. Vacuum pressure switch
5.1
Internal Circuit and Wiring Examples
5.2.1 Vacuum pressure switch
*The FUNC terminal is connected when using the copy function.
*Refer to the Operation Manual for details on setting the ZSE10 (for ZSE10 series).
5.2.2
Pressure switch for vacuum with energy saving function
*FUNC terminal is for energy saving operation of the supply valve.
*Refer to the Operation Manual for details on setting the ZSE10 (for ZQ-ZSV series).
5.2 Handling / adjustment Precautions
1) The specified voltage must be used. Otherwise failure, malfunction or short life can result.
2) Connect a load before turning the power supply on. If the power supply is turned on with no
load connected to the pressure switch, over current may occur, causing the product to break
instantly.
3) 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.
4) Do not press the setting buttons with a sharp pointed object. This may damage the setting
buttons.
5) 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 approximately 1% for 10 minutes after the power
supply is turned on.
6) Perform settings suitable for the operating conditions. Incorrect setting can cause operation
failure. For settings, refer to the Operation Manual of the pressure switch.
7) Do not touch the LED during operation. The display can vary due to static electricity.
8) If a commercially available switching power supply is used, be sure to ground the frame
ground (FG) terminal.
