Thermostat Calibration
Turn on machine and allow adhesive to reach operating temperature
(about 1/2 hour warm up time). Using a surface probe pyrometer,
measure the temperature just above one of the glue jets (refer to Figure 71 for correct probe location). If the temperature measured with the
pyrometer is the same as shown by the thermostat control knob, the
thermostat is calibrated. If the temperatures are not the same, recalibration can be accomplished by the following method.
Calibration Procedure
1. Set the thermostat control knobs to the same temperature measured with the
pyrometer.
2. Remove the thermostat control knobs (with the knobs removed the calibration
adjusting screw will be visible by looking into the knob mounting stud).
3. Using a small screwdriver, turn the calibration adjusting screw until the heater
indicating light goes off.
4. Turn the screw in the opposite direction until light comes on.
5. Then, turn the screw only until the light goes off.
6. Replace the knobs, set both thermostats at operating temperature and recheck in
an hour.
Note: When calibrating the adhesive applicator pump thermostat, all thermostats
should be calibrated.
