165 ECLYPSE APEX
Symptom Possible Cause Solution
The STATUS LED is
blinking
The device has auto-
diagnosed a fault
condition
See LED Fault Condition Interpretation for ECB Devices for a list of fault
codes.
Controller
communicates well over
a short network BACnet
MS/TP network, but
does not communicate
on large network
Network length
Check that the total wire length does not exceed the specifications of the
Network Guide. See
Data Bus Physical Specifications and Cable
Requirements .
Wire type
Check that the wire type agrees with the specification of the Network Guide:
See
Data Bus Physical Specifications and Cable Requirements .
Network wiring
problem
Double check that the wire connections are correct.
Absent or incorrect
network termination
Check the network termination(s). Incorrect or broken termination(s) will
make the communication integrity dependent upon a controller's position on
the network.
Number of controllers
on network segment
exceeded The number of controllers on a channel should never exceed 50. Use a
router or a repeater: See
Data Bus Segment MAC Address Range for BACnet
MS/TP Devices .
Max Master parameter
Configure the maximum number of master device on the MS/TP network in
all devices to the controller's highest MAC address used on the MS/TP trunk.
See
BACnet MS/TP Data Bus Token-Passing Overview .
Hardware input is not
reading the correct
value
Input wiring problem
Check that the wiring is correct according to the module's hardware
installation manual and according to the peripheral device's manufacturer
recommendations.
Open circuit or short
circuit
Using a voltmeter, check the voltage on the input terminal. For example, for
a digital input, a short circuit shows approximately 0V and an open circuit
shows approximately 5V. Correct wiring if at fault.
Configuration problem
Using the controller configuration wizard, check the configuration of the
input. Refer to the controller's user guide for more information.
Over-voltage or over-
current at an input
An over-voltage or over-current at one input can affect the reading of other
inputs. Respect the allowed voltage / current range limits of all inputs.
Consult the appropriate datasheet for controller input range limits.
Hardware output is not
operating correctly
Fuse has blown (Auto
reset fuse, for 24V
controllers) Disconnect the power and outputs terminals. Then wait a few seconds to
allow the auto-reset fuse to cool down. Check the power supply and the
output wiring. Reconnect the power.
Output wiring problem
Check that the wiring is correct according to the module's hardware
installation manual and according to the peripheral device's manufacturer.
Configuration problem
With EC- gfx Program, check the configuration of the output; for example, is it
enabled? Refer to the EC- gfx Program User Guide for more information.
0-10V output, 24VAC
powered actuator is
not moving
Check the polarity of the 24VAC power supply connected to the actuator
while connected to the controller. Reverse the 24VAC wire if necessary.

ECB Device LED In-
terpretation
Description Solution
RX LED not blinking
Data is not being received from the BACnet
MS/TP data bus.
If there is no communication, see Troubleshooting
Controller Symptoms .
TX LED not blinking
Data is not being transmitted onto the BACnet
MS/TP data bus.
POWER constant on
Power is available at the device. However, this
does not mean that the quality of supplied
power is good. See Power Supply
Requirements for 24VAC-Powered Controllers
on page 163.
If not lit, see Power Supply Requirements for
24VAC-Powered Controllers for the power
requirements.
