Troubleshooting:
A faulty output component will not be identified by the Input/ Output screen. If
all inputs, qualifiers and outputs are correct for the machine operation selected,
yet the operation does not function as it should, the output component may be
faulty. In this example, the controller output is occurring but the faulty component
is preventing the operation from functioning. Test the specific output and output
wiring (see Testing (page
PTO operation example:
•
Test the PTO switch (input) and the seat switch (qualifier). If ON and OFF
do not alternate when the switch is moved OPEN and CLOSED, the switch
or the circuit wiring for the switch is faulty and should be tested (see
(page 5–36)).
•
The qualifiers Left Deck Float, CTR Deck Lower/ Float, Right Deck Float and
High Range are solenoids that must be energized before the operation can
proceed. The solenoids are energized by controller outputs, and therefore
cannot be tested using the InfoCenter procedure. Test the specific output and
output wiring (see Testing (page
5–36)).
