Calco Mfg KL-1 Controller

The Calco KL‑1 is a motor‑protection base unit that accepts 120 VAC/60 Hz input and supplies up to 10 A (≈⅓ HP) to the motor. Common failures on this model include worn relay contacts, overcurrent or short‑circuit protection tripping, insulation degradation between input/output terminals, and failure of the internal control board (power supply, logic ICs). First‑check diagnostics: verify that the 120 VAC supply is present and within spec; inspect all input and output connections for corrosion or loose wiring; and review any diagnostic LEDs or error codes displayed on the unit’s panel.[oss-gpt-20b]
