Industrial start, stop controls
The ISS motor controls from Cerus accepts dry voltage inputs of up to 250 V AC for activation. One model can accept 208-600 V AC and motor loads up to 40 A.
The ISS (Industrial Start/Stop) motor controls from Cerus incorporate the company’s Smartstart Control Module for seamless integration with digital controls. The starters accept dry voltage inputs (wide range 12-250 V ac) for activation by remote control systems without interposing relays. Other control options include remote run, shutdown, fault, proof of flow (detects loss of load), and SmartStart predictive calibration (fault alarm). Integrated LED pilot lights and remote keypad are standard, simplifying unit setup and verification.
One model accepts 208-600 V ac and motor loads up to 40 A, eliminating discrete thermal overloads and numerous contactor coil voltages typically required with other motor starters. The broad operating ranges enable distributors to eliminate thousands of dollars on unnecessary stock and mis-sizing issues, while providing a superior off-the-shelf starter solution.
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. This feature is meant to protect against operators increasing the overload to overcome motor jams or other impedances and to provide base line protection should the starter not be calibrated. The ISS with Smartstart also protects against locked rotor, stall, and other undesirable starting conditions.
The ISS with Smartstart is available in UL Type 1, 3R, and 4 enclosures.
