Operating Instructions
The ANDONT 2-Stack LED Andon Tower Signal Light is controlled via two independent ABB selector switches located on the control box. Each switch corresponds to a specific light stack (Red or Green).
- To turn on a light: Rotate the corresponding selector switch from the 'OFF' position to the 'ON' position. The light will illuminate steadily.
- To turn off a light: Rotate the corresponding selector switch from the 'ON' position back to the 'OFF' position.
You can operate the Red and Green lights independently to signal different statuses on your production line or workstation.
