Description
The Bulletin 284 ArmorStart Distributed Motor Controller is an
integrated, pre-engineered, combination starter for variable
frequency AC drive applications. The ArmorStart offers a robust
IP 67/Nema Type 4 enclosure design, which is suitable for water
wash down environments. 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, 4 inputs and 2 outputs to be used with sensors and
actuators for monitoring 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 UL508C 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 rated 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.
