Inspect all terminal block
connections
for
loose
or
disconnected
wires by making
certain the screws
in
each
terminal block
are
securing the
wires.
If
any connections
are
loose
or
have
pulled
out of
the
terminal blocks,
reconnect
and
retighten
the connections
(see
Figures
S and
T). After
reconnections have
been made,
reassemble the applicator making
sure
wiring is properly
located
and
will
not
be
pinched
when handles
are
closed (see Figures
P,
Q
and
R). Reinstall
the
previously
removed temperature module
(see Figure
O).
If
all terminal block
connections were
initially
found to be tight,
proceed to
the
next
step.
Important:
Power switch MUST
be
in "1" position
(red visor visable) for
step

Check
electrical continuity of heater/TCO/switch
assembly.
Using
an
ohmmeter, measure
across
the terminals numbered
3
and
4 on
the
top
terminal block labelled TB2. These
are
the terminal block positions
for
the brown
and
blue wires from
the
power switch (see Figure
S).
Value measured should
be between 130-145 ohms.
If
measured
value
is not in this
range, replace the heater/TCO/switch assembly by
ordering

If
measured value
is within the specified range, proceed to the next
Step.

Disconnect the
electrical power
and
make
sure
the applicator
has
cooled
to room
temperature before
servicing. Failure to
disconnect
electrical power or failure to allow
the
applicator to cool
before
servicing may
cause
electrical
shock or burns.
