Wiring
Connection
Connections should only be made with the power
supply turned off.
Use separate routes for the Pressure switch wiring and
any power or high voltage wiring. Otherwise, malfunction
may result due to noise.
Ensure that the FG terminal is connected to ground when
using a commercially available switch-mode power
supply. When a switch-mode power supply is connected to the product,
switching noise will be superimposed and the product specification can no
longer be met. This can be prevented by inserting a noise filter, such as a
line noise filter and ferrite core, between the switch-mode power supply and
the product, or by using a series power supply instead of the switch-mode
power supply.
Set ON and OFF point of the Pressure switch.
Operation (Hysteresis mode)
When the pressure exceeds the set value, the
Pressure switch will turn ON.
When the pressure falls below the set
value by the amount of hysteresis or
more, the Pressure switch will turn OFF.
The default setting of the output set value
is the central value between the
atmospheric pressure and the
upper limit of the rated pressure
range. If this condition, shown to the right,
is acceptable, then keep these settings.

Otherwise it can cause failure or malfunction of the system.
NOTE
•The direct current power supply to be used should be UL approved as follows:
Circuit (of Class2) which is of maximum 30 Vrms (42.4 V peak), with UL1310
Class2 power supply unit or UL1585 Class2 transformer.
•The product is a
approved product only if it has a
mark on the body.

•Provide a double interlocking system, for example a mechanical system
•Check the product regularly for proper operation
Otherwise malfunction can result, causing an accident.
The following instructions must be followed during maintenance:
•Turn off the power supply
•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance work
Otherwise an injury 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.
Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
Do not operate the product outside of the specifications.

Maintenance
How to reset the product after a power cut or forcible de-energizing
The setting of the product will be retained as it was before a power cut or
de-energizing.
The output condition is also basically recovered to that before a power cut or
de-energizing, but may change depending on the operating environment.
Therefore, check the safety of the whole installation before operating the product. If
the installation is using accurate control, wait until the product has warmed up
(approximately 10 to 15 minutes).
