Wire Guidance

Wire Guidance

Wire guidance is a means to automatically steer the truck while traveling in an aisle. It offers precise steering at full-speed travel in very narrow aisle (VNA)applications.

A wire guidance system consists of two sub - systems.

Warehouse - installed equipment includes a guide wire and line driver. The guide wire is in the floor and emits an alternating current (AC) signal at a specific frequency and amplitude generated from the line driver.

Truck - installed equipment includes:

- Two guidance sensors, tractor end and load end

- Guidance manager, in tractor

- Filter card, on guidance manager

- Travel speed feedback encoder, on top of the drive motor

- Steer feedback encoder, on top of the steer motor

- Auto manual switch, on operator console

- Associated cables and mounting brackets

The truck must learn the amplitude and frequency of the guidance signal to properly track the guide wire.

NOTE: This manual will cover all truck - installed equipment.

To operate wire guidance, see the Model 7BPUEl5 Operator Manual.

See "Wire Guidance " on page 8- 1.

Cold Storage

Cold storage is a factory-installed option that enables truck operation in temperatures of -20" F (-28.86" C) to 40" F (4" C).

On cold storage trucks, the electrical panel on the tractor is completely enclosed to contain heat. Components added to the truck for cold storage are listed in the tables below and shown
