ANALYZER
EXPLANATION
Analyzer function supports operations for inspecting/investigating faulty section by displaying the condition of the
control system, using communication between each controller and the multifunction display or plug-in analyzer.
By switching the multifunction display to analyzer mode, or connect the plug-in analyzer to the diagnosis connector,
operative conditions of the sensor actuator that is used for traveling functions, or the error information detected by
the controller can be read. This is very useful for checking operative condition of each function and saving time for
repairing when there is a defect.
The analyzer functions can be used to make servicing faster and easier.
Refer to 8FG series repair manual for how to use the analyzer functions.
The analyzer functions include the following functions.
1. Diagnosis memory function (DIAG MEMORY)
The controller stores a maximum of the past 10 error codes (diagnosis codes) for faults that have occurred in the
electrical system. The diagnosis function is the function that reads these error codes and displays them on the
display.
The error code and its time of occurrence as a key ON hour meter time are displayed on the display.
2. In/out monitor function (I/O MONITOR)
This function displays the analog input value of each sensor relating to driving, material handling, FHRS, SAS,
and OPS on the display. By monitoring this display it is possible to judge whether each circuit and sensor has a
fault or not.
I/O ENGINE CTRL: The display shows various kinds of input value such as the analog input voltage from each
sensor to the controller, as well as control correction values and the status of the output to
the relay.
