Setpoints are changed by means of the setpoint adjusters. The
GP-S single switch has one adjuster and the GP-A adjustable
deadband and GP-D dual switch each have two adjusters. On
switches with two adjusters, the one on the left is referred to as
“A” and the right one is referred to as “B”; see illustration.
Setpoints can be adjusted from 20 to 100 percent of full range
on increasing pressure.
