Wire Guidance
Wire Guidance Wire guidance is a means to automatically steer the lift truck while traveling in an aisle. It offers precise steering at full-speed travel in very narrow aisle (VNA) applications.
If the warehouse portion of the guidance system has a different line driver output, refer to “Learn Guide Wire Frequency” on page 3-9.
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.
•
Lift truck-installed equipment includes: • Two guidance sensors, tractor-end and load-end • Guidance Manager (GM) • Steer feedback encoder • Auto/Manual switch, on operator console • Associated cables and mounting brackets
The lift truck must learn the amplitude and frequency of the guidance signal to correctly track the guide wire. NOTE: This manual covers all lift truck-installed equipment. For information on warehouse-installed equipment, refer to PDSS-0051, Raymond Wire Guidance. To operate wire guidance, refer to the Operator Manual.
Wire Guidance Setup This procedure should not normally have to be performed. For the lift truck to guide correctly, the following must be true: •
For 5.2 kHz, the current through the guide wire must be 100 mA peak-to-peak ±10%.
•
For 6.25 kHz, the current through the guide wire must be 225 mA peak-to-peak ±10%.
