■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
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) or less, with UL1310 Class2 power supply unit or
UL1585 Class2 transformer.
The Pressure switch is a UL approved product only if it has a
The Pressure switch designed only for the measurement of compressed air (including vacuums).
The compressed air must contain no chemicals, synthetic oil with organic solvent, salts nor corrosive gas.
Air that includes these substances can cause damage or malfunction of the Pressure switch.
Verify the specifications carefully before use.
Do not use the Pressure switch for compressed air containing plenty of condensed water.
Otherwise it can cause malfunction of the Pressure switch.
When measuring the air with condensed water, install an air dryer / drain catch before a filter, and drain the
condensed water regularly.
Improper draining of condensed water allows the flow with condensed water into the secondary side and causes
malfunction of pneumatic equipment.
Use of the filter with an auto drain is recommended when the draining is difficult to perform.
Compressed air quality should comply with JIS B 8392-1 1.1.2 through 1.6.2:2003.
Use the specified voltage.
Operation with a voltage outside of specifications can cause malfunction or damage of the Pressure switch.
Insufficient voltage may not drive a load due to a voltage drop inside the Pressure switch.
Verify the operating voltage of the load before use.
Use the Pressure switch within the specified ranges of the measurement flow rate and operating
pressure.
Otherwise it can cause damage to the Pressure switch and abnormal measurement.
Do not apply a constant pressure higher than 0.5 MPa to vacuum Pressure switch. (Specifications: -101 to 101 kPa)
Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the Pressure switch.
Input data to the Pressure switch is not erased after the power is off.
Reserve a space for maintenance.
Consider a space for maintenance when designing whole system.
