Test Of The Relays; Operational Status Signaling - Eaton Power Xpert C445 Safety Manual

Test of the Relays

Check the wiring of the relays by calling Test TRIP function in
either of the following ways
BCM Test/Reset button
•
Fieldbus Control word
•
ModBus register = 600
This simulates the tripping of the overload relay. The main cir-
cuit to the motor has to be interrupted by the relay.
After the Test button is released, the overload relay must be
reset in the same way as after a trip.

Operational Status Signaling

After switching on the motor, the overload relay signals the
operating state via the integrated status-LED. The LED signals
the operating state of the relay in the following ways:
An LED test is performed after every
reset or whenever commanded to
from the network. LED tests will
cycle through both colors on bicolor
LEDs. The test lasts ~2 seconds.
Output Status LEDs:
ON = Output active
OFF = Output Inactive
Input Status LEDs:
ON = Input active
OFF = Input Inactive
Device and Motor Status
Color:
- Red = Fault
- Yellow = Warning
- Green = No Fault/No Warning
Flash Rate:
- Mostly ON: Actively Polled > 1 second poll rate (Any Protocol)
- Mostly OFF: Not being polled from the network.
Ch-1 and Ch-2 Status
Color Flash:
- Red, Flash Slow (1 sec ON/1 sec OFF) = connected device
missing or broken (MM or BUI)
- Green, Flash Rapid (50 ms ON/50 ms OFF) = Device discovery
- Green, Flash Mostly ON (1.45s ON, 50 ms OFF) = Device
connected and data is being exchanged properly
- Green, Flash Mostly OFF (50 ms ON/1.45s OFF) = Device
connected with no data being exchanged
ModBus Status (optional)
Color Flash:
- Green indication of tra c
Device and Motor Status
Color Flash:
