INSTALLATION - SETTING MECHANICAL SWITCHES (Switch Types 1, 3 and 4)
1. Remove VPT cover from the housing by loosening the screws holding the
housing and cover assembly together.
2. Move the valve or valve actuator assembly to a position where one or more of the
switches will be required to operate noting the direction of VPT shaft rotation.
3. Determine which switch is to be set and lift or depress the corresponding cam as
required. Rotate the cam in the direction of shaft rotation until the cam engages
the switch and closes the normally open contact for SPDT and DPDT switches.
4. Repeat Steps 2 and 3 until all of the switches are set.
5. Replace the VPT cover and tighten the screws. To ensure that the shaft alignment
is secured, bring all of the screws in contact with the cover and then tighten them in
stages moving from one screw to its diagonal counterpart.
INSTALLATION - SETTING TTL MAGNETIC SWITCHES
NOTE: To properly set switches, an ohm meter or equivalent devices will be required.
1. Remove VPT cover from the housing by loosening the screws holding the housing
and cover assembly together.
2. Move the valve or valve actuator assembly to a position where one or more of the
switches will be required to operate noting the direction of VPT shaft rotation.
3. Determine which switch is to be set and lift or depress the corresponding cam as
required. Using the arrow only as a guide, rotate the cam in the direction of shaft
rotation until the circle on the cam and the arrow on the switch are aligned with
each other. IMPORTANT - To be sure the normally open contact is now closed,
you must use an ohm meter or equivalent device to check the setting.
4. Repeat Steps 2 and 3 until all of the switches are set.
5. Replace the VPT cover and tighten the screws. To ensure that the shaft alignment
is secured, bring all of the screws in contact with the cover and then tighten them
in stages moving from one screw to its diagonal counterpart.
(Switch Types 2, T and B)
INSTALLATION - SETTING INDUCTIVE SENSORS (Switch Types 8, K and M)
1. Remove VPT cover from the housing by loosening the screws holding the housing
and cover assembly together.
2. Move the valve or valve actuator assembly to a position where one or more of the
sensors will be required to operate noting the direction of VPT shaft rotation.
3. Determine which switch is to be set and lift or depress the corresponding cam as
required. Using the target area only as a guide, rotate the cam in the direction of
shaft rotation until the pin on the cam and the target area on the sensor are aligned
with each other. If the sensor has an LED, it should light now.
4. Repeat Steps 2 and 3 until all of the sensors are set.
5. Replace the VPT cover and tighten the screws. To ensure that the shaft alignment
is secured, bring all of the screws in contact with the cover and then tighten them in
stages moving from one screw
NOTE: To properly set sensors, an appropriate sensor tester will be required.
IMPORTANT - To be
sure the sensor is now actuated you must use an appropriate sensor tester.
to its diagonal counterpart.
WARNING: To prevent the possibility of personal injury or property damage, turn off electrical power
before inspection, adjustment, or removal of the valve position transmitter.
