Description

The Bulletin 284 ArmorStart Distributed Motor Controller is an integrated, pre-engineered starter for variable frequency AC drive applications. The ArmorStart offers a robust IP67/NEMA Type 4 enclosure design, which is suitable for water wash-down environments. The ArmorStart products are also offered with NEMA Type 4X rating, suitable for environment wash down with caustic chemicals used in the food and beverage industry. The wash-down rating is 1000 psi for the NEMA Type 4X rated devices. The modular plug-and-play design offers simplicity in wiring the installation. The quick disconnects for the I/O, communication, and motor connection reduce the wiring time and eliminate wiring errors. The ArmorStart offers, as standard, four DC inputs and two relay outputs to be used with sensors and actuators respectively, for monitoring and controlling the application process. The ArmorStart’s LED status indication and built-in diagnostics capabilities allows ease of maintenance and troubleshooting. The optional Hand/Off/Auto (HOA) keypad allows for local start/stop control at the ArmorStart Distributed Motor Controller.

The Bulletin 284 ArmorStart Distributed Motor Controller offers short circuit protection per UL 508C and IEC 60947-1. The ArmorStart is rated for local-disconnect service by incorporating the Bulletin 140 Motor Protector as the local-disconnect, eliminating the need for additional components. The ArmorStart Distributed Motor Controllers are suitable for group motor installations.

Mode of Operation

Volts per Hertz (Sensorless Vector Performance)

This method provides excellent speed regulation and high levels of torque across the entire speed range of the drive, and improved speed regulation even as loading increases. Basic control yields the most cost effective performance when sensorless vector control is not required.

Description of Features

Overload Protection

The Bulletin 284 ArmorStart Distributed Motor Controller incorporates, as standard, electronic motor overload protection. This overload protection is accomplished electronically with an I2t 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.

Gland Plate Entrance

The ArmorStart product offers two different methods for connecting incoming three-phase and control power to the device. One method offered is the traditional conduit entrance which provides a 3/4 and 1 in. conduit hole opening for wiring three-phase and control power. The second method offers connectivity to the ArmorConnect power media. Factory installed receptacles are provided for connectivity to both three-phase and control power media.

Motor Cable

With every Bulletin 284 ArmorStart Distributed Motor Controller, a 3–meter unshielded 4-conductor cordset is provided with each unit as standard. If the optional EMI filter is selected, a 3–meter shielded 4-conductor cordset is provided with each unit as standard.

LED Status Indication

The LED Status Indication provides four status LEDs and a Reset button. The LEDs provide status indication for the following:


Inputs

The inputs are single keyed (two inputs per connector), which are sourced from DeviceNet power (24V DC), with LED status indication.

Outputs

Two dual-key relay output connectors are supplied as standard. The outputs are sourced from the control voltage power, which can be either, 24V DC, 120V AC, or 240V AC with LED status indication.

Fault Diagnostics

Fault diagnostics capabilities built into the Bulletin 284 ArmorStart Distributed Motor Controller help you pinpoint a problem for easy troubleshooting and quick re-starting.



Network and Expandable I/O Capabilities

The Bulletin 284D ArmorStart Distributed Motor Controller delivers enhanced control to access parameter settings and provides fault diagnostics, and remote start/stop control. DeviceNet is the communication protocol, provided with the ArmorStart including DeviceLogix.

The Bulletin 284A ArmorStart Distributed Motor Controller allows connectivity to the ArmorPoint backplane. The ArmorPoint I/O system can communicate using DeviceNet, ControlNet, or EtherNet communication protocols. In addition to the different network protocols, the ArmorPoint Distributed I/O products allow the I/O capability to be expanded beyond the standard two outputs. The two dual-key relay output connectors are supplied as standard. The outputs are sourced from the control voltage power of 24V DC, 120V AC, or 240V AC. LED status indication is also provided, as standard with ArmorPoint. When using the ArmorPoint, a maximum of two ArmorPoint Distributed Motor Controllers can be connected to the ArmorPoint Distributed I/O product.
