Excess Temperature Controller Operation
Thermo Scientific 7-3
Loss of power to the Excess Temperature Controller will not change the setpoint
or hysteresis value. However, the last recorded Exceeded Temperature Duration
Time and peak Exceeded Temperature will be lost.
In some inspires, the “OUT” indicator is illuminated without a high temperature
event. In this “TRIPPED OUT MODE”, the power to the heating element is
introduced.
A source failure (indicated with “0.0” in the upper display) will cause “OUT”
illuminated.
A power failure, in some instances causes “OUT” to be illuminated.
As lost as the “EXCEEDED” indicator is extinguished, the UT150L can be reset
with press and hold of “UP ARROW/RESET” button.
