Switch Calibration Procedure
Never perform switch calibration procedure while area is known to be
hazardous.
For Intrinsically Safe models, unit must be wired in accordance to Control
Drawing
S-K094/094A. Or, for standard explosion-proof models:
Calibration may be performed using a Volt-Ohm meter by using the Ohm setting
across COM and NO. When switch is active, the meter will read <0.5 Ohms, or
the Diode setting may used simply to indicate continuity.
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 un-
known, or permanent damage may occur.
Step 1: With valve in the CLOSED position. Push down and slide target magnet
#1 until SW1 activates. Release the target magnet to lock the position.
Step 2: Rotate valve to the OPEN position. Push down and slide target magnet
#3 until SW3 activates. Release the target magnet to lock the position.
Step 3: Cycle valve CLOSED and OPEN several times to insure switches will
maintain calibration.
For Reverse Acting Actuators:
Step 1: Loosen the 6-32 x .25 set screw on the target disk and lift up on the
target disk enought to disengage the locator pin.
Step 2: While holding the shaft from turning, rotate the target disk 90 Degrees
counter-clockwise. Push down on the target disk until the locator pin engages.
Step 3: Tighten the set screw to 40 in/oz.
Step 4: Perform steps 1-3 above.
Note: For other valve configurations the target disk can be moved in 90 degree
increments to adapt to the application. L4 units are adjusted per application.
