Select the input type for an analog input
You can set an analog input to either voltage (0-10 V) or current (4-20 mA) by flipping the
appropriate switches on the base input/output (I/O) board .
Procedure
1. Turn off the gas chromatograph (GC).
2. Locate and remove the base I/O board, which is in the card cage in the GC’s lower
enclosure.
3. To set analog input #1 to current, locate
SW1
on the backplane base I/O board and
push the switches up, toward the card ejector; to set the analog input to voltage,
push the switches down, away from the card ejector.
4. To set analog input #2 to current, locate
SW2
on the base I/O board and push the
switches up, toward the card ejector; to set the analog input to voltage, push the
switches down, away from the card ejector.
5. Replace the base I/O board in the card cage.
6. Close and fasten the electronic enclosure door.
7. Apply power to the GC.
