USE: Water pump
protection (system: pump+pressure switch+pressure tank)
- Fire-fighting system. OPERATION: The switch
stops the pump (con-tact opening) when the pressure
decreases and overcomes the pre-set stop pressure value
(stop pressure): to power the pump anew (contact closing)
it is necessary to push the reset button. CONSTRUCTION CHARATERISTICS: TERMINALS: M4x8
screws with pressure dice. STANDARD
ELETRIC CONTACTS - NO (normally open) DOUBLE CONTACT:
brass alloy with Ag-Ni surfacing. MEMBRANE: texile
integrated NBR rubber. STANDERD CONNECTION:
female 1/4” Gas.
IMPORTANT:
The water column (h), LP3 exit side, must not
be higher than the pre-set stop pressure. In case
of standard setting (0,1 bar) the water column
- exit side - must be lower than 1 mt
(h<1 mt).
