E1 Plus Overload Relay (EtherNet/IP) (PE1PlusE) Guidelines Use this instruction to monitor an Allen-Bradley® E1 Plus motor overload relay by using the catalog number 193-ETN EtherNet/IP interface sidecar. This instruction monitors the overload relay for warning and trip conditions. E1 Plus Overload Relay Specifications Side-mount Expansion Modules By using optional side-mount expansion modules, you can expand the functionality of the E1 Plus overload relays cost effectively and enhance machine operation and protection. Direct mounting to the left side of the 193-EE and 592-EE E1 Plus overload relays means that only. E1 Plus Electronic Overload Relays The user shall provide one current transformer (CT) for each motor phase, and shall connect the CT’s secondary leads to the appropriate E1 Plus overload relay power terminals, as shown in current transformer’s wiring diagrams. The CT shall have the appropriate ratio (refer to the. Protection enhanced. Direct mounting to the left side of the 193-EE and 592-EE E1 Plus overload relays means that only 18 mm is added to the overall product width. The side-mounted accessory modules electronically interface with the E1 Plus overload relay so that all control circuit connections are made at the E1 Plus overload relay terminals. Cat 193-ejm).

Parameter 13,
Warning Enable, allows the installer to enable or disable the
overload, jam, underload, and communication warning protective functions.
Overload and Phase Loss
Protection
Thermal overload and phase loss trip protection is provided exclusively by the E1
Plus Overload Relay. The E1 Plus Overload Relay provides uninterrupted
protection to the motor, even in the event of an E1 Plus EtherNet/IP Module
failure. Settings for FLA and trip class are found directly on the E1 Plus Overload
Relay.
Overload Warning
The E1 Plus EtherNet/IP Module continuously monitors the E1 Plus Overload
Relay's percentage of thermal utilization signal. Parameter 2,
%Therm Utilized,
provides this value.
Parameter 17,
OL Warn Level, is used to adjust the setpoint to alert for an
impending overload trip and is adjustable from 0…100% TCU.
The E1 Plus EtherNet/IP Module will indicate an overload warning if all the
following conditions are met:
• No warning currently exists
• Overload warning is enabled
• %Therm Utilized is equal to or greater than OL Warn Level
When the overload warning conditions are satisfied, the following will occur:
• Bit 0 in Parameter 4, Warning Status, will go to “1”
• Bit 1 of Parameter 10, Device Status, will go to “1”
ATTENTION: The Trip Enable settings should not be altered during
machine operation, as unexpected behavior could occur. This may
result in an unintended actuation of controlled industrial
equipment, with the potential for machine damage or serious
injury to personnel.
IMPORTANT
The reset mode DIP switch adjustment is overridden by the E1 Plus
EtherNet/IP module parameter 16, OL Reset Mode, while the E1 Plus
EtherNet/IP module is powered.
IMPORTANT
%Therm Utilized will stabilize at a value of approximately 88% with
the motor operating continuously at rated current.
