24 Outputs
The Tunnel Master® Jr. relay box is the control center for firing the various outputs or services in the wash
tunnel like the soap foamer, reclaim motor, and more. The Tunnel Master® Jr. Controller relay box provides
automatic, computer controlled, or manual firing of the outputs. The relay box can control up to 24
outputs. Each toggle switch controls the operation of one output or service.
The switches have three positions:
UP = Manual Override. Manually turn on output. (This feature can be turned off if desired.)
MIDDLE = Output Off. The output is off and will not fire.
DOWN = Computer controlled on position (normal).
