Protection Functions
Introduction The purpose of this chapter is to provide detailed information regarding the
protective trip and warning functions that the E1 Plus EtherNet/IP Module adds
to the E1 Plus Overload Relay. In this chapter, you will find considerable mention
given to parameters as they relate to these functions. For complete descriptions of
the programming parameters, refer to
Chapter 6- Device Parameters and Tags.
Trip Status / Identification The E1 Plus EtherNet/IP Module determines trip status and identification
through monitoring of reference signals inside the E1 Plus Overload Relay. On
power-up, it assumes that the E1 Plus Overload Relay is in a non-tripped
condition. For definitive feedback on trip status of the E1 Plus Overload Relay,
one of the E1 Plus EtherNet/IP module inputs may be wired to the N.O. auxiliary
contact (terminals 97 and 98) of the E1 Plus Overload Relay. Parameters 40 and
41 are used to configure the assignment of the inputs. For this function, use the
“OL Contact” configuration.
Trip Resetting The following options are available for resetting a tripped E1 Plus Overload Relay
with an E1 Plus EtherNet/IP module:
• Blue mechanical reset button located on the front of the E1 Plus Overload
Relay
• Setting Parameter 14, Trip Reset, to “Reset trip”
• Setting the trip reset bit in an output assembly from a logic controller
• Using a push button (N.O. contact configuration) wired to one of the
EtherNet/IP module inputs, programming the corresponding input
assignment parameter (40 or 41) to “Trip Reset”
• Setting the CIP Tag, Trip_Reset, to 1
Trip and Warning Enable Parameter 12, Trip Enable, allows the installer to enable or disable the jam trip
protective function.
IMPORTANT Setting parameter 16, Reset Mode, to “Automatic” does not result in
other reset commands being ignored.
