Contact load ratings
Load Option A
CUT-OUT on pressure drop
Wire terminals 1-4:
CUT-IN = High Set Point (HSP)
see “Setting”
CUT-OUT = Low Set Point (LSP)
see “Setting”
Load Option B
CUT-OUT on pressure rise
Wire terminals 1-2:
CUT-IN = Low Set Point (LSP)
see “Setting”
CUT-OUT = High Set Point (HSP)
see “Setting”
Example:
CUT-IN = 30 psig
CUT-OUT = 10 psig
This means :
CUT-IN = HSP = 30 psig
CUT-OUT = LSP = 10 psig
Example:
CUT-IN = 250 psig
CUT-OUT = 350 psig
This means :
CUT-IN = LSP = 250 psig
CUT-OUT = HSP = 350 psig
