| Height | 0.6 m to 1.7 m from the ground, based on operator height |
Tip: Walk around your workspace and imagine where someone would stand during an emergency. That’s where you want to install the switch.
Preparing Mounting Holes
Once you pick the location, you need to get the panel or surface ready for the emergency stop switch. Here’s how you do it:
- Mark the exact spot for the switch using a marker or pencil.
- Check the mounting hole size for your emergency stop push button. Most use a 22mm hole, but always double-check.
- Use a drill with a hole saw or step bit to make the hole. Drill slowly to avoid cracking the panel.
- Clean away any dust or sharp edges around the hole.
Make sure the hole lines up with the operator’s reach. If you drill in the wrong spot, the switch might not be easy to use.
Mounting the Emergency Stop Switch
Now you’re ready to install the switch. You want it to stay put, even if someone hits it hard during an emergency. Follow these steps:
- Insert the emergency stop switch into the mounting hole.
- Use the mounting hardware that comes with the switch. Tighten the nut or screws by hand first, then use a wrench or spanner for a snug fit.
- Don’t overtighten. You want the switch secure, but not cracked.
- Check that the switch does not wiggle or move. It should feel solid.
Here’s a quick checklist for a secure installation:
- Choose the right location for the emergency stop switch.
- Use strong fasteners to keep the switch from loosening due to vibration.
- Test the switch after mounting to make sure it works.
- Add clear signage near the switch.
- Train everyone on where the switch is and how to use it.
If you work in a place with lots of vibration, check the switch every month to make sure it stays tight.
How to Wire the Emergency Stop Button
Wiring the emergency stop push button is the most important part. If you wire it wrong, the switch won’t work when you need it. Here’s how to wire the switch step by step:
- First, turn off all power to the panel before you start.
- Understand the difference between normally open (NO) and normally closed (NC) contacts. Normally closed contacts break the circuit when you press the switch, which stops the machine.
- Most emergency stop switches use NC contacts for safety. If the wire gets cut or the power fails, the switch will stop the machine by default.
- Connect the wires to the correct terminals. Use a screwdriver to tighten the screws, but don’t overtighten.
- If you need to wire imo emergency stop button, follow the same steps. Always check the wiring diagram that comes with your switch.
- Double-check your connections. Loose wires can cause the switch to fail.
- A typical wiring setup for a start-stop circuit looks like this:
- Power supply connects to the NC contact of the emergency stop switch.
- The other side of the switch goes to the relay coil.
- The NO push button connects in parallel for starting.
- Ground all metal parts for safety.
The stop push button should be programmed in the PLC as a normally open contact, but the physical relay wiring should use a normally closed contact. This way, if the wire breaks or power is lost, the switch will stop the machine.
If you’re not sure how to wire the emergency stop button, ask a professional. Safety comes first.
Testing the Emergency Stop Push Button
After you install the switch and finish wiring, you need to test it. Testing makes sure the emergency stop switch will work when you need it most. Here’s a simple plan:
