Electrical Connections
Since the Rev-counter is self powered, only 2 electrical connections are re-
quired. These connections are made utilizing 2 of the 3 terminal blocks,
located at the rear of the unit. Refer to the procedures below when connecting
the Rev-counter to the Pickup.
Connect the BARE and the WHITE wire to the #1 GND terminal.
Connect the BLACK wire to the #3 INP terminal.
Installation
The Rev-counter should be mounted so that it can be seen by the operator of
the spreader while spreading is taking place.
The sensor should be as close to the timing disc as possible without rubbing—up to
¼” away. If sensor is too close, it will read all the time.
Switches are set correctly by Newton Crouch Inc. The correct positions are indi-
cated by the diagram below. Drawing 1
