In today’s healthcare and logistics environments, HAION Caster's Power-Assisted System (PAS)
has become an essential tool for reducing physical strain and improving transport efficiency.
However, when it comes to "electrification," safety is always the non-negotiable baseline.
This article explores the most critical safety mechanism: the Emergency Stop Button.
I.What is the Emergency Stop Button?
The HAION PAS is equipped with a bright, high-visibility emergency stop button.
Its primary function is to allow operators to cut off the drive power via the shortest path
and at the highest speed during system anomalies or sudden dangers.
Specifications and Features:
  ◆Power Cut-off Mechanism:
     Immediately interrupts power supply to the motor upon activation.
  ◆Locking Function:
     Automatically locks after being pressed to prevent accidental restoration of operation
     due to vibration or misoperation.
  ◆Installation Position:
     The button is typically installed at the operator's abdominal or chest height.
     This is a crucial ergonomic safety consideration: if a cart rebounds or an operator leans
     forward due to instability, their body will naturally collide with the button,
     cutting power instantly through physical contact. 
II. Why is the Emergency Stop Vital for Medical and Industrial Environments?
Whether pushing heavy medical instruments through hospital corridors or moving
high-load racks in a factory, minor control errors can lead to serious consequences.
  ◆Intuitive Protection:
     If a cart rebounds, the abdominal-height button ensures the power stops immediately
     upon contact with the body, preventing "crush" injuries.
  ◆Collision Prevention:
     If a cart is about to hit a pedestrian, doorway, or expensive equipment,
     pressing the button immediately disables the electric assist.
  ◆Labor Safety Compliance:
     According to international standards, mobile electric equipment must
     have a rapid stop function. This is not just about protecting staff—
     it is a requirement for occupational safety inspections.
III. 3 Steps to use the HAION PAS Emergency Button
To ensure equipment longevity and personnel safety, operators should be familiar
with the following standard procedures:

Step	Description
1.Trigger	In an emergency, press the button directly to cut power to the motorized system.
2.Check	Before resetting, ensure the cart is stable and all obstacles have been removed
3.Reset	Rotate the button as indicated by the arrows (to the left/counter-clockwise). Once it pops up, the system can be restarted

IV. Frequently Asked Questions (FAQ)
     Q1: Why is the button installed at abdominal/chest height?
        A: This is an ergonomic safety design. In sudden accidents (like a cart rebounding or
        pinning the operator), hands may be panicked or busy gripping the handles.
        By placing the button at this height, the operator can use their natural reflex of
        leaning forward to trigger the stop, minimizing potential injury.
     Q2: Does the cart "lock up" instantly when the button is pressed?
        A: No. The HAION PAS utilizes a "Coasting Stop" design. When the button is pressed,
        a hard-wired cut-off occurs, stopping motor power instantly. The wheels will then transition
        to a manual state and glide to a natural stop based on inertia.
       This design ensures:
           ◆The operator maintains control over direction and positioning.
           ◆It prevents tipping or inertia-related impact caused by sudden mechanical locking.
           ◆A safer, more controlled stopping experience.
     Q3: The button won't pop back up and the cart won't move. What should I do?
        A: This is the safety locking mechanism. To restore operation,
        check that the environment is safe, then rotate the button head clockwise
        (as indicated by the arrows).The button will pop up, and you can restart the system.
     Q4: How do I check if the Emergency Stop Button is working properly?
        A: 1. Trigger Test:
            While the electric assist is active,
            press the button and confirm the motor stops immediately.
            2. Reset Test:
            After rotating to unlock,
            ensure the button pops back up smoothly without unusual noise or sticking.
