Figure 3-10. Connecting Piping for Closed Tank,
Condensing Atmosphere Level Measurement
The TEST terminals have the same four to 20-milliampere sig-
nal as the PWR/OUTPUT terminals. Loosen the - (negative)
TEST terminal jumper screw ½-turn for calibration or testing.
Signal wiring should be shielded. Use twisted pairs for best
results. Connect the shield at the ground terminal inside the
electronics housing (Fig. 2-4) or at the receiver.
NOTE: Connect the shield at one end only. Connecting the shield at
both ends may result in a ground loop condition.

DIGITAL MODE

In the digital mode of operation there is no four to
20-milliampere signal. The transmitter draws less than four
milliamperes to maintain operation (Fig. 2-5).
NOTE: Refer to the Field Bus I/O Module (IMFBS01) Instruction
for wiring practices and output update times.
