What does Silko Er1 mean?

On Silko blast chillers, Er1 is the needle probe error shown on the EWBC1400 controller display. The controller has detected that the needle (core) probe is not connected properly or has failed, so it cannot read the core temperature of the food.

What does Silko Er2 mean?

Er2 is the cell probe error on Silko blast chillers driven by the EWBC1400 controller. It indicates the cell (chamber) probe is not connected properly or has failed.

What does Silko Er3 mean?

Er3 is the condenser probe error on Silko blast chillers using the EWBC1400 controller. The controller has detected that the condenser probe is not connected properly or has failed, so it can no longer monitor condenser temperature for fan control and condenser protection.
