Solenoid Valve
1. Avoid energizing the solenoid valve for long periods of time. If a solenoid valve is continuously
energized for an extended period of time, the heat generated by the coil assembly may reduce
performance and life of the valve or have adverse effects on peripheral equipment. Therefore,
when it is continuously energized for an extended period of time or when the energized period
per day is longer than the de-energized period, use N.O. (normally open) type product.
When the valve is mounted onto a control panel, take measures to radiate heat in order to keep
the product temperature within the specified range.

Digital Pressure Switch for Vacuum
1. Connect a load before turning the power supply on. If the power supply is turned on with no
load, over current may flow, causing the pressure switch to break instantly.
2. Do not short circuit the load. An error is displayed when the load of the pressure switch is short
circuited, but over current may flow, causing damage to the pressure switch.
3. Do not press the setting buttons with a sharp pointed object. This may damage the setting
buttons.
4. If using the product to detect very small pressures, warm up the product for 10 to 15 minutes
first.
There will be a drift on the display of approx. 1% for 10 minutes after the power supply is turned
on.
5. Perform settings suitable for the operating conditions. Incorrect setting can cause operation
failure.
For details of each setting, refer to the Operation Manual of the pressure switch.
6. Do not touch the LED during operation. The display can vary due to static electricity.
7. For details of the ZSE30A 2-Color Display High-Precision Digital Pressure Switch other than
the above-mentioned series, please refer to the SMC website URL: http://www.smcworld.com.
