Caution
■
Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
■
After maintenance is complete, perform appropriate functional inspections and leak tests.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.

NOTE
○
Follow the instructions given below when designing, selecting and handling the product.
●
The instructions on design and selection
(installation, wiring, environment, adjustment, operation,
maintenance, etc.)
described below must also be followed.

Product specifications
•
Use the specified voltage.
Otherwise failure or malfunction can result.
•
Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the Pressure switch.
•
Design the product to prevent reverse current when the circuit is opened or the product is forced to operate for
operational check.
Reverse current can cause malfunction or damage to the product.
•
Input data to the Pressure switch is not deleted, even if the power supply is cut off.
(Writing time: 10,000 times, Data duration: 20 years after power off)
•
A pressure sensor of stainless steel diaphragm
is used for this switch. The pressure sensor of
this switch can be damaged by the rush inertia
of water when the drain contained in water and
air collide with the pressure sensor when
vacuum is broken after vacuum adsorption
is confirmed, and it may cause
malfunction with the pressure indication.
If there is a possibility of water or drainage
getting in, narrow the diameter of the piping
to the pressure switch, or make an orifice
in the middle of the piping shown in the
Fig. right. Extra attention is needed
When the rear piping type model is used.
