Excess Temperature Option (“B” Models)
he Excess Temperature Option, when installed, provides an additional,
independent temperature control system to help protect products from excess
temperatures.
Read this section carefully before using this option.
Control Display
When the Excess Temperature Controller (Mode UT150) is first turned on, it
displays only the excess temperature setpoint in the bottom display. Press and
release the SET/ENT button to show the duration time of the last excess
temperature incident. (See Exceeded Temperature Duration Timer Section.)
Press and release the SET/ENT button once again to show the peak temperature
measured for the last excess temperature incident.
Pressing and releasing the SET/ENT button once again shows the current
temperature measured by the controller in the top display; this may differ slightly
from the main temperature controller. The value shown in the bottom display is the
current excess temperature setpoint.
Pressing and releasing the SET/ENT button again cycles back to the first display,
of the SET/ENT in lower display.
Excess Temperature Option Features
1. Exceeded Temperature Duration Timer
The Exceeded Temperature Duration Timer measures the time that the
setpoint is exceeded (and power to the heater was interrupted) until the
hysteresis value is reached as the chamber temperature cools. This time
indicates when the chamber temperature exceeded the Excess Temperature
setpoint.
2. Peak Exceeded Temperature
The Peak Exceeded Temperature is the highest temperature measured by the
Excess Temperature Controller.
