Symptom
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. Op-
tions are 4-20 mA, 0-10 V, 0-5 V, or 1-5 V.
Destination de-
vice is not scaled
properly.
• Destination device must accept 4-20 mA sig-
nal and be scaled to properly display the sig-
nal. Check the manufacturer’s instruction
manual for how to do this.
Signal connec-
tions are improp-
erly wired.
• Double check to make sure all of the signal
connections are properly wired to all devices.
Check wiring diagrams starting on page 10.
While trying to connect field
units using PDW Manager,
none appear in the Unassoci-
ated Remote Units list.
Devices have
mismatched net-
work 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 Mod-
bus 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 dif-
fering encryption
settings.
• Encryption settings must be the same on all
devices. Use PDW Manager to verify the en-
cryption settings on all devices.
Device will not power on.
Not enough volt-
age is coming
from the power
supply.
• Devices require at least 12 VDC each in or-
der to power on. Check that the power supply
is providing enough voltage to the device and
that there are not too many devices drawing
from the supply.
Devices are im-
properly wired.
• Check to make sure all power connections
are properly wired to all devices. Check wir-
ing diagrams starting on page 10.
