I Valve Closed to Open in counter-clockwise rotation,
Fig. 4
1. With the valve in the "Closed" position, set the bot-
tom cam so that the metal activation strip is cen-
tered on the bottom sensor target and the top cam
is 180° from the bottom cam.
2. Lift up bottom cam and rotate counter-clockwise
until the green LED comes "on" and remains "on"
when the cam is released, then rotate clockwise
until the green LED just goes "off" and remains out
when the cam is released.
3. Move valve to the "Open" position. Push down top
cam and rotate counter-clockwise until the red LED
just goes "off". Release cam.
II Valve Closed to Open in clockwise rotation, Fig. 5
1. With the valve in the "Closed" position, set the bot-
tom cam so that the metal activation strip is cen-
tered 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 comes "on" and remains "on" when the
cam is released, then rotate counter-clockwise until
the green LED just 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 just goes
"off". Release cam.
Notes:
1. With the valve in the Closed position, the red LED is
"on" 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 cur-
rent).
2. When the valve is in the Open position, the green
LED is "on" 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 LED's will be "on" and neither
sensor will be active.
Type A
I. Valve Closed to Open in counter-clockwise rotation,
Fig. 10
1. With the valve in the "Closed" position, set the bot-
tom cam so that the metal activation strip is cen-
tered on the bottom sensor target and the top cam
is 90° from the bottom cam. Connect power supply
and ammeter to the bottom switch.
2. Lift up bottom cam and rotate counter-clockwise
until the ammeter reads >3 mA, then rotate clock-
wise until the ammeter reads <1 mA. Release the
cam.
3. Move valve to the "Open" position. Connect power
supply and ammeter to the top switch. Push down
top cam and rotate clockwise until the ammeter
reads >3 mA then counterclockwise until the amme-
ter reads <1 mA. Release cam.
II. Valve Closed to Open in clockwise rotation,
Fig. 11
1. With the valve in the "Closed" position, set the top
cam so that the metal activation strip is centered on
the top sensor target and the bottom cam is 90°
from the top cam. Connect power supply and
ammeter to the top switch.
2. Push down top cam and rotate clockwise until the
ammeter reads >3 mA, then rotate counter-clock-
wise until the ammeter reads <1 mA. Release the
cam.
3. Move valve to the "Open" position. Connect power
supply and ammeter to the bottom switch. Lift up
bottom cam and rotate clockwise until the ammeter
reads >3 mA, then rotate counter-clockwise until the
ammeter reads <1 mA. Release the cam.
Type N
Valve Closed to Open in counter-clockwise rotation,
Fig. 12
1. With the valve in the "Closed" position, set the bot-
tom cam so that the metal activation strip is cen-
tered on the bottom sensor target and the top cam
is 180° from the bottom cam. Connect power supply
and ammeter to the bottom switch.
2. Lift up bottom cam and rotate counter-clockwise
until the ammeter reads >3 mA, then rotate clock-
wise until the ammeter reads <1 mA. Release the
cam.
3. Move valve to the "Open" position. Connect power
supply and ammeter to the top switch. Push down
top cam and rotate counter-clockwise until the
ammeter reads <1 mA. Release cam.
