High Pitch Alarm on 6100

[nauti1us]

I have a two year old Tunze set up. Two Tunze's on a controller.

When I plug them in, I get a high pitch alarm coming from one of the two aux boxes

I replaced both impellors from Tunze. This made no change.

I noticed that when I swap the actual control cables that come from the actual control module to the aux boxes, the alarm changes from one aux box to the other.

Please advize. I'm not in good shape with minimal current flow in my tank.

I am guessing you mean the cable form the multicontroller to the driver? I would suspect the cable is damaged or the socket has some salt creep. Inspect the socket and try replacing the cable. The controller came with 4 cables so you should have spares if you are only using 2 pumps.
