Explanation of the diagram in the previous page

A - Reading reaches (Hi SET - ½ HI HYS), the Hi-Set relay

remains inactivated.

B - Reading reaches above High Setpoint but below (Hi SET +

½ Hi HYS), Hi-Set relay remains inactivated.

C - Reading reaches between (Hi SET - ½ Hi HYS), the Hi-Set

relay remains inactivated.

D - Reading reaches above (Hi SET + ½ Hi HYS), and the Hi-

Set relay is activated.

E - The Hi-Set relay is inactivated only when the reading falls

below (Hi SET - ½ Hi HYS).

F - Reading reaches between (Lo SET - ½ Lo HYS), the Lo-

Set relay remains inactivated.

G - Reading reaches below (Lo SET - ½ Lo HYS), the Lo-Set

relay is activated.

H - The Lo-Set relay remains activated until the reading goes

above the (Lo SET + ½ Lo HYS)

F
