Extended Product Information

FAQs

What is the purpose of the M22-PVLT pushbutton?

The M22-PVLT is an emergency stop pushbutton designed to immediately halt machinery or processes in hazardous situations. It features a mushroom-shaped actuator for quick activation and a turn-to-release mechanism for resetting.

Does the M22-PVLT include the necessary wiring or safety relay?

No, the M22-PVLT is the pushbutton actuator unit itself. It needs to be wired into an existing safety control system, such as a safety relay or a programmable logic controller (PLC), to function as an emergency stop.

What does the IP67/IP69K rating mean?

This rating indicates a high level of protection. IP67 means the device is dust-tight and protected against immersion in water up to 1 meter for 30 minutes. IP69K means it is protected against high-pressure, high-temperature water jets, making it suitable for wash-down environments.

How is the LED illumination powered?

The LED illumination requires a separate electrical connection and a power source. You need to supply the correct voltage to the illumination terminals as specified by Eaton for this component.

What is the difference between 'turn-to-release' and other release methods?

Turn-to-release is a common method where twisting the button unlocks it. Other methods include push-to-release (pressing the button again) or key-release (requiring a specific key to unlock).

Can I use this button for normal On/Off switching?

No, the M22-PVLT is specifically designed and certified for emergency stop (Emergency Switching Off - ESO) functions. It should not be used for general operational control.

What is the diameter of the mounting hole required?

This pushbutton is designed for a standard 22 mm diameter mounting hole, common in industrial control panels.

Troubleshooting

Button does not latch when pressed.

Ensure the internal latching mechanism is clean and not obstructed. Verify that the button is correctly seated in its mounting.

LED illumination is not working.

Check the electrical connections to the LED element. Verify that the correct voltage is being supplied to the illumination circuit and that the voltage is within the specified range for the LED.

Button does not release when turned.

Gently try turning the button with slightly more force. If it remains stuck, carefully inspect for any physical obstructions or damage to the release mechanism. Ensure the button is fully engaged before attempting to release.

Device is not triggering an emergency stop signal.

Verify that the button is correctly wired into the emergency stop circuit. Check the continuity of the switch contacts when the button is pressed and released using a multimeter. Ensure the connected safety relay or control system is functioning correctly.

Pros and Cons

Pros

  • Highly visible 38 mm red mushroom actuator.
  • LED illumination for clear status indication.
  • Simple and fast turn-to-release reset mechanism.
  • Robust IP67/IP69K rating for harsh environments.
  • Designed for critical safety applications.

Cons

  • Requires integration into a larger control or safety circuit.
  • Illumination requires a separate power supply.
  • Primarily a signaling and manual reset device; does not include internal switching logic on its own.
  • Limited to emergency stop functionality; not a general-purpose switch.

Setup, Compatibility & Care

Setup:

The Eaton M22-PVLT is designed to be mounted into a standard 22 mm diameter knockout on control panels or enclosures.

  1. Ensure the control panel is de-energized.
  2. Insert the M22-PVLT unit through the 22 mm hole.
  3. Secure the unit from the back of the panel using the provided mounting hardware or a compatible locking ring.
  4. Connect the necessary electrical wiring for the LED illumination and the emergency stop signaling circuit according to the wiring diagram and local electrical codes.

Compatibility:

  • This pushbutton requires integration into a safety control circuit. It functions as an input device and needs to be wired to a safety relay, PLC, or control system that can interpret the stop signal and initiate appropriate machine shutdown.
  • The LED illumination requires a separate power source, compatible with the voltage rating of the LED element (check product documentation for specific voltage requirements).
  • Fits standard 22 mm mounting holes common in industrial control panels.

Care:

  • Cleaning: Wipe the exterior with a clean, damp cloth. Avoid using harsh solvents or abrasive cleaners that could damage the plastic or lettering.
  • Inspection: Regularly inspect the button for any signs of damage, wear, or obstruction. Ensure the mushroom head moves freely and the turn-to-release mechanism functions correctly.
  • Electrical Connections: Periodically check electrical connections for tightness and corrosion to ensure reliable operation. Always de-energize the system before performing any maintenance.
