If the Network Status LED on your VAT Control Unit is flashing red, it indicates a timeout. This is often caused by I/O connections being in a timeout state. To resolve this, you should reestablish the I/O connections.
Why VAT Control Unit does either not respond or respond in an unexpected way to DeviceNet® commands?
If the VAT Control Unit controller is not responding or is responding unexpectedly to DeviceNet® commands, it may be due to an incorrect configuration. You should send a FACTORY RESET and redo the complete configuration. Consult «Explicit messaging control commands, FACTORY RESET» and «Setup procedure, DeviceNet® configuration» for details.
Why VAT Control Unit controller does not respond to DeviceNet® commands?
If the VAT Control Unit controller does not respond to DeviceNet® commands, check that the node number and baud rate are correct. Then proceed according to «Setup procedure, DeviceNet® CONFIGURATION».
Why is the Module Status LED flashing green on my VAT Control Unit?
If the Module Status LED is flashing green on your VAT Control Unit, the controller requires commissioning because of a missing, incomplete, or incorrect configuration.
How to fix no dots lighted on display of VAT Control Unit?
If there are no dots lighted on the display of your VAT Control Unit, connect the valve to the power supply according to «Electrical connection» and ensure that the power supply is working.
What to do if Network Status LED is off (Device is not on line) on VAT Control Unit?
If the Network Status LED is off (device is not online) on your VAT Control Unit, connect the valve to DeviceNet® according to «DeviceNet? connection» and ensure that power is provided.
What to do if Module Status LED is off on VAT Control Unit?
If the Module Status LED is off on your VAT Control Unit, connect the valve to DeviceNet® according to «DeviceNet? connection» and ensure that power is provided.
