Unit Error Code Categories
An Error Code is a three-digit number. The keypad on the unit in error first shows the one-digit 
segment. The first one-digit segment represents the error category.
1. Press the 
FUNCTION (-) button on the keypad to show the second two-digit segment. The second 
two-digit segment refers to a specific numbered component.
Example: If the Error Code is 1-47 on a Connection Unit, it represents Sensor number 47 (SN47). 
This Error Code means that the sensor associated with the right safety cover over the Loading 
Arm detected a problem.
2. Press the 
FUNCTION (+) and FUNCTION (-) button alternately to toggle back and forth to see both 
sets of digit segments.
