南宫莫尘If a 120Vac source is used, an appropriately sized resistor must be used in series to limit current to a maximum of 15 Amperes when circuit rating is unknown, or permanent damage may occur.
Step 1: With valve in the CLOSED position, disengage the BOTTOM cam from the splined Hub and rotate Clockwise until SW1 activates. Release cam to re-engage splined Hub.
Step 2: Rotate valve to the OPEN position. Disengage the TOP cam from the splined Hub and rotate Counter-clockwise until SW2 activates. Release cam to re-engage the splined Hub.
Step 3: Cycle valve CLOSED and OPEN several times to insure switches will maintain calibration.
For Reverse Acting actuators:
Step 1: With valve in the CLOSED position, disengage the TOP cam from the splined Hub and rotate Counter-clockwise until SW2 activates. Release cam to re-engage the splined Hub.
Step 2: Rotate valve to the OPEN position. Disengage the BOTTOM cam from the splined Hub and rotate Clockwise until SW1 activates. Release cam to re-engage the splined Hub.
Repeat Step 3 above.
*When using the (4) and (6) switch options, use the same calibration steps as above for the switches you determine to indicate OPEN and which indicate CLOSED.
**Switches may also be set at midpoint, or any point, of travel for Dribble Control, or any other logic necessary for the application.
