Bulletin 283 ArmorStart Distributed Motor Controller

Mode of Operation

Soft Start

This method has the most general application. The motor is raised from an initial torque value to full voltage. This initial torque is adjustable to 15, 25, 35, or 65% of locked rotor torque. The motor voltage is gradually increased during the acceleration ramp time, which can be adjusted from 1…45 s.



Current Limit Start

This starting mode is used when it is necessary to limit the maximum starting current. It can be adjusted for 150…450% of full load amps. Start times are selectable from 1…45 s.



Selectable Kick Start

A kickstart, or boost, at the beginning of the start mode is intended to provide a current pulse of 450% of the full load current. The kickstart time is adjustable from 0.5…1.5 s. This allows the motor to develop additional torque at startup for loads which may need an initial boost.



Soft Stop

The Soft Stop function can be used with applications that require an extended coast to rest. When enabled, the voltage ramp-down time can be selected from 1…90 s. The motor will stop when the motor voltage drops to a point where the load torque is greater than the motor torque.



Overload Protection

The Bulletin 283 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 allows for Class 10 overload protection. Ambient insensitivity is inherent in the electronic design of the overload.

Fault Diagnostics

Fault diagnostics capabilities built into the Bulletin 283 ArmorStart Distributed Motor Controller help you pinpoint a problem for easy troubleshooting and quick re-starting.

Factory-Installed Options

HOA Selector Keypad

The HOA Selector Keypad allows for local start/stop control.

Source Brake Contactor

An internal contactor is used to switch the electromechanical motor brake On/Off. The motor brake is powered from the main power circuit. A customer-accessible 3.0 A fuse is provided to protect the brake cable. Included is a 3-meter 3-pin cordset for connection to the motor brake, as standard.

Safety Monitor

The Safety Monitor Option allows for 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.
