Figure 27: Mainboard card fuses and LED layout
The main transmitter unit board has one main fuse and some
LEDs to indicate status of different supply voltages:
• If the LED next to the main fuse
(“18–36V Input OK”) is lit but the other LEDs are not, the
fuse must be checked.
• If all LEDs are dark, check the 24 V supply to the device.
• If some LEDs are lit and others are not, note the status of
the LEDs and contact ABB Service. The main board may
need to be replaced.
