4/black wire is the common port
Connect the positive power supply (P+) to the terminal 1/brown
wire of pressure switch;
Connect the negative signal module (S-) to the negative power
supply(P-);
Connect the negative signal module (S-) to the negative power
supply(P-) and then connect to the terminal 4/black wire of
pressure switch;
Connect the positive signal module (S+) to the terminal 3/blue wire
of pressure switch;
Connect the first way transistor to the terminal 2/white wire of
pressure switch;
Connect the second way transistor to the terminal 5/gray wire of
pressure switch.

A zero point adjustment should be made after installation to counter
any effects the mounting position may have on the zero setting.
When performing the adjustment, the vessel should be completely
empty, with no pressure or media on the measuring diaphragm and the
vessel exposed to atmospheric air. With unit powered, short the key-z
wire (blue) to the + power lead. hold for 5 seconds, when removed the
zero point will be adjusted.Set the zero point three weeks after
installation to ensure accuracy, and reset zero point annually.
Standard current signal transistor output: 12-30VDC,
Transistor output: 12-30VDC.
A cable with a shielded twisted-pair signal is recommended to
avoid ground loop.
The built-in transient resistance module is only effective if properly
grounded. The metal body and internal grounding terminals should
be directly grounded.
To safeguard against liquid media potentially traveling along the cable
into the terminal box, the cable should be configured in a U-shape as
shown, with the bottom of the “U” lower than the bottom of the pressure
switch.
Do not store outside.
Keep dry and dust-free.
Do not expose to the corrosive medium.
Avoid solar radiation.
Avoid mechanical shock and vibration.
Storage temperature: -40-185 (-40-85℃). ℉
Maximum relative humidity: 95%.
EMC equipment instructions 2014/30/EU.
CE mark suggests the instruments are in line with EU standards
Users need to ensure the whole equipment conform to all the
applicable standards.
Use a cleaner that is compatible with pressure switch materials
Clean carefully to ensure that the pressure port isn't damaged (e.g.
with a sharp object)
Do not directly spray electrical connection or gauge vent with water
or cleaner.
Please observe the following when cleaning:
