Cerus Industrial (Hillsboro, OR) offers the BAS (Building Automation Starter) motor controls that incorporate the company’s patentpending Smartstart™ Control Module for integration with digital controls. The starters accept dry voltage inputs (wide range 12-250VAC) for activation by control systems without interposing relays. Other control options include auto run, fireman’s override, fault, proof of flow (detects loss of load), and SmartStart predictive calibration (fault alarm). Integrated LED pilot lights and Hand/Off/Auto keypad are standard.
A single model accepts 208-600VAC and motor loads up to 40A, eliminating discrete thermal overloads. Upon motor start-up, the electronic Smartstart overload allows the starter to look for a safe operating range based on motor starting current. If the starter isn’t calibrated within that range, an alarm is activated and the starter contactor is opened. The BAS also protects against locked rotor, stall, and other undesirable starting conditions.
