mA to verify that the cam trips the sensor, and the milliammeter
reading changes from a

≥ 3 mA to a ≤ 1 mA.

5. Remove the milliammeter and power supply leads from termianl

positions 6 and 7, and attach them to termianl positions 3 and 4.

6. Adjust the input signal to 4 mA and verify that the cam trips the

sensor and the milliammeter reading changes from a

≥ 3 mA to

a

≤ 1 mA reading.

7. If the milliammeter reading does not change, and continues to

show an

≥ 3 mA reading, loosen the cam assembly mounting

screws and adjust the cam as necessary.

8. Repeat the adjustment and set procedure until you can supply a

4 mA or a 20 mA signal and have the appropriate sensor trip.
