Route Management Manual

The Truck

Ramp Zone

Program a Ramp Zone when the truck is trained to use ramps in the facility. Each truck is labeled with it’s maximum grade capability.

NOTE: If training a route with a drop behavior before a ramp, check to make sure the forks will not contact the ramp in the fully lowered position. The truck travels with the forks raised prior to a drop behavior; however, the forks do not return to the raised position after a drop behavior.

NOTE: “Set Cart Train Length” must be used when training a ramp zone with a tow tractor and carts. This determines the exit point for the ramp zone once the cart train has completely cleared the ramp. Always train with the maximum number of carts (maximum length).

When a Ramp Zone is programmed, the automated truck’s light curtain profile is adjusted for the inclined floor (when traveling up a ramp) or declined floor (when traveling down a ramp). This allows the truck to begin traveling up or down a ramp without the sensors falsely detecting the change in grade as an obstruction. It is very impo rtant to follow the instructions for programming ramp behaviors. For detailed instructions for programming ramp behaviors, see “Adding Ramps” on page80.

Programming a Ramp feature requires the following input:

•Ramp direction (up or down)

•Ramp grade

•Ramp exit position

Uneven Floor Zone

When an Uneven Floor Zone is programmed, the automated truck’s light curtain profile is adjusted to travel over pitted or non-level floor surfaces. When the automated truck enters an Un even Floor Zone, the light curtain is automatically adjusted up or down the amount programmed during training. This allows the truck to travel without the sensors falsely detecting the change in floor surface as an obstruction, see “Adding an Uneven Floor Zone” on page84.

Fire Door Zone

NOTE: This behavior requires a fire detection device to be integrated with the truck. Although you are able to program a Fire Door Zone; this behavior will not function as intended unless a fire detection device is integrated. Ask the facility manager if the truck has been integrated with a fire detection device adapted to your individual facility.

The Fire Door Zone behavior is inte nded to minimize the possibility of blocking the complete closing of a fire do or. Note that this feature is disabled in manual mode. A Fire Door Zone should be trained under each fire door the truck passes through. Under normal oper ating conditions, the Fire Door Zone will not affect the truck’s behavior. If the fire detection device on the truck is triggered, the truck comes to a stop unless it is in a Fire Door Zone. If the truck is at any point inside the Fire Door Zone, it continues traveling until it reaches the end of the zone, then stop s. No pause or Drop-Off behaviors can be programed in a Fire Door Zone.

NOTE: The Fire Door Zone does NOT ove rride the obstruction sensor’s or light curtain’s stop fields. The truck will still stop if an obstruction is detected in either of these fields, regardless of Fire Door Zones.

A Fire Door Zone is trained by defining a start and end point along the route. The Fire Door Zone should be st arted 44 inches (1118 mm) before encountering the fire door. The end of the zone should be programmed at the point where the truck and any potentia l payload (trailers included) have passed through, and are completely clear of, the fire door.
