Diagnostics
IO
IO is used to review machine information collected
by the control panel. The following data types are
currently available:
• A/D - Review analog voltages for troubleshooting.
• Modules - Review the status of selected relays. A
relay is considered a module.
• GPS - Review a machine's current location and
heading.
From the main screen, press
SYSTEMDIAGNOSTICS
and
4
to
display the IO screen. See Figure 33-1.
A/D - Analog to Digital Voltages
A/D is used to review analog voltages. There are
twelve analog channels (0 through 11) available for
monitoring voltage feedback. Below is a description
of each channel.
• Channel 0 monitors voltage from the pressure
transducer. An acceptable range is between 1000
and 15 mV.
• Channel 1 monitors voltage from the angle sen-
sor. For more information, see the Angle Setup
section beginning on page 25.
• Channels 2 through 7 are not used. Ignore any
random values that might appear.
• Channel 8 monitors voltage from the 5 VDC power
supply. An acceptable range is between 4750 and
5000 mV.
• Channels 9 through 11 are not used. Ignore any
random values that might appear.
Reviewing A/D
To review analog voltages, start from the Status
screen and press
SYSTEMDIAGNOSTICS
,
4
, and
1
to display
the A/D screen. See Figure 33-2.
