Troubleshooting
The following list contains possible problems you may encounter and some solutions.
Most of the problems involving the UNIK Field Transmitter can be classified as trans-
mission/reception malfunctions usually caused by a dead or improperly connected bat-
tery. Other common causes of malfunction could be a dirty optical connector and poor
wire connections.
These problems are easy to fix. If you experience transmission/reception problems, try
using a Control Module that operates properly to determine if it is the Field Transmitter
or Control Module that is the source of the
problem.
