b. Increase supply pressure noting the limitations
in the Supply Connection section and repeat the
cross-over adjustment. The actuator or valve
must not contact the stop, but must be
somewhere between the up and down stops.
Increase supply pressure sufficiently, so that a
crossover setting can be achieved with neither
cylinder output pressure equal to supply
pressure.
6. Continue calibration by performing the zero and
span adjustments.

Zero and Span Adjustments

1. Unscrew the four captive cover screws, and
remove the cover (key 41, figure 28).
2. Use tables 8 through 11 and figure 15 to select
the desired range spring and coarse span
adjustment. (The tables and figure 15 are only valid
for the standard valve travel/range spring
combinations shown.) Insert one end of the range
spring (key 150, figure 25) into the hole on the range
spring hanger (key 130) as shown in figure 15. Insert
the other end of the range spring into the hole
selected on the summing beam assembly (key 123,
figure 15).
