SMC Networks ISE35 Operation Manual page 8

The Pressure switch is not resistive to a lightning surge defined in CE marking. Take measures to
protect against a lightning surge at the load side.
Prevent foreign matter such as remnant of wires from entering the Pressure switch.
Take proper measures for the remnant not to enter the Pressure switch in order to prevent failure or malfunction.
Follow the specified range of the fluid and ambient temperatures.
The fluid and ambient temperatures should be 0 to 50 °C.
When operating at a temperature below 5 °C, breakage or malfunction can occur to the Pressure switch due to
freezing of condensed water in the compressed air.
Take preventive measures against freezing. Installation of an air dryer is recommended in order to remove
condensed water contained in the measured fluid.
Do not use the Pressure switch in a place where temperature suddenly changes even if it stays within the specified
range.
Do not expose the Pressure switch to heat radiation from a heat source located nearby.
It can cause malfunction.
Adjustment and Operation
Do not short-circuit the load.
The Pressure switch indicates the error status when a load is short-circuited. However, over current can damage
the Pressure switch.
Do not press the set buttons with a sharp pointed object.
It can cause damage to the set buttons.
Warm up for 20 to 30 minutes for the detection of low pressure.
The indication drifts about 1% soon after the power is on.
Maintenance
Before performing maintenance, make sure to turn off the power supply, stop supplied air, release the
residual air in the piping into the atmosphere, and verify that the pneumatic system is open to the air.
Otherwise an unexpected operation of the system component can occur.
Perform maintenance and check regularly.
Otherwise an unexpected malfunction of the system component can occur due to a malfunction of the Pressure
switch.
Perform proper functional checks and leak test after maintenance.
Stop operation when an abnormality is observed such that the Pressure switch does not work properly or there is a
leakage of fluid.
Otherwise an unexpected malfunction of the system component can occur.
Drain condensed water regularly.
The flow of condensed water to the secondary side can cause a malfunction of pneumatic equipment.
Do not use solvents such as benzene or thinner to clean the Pressure switch body.
It can damage the surface of the body and erase the indication on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully
squeezed, then wipe up the stains again with a dry cloth.
