Touch & Tune switch setting
All adjustments assume you are looking down on the top of the
sensors. The edge of the cam metal strip will be at the edge of the
sensor target 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 so that
the metal activation strip is centered on the bottom sensor target
and the top cam is 180° from the bottom cam.
2. Lift up bottom cam and rotate counterclockwise until the green
LED is lit and remains lit when the cam is released, then rotate
clockwise until the green LED goes off and remains out when the
cam is released.
3. Move valve to the open position. Push down top cam and rotate
counterclockwise until the red LED goes off. Release cam.
Valve closed to open in clockwise rotation (Fig. 2)
1. With the valve in the closed position, set the bottom cam so that
the metal activation strip is centered on the bottom sensor target
and the top cam is 180° from the bottom cam.
2. Lift up bottom cam and rotate clockwise until the green LED
is lit and remains lit when the cam is released, then rotate
counterclockwise until the green LED goes off and remains out
when the cam is released.
3. Move valve to the open position. Push down top cam and rotate
clockwise until the red LED goes off. Release cam.
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.
Bench test procedure
Use StoneL Light Read Tester or use a 24 VDC power supply. No series
load resistor required.

Caution:
To prevent ignition of hazardous atmospheres,
replace cover before energizing the electrical circuits. Keep
cover tightly closed within operation.
