6 Operational check
6.1 Operational check
1. Check that the analogue input wiring meets the requirements, refer to 1.5 Wiring instructions.
2. Check that the VC-4DA is reliably plugged into the expansion interface.
3. Check that the 5V and 24V power supplies are not overloaded. Note: The power supply for the digital part of the VC-4DA comes
from the main module and is supplied via the expansion interface.
4. Check the application to ensure that the correct operating method and parameter range has been selected for the application.
5. Set the main module connected to the VC-4DA to RUN.
6.2 Fault checking
If the VC-4DA does not operate properly, check the following items.
● Check the status of the main module "ERR" indicator.
Blinking: check the connection of the expansion module and whether the configuration model of the special module is the same as the
actual connected module model.
extinguished: the expansion interface is correctly connected.
●Check the analog wiring.
Check that the wiring is accurate, refer to Figure 1-5.
●Check the status of the module's "ERR" indicator
Light up: 24Vdc power supply may be faulty, if 24Vdc power supply is normal, then VC-4DA is faulty
Extinguished: 24Vdc power supply is normal.
●Check the status of the "RUN" indicator
Blinking: The VC-4DA is operating normally
