6.7 Transmitter board - fuses and LED’s
The transmitter board has one main fuse and some LED's to indicate status of
different supply voltages. Figure 6-4 shows the main / transmitter board layout.
If the LED close to the main fuse (“18-36V Input OK”) is lit but the other LED’s are
not, check the main fuse. If all LED’s are dark, check the 24V supply to the
instrument. If some LED’s are lit and others are not, please note which are lit and
which are not lit, and contact your local distributor as the board might have to be
serviced.
