Mode of Operation

Full-Voltage Start

This method is used in applications requiring across-the-line starting. Full in-rush current and locked-rotor torque are realized. The ArmorStart Bulletin 280 offers full-voltage starting, and the Bulletin 281 offers full-voltage starting for reversing applications.



Overload Protection

The Bulletin 280/281 ArmorStart Distributed Motor Controller incorporates, as standard, electronic motor overload protection. This overload protection is accomplished electronically with an I²_t algorithm. The ArmorStart’s overload protection is programmable via the communication network providing the user with flexibility. The overload trip class can be selected for class 10, 15, or 20 protection. Ambient insensitivity is inherent in the electronic design of the overload.

Factory-Installed Options

HOA Selector Keypad

The HOA Selector Keypad allows local start/stop control.

Safety Monitor

The Safety Monitor Option allows independent monitoring of the output status of the device. The function is implemented using a normally closed contact which complies with IEC 60947-5-1 for mechanically linked contacts. Two terminal blocks are provided as the inputs which maybe used with an external safety circuit. The external safety circuit monitors the status of the isolation contactor.
