COURSE OF ACTION
The travel function will not operate
regardless of the travel switch posi-
tion.
The travel will not function with the
travel switch in the “Hand” travel
position. The unit operates properly
with the travel switch in the “Auto”
position.
1. Check the travel switch for proper
operation. Also check associat-
ed leads for loose or faulty con-
nections.
2. Check the travel receptacle and
associated leads for loose or
faulty connections.
3. Make sure the travel unit is oper-
ational.
1. Check the travel switch and asso-
ciated leads for loose or faulty
connectioins.
1. With the travel switch (S2) in the
hand travel position, and the
115VAC input power applied to
the NA-5 unit, check for 115VAC
at the travel receptacle. 115VAC
should be present at leads #531
to #532. 115VAC should also be
present at leads #25 to #531. If
either of these two voltages are
missing or not correct check the
lead harness, switch (S2) and
travel receptacle for loose or
faulty connections. See wiring
diagram.
2. If the above voltages are correct
the problem is in the travel unit or
connecting cable.
1. The travel switch may be faulty.
Check or replace.
