Service
The 2020DAC modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser-
viced in the field.
Troubleshooting
If your module is not operating correctly, proceed as follows:
■ Check frame and module power. If power is not present, check the fuse
on the +24 V input to the module as illustrated in
Figure 12 .
■ Check for presence and quality of input signals.
■ Verify that source equipment is operating correctly.
■ Check cable connections.
Figure 12. Location of Module Fuse
Refer to Figure 6 on page 6 for the location of PWR LED and Table 4 on
page 7 for proper LED indications.
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
