Troubleshooting (continued)
Condition 1:
Applicator
will not heat
! WARNING
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.
12. 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 “on” position (red visor visible) for step 13.
13. Check electrical continuity of heater/TCO/switch assembly. Using an
ohmmeter, measure across the terminals numbered 3 and 4 on the top
terminal block labeled TB2. These are the terminal block positions
for the black wire from the power switch and the white wire from the
heater, respectively (see Figure S).
Value measured should be between 40-50 ohms. If measured value is
not in this range, replace the heater/TCO/switch assembly by ordering
3M? Heater Kit #62-9680-9731-1.
If measured value is within the specified range, proceed to the next
step.
