The use of the up/down arrows (”
” and “
”) will allow the user to scroll in the menu.
When pressing simultaneously on an “arrow” key and the “?” key, the display will
move from one page to the other. Pressing “
” will show calibration details and also
the original software version of the underlined sensor, this is not available for all sensors
Notes:
Pressing #5 “ESC” takes you to the previous menu or exits from the
diagnostic mode.

In the diagnostic menu, this is the typical displayed information:

Some applications have more than one angle or length sensor. In this case, all of the
angle sensors are listed first then length sensors will follow. The first angle sensor to be
listed is the one installed closest to the main boom base.
Referring to the example above, for the “angle 1” sensor, values “ain1” and “ain2” vary
depending on the inclinometers in the X and in Y axes that are used to calculate the
angle. These values are normally between 1200 and 2900 bits. DR+ represents the
D.C voltage level of excitation on the angle/length card and must be close to 5.00V.
When the multiple reel option is required every angle/length card has an ATB option
that can be activated by dipswitch #4. For the angle/length card, which is not monitoring
the ATB, N/A is shown under a2b instead of 0 or 1, indicating it is not available on this
card. 0 is a safe condition and 1 will show a two-block condition.
For the “length 1” sensor, the value “ain1” represents the boom extension value in bits.
It may vary between around 50 and 975 bits. The “length 1” sensor “ain2” value is
reserved for future expansion.
Note: “angle 1” sensor and “length 1” are physically located on the same card.
