• Control handle Center Switch (CS) command with 0
neutral and 1 active.
• PUMP command in percent from neutral with + right and
- left.
• Park BRAKE command with 0 engaged and 1 released.
• Swing Brake Pressure (cranes without swing lock).
• Swing LOCK command with 0 engaged and 1 released
(cranes with swing lock).
• Measured pump RT PRES (psi) when swinging right.
• Measured pump LT PRES (psi) when swinging left.
• DOS (digital output status) displays a binary number (or
total) if the digital output signal is disabled to: pump 1 (1),
pump 2 (2), swing brake (4), swing lock in (8) or swing
lock out (16).
Trk (Travel)
The right and left TRK (Travel) screen displays the following
information:
• Control HANDLE command in percent from neutral with
+ forward and - reverse.
• The normal operating voltage (V) outputs of the control
handle range 2.6 to 4.5 volts for forward and 0.5 to 2.4
volts for reverse.
• Control handle Center Switch (CS) command with 0
neutral and 1 active.
• Left or right PUMP command in percent from neutral
with + forward and - reverse.
• Measured track PRESS (psi) at right or left crawler track.
• Park BRAKE command with 0 engaged and 1 released.
• MOTOR command with 0 high speed/minimum
displacement and 1 low speed/maximum displacement.
• CRUISE indicates status of travel cruise with 1 engaged
and 0 disengaged.
• DOS (digital output status) displays a binary number (or
total) if the digital output signal is disabled to: right pump
(1), left pump (2), travel brake (4), or motor (8).
FCN (Front Console Node)
The status of the digital inputs and outputs of the front
console controller is displayed in the FCN screen. Each bank
can indicate the state of up to 255 individual digital inputs or
outputs. The FCN screen displays the following information:
• Front console digital input DI BANKS 1, 2, 3, and 4.
• Front console digital output DO BANKS 5 and 6.
• Only programmers use TF BANKS 1, 2, 3, and 4.
Each individual input/output is assigned a number (identifier)
in the binary system (powers of two). The identifiers of all
inputs/outputs that are ON (active) for each bank are added
for a total of 0 – 255. The number displayed for each bank is
the
sum of all identifiers that are ON in that bank. Each
possible ON/OFF combination per bank has a unique total.
To determine the state of an individual digital input or output
(crane component), find the individual crane component in
Table 3-11 or Table 3-12 , for example: Seat Switch FCN-3-1 .
• The first part of the Code Number FCN indicates that the
individual input or output is located in the FCN computer.
NOTE: If the Code Number starts with CAN, see CAN
screen for input/output
.
• The second part of the Code Number 3 is the bank
where the individual information is shown on the FCN
screen.
• The third part of the Code Number 1 is the item
identifier .
To determine the state of the individual input/output in a
bank, find the number displayed for the bank in the
numbered column of
Table 3-13 . In the corresponding row
the identifier numbers that are ON (active) in the bank are
shaded. In the above example if 1 is shaded the Seat Switch
is ON (active).
