LED Descriptions
1. Communications Unit Status LED: Bi-color LED (red/green) displays system
status.
LED System Status
Green Blink Successful communications with a sensing module
Red Blink Interrupted communications with a sensing module. See
Troubleshooting, section.
Red Steady Diagnostic event detected. See Troubleshooting, section.
When the communications unit successfully polls a sensing module for data, the
status LED blinks green. In normal operation, the status LED blinks once for every
sensing module present, up to the maximum number of sensing modules allowed. If
communications are interrupted, the status LED blinks red. If there are more sensing
modules present than the communications unit can support, the status LED shows
the normal green blinks, followed by a red blink. See registers 40354 and 40355 to
diagnose.
2. Tx: Flashes green when the communications unit sends a data packet on the
RS-485 port.
3. Rx/Error: Bi-color LED (red/green)
LED System Status
Green Blink Flashes green when the communications unit receives a usable data packet
on the RS-485 port.
Red Blink Flashes red if the communications unit receives an unusable data packet (e.g.,
wrong baud rate or polarity; illegal function code, address, or value; failed
CRC check).
4. Power: Green when the communications unit has control power.
5. Current Sensor LEDs (8 per current sensing module):
These LEDs indicate both the direction (color) and amount (Off/On/Blink) of
current flow on each current sensor. Configure the polarity (color) of the current
measurement using the reverse switch (see DIP Switch Settings, page 5) or via the
system configuration Modbus register. The current thresholds for On and Blink are
set in the Sensor LED Blink Threshold and Sensor LED On Threshold registers. These
registers can also be used to determine LED status if the hardware is installed in a
location that makes visibility difficult.
LED System Status
Positive (+) Negative (-) Direction of Current Flow
Off Current below user configured On threshold.
Green Steady Red Steady Current in normal range.
Green Blink Red Blink Current above user configured Blink threshold (over-
range).
6. Current Sensing Module Status LED (one per current sensing module):
LED System Status
Red Steady Diagnostic event detected. See Troubleshooting, section.
Red Blink Not configured
Green Steady Normal operations, configured, online, and sensing current
Green Blink
Communicating
These LEDs can be read remotely through the Modbus registers if the hardware is
installed in a location that makes visibility difficult. Read the Sensor Unit ID registers
for each current sensing module. If the registers returns a value of 1, then the module
is active, so the user can assume the LED is green. If the register returns a value of 0,
then the module is inactive, and the user can assume the LED is red.
