Diagnostic Messages, Codes and Details
The DVC2000 digital valve controller is constantly diagnosing itself for abnormal conditions while powered‐up. The
following messages will appear on the local user interface if a fault condition exists (identified on the default screen by
the alert symbol ! ).
SWITCH 1 ???
SWITCH 2 ???—The alert symbol in conjunction with the above text indicates that limit switch circuit 1 is not powered,
or at least one of the switches is enabled. In order for either of the switches to work, switch circuit 1 must be powered.
Switch 2 cannot be used alone. To eliminate the alert symbol, you can either apply 5 to 30 VDC to switch circuit 1 or
disable both switches from DETAILED SETUP.
