How to fix an Acuity Controls Controller that is powered but does not turn on?

If your Acuity Controls Controller is powered but not turning on, there are several potential causes. First, check if the fuse has blown by disconnecting the power, inspecting the fuse, and then reconnecting the power. Another cause might be inconsistent power supply polarity between the controllers and the transformer; verify that the COM terminal of each controller is connected to the same terminal on the secondary side of the transformer. Finally, the transformer might not be powerful enough to supply all the controllers. Verify that the transformer used has sufficient power.
