2 System Components
2.1 Control unit
2.1.1 Characteristic properties
The control unit is available in three models preconfigured for different supply voltages.
The relevant version will be marked on the rating plate: 24 VDC, 120 VAC, 230 VAC.
On its front panel, the control unit is fitted with plug-in screw terminals to connect all machine
inputs and outputs, supply voltage, and the scanner.
 The screw terminals have been arranged on two plug-in terminal blocks. These blocks
are keyed so that they cannot be accidentally plugged into the wrong socket.
 When in operation, plastic caps cover the screws in the front. Wires to be connected are routed
from the top or bottom of the unit.
The scanner will be connected via a 6-wire cable to the scanner socket of the control unit.
