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 I
2
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.
LED Status Indication
The LED Status Indication provides 4 status LEDs and a Reset button.
The LEDs provide status indication for the following:
! POWER LED
The LED is illuminated solid green when control power is present
and with the proper polarity
! RUN LED
This LED is illuminated solid green when the motor is running
! NETWORK LED
This bicolor (red/green) LEDs indicates the status of the
communication link
! FAULT LED
Indicates Controller Fault (trip) condition
! The “Reset Button” as a local trip reset.
Inputs
The inputs are single keyed (2 inputs per connector), which are
sourced from DeviceNet power (24V DC), with LED status indication.
Outputs
The outputs are dual key connectors. Which are sourced from the
control voltage power, which can be either, 24V DC, 120V AC or
240V AC with LED status indication.
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.
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.
provided as standard which are a dual key connector, 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.
The HOA Selector Keypad with Jog Function allows for local
start/stop control with capabilities to JOG and to Forward/Reverse
motor direction.

EMI Filter
The EMI Filter option is required if the Bulletin 284 ArmorStart
Distributed Motor requires to be CE compliant. If the EMI Filter is
selected, a 3 meter shielded 4 conductor cordset is provided as
standard. This option is only available with sensorless vector control.
A 3 meter, 3 pin cable for connection to a dynamic brake module is
provided as standard when this option is selected. See Accessories for
available dynamic brake modules.
An internal contactor will be sourced from control voltage to isolate
the load side of the Bulletin 284 ArmorStart Distributed Motor
Controller. When control power is applied the output contactor is
closed and when control power is removed the output contact opens.
There is no switching element such as a relay in the system. If control
power is lost then the output contactor will open since its coil power is
lost. A sequenced stop involving the output contact cannot be
performed.
Dynamic Brake Connector
Output Contactor
The Bulletin 284A ArmorStart Distributed Motor Controller allows
connectivity to the ArmorPoint backplane. The ArmorPoint I/O system
can communicate using DeviceNet, ControlNet and 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 outputs that are
Source Brake Contactor
An internal contactor will be used to switch the electromechanical
brake on/off. This contactor’s coil will be driven by the auxiliary relay
output of the ArmorStart Distributed Motor Controller. A 3 meter, 3
pin cable for connection to an electromechanical brake is provided as
standard when option is selected.
Shielded Motor Cable
A 3 meter shielded 4 conductor cordset is provided instead of the 3
meter unshielded 4 conductor cordset. If the EMI Filter is selected, a 3
meter shielded 4 conductor cordset is provided 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 contactor.
0…10V Analog Input
The Bulletin 284 Distributed Motor Controller with Sensorless Vector
Control provides a 0…10V analog input. The 0…10V Analog Input,
15 A, factory-installed option provides a 0…10V external frequency
command from the 0…10V or +/-10V analog input or remote
potentiometer. A 5-pin micro receptacle is provided for connectivity
for customer connection. A shielded 5-conductor cordset or patch cord
is recommended.
