CAUTION:
Disconnect power supply before wiring connections are made or service to avoid possible electrical shock
or damage to equipment. Do never touch live parts with your ngers or with any tool.
Wiring
All wiring should conform
to the National Electrical Code
and local regulations.
CAUTION:
Use terminal screws furnished
in the contact block.
Use tightening torque 20 lb.
in (2.3 Nm).
Use copper wire only.
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

on pressure drop
Note:
Note:
KP 1, man. reset is possible only
after a pressure rise of
10 psi (0.7 bar). KP 5 and KP 7B,
man. reset is possible only after a
pressure drop of respectively
43 psi (3.0 bar) and 58 psi (4.0 bar).
Note:
KP 1, KP 5 and KP 7B with
man. reset:
Push manual reset knob during
manual tripping.
