position) the coil is not energized which allows the RUN signal to be passed due to the
NC contacts at pins 9 and 10 at J2. In order for the FEED DISABLE function to work at
the front panel, DIP switch S-6 must always be in the enabled position on the Base
Control Board.
2.1.2 START Pushbutton
The START (green) pushbutton turns on the machine contactor and applies power to the
motor controller. When this button is pressed, the machine will cycle providing that the
following conditions have been met:
• The machine STOP button is not pressed or in the locked position.
• There are no stop inputs being received from the Base Control Board or the Tabber Head.
• All safety covers are in the closed position (Tabber Head door is closed, Upper Transport
cover is down and closed, and the jam switch is not in a fault condition).
2.1.3 STOP Pushbutton
The STOP pushbutton (red) suspends operation of the system by interrupting power to the
machine DC controller. This is used mostly as an emergency stop button since depressing
this button will cause the machine to stop instantly regardless of the Tabber/Labeler’s
operating status.
Note: The STOP pushbutton has a locking feature by pressing the button and turning
clockwise into its locking position. When engaged it will prevent the system from
cycling. Should this condition occur, twist and release the locking mechanism to
allow base operation to continue.
2.1.4 JOG/RUN Selector
This selector button permits a choice between continuous and intermittent machine
operation. When the RUN mode has been selected and the START button is pressed
momentarily, the machine will operate continuously at the speed set by the production
dial. In the Jog mode, the machine will cycle only as long as the START button remains
depressed at the speed set by the production dial.
