6 Operational check
6.1 Routine check
1. Check that the analogue input wiring meets the requirements (refer to 1.5 Wiring instructions).
2. Check that the VC-4PT expansion module is reliably plugged into the expansion connector.
3. Check that the 5V power supply is not overloaded. Note: The power supply for the digital part of the VC-4PT comes from
the main module and is provided 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 VC1 main module to which the module is connected to a RUN state.
6.2 Fault check
If the VC-4PT does not operate properly, check the following items.
● Check the status of the main module "ERR" indicator.
Blinking: check whether the expansion module is connected 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
If the 24Vdc power supply is normal, then the VC-4PT is faulty.
Off: 24Vdc power supply is normal.
Check the status of the "RUN" indicator
Blinking: The VC-4PT is operating normally.
