Setup for Cat. No. 193-EC4 Current Monitor Relay
After the E3 Plus Current Monitor Relay is installed according to the guidelines specified in
this manual, apply power to the relay’s DeviceNet connector. After applying power, the
following sequence should occur:
1. The Trip relay should close 2.35 seconds later and the TRIP/WARN LED will not
flash (unless a Non-Volatile Fault previously existed or a fault condition is present).
2. At the same time, the NETWORK STATUS LED should flash green for
approximately two seconds, then red for a 1/4 second. If autobaud is enabled and the
E3 Plus Current Monitor Relay is connected to an active network, the green LED will
continue to flash once the baud rate has been determined. If the E3 Plus Current
Monitor Relay is not connected to an active network, the LED will not continue to
flash.
3. Once the E3 Plus Current Monitor Relay has been allocated by a master, the
NETWORK STATUS LED will turn solid green.
After being powered up, use the DeviceNet Configuration Terminal (Cat. No. 193-DNCT) in
order to set up the parameters. There are six basic parameters that need to be established
before using the trip functions. These parameters are listed under the ADVANCED SETUP
menu and include: L1 UC Trip Level, L2 UC Trip Level, L3 UC Trip Level, L1 OC Trip Level,
L2 OC Trip Level, and L3 OC Trip Level. After the parameters have been configured, enable
the specific trip bit as described in Table 7: for Parameter 24 (Trip Enable) to energize the relay
when conditions are met.
Once these parameters are set, the E3 Plus Current Monitor Relay is functional. Use the
ADVANCED SETUP menu to set other parameters per the specific application
requirements.
