SMC’s ZSE30A(F)/ISE30A series two‑color display high‑precision digital pressure switches are widely adopted in automated production lines, vacuum gripping systems and pneumatic fixture applications, delivering reliable pressure and vacuum monitoring for industrial automation equipmentSMC Corpor.... The product family includes three core variants: ZSE30A for vacuum (0.0 ~‑101.0 kPa), ZSE30AF for compound pressure (‑100.0 ~100.0 kPa), ISE30A for positive pressure (‑0.100 ~1.000 MPa). Output options cover NPN / PNP open‑collector switching outputs, plus analog voltage output (1‑5 V) or analog current output (4‑20 mA) for PLC signal acquisitionSMC Corpor....

Hardware Overview & Basic 3‑Step Setup

The unit features a 4‑digit dual‑color LED display. OUT 1 indicator is green, OUT 2 indicator is red. Three front‑panel keys are available: △(UP), S(SET/Enter), ▽(DOWN). Simple three‑step setting workflow:

1. Push the S key to enter parameter setting mode.
2. Adjust target set‑value by △ and ▽ buttons.
3. Press S key again to confirm and finish configuration.

Multiple mounting options are supported. Bracket A1/A2/A3 enables multi‑orientation installation. Panel‑mount adapter allows flush cabinet mounting; multiple units can be mounted side‑by‑side without clearance gap. Process connection includes R1/8 thread or quick‑change one‑touch fittings (straight / elbow for φ4 / φ6 tubing). The clip‑on fitting can be replaced on‑site. The 2‑meter connector‑type lead wire is equipped with connector cover for enhanced field protectionSMC Corpor....

Key Built‑in Functions

1. Setting Copy Function (F97) All configured parameters from one master unit can be copied to up to 10 slave sensors at one time, maximum communication distance 4 meters. This function drastically cuts commissioning time for multi‑station machines and eliminates human typing errors. All devices default to slave mode from factory; one unit must be switched to master mode via keypad before copy execution. Dedicated communication cable ZS‑38‑5L or ZS‑38‑U is required for inter‑unit connection.
2. Auto‑Preset Function (F5) The switch automatically calculates optimized trigger thresholds based on real‑world pressure cycles. Especially useful for vacuum suction applications: after repeated suction‑release cycles against work‑pieces, the device determines ON/OFF set‑points automatically without manual estimation.
3. Anti‑Chattering Function (F3) Selectable response filter time: 20 ms, 100 ms, 500 ms, 1000 ms, 2000 ms. Pressure readings are averaged within the set time window to filter transient pressure spikes caused by cylinder or ejector operation, preventing unwanted switching mis‑triggering and unstable PLC signals.
4. Zero‑Reset, Peak & Bottom Hold Function Zero‑out function compensates minor zero‑point drift within specified range. Peak / bottom function records maximum and minimum pressure values during operation. Hold value can be cleared by pressing combined buttons longer than one second, helpful for troubleshooting pressure fluctuation issues.
5. Unit Switch, Power‑Saving & Key‑Lock Pressure units including kPa, MPa, bar, psi can be switched on‑site. Power‑saving mode activates after 30‑second idle status to reduce power consumption up to 20%. Key‑lock prevents unauthorized parameter modification; secret‑code protection can be enabled. Display calibration permits fine readout adjustment within ±5% of reading to compensate sensor deviation.

Wiring & Safety Instructions

Power supply: DC 12‑24 V. Brown = DC(+), Blue = DC(‑), Black = OUT1, White = OUT2. The FUNC terminal must be interconnected with special cable when using copy function.

⚠️ Important Safety Notes

1. Working fluid: compressed air only. Do NOT use for corrosive or flammable gas.
2. Do NOT apply pressure beyond rated range. Settings can be entered out‑of‑range but accuracy specifications are not guaranteed.
3. Perform all wiring under power‑off condition. Hot‑swap of connector is forbidden.
4. Torque for thread connection: 7‑9 N·m to avoid thread damage.
5. Operating temperature: 0 ~50 °C. Not for explosive‑hazard atmosphere.
6. Error code Er1 / Er2 indicates output over‑load current (>80 mA). Check external load circuit. For system error Er8 please contact SMC technical support for diagnosisSMC Corpor....
