215575 160 Revision B
Alarm conditions:
If an error message is received from the fuse panel, an audible alarm sounds. The LCD on the electronic instrument panel
(EIP) indicates a header system error as HDR CTRL followed by HGT ERR for height, and HDR CTRL followed by TILT ERR for
tilt. The header height LED flashes yellow two times every second.
When this alarm occurs, a buzzer will also sound 5 times every 10 seconds.
When an alarm condition occurs, a green LED begins flashing (green, yellow, or red depending on the input). In addition, a
message is displayed on the LCD which explains the nature of the alarm. For example, HYD TEMP, OPEN, SHRT will be
flashed alternately.
Diagnostic fault failures: For an illustration, refer to Figure 4.113, page 159.
Pressing header height switch (B) for a minimum of 5 seconds will put the EIP in header diagnostic mode. LCD (A) will
display the message HDR DIAG when the EIP has entered header diagnostic mode.
In this mode, after 3 seconds, the header fault parameter labels are displayed on the EIP’s LCD. All the information
displayed on the LCD is read-only.
OK (C) and CLEAR (D) buttons allow you to scroll through a list of parameters. If there are no active fault codes, the EIP’s
LCD will display NO CODE.
When a parameter is displayed, its label is displayed for 3 seconds, after which its value is automatically displayed.
Pressing OK button (C) while the value is displayed will cause the EIP to advance to the next parameter and display its label.
When a parameter label is displayed and OK button (C) is pressed before 3 seconds, the parameter’s value will be
displayed.
Pressing AREA (E) will cycle through options. When LEFT is displayed on the LCD, press OK button (C), and the auto header
height control (AHHC) voltage will show on the display.
Press DIST button (F) to cycle back through the table.
Press CLEAR button (D) to exit the header diagnostics menu.
