 Solid State Pressure Switch Stroke Detection
First remove the 1/8” npt plug located in the upper right hand corner of the shuttle valve.
Replace it with a 1/8” npt X ¼” gripper fitting or other appropriate fitting. Then connect
the ¼” OD X 1/8” ID PFA tubing or other appropriate tubing to this fitting. Then connect
the other end to the same type of fitting which should be screwed into the 1/8” fnpt port
on the pressure switch.
Settings for the DP2-41N pressure switch are factory pre-set however they are as
follows:
S-PSI
D-Dual Output
D-Digital
The Out put pressures we recommend are 2psi for out put #1 and 4psi for out put #2.
Output #1 should be used for most applications. For applications where the pump is
operating at 50-60psi output #2 should be used.
