Touch & Tune switch setting
All adjustments assume you are looking down on the top of the
sensor module. The magnet in the cam will be centered on the sensor
when activation occurs. When the cam is released be sure it slides fully
onto the spline. One spline tooth setting is 4 1/2°.
Valve closed to open in counterclockwise rotation (Fig. 1)
1. With the valve in the closed position, set the bottom cam by lifting
up off the splined collar rotating so that the magnet is centered on
the bottom sensor and the top cam is 90° from the bottom cam.
2. At this time the red LED will be lit and green LED out.
3. Move valve counterclockwise to the open position. Green LED will
be lit and red LED will be out. If the red LED is lit, push down top
cam and rotate until magnet in the top cam is centered on the
top sensor and the red LED goes out. Cam adjustments are now
completed.
Valve closed to open in clockwise rotation (Fig. 2)
1. With the valve in the closed position, set the bottom cam by lifting
up off the splined collar rotating so that the magnet is centered on
the bottom sensor and the top cam is 90° from the bottom cam.
2. At this time the red LED will be lit and green LED out.
3. Move valve clockwise to the open position. Green LED will be
lit and red LED will be out. If the red LED is lit, push down top
cam and rotate until magnet in the top cam is centered on the
top sensor and the red LED goes out. Cam adjustments are now
completed.
Notes
1. With the valve in the closed position, the red LED is lit and the
bottom sensor is active (i.e. drawing less than 1.0 mA of current),
while the top sensor is inactive (i.e. drawing greater than 3.0 mA of
current).
2. When the valve is in the open position, the green LED is lit and the
top sensor is active while the bottom sensor is inactive.
3. During valve transition from closed to open or open to closed
both LEDs will be lit and neither sensor will be active.
Caution:
To prevent ignition of hazardous atmospheres,
replace cover before energizing the electrical circuits. Keep
cover tightly closed within operation.
