3.2.6 Overheat Reset Switch

Figure 5.  Right Side Panel

If the unit is operated at high temperatures in elevated ambient temperatures, 

an overheat condition may occur. In an overheat situation a mechanical reset 

switch on the right side panel will pop and open the heater circuit (see figure 

5). The controller will still have power. While the controller will be demanding 

heat from the heater, the process temperature will fall continuously until it 

equalizes with room temperature. If an overheat condition occurs, let the unit 

cool off for one hour (leave unit on), then press the reset button, firmly. If this 

does not correct the problem, contact the factory.

3.3 Rear Panel Controls and Connections

 

Figure 6.  Rear Panel

3.3.1 AC Power Input

The customer connects the power cord to the AC Power Input on the rear 

panel.

3.3.2 Power Switch

The power switch has two positions, “ON” and “STANDBY.”

STANDBY                  ON
In the “ON” position, the entire unit is powered up.
In the STANDBY mode, the unit is powered down except for the fan. If the unit 

has been operated at high temperature and is then put into standby mode, 

the fan will continue to run until the probe well has cooled down to room 

temperature.
