3.2.2. Optional Protocol Plus Controller
The Protocol Plus controller has two displays. A dedicated LED upper display shows the
oven temperature (Figure 4). A two line LCD lower display provides information on
control status, high limit temperature and allows changes to be made to the control
settings. Review the Protocol Plus Controller Owner’s Manual for more information.
3.2.3. Hi-Limit Instrument
The LBB Series Oven is equipped with a Hi-Limit instrument (Figure 5). The Hi-Limit
instrument protects the oven or product by discontinuing the heating process when the
Hi-Limit is exceeded.
Set the Hi-Limit instrument to a temperature 10°C - 14°C higher than the control
instrument setpoint, or to a temperature that should not be exceeded in the process. If the
setting on the Hi-Limit instrument is exceeded the heater shuts down. See Table 2 for
explanation about the Hi-Limit instrument.
Reset the Hi-Limit instrument by pressing the RESET button
on the instrument.
