Service
The 2020ADC 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 unless as directed otherwise by Customer service.
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 13 .
• Check for presence and quality of input signals.
• Verify that source equipment is operating correctly.
• Check cable connections.
Figure 13. Location of Module Fuse
Refer to Figure 6 for the location of PWR LED and Table 3 on page 15 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.
