and then clockwise until sensor 1 trips. The milliammeter
indication changes from
≥ 3 mA to a ≤ 1 mA reading.
4. Tighten the two mounting scrrews to 15 mA, and return to 20
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.
