Three easy steps to check a system with an EMO-1005, a pickup and wiring in between.
1. With a paper clip, touch between pin 2 to pin 4 (or pin 3, if used) via the 15 pin connector
on the back of the EMO-1005, wiggle the clip and see if there are any pulses registered on the display.
If so, the EMO-1005 is working fine, go to step 2. If no pulses are registered, please call AW company
for technical assistance or return authorization.
2. Disconnect the pickup from its Amphenol connector, and use the paper clip between the A and C
holes on the connector. If wiring is OK, pulses should be registered on the EMO-1005 display. Go to
step 3. If no pulses, check the wiring from the connector to the EMO-1005.
3. Unscrew the pickup, and replace the connector. With a screw driver or any other ferrous
material move it in front of the pickup sensor, no more than 1/8" from the sensor. If pulses are
registered on the EMO-1005, check if the flowmeter is turning and if the pickup is screwed all the way
into the flowmeter. If no pulses are registered on the EMO-1005, the pickup is probably defective.
