For DVP04TC-s/ DVP04PT-s and DTE its is possible to configure the input channels for different sensor types and also disable the unused channels. This will prevent flashing error LED when no other errors are present.

  • For DVP04TC-s and DVP04PT-S we use Control Register 1 (CR#1):

Example 1: For DVP04TC-S set CH1 for J-type sensor, CH2 K-type sensor, CH3 T-type sensor and disable CH4.

CH1 = (b2-b0) = (0, 0, 0) for J-type

CH2 = (b5-b3) = (0, 0, 1) for K-type

CH3 = (b6-b8) = (1, 0, 0) for T-type

CH4 = (b11-b9) = (1, 1, 1) to disable channel

Example 2: For DVP04PT-S set CH1 for PT100 sensor, CH2 NI100 sensor and disable CH3-4.

CH1 = (b3-b0) = (0, 0, 0, 0) for PT100

CH2 = (b7-b4) = (0, 0, 0, 1) for NI100

CH3 = (b11-b8) = (1, 1, 1, 1) to disable channel

CH4 = (b15-b12) = (1, 1, 1, 1) to disable channel

  • For DTE we use Function Address 10F6H :

Example 3: For DTE set CH1 – CH4 Enable, CH5 -CH7 Disable & CH8 Enable:

CH1(b0) = (0) Enable

CH2(b1) = (0) Enable

CH3(b2) = (0) Enable

CH4(b3) = (0) Enable

CH5(b4) = (1) Disable

CH6(b5) = (1) Disable

CH7(b6) = (1) Disable

CH8(b7) = (0) Enable

Write data 01110000 0r 70H to Function Address 10F6H
