Curtis 1236-6304 Controller

Curtis 1236‑6304 is a 48–80 V, 300 A AC induction motor controller that incorporates an embedded field‑programmable logic unit for advanced drive control. Common failure modes in this class include power supply over‑voltage or ripple causing the FPL logic to lock up, loss of phase current leading to tripping of the internal protection relays, and degradation of the heat sink or fan resulting in overheating. First‑check diagnostics: verify that the input voltage is within spec and free of excessive ripple; inspect all I/O terminals for loose connections or corrosion; review any stored error codes on the controller’s diagnostic display or via its communication port.[oss-gpt-20b]
