SRVO-002: Teach pendant E-stop

The red emergency stop button on the teach pendant is pressed or latched.

What it means

The red emergency stop button on the teach pendant is pressed or latched. Simple as alarms get - until it won't reset, at which point the pendant itself is the suspect.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Pendant E-stop button latched in.
  2. Faulty teach pendant (button or internal circuit) if the alarm persists with the button released.

How to fix it

  1. Twist the pendant E-stop button clockwise to release it, then press RESET.
  2. If the alarm won't clear with the button released, the pendant is the likely fault - swap in a known-good pendant to confirm before buying one.
