5 CONTROLS
5.1 Controls Overview
The control system consists of a touchscreen interface and a Programmable Logic Controller
(PLC), which interact with each other and make the machine operate. The PLC controls manage
all machine operations. The screen interface located on the main controls enclosure door
provides operator control of the machine through software ‘pushbuttons’ displayed on the screen.
It also provides instructions on machine operation and displays error messages.
This section lists the standard controls on a WF30T. Actual control
functions may vary depending on options installed on your
machine. Refer to your Supplementary Manual and Section 15:
‘Options’
of this manual for further details.
