Possible Cause
Corrective Action
Destination device reads out
of range, zero, or incorrect.
Wireless device
has mismatched
input type.
• Make sure that input type on the device is
correct for the analog input being used.
Options are 4-20 mA, 0-10 V, 0-5 V, or 1-5 V.
Destination
device is not
scaled properly.
• Destination device must accept 4-20 mA
signal and be scaled to properly display the
signal. Check the manufacturer’s instruction
manual for how to do this.

Devices have
mismatched
network IDs.
• Devices will not connect if they do not have
the same network ID. Verify that all devices
share the same network ID.
Multiple field units
have same
Modbus address.
• If multiple field units share the same Modbus
address it will cause a conflict. Verify that all
field units have unique Modbus addresses.
Devices have
differing
encryption
settings.
• Encryption settings must be the same on all
devices. Use WR Manager to verify the
encryption settings on all devices.
Device will not power on.
Not enough
voltage is coming
from the power
supply.
• Devices require at least 12 VDC each in
order to power on. Check that the power
supply is providing enough voltage to the
