Caution
Caution indicates a hazard with a low level of risk which, if
not avoided, could result in minor or moderate injury.
Warning
Warning indicates a hazard with a medium level of risk
which, if not avoided, could result in death or serious injury.
Danger
Danger indicates a hazard with a high level of risk which, if
not avoided, will result in death or serious injury.
Warning
•
Always ensure compliance with relevant safety laws and
standards.
•
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.
•
This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted
or radiated disturbances.
Otherwise electric shock, malfunction or product damage can result.

2 Specifications
2.1 General specifications
∗
1: Value without digital filter (at 0 ms).
∗
2: If the applied pressure fluctuates around the set value, the hysteresis must be
set to a value more than the amount of fluctuation or chattering will occur.
∗
3: This setting is only available for models with the units selection function. Only
MPa or kPa is available for models without this function.
∗
4: The response time indicates when the set value is 90% in relation to the step
input.

4 Installation
4.1 Installation
Warning
Do not install the product unless the safety instructions have been read
and understood.
4.1.1 Mounting
•
Mount the optional bracket and panel mount adapter to the pressure
switch.
•
When the pressure switch is to be mounted in a place where water
and dust splashes occur, insert a tube into the atmospheric vent port
of the pressure switch (refer to “Tube attachment”).
4.1.2 Mounting with bracket
•
Mount the bracket to the body with mounting screws (Self tapping
screws: Nominal size 3 x 8L (2 pcs)), then set the body to the
specified position.
∗
: Tighten the bracket mounting screws to a torque of 0.5 ±0.05 N•m.
Self-tapping screws are used and should not be re-used several times.
•
Rear Piping
•
Bracket A (Part No.: ZS-46-A1)
•
Bottom Piping
•
Bracket C (Part No.: ZS-46-E)
4.1.3 Mounting with panel mount adapter
•
Rear Piping
•
Mount part (a) to the front of the body and fix it. Then insert the body
with (a) into the panel until (a) comes into contact with the panel front
surface. Next, mount part (b) to the body from the rear and insert it
until (b) comes into contact with the panel.
•
Panel mount adapter (Part No.: ZS-46-B)
Panel mount a Front protective cover (Part No.: ZS-46-D)
∗
: The panel mount adapter can be rotated through 90 degrees for mounting.
