Each I/O Extension Module has physical connections
for inputs (marked Ulx), which are software
configurable from within the device’s LNS® plug-in or

resistive, current, or voltage signals. You must
configure the input types properly in the software

physical connections for inputs are marked as Ulx.
IMPORTANT: Before you connect input equipment
to the extension module, refer to the installation
instructions from the equipment manufacturer.

Problem Possible Solution
Controller is powered but does not turn on.
Fuse Is Blown Disconnect power from the controller and check the fuse integrity.
Reconnect power.
Power Supply Polarity Verify that consistent polarity is maintained between all controllers and
the transformer. Ensure that the COM terminal of each controller is
connected to the same terminal on the secondary side of the
transformer. See Figure 3 and Figure 4.
I/O Extension Module cannot communicate on the subnetwork.
Absent or Incorrect Supply Voltage 1. Check power supply voltage between 24 VAC/DC ±15% and COM
pins, and ensure that it is between acceptable limits.
2. Check for tripped fuse or circuit breaker.
Overloaded Power Transformer Verify the transformer is powerful enough to supply all controllers. See
Power Wiring.
Network Not Wired Properly Check that the wire connections are correct.
Absent or Incorrect Network Termination Check the network terminations. Only the last LN-IOE4x0-0 Extension
Module must have it EOL termination set to ON. See Figure 21. When

Problem Possible Solution
Open Circuit or Short Circuit Using a voltmeter, check the voltage on the input terminal. A short circuit
has a 0 V value and an open circuit has a 5 V value.
Configuration Problem Check the configuration of the input using the controller configuration
plug-in or wizard. Refer to the online help 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. Observe the allowed voltage/current range limits for all
inputs.
Hardware output is not operating correctly.
Fuse has blown (auto reset fuse) 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 if necessary. Reconnect the power.
Output Wiring Problem Check that the wiring is correct according to this manual and according
to the peripheral device's manufacturer.
Configuration Problem Using the controller configuration wizard (LN-GPI), check the
configuration of the input. Refer to the controller's user guide for more
information.
