Setting Limit Switch LSB • Rotate the handwheel to locate the valve in a mid-position. • Rotate the handwheel counter-clockwise to position the valve at the desired LSB tripping point, and back-off (clockwise) four (4) full turns. • Apply the setting instructions as outlined in Section 7 to set limit switch LSB using Spindle K, Pointer L and Point F. -
Page 15: Storage
14. STORAGE The following are short-term storage instructions (Less than 12 Months): • Actuators should be stored in a clean, dry, protected environment, free from excessive vibration and rapid temperature changes. If actuators must be stored outdoors, they must be stored high enough off the ground to prevent being immersed in water or buried in snow. -
