Section 3. Systems Overview Modes of Operation
When the Auto/Manual switch transitions from Manual to Auto, the stored values are cleared. When the Auto/Manual switch transitions from Auto to Manual after tracking the wire, the following values are displayed (see Figure 3-9):
wire, minimum and maximum tracking values are automatically recorded. The following table lists acceptable values. DFW”

NOTE: Coil NW% can range from 0 to 199%. When traveling TF, the NW% coil readings are from the tractor end antenna coils. When traveling FF, the NW% coil readings are from the load end antenna coils. The display alternates automatically, depending on direction of travel. Use the up/down buttons to obtain differences between the TF and FF tracking information when the truck is not over the guide wire and tracking. Procedure: Enter Wire Guidance/Maintenance Mode/Tracking Values. Lock the truck onto the wire (if presently locked onto the wire, cycle the Auto/Man switch to clear existing values) and travel in both directions. Drive the truck the full length of the aisle. As the truck travels on the

Use Coil Values to monitor what the Guidance Manager is sensing from the individual antenna coils for multiple frequencies. The readings can be used to aid in troubleshooting the system. The Now, Min, and Max coil strengths can be selected for display. When the truck is centered over the wire, the inner (near wire) coil signal strength is typically about 100%. Outer (left and right) coil signal strength is approx. 60% to 70%. These values are affected by truck position relative to the wire and wire depth in the floor. For more information, refer to “Wire Guidance Troubleshooting” on page 5-23. Clear WG EEPROM This is used to clear the EEPROM on the Guidance Manager card. When this occurs, learn Wire Guidance must be performed. See “Learn Wire Guidance” on page 3-23. 1. Select Clear WG EEPROM from Wire Guidance sub-menu. 2. Reset? N is displayed. Press the right button. 3. Reset? Y is displayed. Press Enter. The wire guidance EEPROM is cleared.
Evt Log When Event Log is selected, the last twenty error codes recorded are displayed. Each entry shows the code and the date and time of occurrence.
