What does it mean if my ZIEHL-ABEGG Control Unit displays 'Error MODBUS Com Fan: 8'?
This indicates that the connection to the MODBUS Master interface is interrupted or the entered member count is too high. The ZIEHL-ABEGG Control Unit continues working unchanged. Check the member count and the MODBUS connection.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Motor fault Fan: 3'?
This indicates a motor fault at member with address 3. The ZIEHL-ABEGG Control Unit continues running unchanged. A reset is required on the member (refer to the operating instructions of the device concerned).
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Line Fault Fan: 6'?
This indicates a line failure at member with address 6. The ZIEHL-ABEGG Control Unit continues running unchanged. Check the line supply of member.
Why is there no display on my ZIEHL-ABEGG Control Unit?
The possible causes are: * No line voltage. * Jumper J1 for USB interface plugged. To solve this: * Check if line voltage is available. The unit switches OFF and automatically ON when the voltage has been re- stored. * Check line fuse. * Check jumper J1, pull off or only plug to one PIN.
Why is my ZIEHL-ABEGG Control Unit showing 'OFF'?
The ZIEHL-ABEGG Control Unit might be switched OFF by an external contact because the function |1D| = enable is programmed for Digital In.
