The vertical position is the recommended position for mounting and the only position for
NEMA Type 3R rating with the Weather Shield. Acceptable mounting positions are shown
in Figure 10.
Allow four inches (100 mm) around the sides and back of the actuator and eight inches
(200 mm) above and to the front of the actuator.
See dimensions in Figure 23, Figure 24, Figure 25, and Figure 26.
Detailed installation instructions for field mounting are shipped with the actuator.
CAUTION:
When removing the knockout do not damage the circuit board. Use
the top knockout position, if possible.
Check the wiring for proper connections.
NOTE:
The valve body assembly determines the complete assembly action.
All SKB/C/D62UA actuators are factory-fitted with a spring-return function. If the control
signal or power supply fails, the actuator will return to the 0% stroke position (stem fully
retracted).
The override control input (Z) has three modes of operation:
NOTE: The Z-modes have a "direct acting" factory setting.
