Internal Jumpers And Switches

The input to the DVC6200 SIS is determined by the PtPt/MultiDrop switch on the printed wiring board.

The DVC6200 SIS also has a pair of “Output” terminals that can either function as a position transmitter or a discrete

switch. Electronic configuration of the output circuit requires the proper setting of a DIP switch on the DVC6200’s

printed wiring board. Additionally, the functional operation of the output circuit must be configured with the user

interface.

SELECTION

The DVC6200 SIS has an analog shutdown circuit built into the electronics construction. This circuit enables the

DVC6200 SIS to perform the safety function through electronics hardware, independent from the device firmware.

This function is controlled by two DIP switches:

One switch enables or disables the hardware shutdown feature.

The other switch to choose either to deenergizetotrip (labeled “Trip Current Low (DETT)”) or energizetotrip

(labeled “Trip Current High (ETT)”).

The cutoff point is 12 mA +/ 5% and is not configurable. DETT is the standard configuration for direct acting

applications. Energizetotrip (ETT) is the standard configuration for reverse acting applications.

Refer to the DVC6200 SIS instruction manual for additional details on the settings of the selection switches.

Write Protection

There are two Write Protection states for the DVC6200 SIS: Not Protected or Protected. Protected prevents

configuration and calibration changes to the instrument. The default setting is Not Protected. Protection is controlled

under software control. Write Protection can be enabled remotely. However, to disable Write Protection to Not

Protected, you must have physical access to the instrument. The procedure will require you to press a button inside

the terminal box when directed by the software as a security measure.
