Setting
(se also “Wiring”)
KP 1 (auto reset), KP 2, KP 5, KP 7W and KP 7B KP 1 (manual reset ONLY)
1. Adjust range spindle to desired 1. Adjust range spindle to desired
HIGH SET POINT (HSP) LOW SET POINT (LSP)
2. Adjust differential spindle to 2. DIFFERENTIAL is fixed.
desired DIFFERENTIAL (DIFF.) Value printed on scale plate
Note:
KP 5 (manual reset) and KP 7B have fixed diff.
Value printed on scale plate.
HIGH SET POINT minus DIFFERENTIAL equals LOW SET POINT LOW SET POINT plus DIFFERENTIAL equals HIGH SET POINT
Example: Example:
HSP – DIFF. = LSP LSP + DIFF. = HSP
30 psig – 20 psi = 10 psig 12 psig + 10 psi = 22 psig
(2.1 bar) (1.4 bar) (0.7 bar) (0.8 bar) (0.7 bar) (1.5 bar)
If terminals 1-4 are used: CUT-IN = HSP
CUT-OUT = LSP
If terminals 1-2 are used: CUT-IN = LSP
CUT-OUT = HSP
