E1 Plus DeviceNet Communication Module

• ODVA Conformance Tested
• Unconnected Message Manager (UCMM) Support
• Get/Set Single Attribute Explicit Messaging
• Autobaud Network Rate Detection

INTEGRATED I/O
Integrated I/O allow simplification of the network architecture, providing local connection of motor starter related inputs and outputs.

• 2 Inputs – 24 Vdc rated, module supplied
• 1 Output – B300 rated

STATUS INDICATORS
Network Status: Green/red LED indicates the status of the network connection

OUT A: Amber LED that illuminates when the output contacts are commanded closed

IN 1 and 2: Amber LEDs illuminate when the user-connected device contact actuates

OPERATIONAL AND DIAGNOSTIC DATA
The DeviceNet module allows access to the following information, allowing continual monitoring of machine performance:

• Average Motor Current (as a percentage of motor rated current)
• Percentage of Thermal Capacity Usage
• Device Status
• Trip and Warning Identification
• Trip History (record of five most recent trips)

EXPANDED PROTECTION FUNCTIONS
The added protective functions provided by the DeviceNet module increase the protection of motor and load. Additionally, warning functions allow operations personnel to take action when motor performance parameters exceed permissive limits so that downtime can be avoided.

Overload Warning: By monitoring the percentage of thermal capacity utilization (TCU) signal of the E1 Plus overload relay, the DeviceNet module offers a setting range of 0…100% TCU.

Jam Protection: A quick response in taking a motor off-line in the event of a mechanical jam reduces the potential for damage to the motor and the power transmission components. Trip adjustments include a trip setting adjustable from 150…600% FLA and a trip delay time with a range of 0.1…25.0 seconds. A
separate warning setting is adjustable from 100…600% FLA.

Underload Warning: A sudden reduction in motor operating current can signal an abnormal condition such as pump cavitation or drive belt breakage. The underload warning function offers a setting range of 30…100% FLA.
