Printer Management

The instrument XB570L can drive the serial printer XB05PR by means of the RS232 output. So temperatures measured during a freezing cycle can be printed.

The internal Real Time clock of the instrument provides time reference.

The “Prt” functions manages the printer by means of the following parameters: Prt: printer presence: (Yes/no) it enables or disables the printer.

itP: printing interval: (0.0÷30.0 min).

PbP: which probe has to be printed: (iP: Only the insert probe; rP: Only the thermostat probe; irP: Insert and

thermostat probes; irE: All the probes.

PtH: Printing during the holding phase (yES, no) yES = Printing enabled during the holding phase; no = Printing disabled during the holding phase.

NOTE: Although the controller is capable of several features ie. HACCP recording and output, it is intentional by Foster that these have not been developed to maintain the simplicity of operation for the end user. Therefore these features are not offered or supported.
