2.3 Lane Home Switch Error
Local Screen – Page 57 Master Screen – Page 57
The lane home switch error is displayed if the target carrier has entered its ramp down
deceleration when commanded to come home, and has stalled on the dead stop at the
drive unit.
Corrective action
1. Visually inspect the home switch for signs of damage. Move the target carrier
beneath the home switch and check if the light on the home switch illuminates.
2. If the home switch is illuminated when the target carrier is below the home switch,
gently rock the target carrier from side to side. The home switch LED should stay
illuminated. If it does not, move the home switch down closer to the target carrier.
3. If the home switch does not illuminate, place a metallic object (knife) near the home
switch. If the LED does not go on, check the wiring back to the Drive Unit PCB for damage.
The carrier can be manually pushed forward or pulled back by hand.
The home sensor will activate through the entire width (about 18”) of the carrier.
The top of the carrier is metal and the sensor triggers when it detects metal.
