Section 8
Troubleshooting
This section describes troubleshooting for the Mast System. Use care to understand and follow
all precautions while troubleshooting the Mast System.
This section provides troubleshooting information as follows:
•
Error Conditions (Section 8.1)
•
Error (Fault) Codes (Section 8.2)
•
Warning Codes (Section 8.2.2)
8.1 Error Conditions
Table 8-1 shows many of the more probable error conditions. Where multiple probable causes
can explain an error condition, they are listed in order of probability from highest to lowest. It
should be noted that some “errors” are more aptly called “states” and do not necessarily indicate
improper operation.
Table 8-1 Troubleshooting Error Conditions
Problem Possible Cause Possible Solution
Precondition Contact
Closure Condition
Provisions have been made
for a precondition contact
“handshake” circuit. If the
circuit is open, the operation
of the mast is prevented and
the software revision level is
shown on the Display. This
feature is normally disabled
by a jumper installed across
the contacts (J1 Pins A,B).
The primary application of
this capability is a sensor on
a hatch above the mast.
Correcting the condition will
clear this error.
Precondition is not present
(i.e. the hatch is closed).
Establish the proper
precondition (i.e. open
the hatch).
Damaged/inoperative
pre-condition switch.
Check the switch for
continuity and replace if
necessary.
Missing connector wire
(no handshaking used).
(There is not hatch.)
Refer to the wiring
schematic (Figure 2-9) for
the Universal Control Box,
and replace the jumper
between the two
appropriate contacts.
Malfunctioning mast control.
Contact an authorized
service center for
evaluation and possible
return for repair.
