Note
Total loop impedance must be sufficient to keep loop current below maximum rating.
Procedure
1.
Ensure the power source and connecting cable meet the requirements outlined
previously.
2.
Turn off the transmitter and pulse output power sources.
3.
Run the power cable to the transmitter.
4.
Connect - DC to terminal 3.
5.
C DC to terminal 4.
Internal
When the pulse switch is set to internal, the pulse loop will be powered from the
transmitter. Supply voltage from the transmitter can be up to 12 VDC. Refer to
and connect the transmitter directly to the counter. Internal pulse power can only be used
with an electronic totalizer or counter and cannot be used with an electromechanical
counter.
