Table 1 describes the normal and safe states of DVC6200 SIS for a DETT configuration. The digital valve controller may be operated with one of the following controlsignals:D 0 24 VDC: Normal operation is with a 24 VDC signal applied to the digital valvecontroller.

9 A shut down command is issued by interrupting the loop or taking thevoltage signal to 1 VDC or 4 20 mA: Normal operation is with a 20 mA current loop signal to the digital valvecontroller. A shut down command is issued by taking the current signal to 4 mA(nominal). If a loop powered LCP100/LCP200 is attached, the shut down command isissued by taking the current signal to 8 mA (nominal).Table 1.
