3) The Programmable Temperature Controller sensed a temperature higher or lower than its
built-in limits.
The following paragraphs provide further detail.
VIII. Open Sensor Error
If the sensor fails or an open circuit condition occurs (infinite resistance), the unit will cause a
probe error as follows:
0.rtd
NOTE: The controller will intermittently beep. This error message could be momentarily
preceded by either of the following displays:
The Programmable Temperature Controller will stop control and will stay in this state until the
problem is corrected. This is usually due to the temperature probe not being plugged into the
Programmable Temperature Controller. Once corrected, the unit will return to viewing the con-
trolled temperature.
VIII.2 Thermosel Overheat Error
If the sensor becomes dislodged from the Thermo Container, or if the sensor is left out of the
Thermo Container due to an operator error, or the Thermo Container coils become open, and the
Programmable Temperature Controller is not sensing a temperature rise while dispensing power
to the Thermo Container. It will display the following message after approximately a 3-minute
delay:
ProBE
The Programmable Temperature Controller will stop control and will stay in this state until the
problem is corrected. The only way to correct this error is to power-down (turn off) the Program-
mable Temperature Controller and then turn it back on.
