•
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.
MODBUS (RS-485) interface for programming by terminal or communication by
MODBUS-RTU.
Open-Collector pulse output for status display or speed display.
Digital input for enable.
