Power Supply
Table 9-4 lists the power supply performance values.
Type of Connection
Videojet 8520 is equipped with a directly mounted plug housing. A
connecting cable, approximately 1.8 m length, with matching connector
will also be included while delivering the Videojet 8520 printer.
Shaft Encoder Socket
The shaft encoder connected to this socket enables the Videojet 8520
printer to determine the speed of the product being printed. Refer to
“Commissioning” on page 5-1.
The standard shaft encoder supplied by Videojet delivers 2,500 pulses per
revolution. Four different drive discs are available for the shaft encoder. If
the measurement wheel is positioned directly on the product conveyor
belt, the resultant values are as shown in Table 9-5. The number of pulses
per meter has to be entered in the Adjustments/Installation menu.
Table 9-5 lists the values for pulses/meter depending on measuring wheel
diameter.
