Overheat Protection Sensor
The Finesse is equipped with a temperature sensor that interrupts
one leg of the AC line in the event of a rear panel overheat. The
sensor opens at a nominal temperature of 160
o
F and is not
adjustable. The sensor is mounted on the rear panel near the output
transistors.
In the event of an overheat condition, all functions will cease and the
green lamp inside the main power switch will turn off. The unit will
automatically reset after about 30 to 45 seconds.
Under normal clinical conditions, the unit should perform without
any activation of the thermal shutdown sensor. However, during cal-
ibration and testing of the unit, the technician should allow for occa-
sional cooling down of the rear panel to avoid the shutdown.
