Problem 1
The LogicDrive RLD80 does not respond to the control signal.
Observation 1
The RLD80 fails to respond to commands using the 0-10 V DC control signal.
Cause 1
The RLD80 has not been taught in yet.
Solution 1
Teach in the RLD80 according to the procedure described in this manual.
Cause 2
The 24 V DC supply voltage has failed.
Solution 2
Check the supply voltage and restore it if necessary.
Cause 3
The RLD80 is not receiving the control signal.
Solution 3
Check the cables and connections and make sure they are securely fastened.
Cause 4
The RLD80 has overloaded in a particular rotational direction (blink code 6).
Solution 4
Check the system and correct the overload that has occurred. Reverse the
rotational direction of the RLD80 to cancel the lock function. You will then be able
to operate the RLD80 in the rotational direction that was previously locked.
Cause 5
The RLD80 has experienced multiple overloads (blink code 7 or 8).
Solution 5
Check the system and correct the overloads that have occurred. Switch off the
24 V DC supply voltage of the RLD80 and switch it back on after about 5 seconds.
The RLD80 should now be operational again.

● The taught-in end positions (are they still correct for the system being driven).
● The operation of the emergency power supply when it was used.
